Object-oriented programming in Unity?

Hi people, My name is Cynthia and I need some help with Object-oriented programming. I have a project for school where I'am making a 2D platformer game with Unity. Where I have to make a base class and two child classes that inherits from it. I have to work with constructors, properties, etc . The problem is I kinda know what the constructors, properties etc do but I don't know how to put them together to make a game. Can someone help me, push me into the right direction cause now I don't know where to begin with. What I like to make is a Enemy base class with two sub classes (enemy 1 and enemy 2) or base class Item (sort of coins or power ups) with two sub classes (item 1 and item 2). If there is someone who can help I would be so grateful. (I program in C# and the game must be made in Unity). Sorry if this is not the right place for asking such a thing. Thanks Cynni

Color Mixing Cube

Yesterday I was fooling around in Unity 3d (Video Game Development Software), and I created 13 particle systems, that show how red, green, and blue light, mix into white.  Every vertex is a basic RGB color. The colors shown are Black, Red, Green, Blue, Yellow, Cyan, Magenta and White. The colors parallel to each other mix. If you use Unity, and you want the Prefab, I have it for download.

Assembling a Development Team (VC funding in progress)

I will keep this short and sweet. I am in the process of getting VC funding for my company/video game. I am taking emails on all parts of the development cycle. I will be using the Unity Gaming Engine for proof of concept and possible the complete game. Being that funding has not be secured yet this will be "pro bono". Please note that once funding is approved you will be offered a full-time position.  You will NOT be asked to do any work without knowing you will be offered a full time position. A non disclosure agreement has already been drafted and will have to be signed before any discussion about the game can take place. If you are interested please contact me at dave.anders@verizon.net. Again I am looking at all parts of the development process. If you do not know the Unity Engine that does NOT disqualify you as there are many parts to the video game developement process that exist outside of Unity.

Video Game Idea

I have an idea for a video game which allows an opportunity  for the players to make money. The problem is that I do not know how to go about it. It would be a space flight\fighter were the players will be able to purchase spacecraft with the ability to customize them to their desire. Then dogfight against other players for cash rewards which they can use for upgrades or new ships. A leveling structure will be needed to allow for players to go against similarly skilled players. First, I would like to know if you would be interested in a game like this, Second, I am looking for people who would able to program, design ships and maps, etc. to get this going. Experience with Unity 3d would be best.

Ubuntu 14.04 / Kubuntu 14.04 graphics issue?

This must be just me, I cannot find any info on this weird problem: After a fresh install of ubuntu 14.04 LTS on my old Compaq Presario C700 (w/ 2GB RAM and a new 120GB xbox HHD (2007 vintage)), every time I open firefox or google chrome, the screen will go completely blank after a few seconds and the only way to make the screen come back on is to close the laptop and open it again. That makes it go into sleep mode then I can wake it up again. However, unity window manager appeared to have crashed and window borders and decorations are gone,along with the sidebar and everything except whatever windows were open at the time. The screen also has redrawing issues (things get drawn but do not refresh and go away, leer around after, say, a windows is closed.), and going into the CLI and running the command "unity" and "compiz" to restart it does not fix it. After updating everything, I still had that issue, so decided that ubuntu+unity wasn't worth messing around with anymore since I thought it was a unity thing not running smoothly on intel GMA (although 12.04, 12.10, 13.04, 13.10, and 14.04 worked perfectly fine previously! I had to reinstall ubuntu because I screwed up all the partitions on the drive when I did a HHD transplant. (200MB for linux, 110GB unallocated space, little bit of swap.)). Anyway I decided to try kubuntu w/ much lighter KDE, and was pleased to find out IT HAD THE SAME PROBLEM! X-( since it works perfectly fine w/o firefox running, I tried to disable hardware acceleration, nope, didn't work. I tried to use google chrome, nope. didn't work. All that did work was chromium, but I prefer chrome over chromium for... reasons. Chrome actually was working fine until I changed the theme of it and enabled the  This kind of reminds me of all the issues I had with Nvidia drivers vs linux... I am a bit afraid to screw around with the Xorg stuff, thats how I bricked linux in the long-forgotten past w/ Nvidia graphics. I will do whatever is necessary if anyone has suggestions.

How should I upgrade my PC? Answered

I'd rather a PC than a stupid xbox or ps3 because really PC's are 20x faster 20x better graphics free to play and mostly you can customize it!  Motherboard: P4P800-E ASUS RAM: 2x512mb (1,024mb) DDR400 184 pin 3.41GHz (I know I will get about 4gb later) CPU: Intel Pentium 4, 3.40GHz, 3408MHz Video Card: nVIDIA GeForce FX 5200 ("might" get a new one but I mostly model. not gaming) I don't care about the sound card I use my iPod for music :D So thats my setup in a custom case and what I mainly do is create 3d games in unity 3d and I will definitely get more ram (about 4gb) and really dont need a good graphics card for it but I want to start to use my pc instead of my xbox so maybe sell that and my games and all and buy a graphics card with that cash and I'll be set. so I "think" about 4gb of RAM and a new Graphics card would be perfect but you know I'm 14 know a bunch but not all so could you give me some tips. Oh and I'm running Windows XP Professional. But for now do you think having more RAM would be good for programs such as 3ds max, Maya, Blender, and Unity? currently its sluggish at times and crashes if I have to much.

Looking for constructive critism

I have not written an 'ible in a long while, but was recently so inspired I wrote...   https://www.instructables.com/id/Make-A-2D-Infinite-Runner-with-Unity/ Luck would have it that a game contest opened during my building of the first prototype (pre write up, to get things all worked out), which spurred me on even more. Anyways, I am wondering how I missed the mark completely, not even worth a feature. I have had way lesser projects featured....and well, I was only inspired to write this to share. Anyone who has been writing here for any amount of time knows that you need to be featured to be seen. I gave detailed step by step instructions with many pictures well commented...or thought I did. I did something original (Not many game making tutorials here, only 2 other unity ones, and they are on older versions.) I thought the demo game download was a nice touch.  So I am curious for suggestions on how I could spruce it up enough to be considered as a feature. I believe that people would enjoy the topic, and more importantly, I feel people would like to make this or use this as a springboard to their own version. Was using the robot a big faux pas? I see so many other features that use him and thought it was a good idea. Is the game itself that visually unappealing? Perhaps foolishly , but I love the look....I was...even more foolishly...proud of it. It wasn't something I just knocked out, but rather something that a lot of time went into. Time that was truly wasted if it is never even seen. Discouraged. Any suggestions  to how to make it better would be welcome.

Do I need to invert phase a second time? Answered

I'm building a guitar pedal and I am inverting phase with the initial buffer (TL072). I am then splitting the signal into two parts, dry (no effect) and wet (effect). Each of these will be output as separate channels (left and right) and not mixed back to mono. I plan to send each channel through its own 386 amplifier chip to boost it to a level suitable for headphones. So, what I am wondering, is, should I use the 386 to invert the phase a second time back to normal? Or should I use an op amp at unity gain to do that before I send it to the 386? Or does it not matter if I am not mixing the two signals back to mono?

Need a Game Development Team

Hey all, I'm looking to put together a small dev team for an indie game project that I'm planning. I'm working from the ground up here, so just about every role is still open. Experience is a plus, but I really only ask that you know what you're doing. The project will be a 3D Sci-fi/Fantasy RPG with a unique style of combat that combines the strategic skill-based systems of JRPG with the real-time fluidity of Western games. I'll put the project on a crowdfunding site like Kickstarter after I have a team and the completed GDD, so some stretch goals might include expanding to MMO or VR. I can give more specific details if you have questions. Roles to Fill: Programmer (C++, Unity 3D) Artist Level Designer Composer Scripter/Writer Voices (maybe) I couldn't pay immediately, but payment would probably be a fixed amount or a percent of the crowdfunding. If anyone is interested or has any questions, let me know.

Is there a cheap creation to make a 110v 9-45 mA power system?

I am looking at three ways for this right now. My preferred long game is a solar cell block (minor one, i am not sure of the power output calculator cells have, but along that size I am guessing) that feeds into a digital sine wave form for my output ( low end of power is fine.) I need the sine wave chips to do the build on a +/-110 V wave then, but the ampere I need is ultra tiny by current standards. The total power of this concept is about 1 watt. Perhaps a amp limiter off a wall circuit second as my second but probably easier choice. Reading up on some interesting theories, but to test them accurately, I need this base component(s). I will post the results of what I do with the device pas or fail, as I think it will be important to some of the current over unity power system theories bouncing around to have good well documented answers.

How to measure open loop H(s)? Answered

When designing constant current linear dummy loads, and when I was (attempting) to design a really nice linear power supply with op amps and pass transistors, I consistently run into the devil of the circuits that incorporate feedback. INSTABILITY! Especially if I use fast op amps, or MOSFETs, etc. My understanding as to why this happens is because I still have some positive gain at the point at the frequencies where signal the total loop has that dreaded -180 degree phase (gain margin) and then where the gain is unity and phase is at -180, again allowing that frequency component to be successively amplified (or never attenuated) as that wave whirls around the loop. However, with op amp circuits, how am I supposed to get an accurate open loop measurement, when the DC gain is so stupidly high the input to an op amp is essentially a comparator? http://www.ti.com/lit/an/snva364a/snva364a.pdf This article suggests whacking in a 20 ohm resistor and injecting a signal into it, and measuring the voltage on either side of it (?) How is this supposed to work? Is there a better method in something like LTspice?

Down to One Modest Proposal for the Instructables Site

Proposal 1: ***Addition***I seem to be the only one who feels this way, so it's probably a problem with my perceptions and not a real problem. So, unless someone else decides this is a problem too, I withdraw the suggestion. Originally it was that we not discuss politics or religion on the site, enforced by squid labs. Proposal 2: Assigned Group Contest. I'll explain: I've tried posting forum topics that somewhat unite the community following divisive posts (Heal the World, what's your favorite book, Maxims to live by, etc.) Allowing everybody to share things that they enjoy helps a little with unity. However, something that works even better(!) is collaboration. Heal the World failed at that. So this proposal would require people to sign up and be assigned to a group by Squid Labs, given strict limits on goals and resources, etc and let loose. Also, I think a leader ought to be assigned by squid labs, just like if you want to get anything done in the real world. The main point of the contest would be to build trust in the community and have fun, so the prizes might need to be well-thought out and mailable. Nothing builds trust like working together towards a common goal. Thoughts? Suggestions?

I Need a Game Design Team (Mobile Game Development)

Hey guys, I am looking for a game design team to help out with a project I am starting.  It will be a mobile game similar to Clash of Clans, but with many different gameplay changes.  I have a lot of the game planned out, but I don't want to have to learn all of the different skills it would take to make the game on my own.  I have some 3D modelling skills with blender, and will also do most of the gameplay design. People I Need: -Another 3D modeler to work with and help reduce the workload -A texturer -A programmer with the skill to put a mobile game together -An animator -An artist (for main map, interface, etc) -Possibly someone for sound; I can probably do that I would assume that the game will be created in Unity, but that mainly depends on the group's preferences.  If the programmer has the skill, he could just custom code the game, and it would definitely run better that way.  Anyways, whatever money is made from this project will be split equally between everyone except for the programmer; I know how much work that would take, he will probably get a little bit larger of the share. Reply with your email and I will send you the basic outline of the game. -Josh PS: Please, only native English speaking people; I've worked with non-natives, and I have found communication to be very tedious...

Op amps? Which one is best?

I have a couple op amps collected over a couple years, and I am working on a design for a linear power supply, but have stability issues, and a "down to -V" common mode input voltage for op amps is a difficult parameter to find. Constraints: * Inputs must work down to as close to the negative supply rail as possible  * needs to be stable when used in a feedback loop for a linear power supply design * low noise / offset / blah blah good good goodies?? Hopefully? I'm actively testing these in a basic comparator circuit to see how far I can get the inputs to the -vee (or ground) before the op amp stops working as intended.I have tested the LM324, LM386, UA1458TC, LM741, and a few of the LT one's. Only the first 2 work well on a single supply w/ the inputs near ground or Vee LM324; // slow LM224; // ditto, but in weird thicc package LM386; // slow LM741; // ancient relics of the past, not rail to rail by any means, sucks IMO. UA1458TC // ancient relics of the past, not rail to rail by any means, sucks IMO. LM318H; // it's in a fancy metal case :D TL072CP; // JFET inputs, limited output current and the output can't go below the noninverting input. TL2072AC; // ditto. OP37; // These things aren't even that fast and can't work at unity gain. OP27; // ditto LT1007; LT1167; LT1191; LT1363; CRAZY fast, 1000V/uS!!! Maybe too fast... LT1360; LT1112;

Having trouble measuring voltage with arduino.

I have posted this question before but I’ve made a few changes with my circuit with no luck. I’m trying to make a variable lab bench power supply with an lcd screen to read voltage and current while adjusting them. I’m using TL431 to have a 2.5v Vref and  a op amp in voltage follower configuration with 10M and 1M trimmer (Divider) on the input to finely calibrate 38v down to 2.5. The op amp is acting like a buffer. This is the code I've come up with: float volt; int sum = 0;                   unsigned char sample_count = 0; #define NUM_SAMPLES 10 void setup() {   analogReference(EXTERNAL);   Serial.begin(9600); } void loop() {   while (sample_count < NUM_SAMPLES) {    sum += analogRead(A0);    sample_count++;    delay(10);     }    volt = ((float)sum / (float)NUM_SAMPLES * 2.5) / 1023.0;     Serial.println(volt * 15.2 ,3);     sample_count = 0;     sum = 0; } Parts list: LM358 (for now, will upgrade to a unity gain stable op amp) 10M 5% resistor 1M trimmer Arduino Mega (Will use a pro mini in the final circuit) Breadboard (Will this effect my readings?) TL431 (2.5v Vref) Yes I now the LM358 is not suited for this application but I don’t think this will affect my readings by much, about 5% maybe. Will it? This code is gives me OK values at start but when I start to decrease/Increase the voltage. It lags behind and offsets by 1-2 volts on the reading. My goal with this project is to read (LIVE, meaning while changing voltage with buttons and see it change without any offset/lag) Voltage with a resolution of +-5/10mv accuracy and also read current (But thats for a later day). One last thing, I’m 16 so a lot of electronic terms tend to go over my head so please while giving an answer keep it simple if possible. Thanks :D

LFG that wants to learn to make games together

*FOR LEARNING NOT FOR PROFIT* So, I've got a few game ideas floating around in my head that I'd like to make, or at least have a hand in developing. However, I do not have the knowledge or experience yet to make these games, so I'd like to make a team that wants to gain experience working on a project that they can add to their portfolios. Should help those who have ability but no guidance especially, or who just want to have fun and make a game. 1) Modern version of Chromehounds with a lot more single and multiplayer features. Idea for the name: Wolf Pack Relative Difficulty: Easy Shooter with overall simpler animations and modelling due to no soft models such as humans required. Can practice making a large variety of models, sounds, stats for items, and hit detection. Also play around with various textures and allowing for players to customize textures. I know M.A.V. is being made but so far that isn't quite what I'm looking for. I have my own ideas on squad mechanics to add. 2) Darker story RPG set in the Mediterranean. Combat similar to Dragon's Dogma. Idea for the name: Road to Retribution Story Prologue http://roadtoretribution.blogspot.com/ Relative Difficulty: Hard Dragon's Dogma has a very awesome combat system, but that also requires a lot of animation skill to pull off. Models are harder because they are organic and so is texturing. 3) Science Fiction Adventure/Shooter using NASA models as inspiration for human designs (look up NASA FTL ship) Relative Difficulty: Moderate Blend of the previous two in terms of how easy and hard for the same reasons. No story/lore behind this yet, figured if I can get a group of people together I can always make the lore based on suggestions. 4) A Total War style game on the Wii U. I do have an idea on how it'd play but... Relative Difficulty: Hahaha, no. For a fresh team to work on that I would have to say no. 5) Whatever the team decides. 1-3 are ordered according to which idea i want done first. #4 I'd love to make simply to prove that the idea would work, but I don't see me getting a group capable of pulling off Rome 1 essentially with the control system of the Wii U, especially since I'd need to get a Wii U myself to test out the capabilities of the touch controls. Still, I'd like to think it's viable for a larger company. I myself am learning Unity and Maya atm, have dabbled in Blender a bit as well, but I am not far enough to carry the modeling by myself. I can however write the stories and dialogue much better, have an idea on how to break down the design process to increase the efficiency, and will ensure we don't overextend ourselves. Remember, the entire point of all this is to get a team to work together, learn the problems that arise working in a team with people in different positions in this industry, and most importantly, get some experience making a game. All while having fun. If it seems the game is going really well, we could crowdfund it, but that isn't the point. This is to learn the game development process by experiencing it outside of a classroom. Positions wanted, but not exclusive Modelers Animators Concept Artists Texture Specialists Sound/Music Developers Programmers Level Designers

Grow Our Own!- the big idea

Hey there Makers and Instructors! It's me, Maxwell and I have an idea to help feed people collaboratively, and I would like some advice on how to establish a collaborative barter network of people who want to or do grow food(mostly vegetables,herbs, and fruit,or even canned varieties for those who preserve) I call it Grow Our Own, or Let's Live! Participants would barter fruits, vegetables, herbs, seeds, plants, etc, and a climate of information,instruction,and encouragement. This might take place at either gatherings on weekends in specific places, personal meetings, or through a distribution system I haven't figured out yet.(advice?) There would be a system to enhance diversity, as well,so you wouldn't just end up with an enormous beefsteak tomato glut,( kind of a grow what you want, but please if there's space a little of this?) Ideally, this would increase nutrition, oxygen, biodiversity, provide useful growing information to a hungry somewhat ignorant populace , promote responsible water and waste use ,and bypass at least some economic cycle problems. I want to establish a network of smaller more local groups to also encourage people to propagate fruit, herbs, and vegetables,(especially heirloom varieties) and to instruct and engender a system of distribution and instruction. I definitely think composting is a strong part of this. I also think that trying to find unused spaces and getting permission to grow on them might help grow abundance, as long as vandalism can be avoided.Admittedly over my head. I would also like to encourage this for partial-subsistence growing in urban areas. I feel each apartment building roof, balcony and courtyard that can hold even transient plant life should be split between solar power, raingathering, and semisubsistance food growing. If this is done collaboratively, it will begin to snowball and will become more common.This would effectively improve life for some poorer people with less nutritional access due to economic factors. (If the fast food industry served actually nutritious food at it's locations at the prices it has gummed up America's vascular systems and organs, it would be one of the most effective nutritive food distribution systems in the world, instead of the casually despotic mutilator of bodies it is.(bovine AND primate) That may have sounded harsh, and I apologize if your love of a Double Supersize Mc Twinky Burger supersedes your desire to survive, that's your choice and I respect it, I was making an example, not inviting the hate. Houses with arable land now foolishly wasting water on lawns should be growing food. This not only could increase air quality and continue to localize moisture, but could reduce economic burden on many families, and therefore incrementally reduce municipal strain. This also can help mitigate graywater and reduce system load and waste. We have gotten too used to the system of aloof receivership in our modern societies. We must relearn to grow our own food, make our own things, understand the processes that keep us alive on Earth. I know you understand. Linear systems are unrealistic in a universe of cycles, let alone a world of cycles. We can live better by working together, because that's how the planet works. Sympathetic and Symbiotic processes naturally facilitate unity and if we work with what of the Earth we haven't paved over, or create more space to grow food in, we may counteract some of the damage we have done and stop so much waste. We may even teach people to eat more nutritiously, I'll bet. We must reteach ourselves to seek knowledge and wisdom rather than solace and escape, teach our children the ways of responsible stewardship of sustenance and comfort. I am going to put together what I can of the idea into a simple website soon. I want to reach people with that message, though I don't know if I am much of a frontman.So let's do it together. If we work together we can help each other survive better. Isn't that what's really important? Thank you for any advice, oh yes, and please don't assume I am Omniscient Superfarmer, I'm trying to learn too, any useful information will be appreciated! Let's Live! Cheers and Hope, have a great day! Maxwell (btw,I've already sent this, somewhat paraphrased in email form to: The Buckminster Fuller Institute.org, Pathtofreedom.org, The We Campaign, The Theodor Payne Foundation and many others, but any suggestions? You also may send it to whoever you think may help.) I admit I'm excited!

Unity 3D: Game Engine Currently Seeking: Programmers, Animators, GUI Art, Concept Artist, 3D Modelers, Writers, Composers, and People with great ideas. All work Copyright © 2012 by Boundless Game Studios Written by Casey Williams Version # 1.00 Wednesday, January 11, 2012 Overall Game Information: “Guardian” is a third person view and first person view adventure game that will allow the player to play as a hero on a quest to find the truth of the evils in his land . But, with the help of his guardian that watches over him from above. The guardian will fuse into your weapon and guide you through the hero’s world and conquer evil. On the way you will discover special fragments of fallen stars in all different sorts of ways that can alter your blade, skills, and powers. Our game will run on Mac and PC computers. The game will be free to play. Plot: A Valenian boy named Swen meets his Guardian (Bounda) that will need his help to find a fallen Guardian who has gone corrupt and has fused with his own partner from Valenia to destroy both Swen’s and Bounda’s worlds. So, the myth of the Crescents are true to Swen’s people. They believe that everyone has someone watching over them from the moon. Guardians or Crescents are not supposed to leave their world and travel down to Valenia or fuse body/soul/ and mind with their partner. Features: The game will feature live action battles, treasure hunting, altering Swen’s main weapon with rare fragments of fallen Stars, renaming weapons, voice overs for characters, currency system, text on screen system, choice of being good or bad, orchestral music, books with short stories and valuable information, some magic, and more ideas to come.. Genre: The game is an action adventure fantasy game with cartoon style art. Target Audience: The game is for anyone of any age. No bad language or gore. A little violence. Views: Guardian will be in third person view and in first person as well. Game Scope: There will be at least 5-6 towns or more to explore. The world terrain will be separate from the town. Different zones will load the player to new terrain scene or towns. etc.. There will be 6-10 N.P.C.S each at least in a town that will have some purpose in the game. Filler N.P.C. will be added to. There will be a lot of different weapons like Swords, axes, bows, and a few unique ones. Timeline: This project has no set date to be finished at any certain time at the moment. Common And FAQ: What is Guardian about? “Guardian” is a computer game being developed by Boundless Game Studios © that has an adventure/fantasy genre with a toon style. It features a character name Swen who’s name can be changed by the player at the beginning of the game. Swen will have to embark on a great journey with some help from his guardian Bounda. A fallen guardian from the sky has fused with the person he/she sworn to protect. Now chaos has been let out in Swen’s world. Tell me about the setting and the feel of the game? The setting takes place in a vibrant and colorful world known as Valenia. Also, a few glimpses of Bounda’s unknown world Anaira. “Guardian” will give the player a feeling of adventure, curiosity, and a rush in battle. The game art will be beautiful. How is the combat in the game? The fighting in the game will have preset combinations like swinging your weapon left, right, vertical, down. If you press the attack button once there is only one attack action. Press multiple times and this will give you more attacks with Swen’s sword. There will be more special sword attacks. You will also be able to have 3 items/weapons equipped at a time. This does not include your sword but does for shields. So be careful what you equip. Player can target enemies. Who do I play as? The main character is Swen and you control his role in the game. Which is the hero. Dialogue? Yes the game will have scrolling text and possibly voice dialogue. The player will be able to pick 1-3 choices to reply back with. Does Swen talk? Not literally but he does through the choices you make. He does have sound effects though. How are the camera controls? The game includes a button that will give u a fast switch between camera views. Ex. 3rd person view to first person view. Camera view will adjust to enemies that are targeted. Use the mouse to use the rotating view or simply don’t press any buttons for a minute to auto switch to rotating view. What are the main features in the game? You know the cool stuff? The team would really like to focus on the gameplay, story, and all the cool places, items, or weapons to discovered. The main sword can be altered many times (shapes of blades) which will give that certain sword an effect like extra damage, fire, ice, more magic, and more. How about getting to name your sword? Tired of using your sword and want to shoot something with a bow? maybe a blow gun? Well switch to first person and fire away! Selling treasure. Reading books to find short stories or VALUABLE information. Don’t forget the easter eggs.. There will be more features listed in the future.This game will be free for everyone. Doesn't matter if your new or a veteran. You can come and go on the project. It will be fun to have a lot of people helping out. I am aware that people like seeing progress before they are willing to lend out a helping hand.I will make sure everything goes smoothly as possible. My team mates and I talk on Skype everyday. I feel its important to get to know everyone as well and working with them. I don't want this to be work. Lets have fun. Please do not post negative comments. I'm looking for people interested and not downers. Skewl made the 3d model of the blue bird.

PSU design (major revisions): Transformer calculations help?

Recently I have attempting to design a proper dual-rail power supply that will allow me to set a voltage as low as +-1V up to +-30V in 0.1V increments at (hopefully) 3 significant digits (at least for the lower voltage settings). Anyway, this supply is also going to be current limited to up to 5A,again, it can be set to just about anything. I plan on using an Arduino micro-controller to set the output. In order to do this, I plan on using the analogWrite functions, or better yet, a legit DAC. There will be 4 outputs from the Arduino that will set the power supply output by applying a 0-5V voltage on the input of the 2 current limits and 2 voltage sets. (one for the negative rail, one for the positive). However, I have kept running into the same problem: how do I plan on driving this linear power supply with up to 200W*? My first idea was to use a a MOT, due to their high-power capabilities, and re wind the secondary with the right number of turns to achieve this output. However, I have heard that these transformers are not optimal for continuous running due to their poor and cheap design. (losses are very high). My second idea was to search around for a 250VA transformer. However, even until now, the VA rating confuses me. How does VA compare to W? I know this has something to due with reactive power, real power, and apparent power. However, I have no intuition of any of these 'powers.' How would I go about calculating the correct size transformer for the job, also, I am going to assume this linear power supply has the properties of a resistive load, since it is rectified and smoothed with a filter capacitor, so practically nothing should react with the AC power. (unless there is something more to the full-bridge rectifier setup I am considering.) This is when I came across unwound toroidal cores found on eBay for $25, the perfect price range! However, this has raised more questions! to start off, beyond turns ratio, I do not know now many turns I need for the AC side of things. I know intuitively and from experience, mains-frequency transformers do not work with only one (or even few) winding(s). I think this has to do with saturation, but I'm no expert by any means. and the inductive reactance of the transformer's primary. How do I calculate losses, inductance, and other important parameters of a homemade transformer like this? Things get very nasty when I look back at rewinding an old transformer. Now I have all these questions about inductive reactance, power, currents, magnetic flux and saturation, but also, about determining the original power rating of something like a very old small welding transformer or one from a large 10A car-battery charger. Is it possible to approximate the power by measuring the dimensions of the core? How close will this approximation be?  After getting frustrated with this, I considered alternative approaches. What if I purchased 2 ~20V ~6A SMPS (switch mode power supplies) connected them in series, and connect the center tap of my linear supply to the joining point between the 2 SWPS's? Would this be unstable and be bad for the SMPS if a load was connected between the 'outputs' of this new center tapped supply? Would any sort of balancing be required? Also, a bigger problem includes how this will be connected to my linear PSU design. With a low voltage @ high currents, I would be wasting a LOT of power, power that has to be dissipated away from the transistors. This heat can approach 200W, which is company unreasonable! Anyway, I would them have to either a switching preregulator, or modify the SMPS's so the voltage can be controlled easily and varied between, say, 3V to 20V. absolute accuracy is not required, close enough, and rest of my PSU should handle it. This becomes seemingly impractical too, and many other considerations need to be made. What should I do? what are the calculations and factors I need to know? i do not have an LCR meter to measure inductance, so trial and error is out. Does anyone here have experience at this? Help would be greatly appreciated! *The 200W figure was calculated by taking 40V, (What I believe would be a safe to allow some slack for +-5V voltage drop across my 2 shunts and transistors) and multiplying it to 5A of current for the maximum power output. ------------------------------------------------------------------------------------------------------------------- I have added an image of my current design, and I have modularized it the best I could. The YELLOW is all my current power-management circuitry. Currently just a transformer with many taps, going to a currently-undesigned switch box that will change the voltage on the output, which is then rectified and enters a filtering capacitor, finally entering the circuit.  The GREEN field is the voltage set. It is the most major part of the PID feedback loop, along with the ORANGE field. It works simply by feeding a voltage to the positive of a op amp configured as a comparator, and with negative feedback from the output. It then outputs a signal to the transistor, turning it either more ON, or more OFF depending on how the output voltage compares to the +Vset. The negative portion is largely the same, but the input voltage needs to be inverted so the output voltage is set negative properly. I was not able to use less than 2 op amps for this portion, unfortunately. The ORANGE field is current set. It works by measuring the voltage drop across the shunt resistor, and outputting a unity voltage that is referenced to ground, instead of to the positive rail. (It took me forever to finalize and perfect that!!!) Anyway, this voltage is then fed into a op-amp configured as a comparator to drive the transistor. The BLUE field is my switching regulation topology, which is controlled by both the ORANGE and GREEN fields. Do you like my use of diodes as a super-simple voltage or current selection switch? the op amp that outputs a lower voltage is the one that gets 'listened to' by the transistors. This way, current and voltage mode enable properly. This does add a small problem when it comes to powering the op amps, all of them have to be powered off of slightly higher voltages to swing the full range due to the voltage drops of those diodes. In the PINK field is simply a single-transistor solution to a constant current load. This allows the regulator to be regulated even at very low voltage set levels. This is why I am able to achieve a +-0.5V on the output (at least within LTspice) Finally, and most unimportantly, the light PURPLE fields have a simple ultra high-gain difference amplifiers that will detect if the output current and current set are the same, and turn On or OFF the respective LEDs. The green LEDs are voltage-mode indicators, and the red LEDs are to show when current-limiting mode comes on.
