I do not know how to crochet - i can sew by hand (can't use a sewing machine!) but would like to make something that has to do with Cthulhu for my sister. HELP! (perhaps an easy Cthulhu plushie? or hat?)

Does anyone have any information about the three programs, Simple CNC, Simple Art and Simple Engrave. I went to the website, and there is an order page, but the contacts and support buttons are dead.  There is no way to get in contact with them. Before I checked this I actually ordered Simple Engrave and was told I would receive an invitation to the CNC forum.  But I have not received the invitation and have no way to contact.  And of course, no program since it has to be downloaded from the forum. Should I just start a grievance with Paypal?

I am on a budget of $80 and i want to make a guitar amp with volume control, gain control, and a speaker. can someone help me do this? please?

This is one of those crazy things put up on Facebook. From what i can tell most people are getting this wrong. But you follow the rules for simple math -- Rule 1:   First perform any calculations inside parentheses. Rule 2:   Next perform all multiplications and divisions, working from left to right. Rule 3:   Lastly, perform all additions and subtractions, working from left to right. So it is       3-18+2= -13    And yet people think I am wrong ??   I simplified it even more for them ---- 3+2 =5     5-18= -13  Why are so many getting this wrong?  Or maybe I am wrong---- time to go back to grade school I guess.

I inherited an awesome orange&brown 70's "painting" of the bay bridge complete with christmas-bulb sized lights set through it from behind to illuminate the top of the bridge and one of the boats passing underneath. The cord for the lights extends about 12" below the painting--it appears it was designed to be put over a wall socket (who hangs paintings at ankle height?). No wall sockets on the side of apartment hallway where I want to hang this anyway, so I am contemplating making a battery pack to light it up in the evening. I need an electronics refresher--how can I determine what type/size of batteries would be necessary? What other considerations should I keep in mind? Will post a picture when I return home. Thanks in advance!

Hi.... I need a simple salad recipes that only takes 5mins to prepare and serves. (no cooking stuffs) thanks Arie 

This is probably really obvious, but I wanted to know if there is a better way.  I was thinking about how I would go about making a simple "mounting plate".  Then I realized that wouldn't I first have to cut it to size and then mill out the holes.  But then the since I had to cut out the plate it kind of takes the point out of the cnc, because I wouldn't be very accurate for the outside dimensions.  So is there a way to machine the outside, even though it would be in the cnc's vice? Thanks in Advance! AI

I'm working on an super efficient portable rechargable lithium-ion usb charging pack (if that make sense). If I were to make an instructable basically all it would say is make this PCB and solder everything. Should I just post when I'm done on like a forum? The only reason this is complicated is because it has about 30-40 electronic components.

Just a simple knex slinky type thing a made

I just got a soldering gun, and i really want to use it. but my knolegde of electronics is limited (and so is my wallet), so does anybody have a cheapish, simple, and cool robot idea?

I'm currently building a small hybrid solar panel car for a school sompetition(runs off of batteries or solar), and I need a bit of wiring help, here's my problem and some other stuff. I have 2 SPDT switches and 1 DPDT switch. I'm using one of the spdt switch for on and off, the other to switch from solar to battery, but i need help for the dpdt. There's 2 sets of solar panels (2 pairs of 3 hooked in series, for simplicity sake, I'm just going to say 2 solar panels), and I want to hook them up to the dpdt switch and the motor and the battery so that: I can turn on/off the motor (easy), switch between solar and battery (easy), and switch between paralell solarpanels or series (what I'm having problems with), any help?

So I had an interesting site Idea while looking at my own persona (vanity) and though it would be great if we could choose our best instructables to feature on our own persona page. Along with that we could also have a coming soon box sort of thing as an option, that has a thumbnail and a little text so we can leave teasers about our next projects...

Back in the day my grandfather use to make all sorts of artificial lures for us.From a simple spoon like thingy over spinners all the way to massive 300g killers to catch cod in the sea.And we always got our fair share of fish with them.These days everything is fancy, full of glitter and sometimes even with bluetooth and flashing lights.Are there any websites that show how to make the traditional ones yourself?I know how to make my own flies and have enough ideas for the rest but there must simpler ways then what comes to my mind..We even used wooden sticks with some aluminium foil around it and a small piece of lead for added weight to catch trout and redfin...

Hello,I am a hobbyist , and I am looking for a simple circuit simulator that can tell me if my circuit is working well.Just simple to use not like those professional that are hard to use and oriented to professionals.Does anybody know about?thanks to everyone.

Just curios, is it possible to build a (very) simple guitar amplifier out of  2x2N2222, a 8 Ohm speaker, a battery and some resistors? Note: I have a guitar cable with another and cut off.

Hi    i am a very confusing guy and cant take decision easily so want to create a simple decision maker which helps to make decision whether to do or not

How can I build a simple alarm system for a garage using a 30 watt 12 volt siren, a keyed outside activation switch and an inside motion detector. 110 volt power in garage.thank yougarry

Does anyone know a super simple game console hook-up? I don't really know much about circuit boards, and electronics, but I'd like to learn. What I mean by simple is: a power supply plug for it, AV cable plugin, an on/off switch, controller ports, and game cartridge port. To be specific, I'd like to be able to build a smaller, simpler version of a Sega Genesis, or N64, or whatever.                                                             --- Thanks!!

Hello, I am trying to make a simple comparator with a LM339N. I don't understand what is wrong with the circuit. The output is always low, even when the inputs are reversed. The schematic is attached--the schematic doesn't include the two 100k ohm pull-down resistors on the inputs.  Thank you.

I'm trying to figure out how to make a hooded towel for an infant/toddler using a bath towel and a hand towel. I can't find anything online that gives instructions for putting one of these simple things together and I really don't want to spend $40 at a specialty shop to buy one ready made.

In the new look editor, I cannot believe no-one else has noticed that the "Delete Instructable" button actually says "Delete instrucable"! The top right button. It's plain as day.

I am wiring some LEDs in series-parallel using a 9v battery. The schematic I've been looking at online as a reference shows resistors being used but doesn't say what size. Here is the layout: |-- LED -- LED -- LED -- resistor?--| |-- LED -- LED -- LED -- resistor?--| |-- LED -- LED -- LED -- resistor?--| |--9v-----------------------------------------| I assume it's a simple calculation but I haven't worked with this stuff in a few years. Thanks in advance.

I need a way to turn on an LED after a certain amount of time (e.g. 5 minutes) then keep it on until a momentary switch is pressed. a very low power consumption if possible, because it's going to be wrist mounted. thanks in advance

Hi,I was invited by GoWithFlo to add this project to the FullBellyProject group. From my understanding this group would be an ideal place to discuss improvements to the design and more importantly test it in the field.Please don't hesitate to ask any questions and provide any comments!Thanks!Kevin.

This is my first topic, so huzzah for me...Attached is a picture of what I was imagining instructables to be with forums. Now that there are forums, I figured I'd show it.. But then again, Cassandra still isn't here anyway..To get to the forums now is clunky and seems thrown in, which it probably was...

Alrighty, I'm a n00b to this world but I'm really into it. I just bought a simple amplifier kit and put it together. It is a stereo amp but I am only getting output to one speaker. The only problem I can think of is how i rigged up the inputs. I took a 3.5mm jack and combined the ground from the left and right channels. Can you not do that? How do I fix this without running two individual mono channels? Thanks in advance!

Hello  , I need help,I am posting schematic. I don't understand ,that   how program counter know some instructions  (jump , branch , subroutine call ) I have attached two diagram.look the 1st diagram.I am using 4 counter. how to improve that circuit for program counter .

To print out a pcb circuit you need magazine paper, a transparency or photo paper. Well I was just wondering if I can just take magazine paper out of a actual magazine if its a blank page and print right on to that and then iron that on to my pcb?

So...Basically... I wanted a light up by my pool. I want to program it to be pressed, turn on, then after 30 seconds turn off. (this way we can walk down the stairs without tripping and dying at night) How would I go about this?? Please be specific - I'm kinda a noob! Thanks!

Today i made a shaking generator for a shaking flashlight.i am using a 5.5v 1F capacitor as storage device.but output of  the generator is 3v~6v DC.how i can regulate the output ≤5v?.i am looking for most simplest and cheapest method. can i use a resistor?

Uuhhh..I'm not really sure about this..i'm an electronics engineering studentand my instructor in Logic Circuit and Switching Theory requires us to make a project which will include logic gates.now i searched in the net for some ideas i found two..but i know i shouldn't copy their projects..can anyone help me?link2link1thanks guys!

Hello! I want to calculate the torque for my project.I will have 4 individual motors to move a vehicle around 10kg. Here’s the specs:Wheel weight = 100g Wheel radius = 3” Wheel axis radius = 2” Vehicle weight = 10kg Speed I want to reach = at least 20mph with ease.Because I’m using four motors, I’m assuming torque needed would also be 1/4 of total torque needed to move the vehicle.Thank you! I appreciate any help!

I have this Soldering Iron. It takes 4 AA's @ 6V, and 8W or 11W. My reasons aside, I want to make it into an AC Soldering Iron now. I have various Plug-in adapters, and the one I chose Outputs @ 9V, 100mA. So sticking with the 11W setting, the Soldering Iron: > 1.83 Amps; 6 Volts; 11 Watts; And the plug.. > .01 Amps; 9 Volts; .09 Watts; So, what are my options? I got one.. find a plug with a higher current output :P

I have a project that needs a 24VDC input, at only about 300 mA. I don't have any 24V power supplies, wall warts or anything else lying around, but what I do have is a 120 in, 24 out transformer, a bridge rectifier, and a large cap. Is there any reason why I shouldn't just use those? I'll put a fuse on it. I have some 317 voltage regulators but they dissipate too much to provide the full 24V. 317s are short-protected and the like, which obviously my little kludge wouldn't be, but beyond that, is it a bad idea? thanks,

I'm wanting to make the simplest phone ever that can play music and only receive calls, I've designed the simplest circuit but have never done it before, so far on my list i have. areal aux out charger hole battery micro sim slot micro SD slot microphone speaker 6 buttons= play button pause button skip & back up button receive call  end/ decline button i have no idea how to programme a circuit board or how to use a bread board and may need some help, but this is all i want this circuit to do and at a very small size.  can anyone help or tell me how, I'm happy to pay a bit.

Hello, All I want to do is create a very low, and reasonably audible hum or drone from this speaker ; about as loud as a person humming as hard as they can before their throat hurts and they start coughing. Is it possible to avoid an amplifier and just run a voltage into it so that it just makes a single tone as described ? If so: I found this big broken speaker in the road. As you can see, the Cone is missing a section, but the surround and spider are intact. The cone is credit card thickness plastic. Is it feasible to just patch it up with some similar plastic and contact adhesive; it does not have to be a good sound, just a drone. I realise that my grasp of electronics is child like and readily accept the impending abusive comments and links to the Google homepage. Thank you  FOH

I have learned about electricity in Physics class and that to up the voltage of a given source there has to be an alteration in the amount of turns of wire around some magnets. BUT... is it possible to do this same thing in my home on a smaller scale by wrapping wires around some of my powerful earth magnets? The reason for asking is that I want to increase the current flow so that it starts zapping when the wire ends come near, also I want to create a ground based bug zapper for fun that will allow the zap to travel through water (shallow puddles). Sorry if I'm missing some law of physics that renders this impossible for me but I'm not taking the advanced course for science and we only touched on  the topic electricity.

I wish to make an extremely small (size and part count) AM transmitter using only a few transistors and passive components. I wish to transmit an audible tone on a set frequency.I am thinking along the lines of a transistor flip-flop circuit oscillator, perhaps routed through another. It really needs to have less that five/six small components. DIP components are too big. Small electrolytic and other capacitors, transistors, and resistors are acceptable. Transmission distance needs to be at least 1/4 of a meter, but further is better. It needs to run on between 1.5 and 6 volts, low to middle'in milli-ampage im thinking watch batteries for a few hours at least. I have read the following article but as stated before it needs to be very small. https://www.instructables.com/id/Make-a-simple-AM-transmitter/Can anyone help me out with a schematic, thoughts or advice?Thanks in advance,-AndyP.s. I can work out transistor loop timings and I understand how the Amplitude Modulation system works. Current thoughts/plans (if you can call them that) are an audible tone switching a secondary transistor loop from high (no resistor in series) to low (resistor in series) power and back. The secondry loop will be switching at the target frequency.

Hi =)  I needed to use a rc car remote and receiver to power some relays on and off. The car is using rack and pinion steering so it  has four wires; Steering Motor Wire A Steering Motor Wire B Propulsion Motor wire A Propulsion Motor wire B  SO when i press the joy stick forward, PWA_A becomes positive and PWA_B becomes negative, driving the motor in the forward direction. Same for the steering motor when i press the other joystick Could any one give me a way to connect so that when i press the joystick in the forward direction, relay one energizes and when i press it in the other direction, the other relay energizes so i can control 2 relays  per joystick, ie 4 relays in total. Thanks!

Ok guys.. so i think this might actually be my first post ever here! Down to business... without giving away my design before I have a chance to build it and such, ill be a little general, and using a different scenario than my actual plan.. i hope you guys are ok with this. It will be an instructable after i get going, i promise you that. So I was hired (i'm running a small business doing custom LED work) to make a project for a league I play in. The premise is simple. We need a way to keep everyone informed as to who's turn it is for the game. As it stands, there is simply a matter of the players staring at you, or mentioning, "let's go!"  which is quite embarrassing. So the design is relatively simple. I have one button (LED center) and one switch per person.   The button signals that you've completed your turn, the switch (when moved to the OFF position [preferably OPEN] )indicates to the microcontroller, or whatever I design to replicate the microcontroller, to skip your LED button if your turn should come around again, and go to the next person in turn. Using the most simplistic way, how would i go about this? I may make a picture of my idea, but its really late and im headed to bed lol, so that will be done tomorrow.  I'll give another example, say there are 4 people at a table, and player 1 and 2 complete their turns. player 3 chooses not to play for the remainder of the session. Player 3 turns their switch off, and play passes to player 4. Player 1 goes, Player 2 quits like player 3 (switch goes to off position), and then it goes to player 4.  Pay attention to the bold in the previous paragraph. How would this be accomplished? Remember, an LED button is being pressed to signal end-of-turn. Any ideas or nudges in the right direction would be perfect. I'm not looking for a handout, so just suggest, NICELY PLEASE or link to related materials. I like learning, so handouts will not benefit me, unless you tell me WHY, so that i can remember it for next time, if there is a next time lol. I appreciate this you guys and gals. I take a lot of knowledge away from every instructable I follow along with.  --Mikel

Heloo, I have hassled with this since last year. I have googled over 9000 times, yet I still remain confused, and unable to find a solution myself. I guess it's prime time to seek help from others. What I have: Lazer; 4,5 V, 150 mA 2x motor; 1,5 V, 250-300 mA 1x motor; 1V, 50 mA (vibrator motor from nokia phones, and it might work with less) The idea: I made a.. Thing.. that had 3 small motors ( the phone ones) that had mirrors on them and the lazer pointed at them, which eventually reached the wall and made made pretty stuff on it.. But that was a prototype, held together with tape, and now I have decided to make a better one. The V2 of it is held together with screws, has better mirrors (v1 had small fragments of an old hard drive disc), better motors, and looks nicer. If possible then I would like to be able to control the speed of the 2 bigger motors( to be able to create different images) The problem: EVERYTHING!!! I somehow managed to make the V1 without any resistors without burning anything out, so it only had switches and wires. That doesn't seem to be possible with the V2 that I have planned. I have read almost everything on the internet about it, but I can't make much sense of it, so I figured if someone was to show me how it's supposed be, I would understand a little more. Maybe even finish the project. What I want: HELP. You may try explaining what I need to do, but all the laws are sooo confusing. I will appreciate any and all posts, be they not on flames. But what I guess would help me the most, is if someone managed to show me exactly what components I need, and where to place them.

Just want something to work with

Hi people im a 15 year old south african,i want to make a small,very very very very simple and self powered audio amplifier that can work with cellphones.as i sed im 15 and i dont know alot about electronics,so please help me remember the amplifier must be as simple and cheap as possible just say capacitors and resistor and tel me how to make it self powered.thanks in advance,o and 1 more thing please tell me your email address because i might have questions

Hi to everyone! I am new here and will really appreciate any help or advice on my project. Truth is, i am very new to electronics and thus, have little knowledge on how to proceed with my project. In summary, my project is basically creating a friend(robot) that will activate upon receiving electrical impulse from a mic. The motion it will have is basically the lighting up of LEDs (for the eyes) and the head tilting upwards (using servo or DC motor idk...) when sound is detected. However, i want the motions to be there for 30 secs even after there is no more sound before reverting back. I have done many research regarding this but it is just too complicated for me to understand. I would really appreciate it if the solution or advice is simple enough for beginner to understand. Also, i don't want "clap" activated, i want it to be sound activated like simply speaking normally. And i hope to avoid using micro controllers. I would probably ask even more questions in the future, so, hope i will get along well with everyone here! p.s this project is a very scaled down version because i wouldn't be able to handle the full scale electronics...

I have a small simple speaker - just the magnet part, with no wires - and i have connected the positive and negative terminals to a simple 3.5 mm audio wire. The speakers play sounds, but at a very low volume even when the volume is max. Is there anyway to increase it?
