Simple CNC

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?

Simple math? Answered

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.

Simple lighting question (hopefully with a simple solution)

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!

Simple CNC question... Answered

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

Simple, speaker question. Answered

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

Simple Zapper Idea

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.

Simple AM transmitter

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.

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.

Designing a simple circuit

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

Help with a simple circuit

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.

How to make a simple sound activated robot with simple motions?

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...
