Nano Hardware Hack to increase power to servos.

by MechEngineerMike

Hi everyone, hardware hacking question here. Should be simple but Im asking because the cost of failure is a burned up computer...but if this works this hack would be of use to other people driving servo powered robot arms.

I am driving hobby servos from an arduino nano breakout board & my application needs more current & voltage than the nano can pass.
So I want to pump up the 5v line by connecting it directly to Vin...The danger is passing >5v back to my computer via usb so I am trying to clip arduino pins to isolate it. Any tips of which pins to clip?

Can Crusher Help

by caveb578

I am working to make a dual push button program to actuate a can crusher for my kid so that he won't crush his little fingers. I have already created a functioning code but would like to make it so that if either button (or statement) is held down too long the output will turn off, the code below takes both buttons to turn on the output and if either button is released the output turns off. I just don't want him to get smart enough to tape/block one button on so that he only has to use one button to actuate the crusher potential crushing his hand instead of the can. Any help with this would be appreciated

int left = 2;
int right = 3;
int crush = 8;
int pbLeft = 0;
int pbRight = 0;

void setup() {
// put your setup code here, to run once:
pinMode (left, INPUT);
pinMode (right, INPUT);
pinMode (crush , OUTPUT);
Serial.begin (9600);


void loop() {
// put your main code here, to run repeatedly:

pbLeft = digitalRead(left);
pbRight = digitalRead(right);

if (pbLeft == HIGH && pbRight == HIGH){

if (pbLeft == LOW || pbRight == LOW){
digitalWrite(crush, LOW);

Help with the master thesis - Search for interview partners

by Gamzec

Hello dear community,

I am a student at the Technical University of Darmstadt and in need of your help with my master’s thesis. I am examining the topic of explorative and exploitative behavior in online communities and want to understand your actions on Thingiverse and how they are influenced by your personality traits.

Therefore, I am currently looking for interview partners who are willing to tell me about their experiences on Thingiverse in a 30 to 40-minute interview.

Between the volunteers (approximately 10 participants) a 50€ Amazon voucher will be given away as a small thank you. If you are interested, I can also provide the results of my thesis to you. The interview is possible in English and in German. Your data will of course be treated confidentially and will only be used in connection with this thesis.

If I caught your interest, please sign up with your e-mail address to the following doodle list at your preferred time. Afterward, I will send you an invitation to the Zoom call. It is first come, first serve.

Many thanks in advance!
