    Blind to see through feel project, help

    Hello friends, I have begun a project of mine to develop a prototype for a device to assist the blind in seeing and navigating. The premise is to use a depth camera (kinect) to extract pixel depth information, and convert that into a mat on their back which can imprint the depths onto their...

    Arduino DC Amplifier Help

    Hello I am currently working on a project whereby an output pin of the arduino needs to control the blacking out of shutter 3D glasses. I need to deliver ~9/10V to the shutter glasses to blacken them and then have them fade back to transparent. I have this mocked up using an LED for now, using...

    Thank you for that, your help is really appreciated. One question, the particular model I have uses an input of 4-20mA (rather than 5v) in order to trigger the switch (the D model). Would the circuit you drew be suitable for this?

    Temperature Control SSR Help

    Thank you, I agree! The issue with doing this is using the mechanical relay on the temp controller. Reliability is a key factor with this design, and the purpose of using the SSR was to get an unlimited amount of switches rather than have the mechanical relay fail at some time! Don't know what...

    Temperature Control SSR Help

    Hello people! I was hoping someone could help me with solid state relay selection. I am in the process of building a control box for a fancy electro-melt spinner 3D printer. I need to be able to heat a heating element up to a certain temperature in order to melt the polymer. I have the novus...
