    People getting away from Bluetooth as it is too easy to detect with OSH…

  • what about some kind of Litz Wire? https://www.newenglandwire.com/en/product-selection-guide/litz-wire-and-formed-cables/litz-wire-theory

    This wire is used when it is necessary to increase the amount of surface area without appreciably increasing the size of the conductor.

  • links are broke…

  • Now this is what I’m talking about. While the project I’m working on is not really inflatable robotics but I am using pinch valves that I found on eBay with big solenoids and I’m having to use a analog relay board to control it with and Arduino Mega and it would be nice to actually see a board that contains a mega and multiple solid state relays or some kind of Shield that contains more than just a couple of relays and that has solid state versions with correct protection for flyback and Emi suppression measuring the pressure is not clear that it would be needed for my application as I’m actually pushing fluids of the adult kind ;-) nudge nudge

  • The base and pwm unit. I want to make a shot despensing refrigerator. I have a few 12v pinch valve, rubber hose, these caps from china that allow me to use a 2liter soda bottle as a container, a pump to pressurize the bottle that has a pwm controller built right into it, and a pcb of 8 optically isolated relays.

    The user interacts with an application wirelessly to make a beverage choice and the pump will run until a relay is triggered to open the pinch valve for a predetermined time frame to fill the users glass depending on its size. Think kurig of beer, wine, or what ever happens to excite your tastes. Bottom line…. The arduino I have is limited on connectivity options without getting bulky and the Pi is overkill. Edison would be a dream for this project.

  • anyone wanna play table tennis now?

  • If there is no self, whose arthritis is this?

  • Zen… I haz it…

  • Good judgment comes from bad experience, and a lot of that comes from bad judgment.

  • A Zen master once said to me, “Do the opposite of whatever I tell you.” So I didn’t

No public wish lists :(
