...is based on 3 key components, a broadcom APDS-9250, a STM32 MCU and a Sigfox transceiver. Together these components will count the pulses of a flashing LED over a 1 hour period, then transmit the count over the Sigfox network. The basic components have been tested. I have built several prototype devices that use the APDS-9250 and transmit the count vis Sigfox. This device is going to be battery powered, this specific version that you are going to design is going to be field tested so I can understand the power requirements of a working prototype. In the last month a Freelancer I engaged (on a different platform) disappeared without shipping me the finished article, I have included photos of that device for reference, but I don't have the actual device.

I would like to make a battery powered motor spin 360 degree each time a button is pressed as part of a basic robotics project. The project is very simple: (1) I press a button; and (2) the motor spins 360 degrees, rotating a shaft the motor is driving (ie turning it one full rotation). There are a few things that I need: - the design must be very tough and shock resistant (eg capable of off road jumps at high speed); - it must be waterproof (eg if it’s submerged in a puddle it must still work); - ideally it must be energy efficient (I’m not sure if that means a stepper motor is less viable, but it seems like a logical choice); - the 360 degree rotations must be precise (eg +/- 5% accuracy at most, preferably less); - the motor must be somewhat powerful to ...
