India's power grid is ageing and transition to RE and EVs magnify fragility, implying outages. Electrik Bee's PowerPod is a 30kwh clean, cheap alternative to DG sets that combines battery, convertor and cooling tech under a software, as a modular/portable product that saves ~$185/month in energy bills for our Construction/Industrial customers, in just 4x4 ft area. We are developing a 4.8KWh prototype, that one can literally take around like a suitcase, put it into your car boot, charge from and to EVs, to provide energy back to the grid, use for farm equipments, act as an additional source of power for Ebuses/trucks giving them an extra 40km range.

...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 ...
