Tom has designed this Magic Mote wireless sensor, that is available at Github:

I set out to design a wireless sensor PCB that could be inexpensively prototyped in quantities of 10. NRF24L01+ modules are exceedingly cheap (~$10 for 10), use very little power, and have sufficient range for most indoor projects. Low power MSP430 microcontrollers make an ideal partner for battery powered applications. I settled on the MSP430G2553, but the MSP430G2452 can be substituted whenever hardware UART is not required.

    It’s awesome what we can do with the G2553. I’ve been starting up and learning on it. Found a great MSP430 Tutorial that covers the MSP430G2553 and the MSP430. My next step is getting it to talk to a wireless transceiver. I considered the nRF24L01+ as well, but I am not sure if I want to go 900MHz or 2.4GHz.

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...

  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
