Radio Link for your robot to your computer (Cheaply).

Dan M's picture

          Some of you have noticed the small, low-priced transmitter-receiver pairs available, which seem quite nice for robotic links, robot to robot, or robot to controller or controlling computer.

I just bought a bunch of these units and thought I would let you know I have them available at a great price.

LMR won't allow me to paste the link here. Go to Ebay and search on Ublox GPS Receiver Board.

 

Super Capacitor in solar power supply - a few queries

Sydney-Floyd's picture

I intend to build a remote 'weather station'

The station will:

  • Be completley independant of any external power, ie, it will produce its own power via solar cell(s)
  • Measure temperature only
  • Transmit its finding over an RF link to an indoors reciever

Instead of using a rechargeable battery supply with charger circuit, i have decided to use a 35F, 2.7V super capacitor to smooth and store power.
