The April 2011 issue of QST features an article describing the PICAXE project developed by the OARC ("Canadian Club Digs PICAXE"). The article appears on page 61. It was originally published in a longer format in the Jan./Feb. 2010 issue of TCA ("Introducing Microcontrollers To Your Amateur Radio Club".
The International Space Station will pass over Ottawa tomorrow Wed 30 March.It will roar over at an altitude of 300 km and at a speed of 30,000 km/hr. We have authority from NASA to talk with the astronauts on board the space station. The contact will be made from Canterbury High School in Ottawa around 11:00 am local time. The radios from been set up in the school's theatre and both the directional and vertical antennas are now on the roof. The coaxes have been run and the computers have been programmed. All is ready to go. There is a Doppler shift of +/- 300 kHz during the orbital passage at the beginning and end of the contact which you may experience. That is normal. We only have one chance at this. Once the ISS is gone over the horizon, it's gone. So wish us luck! There should be media coverage on local newscasts Wednesday night if all goes well.

Here are Greg's club project photos of March 19 2011. The project is a small but very functional battery monitor device built around a PICAXE microcontroller. It was designed by Wayne VE3CZO.
