mashup ideas: solar powered radio
From the maker blog a while back they ran a series of posts on joule theif.
Bill on the SolderSmoke blog ran a couple of articles on mechanically keyed transmitters, like the ET phone home rig, also a rew ideas around clock powered keying.
So my brain was buzzing away recently and it wasn't until I spotted the solar powered garden lights, that ceased to work a couple of months ago, that I thought about re-using them. The little solar cells only put out 0.8-1.1 volts. Three in series put out around 3.2 volts in full sun light. I need to go back and see what kind of current they can sink though...
To power something like an arduino keyed tx or a DC receiver with NE612, I would need a solid and regulated 5 volts.
It wasn't until this morning, on the irc channel of our local homebrewers, that I thought about mashing up the joule theif and the 80 meter DC receiver to make a solar powered radio =) It would make it limited to day light hours, but its certainly workable. Still have some other things to work on first, but certainly the next project on the list =)

Podcasts I've been listening to recently
Recently I've been listening to a couple of podcasts about HAM radio, homebrew, computers and Linux.
I have been hanging out for the next podcast from Bill N2CQR. Bill posts usually once a fortnight and keeps an interesting blog called SolderSmoke. Homebrew amateur radio, some travel log, some amateur astronomy and other related geeky things.
A couple of weeks back I found Linux in the HAM Shack, which is self explanatory really. Russ K5TUX and Richard KB5JBV, aim to walk you through all the popular things you's likely do with computers in HAM radio. Assume radio experience, but not Linux experience.
I have at least a hour bus trip to work and then another hour home again, so these podcasts help fill the voids in my head with useful radio thoughts =)
