SD (software-defined) radio receivers use a bare minimum of hardware, relying instead on their software capabilities. This SDR project demonstrates what’s achievable, in this case a multi-purpose receiver covering all bands from 150 kHz to 30 MHz. It’s been optimised for receiving DRM and AM broadcasts but is also suitable for listening in to the world of amateur transmissions.

So when I got to Maker Day at Maker Faire yesterday afternoon, I was happy to find that Limor Fried, the founder of Adafruit, was giving a presentation on how to start your own business selling kits. This is a growing business right now, as people look for reasons to teach their kids how to solder, or just want to build a neat device. (Adafruit teamed with the Maker Store to offer the infamous TV-B-Gone kit that garnered a lot of attention at CES this year.)

via Ontario Science Centre "The partially preassembled clock is really fun to assemble. After one hour it made the "tick-tock" noise and our daughter was happy. The description is easy to follow. The accuracy of the clock is not impressive, but also not important."

"The rear suspension is a clever bit of kit, Mr Andersen must have realized the rear sub frame is a weak link when it comes to rust. So he disposed of it! Standard mini rear arms are mounted direct to the Cub chassis and use standard shocks, standard dry rubber cones and standard trumpets, but this is were it starts to get clever. The plate that the cone mounts against is adjustable by means of loosening the 4 bolts that hold it to the chassis and adjusting the threaded bar, this means you get the same effect as fitting hi-lo's - you can adjust the ride height.You can of course fit hi-los for the look but why not polish up and lacquer the standard trumpet. Another clever trick is the extending of the rear arms to accommodate 13" wheel cutting and welding them was not an option (MOT failure) so a 20mm plate is bolted to the are where the brake back plate bolts then the back plate is bolted to the plate further along tidy and effective it also extends the rear track by 40mm no need for spacers. As the shock mountings are standard any of the aftermarket shocks fit Adrian recommends Boge uprated ones from Mini Sport. See a Picture of the rear suspension HERE. "
