It's time for another Gadget Master competition! And it's the last for 2011, can you believe?.
Before the next November / December Gadget Master competition, let's have another themed roundup of posts, on the subject of... radio comms (in the very widest sense!).
On another blog, a reader recommended a post in a blog by homo ludens electronicus - and what a blog it is! - see Power Inverter has more than a screw looseI needed a small transmitter, which would allow me to transmit good, old music into my AM-only radios. So, one Saturday afternoon I got into gear, designed and built a very crude, terribly non-optimized little transmitter. It's almost a joke expressed in electronics, full of poor design, so please don't think that this is the best I can do! You must see it as a quick and dirty 5-hour effort, because that's all the time the transmitter took to design, build, and test. Making this web page about it is taking much longer! I'm putting this thing on the web only because many people have asked me to do so, despite its crude design!

There's a nice 'Engineer in Wonderland'
post, on another of our blogs, that deserves sharing with Gadget
Masters, combining as it does two of our favourite topics: LEDs and
bicycles!The result is a Mark 6b LED bicycle headlight and, once more, learning more than I wanted to.
The +/-4° 6b is the result of those nice people at Cree spotting my semi-failure +/-4ۣ° 6a, which used some old Cree bits, and them sending me some shiny new stuff.
To re-cap, I am a one-Alice Crusade to have nice bright dynamo headlights on all bicycles, with proper main-dip switching to avoid dazzling fellow road users.
