I was thinking about using the big headlight style LED's for a Dinotte-esque light. From what I understand from the links above, I should be able to pick up a 700mA constant current driver and run a pair of 3W Luxeons slightly under capacity, from my Ay-Up battery? By my calculation it needs (2.95 ...

I'm curious why you don't like the compiler? Is it just an openess issue of the libraries Just that. I like to have the libraries open so I can fix bugs and learn how the devices were programmed. Libraries (to me) are as much about learning as using. Closed libraries means I don't have that opportu...

I use the Mikroelectronika developement board with MPLab and Sworfish. I don't much like the Mikroelectronika compilers although I've used them on small projects. If Mikroelectronika would open up their libraries I might reconsider.

Have you, by any chance, tried a search for the manufacturer on this site to see there have been similar issues ?

Overall I've spent around £600 on parts from Sure and haven't had a single problem (or faulty component). Check of course to make sure you can't buy the parts cheaper elsewhere (occasionally you can). Good to know, I was a bit concerned that they might not be up to Luxeon (branded) quality. I've us...

A good source of cheap LED's is Sure Electronics shop on eBay. They're in China but I usually get my stuff inside a week (and sometimes after just a couple days). Thanks for that recommendation. I've seen their ad's but never dealt with them before, it's good to know they're reliable. It's probably...

I measured the current and it was 14mA with a 2.08V across the LED. This was powered by 2.54V from 2NiMH AA batteries. I assume the LED doesnt have significant resistance, if this is so then I calculated they had put a 180 ohm resistor in series with it. I could not get any readings across either t...

Take a look at the Madison Summit, available in alloy (~£25) and stainless steel (~£50). It's very similar to the Massload rack shown below, except it has no platform on top...

I had a problem with the sensor (transmitter) in my old cateye micro dying on me, replaced it with a Strada and that works fine. I got a Profex from SJS on eBay for a fiver and tried it out. It's the most cumbersome thing in the world to set and as ugly as sin but I've now got it showing cadence whi...
