The Piggyaxe Joule Thief Kit is fairly easy to assemble. The PCB is of very good quality, there are only 6 parts to be soldered (no coils have to be wound) and the manual is well written. The manual has to be downloaded from the vendors web page, a paper print isn't included. The Joule Thief flash light isn't as bright as ordinary commercial flash lights nowadays, but it runs on "empty" batteries (!) and has a nice case with switch. The shipment arrived after 2 days here in Switzerland (DHL courier). Unfortunately, the kit had included the wrong LEDs (red 5mm) instead of bright white 3mm LEDs. After getting back at the customer service, the right LEDs arrived after 1 week (free of charge). Summary: the kit is a good project for beginners, with good value for money. It is not very bright but it comes complete with a nice case.
