Edison 6w LED MR16 bulb (neutral white - 5000kelvin). Comprises 3 2W LEDs...just arrived by post this morning using a velcro adjustable bicycle handlebar mount made for conventional hand-held torches My aim was to come up with the simplest, cheapest, DIY design that required no soldering, no drilling, and takes about 5 minutes to assemble by anyone, and requiring just about no electrical knowledge.  I also wanted it to be easily taken apart and put in another housing if one just felt like a change in housing colour to match one's mood;), or if the housing got damaged in anyway.  The housing-change takes less time as it is just a matter of unscrewing the cap, pulling everything out as one piece, and sticking it in another housing. One of the reasons why i opted for this open-ended (the other end of the housing is open) curved design was for ventilation purposes as bulb-life can be compromised by all-round enclosure.   Additionally, the bottom-side being open enabled me to stick a sw

As stated in a previous article (ed’s on sabbatical), a2ed is moving on from singaporean affairs to wider vistas, and also figuring out how to construct a bicycle light as cheaply as possible, making it bright enough to rival most of the overpriced ‘Cateye’ bike lights out there, and making it as simple as possible for anyone to replicate or take apart for simple repairs or part-replacement without compromising too much on aesthetics. Well, it’s going on quite fine so far.  Did quite a bit of research on the net on bicycle lights, the electrical stuff behind it - i.e. watts, volts, switches, battery holders, wiring, etc - my background in sociology/psychology/art/music/photography isn’t really relevant in the technical sense unfortunately;)  Basically, what i ended up doing was to put together ideas from various tutorials, and come up with my own in the aesthetic and functional sense after considering and taking on the best of the ideas i’ve seen - that’s ‘progressive multiculturalism’
