I am playing with LEDs for few month and during that time some little projects were born, but now I need a system to handle the logical part and the power distribution. I simply just can't use an Arduino board, or any other development board: I need a proper power handling embedded in a small space, … Leggi tutto Lino Project
It has been a while since the last LED related article. Was experimented the linear current source, its pros and cons and the field of application. Now arises the need of a small version, handling the same high power, things that are contrapposed in the linear regulator. I need something that I can bring with … Leggi tutto Tiny, robust, low cost, fail-safe LED driver: the Glighter-S project
A power constant current source, high speed, for power LEDs. Taken all the errors made previously, I tried a new linear based current source which should be kept "simple" and "fast".
Recently I found that today almost lighbulbs are made with power LEDs. And surprisingly most of them are made so cheap that the controller fails far away before its lifetime. At least for what I've experienced with few models. Most of them seems to work well, and I think that LEDs are the future for … Leggi tutto Current sources for LEDs: firsts DIY impressions
In a hot summer of a couple of years ago, trying to not thinking about the stifling heat of the afternoon, I put some efforts in a system which should drive a set of motors and peripherals by means of a single serial line. The idea consists in creating a sort of instruction set, sent over the … Leggi tutto An UART interpreter – sneak peek
