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
If you like playing with lab instruments, enjoy to make things and design electronic stuff, you are probably attracted from the idea of create a new powerful (with some limitations) bench power supply by using an old ATX supply. Moreover, I need an high power supply to test my motors. For sure, building your own … Leggi tutto The classic hardware hacking: ATX power supply
In this article we continue our road to the IoT approached at a low level, or better, at bottom-up approach, that will be applied in the future to my UART interpreter. Here I will talk about how to drive an LED over the Internet. So as always I'm using Python libraries to get things done … Leggi tutto Blink an LED over the internet: the begginer’s low level approach
