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".

Current sources for LEDs: firsts DIY impressions
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 … Continue reading Current sources for LEDs: firsts DIY impressions
The classic hardware hacking: ATX power supply
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 … Continue reading The classic hardware hacking: ATX power supply
Blink an LED over the internet: the begginer’s low level approach
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 … Continue reading Blink an LED over the internet: the begginer’s low level approach
