Introduction First news the final prototype is working, with all modifications done. 2 days before receiving my Chinese LED the light bulb of my desktop magnifier died in some mysterious ways, simple coincidence or an Enigma of the Mystical… We will never know ;) By the way my LED current regulator seems to be right […]
It’s been some time I didn’t write anything here.
I have a working prototype of the current regulator. If you took a look at the previous post, I implemented a totem pole because of some stability problem on the Mosfet switching. It’s always a good idea to drive Power Mosfet with this kind of circuitry if you use an uC. But in that case […]
It’s a long long long sunday…. Oups I did it again ;) I took the time to work on this overkill current regulator, for the moment I have a draft of the schematic and a PCB, I’ll etch it during the week I think, but for now I’ll write the code for uC. As usual […]
It’s a long long long sunday. I was cleaning my electronic components stock and found this old high power LED I never used. I’m too lazy to order a current regulator from farnell :) , so why not design one. Here is a first draft, I will do a PCB on kicad and some test. […]
