Hello, It has been sometimes I didn’t write anything here. I had plenty of projects and things to do ;) At the beginning of this week I finally receive my seeedstudio (a little advertisement for their great quality services !) and as usual it was perfectly synchronized with something I need ! I receive my […]
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 […]
Yes ! You need it. LTSpice Introduction and schematic A little feedback about Spice simulation, at first I was a little skeptical. My first spice schematics was not that good because of « bad » models (understand Ideal models), but more recently at my work I had to use it before prototyping some « complex » analog board (Fet, […]
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. […]
