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 […]

[Current Regulator] Working « prototype » (en)
