Electronic circuits that I have designed and built:
Solar Engine Circuit - Utra Efficient circuit runs small DC motor in a poorly lit room
Flickering Fire Light - LED or Bulb flicker shimmer randomly like candle flame or fire
Electronic Combination Lock - Very simple circuit allows up to 9 digits
LED boost switcher - Single AA cell powers two LEDs at constant current
Computer fan speed tacho out circuit - Add a fan speed monitor lead to any 12V two wire fan
LED buck PFM - Powers LED with constant current starting at 100mV over Vf
Constant Brightness LED Stroboscope - For measuring the speed of small motors
Strange LED sequencer - This bizzare but simple PWM circuit fades from LED to LED
Stepping Motor Driver - Minimalist circuit uses one CMOS gate and is reversible
Sound Blaster Preamp - Fixes that well known problem and needs no batteries
Rgb To Monochrome converter - Matches impedance of PC to CCTV monitor
