    key chain laser power supply

    :) here are some more pictures in this one is a redraw of the siutable  circuit with the adition of the relay which is different  the relay here is wired up with a separate 9 volts dc input , so when the keychain laser is aligned with the photo transiter, the led turns off.  and ive yet to make...

    key chain laser power supply

    ante the dark activated circuit s relay is kept open by the laser shining into the fairchild photo transister and the transister can be housed in a peace of black tube so no other light can set it off unless it shines into the tube but ive got it set so the laser triggers it only  but ill find...

    Infrared Activated Switch

    if your looking for an infrared activated switch youll find a really simple one in the topic fairchild photo transistor data and if you want to see how simple it looks look at topic keychain laser power supply as the infrared  switch or light activated realy circuit that uses the fair child...

    Having problems uploading pic's.

    any problems viewing pictures to  and you get an empty square with a cross in its corner , just right click in the square and left click on show picture, in the list. if picture dosent show then its another problem, allso if theres no picture then at the bottom of the erea where the picture...

    key chain laser power supply

    hers some more better pictures, in these pictures ive retaped the wireing to the keychain laser and allso ive included the light deactivated relay circuit  so when the laser beam to the light deactivated relay is broken the relay switches on and turns on whatever is wired to the relay

    key chain laser power supply

    with the on button on the keychain laser taped down the on switch is left on and i used a small on off slide switch  at the battery clip to switch it on with

    key chain laser power supply

    in these pictures  are a simple modified power supply to power a keychain laser with.    now  the keychain laser takes about  3x button cell batteries and , if i was to power it from just a plain battery the laser will have a short life span so the idea was to measure the 3 buttoin cells battery...

    high voltage photo flash capacitor charger

    thankyou ante  i think i could make an infrared remote controll hv circuit  this simple idea  i tried first with my photoflash tubes and a transformer in rewverse mode and a 12 volts battery and the light activated relay i posted in the fairchild photo transister topic  now with the infrared...

    high voltage photo flash capacitor charger

    ante ive got my second high voltage photo flash capacitor charger to fiinish yet , and ive got one more hv trippler left and if i biuld another high voltage output ignition coil driver ill include the trippler and hopefully one of my 2 high voltage resister deviders, allso ive been collecting...

    high voltage photo flash capacitor charger

    great to hear from you ante im well aware of the dangers of the larger electro capcitors especially those large photo flash capacitors , i can emagine the size of the camera they came from ha ha ha just kidding,most of my capacitors used to be in my upstairs cubboard when it used to get hot so i...

    fair child photo transistor data

    hey if mp could put your clearer picture of the circuit in and delete my aged old one it would be better.  disregard my spelling error hotwater wizard  i was referring to the age of my circuit not me head ha ha

    fair child photo transistor data

    thanks hotwater wizzard  i think that i may of accidently uploaded may 2 of the same pics but if one is clearer then ill let mp dlete the other as 1 may be all we need, the resoulution of the circuit you uploaded came out better than my one did due to the age of my one nut thankss anyhow john
