Drive SCR thyristor by IC 555

This circuit gives a burst of pulses to fire 2 SCRs, when pin 4 is taken to 12V the SCR is turned on, to use this circuit you need 12V short pulses phase shifted with respect to AC sine wave on bridge.

This way you can control the bridge from near 0% to near 100% ON, that way battery banks can be charged, electroplating can be done, current and voltage can be controlled with opamps, thyristors are very rugged compared to transistors and MOSFETS in that order.

Electronic (foot)switch by IC Digital

This is a simple circuit for an electronic switch – I’d designed this for an external footswitch module but also with a duplicate button panel mounted. There are enough gates spare to easily make a dual version.
Output – 0v to +V Gate (switchable Mom or Tog), plus trigger signal(c. 1ms pulse) each time the button is switched.
The input should be a momentary (normally open) switch to ground.

Touch Switch By IC 4001 & 4020

Circuit Touch Switch By IC CD4001, CD4020
This be touch switch be simple again the circuit. It use integrated digital circuit is important equipment, and use volt power supply low just 9V. By use single metal, it works in the character turn ON and turn OFF. By when touch for the first time turn ON , but enough for the second time turn OFF. The circuit composes IC CD4001 take electric signal from a finger become the digital signal for change. The IC CD4020 be the counts two circuit or the divides circuit by two. Subsequently submit give the transistor drive Load next.
