This circuit shows the voltage doubler working with a 555. LM555 has good drive 200mA, both Vcc and Gnd. 555 has the advantage of having […]
This circuit is an User Interface part of a Security Alertness Monitor that i designed decades ago. The circuits are here – Digital Circuits – Part 1 The RAM […]
This is related to the earlier post. This was done to save battery power. The output of some equipment may be in the form of […]
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 is a very simple -5V supply using one 555, useful for analog blocks using FET Opamps using low power. This circuit came up when […]
You must have read all the circuits and explanation on the other pages at delabs to understand this, as i cannot repeat the same thing […]
This is a demo of the popular 555 timer. you can try out the project on this page by a javascript simulation. Press the Red […]
