Inverter Circuits

Here are some good inverter circuits I fond they, oscillate at about 50 to 60Hz. They will probably handle up to about two amps any more and the will auto shut off.Have questions ask me leave your questions in the comment box or email me at ericgoodchild@yahoo....

Light Seeking Robot

Now most people I now tell me that they can not find a good light seeking robot circuit, but I have a very easy to build simple circuit using a 556 duel timer.Now this robot works on the same principle as the 555 oscillator circuit I posted in an earlier post the only difference is that I swapped the 50k pot for 20k photo resistors. You can...

Simple 555 Timer Circuit

This is a simple 555 circuit perfect for osculating circuits if you wont the strobe slower swap the 220uf capacitors for some 1000uf capacitors and if you wont it faster try some 150uf capacitor and you can also change out R1 to, try 470 or 910 ohms and if you have any questions ask my by leaving your questions in the comment box or email...

Schematic Mini PSU for Breadboard

The purpose of the project is to create a 5V mini Power Supply Unit for breadboard. The project can be connected to 8-18 DC power source, or 9V battery. During construction, put the components in as tight as you can, while verifying that you can in fact complete the circuit on the underside of the board without adding any wires. The main component in this project is voltage regulator LM 7805.To build this you need:Some electronics...

Control Signal generating clock

Evocation of this clock signal applies Astable Multivibrator circuit by using IC 555 as core circuit. this functioning Clock arranges rotation frequency of motor stepper. Output frequency excelsior from IC 555, rotation excelsior of motor stepper. So do on the contrary. Under this is drawing schematic diagrams from signal generating clock:...

Schematic RF and IR Remote Control

This PIC based remote control allow you to control up to 8 devices by this easy constructable remote control. The project very flexible you can use it as radio remote control or infrared remote control, depending on the components. Each device output can be configured to be momentary (turned on while you press the button) or latched. Latched...
