The Tritium type 3 solar engine motor control

The Tritium circuit was the first (to my knowledge) type 3 SE. As such, it is quite experimental, and should be regarded as a prototype rather than the ‘state of the art’! Nevertheless, it does function reasonably well, and in some circumstances outperforms other solar engines such as the Freds that I have lying around.

Z-bridge by 74LS139

You can drop all off the transistors and resistors if your motors don’t drain too much current. You only need a 74F139 or 74S139 NOT the LS version. The chip can provide peak currents up to 100mA for a short time (<1 second) and to one output at a time. This is for normal connections. I don’t know how far you can go with this misbehavior. It’s nothing special, but you get the idea how it is done.

Touch Motor Control by SCR and Schmitt Trigger

This circuit designs for control DC Motor 12Volt. By use the touch once Motor as a result turn go to once. When use a finger touches the metal makes Schmitt Trigger Circuit take a signal from Oscillator Circuit and make a signal goes out Trig SCR Bias Current the DC Motor 12V then turn follow want. For power supply type of DC Motor this must be AC 12Volt Only. because of make SCR not bias during negative current there. And this circuit works not heavy DC motor, turn ? do not turn ? Then don’t have to stick heat sink give SCR1 for DC motor you will may use motor at use in an automobile all right. Request enjoy please, sir.
