My first steps into the field of electronics. Converted an old Marantz tuner into a desktop powersupply. Delivers 12V, 5V, 3V. Just used an old PC powersupply. Allso put in a PulsWidthModulation from Velleman.
Here's the final version. The FM tuning knob is now used to dial my PWM. Cool!
Puls Width Modulation is a simple kit from Velleman, an can be used to regulate AC engines, or and this important for me , ti imitate the pulse from youtr ignitions contactpoints!
Here is a testing setup. In the back you can see the small PWM print, and in the front you see 2 Velleman electronic ignition kits. They reduce the current flowing trough your contactpoits, hence reducing wear and sparks. So better starting performance and smoother running. This really works. I'll spare you the explanation. Take my word for it!
Point of it all is to develop a testing bank for my ignitions. End in a next phase a programable ignition.
