My first group course at LOREM

A project log for Yet Another Electronic Lampyridae

and I ain't using a '555. Self-organising CMOS ring oscillators are cooler !

I have made my first workshop with the kids and we have had a great time !

Saturday afternoon (20160514) from 2PM until 6PM, I have explained, shown, demonstrated, how the few components of the MOSFET ring oscillator work. That's the resistor, potentiometer, the LED, the capacitor and the P-MOSFET. I started with the obligatory reminders about electricity, breadboards and how to use a multimeter.

After 2 hours, most of the circuits worked as expected ! Errors always happen (even I make them often) but thanks to a very progressive, careful and simple method, small errors are easily and quickly identified and solved. No magic smoke has been released, no tear has been shed!

I am thankful to all the people at LOREM for their enthusiasm, patience, trust and curiosity. Some of the kids are pretty skilled (not just boys) and this is very encouraging. I'll return with this workshop and even more (wink wink) as soon as I can!
