Hi Neil, Mmm. Not sure what topic you want to teach. And an hour is very little time= for explaining and building. And a difficult age too, you need something t= o grab their (boys and girls) attention. A flickering light might not do th= e trick. Maybe something with a lot of noise? At the end of the hour, a cla= ssroom full of noise will certainly be entertaining. When connected to what= ever box/soda can a tiny speaker can produce a lot of noise. Could you get them to build (or finish, if soldering is involved) a small t= unable sound generator kit (two transistors/one 555 plus transistor)? Or pe= rhaps a DIY electronic guitar (box + elastic bands + piezo pickup + JFET am= plifier + external speaker)? Great when you get the unwanted feedback! No so much electronics, but just electrics: I was once awoken by a boy driv= ing around his bicycle in our neighborhood. It's a local, yearly event that= children wake the neighborhood up very early by making noise. This boy had= a large loudspeaker box wired to the bicycle generator which is normally u= sed for powering the front and rear lights. The loudspeaker made a "Whowhoo= oo" sound because of the alternating current of the generator. When he drov= e faster, the pitch would go up. When he drove slower, the pitch would go d= own. Every now and then the tire would lose its grip on the generator wheel= resulting in amazing sound effects. Made me come out of bed to see what co= uld possibly make such sounds. ;-)=20 Cheers, Andries -----Oorspronkelijk bericht----- Van: piclist-bounces@mit.edu Namens Neil Verzonden: donderdag 5 april 2018 02:56 Aan: Microcontroller discussion list - Public. Onderwerp: [OT] Need ideas for teaching basic electronics Can use some thinking help here. I have an hour to teach kids (14-18 yr old) something about electronics. And perhaps have something they can take= with them. It should be hands-on and workshoppy rather than lecture. Any programming that's teachable in that short time would probably be costl= y. And I don't want it to be a soldering class, so if any soldering is require= d, I'd do that in advance. Also, this is in less than 3 weeks so I have to act fast. So... any thoughts on what I can do here?
