Very nice assemblies and demonstration with the Velleman Educational Oscilloscope. The frequency of the square waves was illustrated nicely. I wasn’t aware of Mitch Electronics till I viewed your video. There’s a wealth of helpful technical information presented on their website which is a nice bonus to their kits. I could not help but notice that they updated their schematic on the through hole version of their kit with only R1 and R2. I liked reading the theory of operation in that R1 coupled with RV1 controls how fast the electrolytic capacitor, C1, charges and discharges which acts as variable timing control to the 555 timer. Thank you for providing instruction and for helping me broaden my knowledge.
Thanks for your kind words! And yes, the Mitch electronics web site is a trove of great practical information, freely available even if you don't buy one of their kits!
As you. say they are a 'fun little circuit'. But what a shame the kit supplier did not place a couple of test posts or pads to allow for improved connection to other projects and testing probes. But 'hey', I guess that is the point, go build a better one students!
Oh yes, and got you thinking! Reminds me of when I wrote a ton of shareware for Apple products in the '80s, my About box always read " if you don't like something here, create a better one yourself!" :)
True enough, I remember my first Heathkit SW radio kit in the late '60s, all those discreet parts! Then again, an iPhone based on tubes would be a beast to carry :)
You are much braver than me tackling the surface mount soldering, and much more skilled too. Great video as always CK 😀
Thanks! Lots of practice! Kits like I did a while ago in this link help a lot to get better. ua-cam.com/video/Ibi-Gz-3YYo/v-deo.html

Thanks, C.K. 👍
Thanks! And thank Mitch Electronics for creating these instructive kits!

@@CKHaun Wonderful companies and clever people give people the inspiration to play with their output! Bravo you.
I would NOT take such microscopic components; just use the normal size, they are beautiful. Nothing nicer than a 1970 diode or transistor.
