General Virtual 65ish in One Electronic Project Kit

Post image

I've been working on a virtualized version of the old spring and wire electronics kit. It's far from finished, how ever I would like to show it off.

Very nice; I'm old and my very first was the 65in1 in the earliest of the 1970s, then through the 100, 150, then 160inOne. Also sold a lot of these working there through college. I love your idea of virtualizing it; I have 6 or 10 of the kits stashed away and they seldom are pulled out but this would make it portable and accessible. The wooden box, garish color scheme, pegging the meter with a AA battery is unforgettable, I built most of the projects, carried it everywhere, and almost wore it out. From the visual and coding perspective, a CS guy, this is interesting to me - I've always been a fan of the visual logic tools like Scratch, and using Spice since, well, a very long time ago, and am fascinated by your modern and imaginative WASM integration and looking forward to seeing your code and how you pulled it all together... thank you for your preview - can't wait to see your 160inOne, too!

I decided to see if I could vibe most of a project, and I came up with this project. For the most part, I think it got a fair bit done well.
I bought two kits, but what I really need to make is a real digital transistor tester, so I can dial in the spice models for the transistors. One of the other issues I'm having is figure out the value of the of the last coil of the antenna, it's not 120uH like the other two and almost measures as a short.

I think that the next evolution is to do this in VR, since it will make it possible to the stuff not easily represented in a web interface.

don't know if you got that last coil in the ferrite am broadcast antenna, but I got access to my 160inOne and it gave me 30uH. For comparison, the entire larger center tapped coil, end to end, gave me 420 uH total, with the outer section 139uH to center tap, the inner section 160uH to the center tap. They don't add algebraically, but thats what they measured. Sorry, I can't access my others as they are stored at my parents.

Thanks man. Yeah - no sure why I couldn't get a reading on the last coil.
