Nice vintage kit! E&L made some really lovely experiment sets back then.

That looks like the adult version of those circut boards Radio Shack sold for young electrical learning using the little jumper wires, thumbs up, great video

Oh man, I bought a few of those from a surplus electronics place in the UK and handed a few of them out to people who were interested or for their kids, kept one for myself too because it's fun.

I have something similar but with more features. It was called the Wishmaker II and was bought from Jameco. The user manual is copyrighted 1988, and in addition to the pulser, switches, and LEDs it also has an analog multimeter, a waveform generator, a frequency counter, and +5 and variable +/- 1.2 to +/- 15 volt supplies.

These where all the rage in my University days in the late 80s. Years later when visiting my old school, there was a bin in the basement hallway full of these going to the trash. Should of picked a few up I guess though most of them where in rough shape, did pick up a nice galvanometer though.

I still have my HealthKit ET-3100 Electronic Design Experimenter. They made several different designs back in the 80s. This has 15/30VAC, +/-15VDC adjustable, sine and square wave frequency generator up to 20+kHz, and 1kΩ & 100kΩ pots. It was part of one of their Zenith-HeathKit training programs back in the day. And I still have some of the old dim LEDs and chips that I used with it.

That sounds like a cool kit to still have

Nice. I've never seen that "trainer" before, although many of their others. After monitoring eBay for a while I finally picked up one of their CADET II systems. It's a beast, made from heavy gauge steel and many of the signal sources and monitors are all discrete components. I had found the schematics and was considering building some parts of it myself but found that sourcing the parts quickly became more expensive than getting one second hand.

It's funny. I've been building a inspector gadget briefcase for such needs. Glad too know someone beat me to the punch.

I put the ANDY logic trainer board in mine with a velerman USB oscilloscope. I like having a quick kit too grab on the way out the door when troubleshooting afar.

At school in the UK - about 1970 - the physics lab had a kit - no electronics, but double-pole changeover relays (6 ?) DPDT switches, pushbuttons, blinky lights, and a motor with polar rotary contacts, at least a dozen all around. You could make a 2 bit adder, you could reverse the motor every revolution - aliens from space.

I have about 40 of those bag's. Only difference is all mine have a huge HP logo on the front of them. Think they originally had logic analyzer probe leads with clips in them.

I wonder if E&L changed their name or were bought by Global Specialties. The later versions of these boxes had the Global Specialties name. I've been looking for a way to teach digital design at our makerspace. The Arduino has made digital controls pretty easy, but I don't think much is being taught about actual logic design. Maybe a new version of the Pencil Box is in order.

I learned microprocessor programming on an E&L 8080A trainer. That was a while ago.

I am changing my job title to 'Logic Designer' now because of this 🤓 Edit: Also I just gave myself a sad when I thought "Oh, 1990, that is modern!" then I realized no, it is NOT modern 🧙♂

Yeah, that keeps catching me out too, it almost hurts when the mental maths kicks in and I realise how not modern the 90s are now

Over U-tube; the LEDs are sufficiently bright, regardless of your background illumination. Nose wet
