About

I am a maker from birth. I love playing and experimenting with electronics, robots, radios, and anything else technical. I retired from the military and have a Masters degree in Mechanical Engineering. I am passionate about teaching Science, Technology, Engineering, and Math (STEM) topics and started Subsystems to distribute education modules to anyone who wants to learn cool things.

A fun a very educational way to mess around!

For 8-bit Microprocessor Trainer

I originally snagged this because the concept of low level assembly programming felt like a bit too much to me. But this makes it loads of fun to tinker around and really learn the ins and outs!

I absolutely love the physicality of it too. It distills things down to the bare bones so that I can see all the moving parts, so to say.

Cool.

For 8-bit Microprocessor Trainer

I got mine today from https://www.myus.com/ to Germany.
It is great, I like it.
One question: Which temperature sensor is used?
I need the datasheet.
I tried to find "AF 5S" but no luck....

Priceless

For 8-bit Microprocessor Trainer

It's just so cool. I've had it for a couple years now. For years before, I had wanted to get my hands on an Altair 8800 or similar and play around flipping my own bits. I'm not sure I've ever spent $25 on something that's given me as much joy. I have it on my desk with me all the time. I was able to bring it with me on a Christmas visit to share it with my nephew who is interested in programming. Thank you so much for making it. Thank you for having it be so affordable.

Thanks so much Jarom. I love hearing about people enjoying this blast from the past!

You single handedly reinvented the pocket computer

For SMART Response XE with Arduino Basic

Such a cute little machine intended to celebrate the legacy of Tandy, Casio and Sharp pocket computers running BASIC.

Best Blinkenlights 8-bit Computer for under $26!

For 8-bit Microprocessor Trainer

When I impulse-purchased this, I think I must have thought it was a kit (I have a giant backlog of kits from Tindie), so when I first opened it, I was bummed. However, that turned around quickly when I powered it up and downloaded the data sheet and started programming it. Between this and the 4-bit Microcontroller Trainer from the same seller, I lost track of about 4 hours the first day they showed up. Whether you're nostalgic for the good old days of hand assembly, or you've never shifted left and are interested in what all the hullaballoo is about, this is a good option for learning about how real programmers used to practice their craft.

(I left a similar review for the 4-bit trainer; would recommend both, frankly)
