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.

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 "bare-metal" 4-bit computer for under $50!

For 4-bit Microcontroller Trainer V2.0

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 8-bit Microprocessor Trainer from the same seller, I lost track of about 4 hours the first day they showed up. Whether you're nostaligic 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)

Awesome value, rugged BASIC retrocomputer!

For SMART Response XE with Arduino Basic

I am SO happy with this delightful project! It provides retro BASIC goodness in a device that is easy to hold and has a better display, keyboard, and case than any badge computer, with ample memory and long life from standard batteries I'll be able to buy for the rest of my life (and works with rechargeable batteries too). The added commands to save programs, see available memory and battery, and the integration to turn the device on and off are nice touches, as are the adaptations to the make the best use of the device keyboard. It's reminiscent of programming BASIC on a Radio Shack Model 100 with its multi-line display, but is made from more recent technologies (no recapping!). The video and this page go over all the details and constraints, so there really are no surprises. If you want to have some old school BASIC fun, this repurposed device is an absolute joy to play with!

One thing that may not jump out at people from the descriptions are that because the Tiny Basic used is available as C source, you can use the same language platform on a Linux or other box (it compiles cleanly in GCC). This means if you want to debug or play with Tiny Basic in a different environment the code is portable too -- which is a real plus!.

All of this at a price/performance point that can't be beat, which is safely packed and quickly shipped!

Thank you so much to the creator of this delightful project for sharing it with us! If you ever do a Tiny Lisp version of this project I'll be back to buy more!
