TRS-80 Model 100 with RARE Bubble Memory Expansion - World's First Laptop
Recently I picked up a couple Model 100 laptops, including one with a very strange expansion unit. This is apparently a "SoundSight Bubble Memory" from 1984. It was a somewhat rare add-on that gave the computer an additional 128k of memory (up from a max of 32k).
While I have not been able to find any information on the Bubble memory online, I did figure out how to interface with it! The associated ROM chip needs to be activated by running "CALL 63012" from BASIC. The user then has a "Bubble" program that lets you view different RAM pages and load/save files to and from the Bubble unit.
I was hoping to also use a TPDD Backpack drive (www.soigeneris.com/tandy-tpdd-2-backpack-drive-2), but r...

Robots And Lasers And Science Oh My! (Open Sauce 2024)

Open Sauce 2024 has been called an "Adult Science Fair", although it's not *that* kind of "Adult", unless you count a certain chess project. It's a convention for makers and inventors and creators to get together and show off all their weird projects, crazy ideas, and fun toys! This was the 2nd year the convention has been held, and the first time we attended. It's hard to describe just how cra...
I Crashed My Railroad Pump Car

The DIY pump car is still having some issues, this was supposed to be a test before taking it on a longer trip, but the test revealed more work to be done!

Satellite Hacking Cyberdeck v2.0
Просмотров 80 тыс.14 дней назад
My old cyberdeck computer had some issues, so I built another one! This is custom designed for radio and satellite experiments. It's also intended to be part of my exhibit at Open Sauce 2024 (opensauce.com/). The case is a Pelican 1430. The computer is a Raspberry Pi 4B, with 7" touchscreen. The front panel is laser-cut from HDPE and the "drive bays" are 3D printed from this design: www.printab...
Trying Meshtastic For The First Time

It's a short-range communication system for text messages that operates on unlicensed frequencies, so it's legal for anyone to use.

DIY Satellite Tracker Pt 2 (And Radio Telescope Struggles!)
Просмотров 20 тыс.21 день назад
This video started as an attempt to make my satellite tracker into a radio telescope, but ended up just being an update to the tracking system. I added solid state relays, an LCD screen, and a separate power input to avoid some of the USB reset issues. I tried writing some code similar to my miniature radio telescope project (ruclips.net/video/lVOTZxNCgTM/видео.html) but I still haven't figured...
Will Our Geodesic Dome Survive A Storm?
Просмотров 21 тыс.21 день назад
Since it's tornado season in the Midwestern US, I figured we should make sure the dome is secure! Last week we put in half the rebar anchors and most of the reinforcing plates, and this weekend we got all but two of the outer plates done. We also did some of the inner ones and drove in twice as much rebar. Hopefully the thing is now secure against normal thunderstorms! It probably still wouldn'...
Assembling A Surplus Geodesic Space Dome
Просмотров 36 тыс.28 дней назад
Last fall we went up to Carp, Ontario, to pick up a surplus radome! This came from a former NATO satellite facility, which is now used as a radio observatory. While I'm not exactly sure where this particular dome was used, these are frequently found on radar towers, satellite ground station downlinks, and radio telescopes. They provide protection from the weather for delicate antennas and other...
Is Creality's Falcon 2 Pro Laser Engraver Really New And Improved? (A Saveitforparts Review)

Last year I reviewed the original Creality Falcon 40W laser engraver and had a few concerns about it. This year, Creality has a new upgraded version, the Falcon 2 Pro. They've fixed a lot of the issues I had, including a much better enclosure and improved airflow and reliability. The laser is very powerful and fast, I was able to do most of my engraving and cutting projects in under an hour per...
Automated Weather Satellite Ground Station (Mostly Made From Trash)

    In my TRS80 100 schematic transcription (on github) I annotated the relevant resistors mentioned in the bulletin. Soldering required unfortunately. If you want to avoid desoldering the old ones, you can probably get away with parallel soldering 390 Ohm resistors in parallel (on the back of the board). Might be a tad less annoying.

    I still have my Tandy 200. It needs a new power switch, The 200 was one of the reasons that Radio Shack was in operation as long as it was. It was the first clamshell computer on the market, and Tandy Patented the concept. For the next 17 years, any laptop computer that was sold in a clamshell format, payed a royalty to Tandy to be able to sell that device. It wasn't the only thing they did right, but moving to selling cell phones pretty much killed the stores.

    Bubble memory was non-volatile, like core memory. I think it was also power hungry when in use. The chip had to warm up in order to work, and had a built in resistive heater.

    • @RNMSC
      @RNMSC 13 минут назад

      Most of these caps are from an era before China tried to steel the recipe Japan had developed for electrolytic capacitors, and got the wrong recipe. A lot of companies saw the low price on the new caps out of China, and saved a bunch of money by not buying the proven Japanese caps. Only to learn 5-10 years later that the caps would fail and take the board they are soldered to along for that ride. These caps are going to be good until the electrolytic in the batteries dries out. That will present a more observable problem w/o having to look for damage on the circuit board. (usually)

I was not allowed to touch it a whole lot but it is the first device I got to see work on the world scale with compuserve and he showed me a few games on there. Regrettedly it got tossed out a couple years back and I'm so wishing it had not been thrown out. It was 1 of 3 vintage computers Thrown out the other 2 was a Texas Instruments 99 a and atari ST520.
