At the System Source Swap Meet today and there’s printers. Free. So many ImageWriters.

@mmu_man @mac84tv Not seen yet.

That’s somewhat better. 100% infill (was 20%) and top iron at 20% flow (was 10%). Also using the TPU (85A) manufacturer settings file for Bambu P1S.

#RetroComputing #3DPrinting

Tried to make a stamp today with my 3D printer using PLA for the handle and TPU for the stamp. Results are meh. Maybe the flow rates aren’t right which leaves the gaps. I did use the iron feature on the top layer too.

@mac84tv @DosFox Serial FTW!😆 Wonder what the baud rate is.

@DosFox @mac84tv Please try it! My guess is it won’t work since it uses the external clock pin. I couldn’t get the ThunderScan working because it too relies on this pin. AFAIK it’s not broken out on the Lisa.

I think I've finished building my tiny plotter. It consists of modular 3D-printed boxes that snap together in colors borrowed from the JLPGA edition of the PowerBook 170.

In the top is an ALPS DPG-1302 2.25" wide receipt paper plotter. In the middle section is the ESP32 and motor drivers. In the bottom is a 18650 battery pack with USB-C charger. Hanging off the back is a roll paper holder borrowed from the Commodore 1520 plotter.

Got a vintage ALPS plotter? Two things you need to know.

1. The X/Y gears on the motor spindle are likely cracked. I had 3D printed versions available at Shapeways. Maybe they'll be available again soon? There's also brass ones too.

2. Pens are likely still available from Best Electronics in California. They have black and 4 color sets. They're NOS so it's a roll of the dice how long they'll work. Search for Atari 1020 pens.

#RetroComputing #PenPlotter

If it reminds you of your Atari 1020 you had, that's because ALPS made the plotter mechanisms and they use the same pens. The difference is my plotter uses the 2.25" wide variant and the Atari 1020 (and Commodore 1520, and many, many others) used the 4.5" wide type.

ALPS also made a 8.5" wide type that was used in many typewriter plotters. Yes, typewriters!

This tiny plotter prints in four colors, weighs 0.6 kg, stands about 10 cm tall, is battery powered, and prints over WiFi using GRBL.

I love these big chunky Radio Shack buttons. I got them years ago when they went out of business. The left one is latching on/off.

Edit: How could I forget the chromed panel mount power LED on the front 😍

Did you know the Amiga Kickstart boot screen is stored as vector data? It uses only 412 bytes. 💾

#RetroComputing #PenPlotter

My tiny plotter works! I finished most of the controller board last night. It’s running GRBL for ESP32 so I can send jobs over WiFi or BT. Still some clean up and tweaks to the case to make maintenance easier.

It follows B. Dring’s project from 2019 but modified for this tiny plotter.: https://www.buildlog.net/blog/2019/09/inktober-2019-project-post-1/

What should I name it?

#RetroComputing #PenPlotter

Been working on a case for the tiny ALPS pen plotter mechanism. It takes 2.25” wide receipt roll paper. Electronics will go beneath. Might add a roll paper holder. Maybe a battery pack too?

Welcome to MontaVista Linux 3.0, Professional Edition

Rate my battlestation!

This is a Sony Anycast Station AWS-G500HD from 2007. It's essentially a Sony luggable PIII 933Mhz PC that runs Linux 2.4.20 with a ton of FPGAs to do the heavy lifting of a video switcher. Plus glorious physical buttons, faders, dials, and removable keyboard. Oh, and a jog wheel.

#RetroComputing

It's an "install an old version of Linux" kind of day. TWM really takes me back..

TIL the Kensington Turbo Mouse can use a billiard ball.
