@brouhaha@mastodon.social I never bother to get an FMRI because the idea that I am functional is absurd.

@paulrickards@mastodon.social @NanoRaptor@bitbang.social Ok, now who else wants a gigantic mouse to pose next to their regular sized computers? I'd personally like a giant Amiga 1000 mouse, and that reminds me that I'd also like a giant Amiga 1000 shaped house where the keyboard garage is where I park my vehicles.

@tubetime It really irks me that so much hardware is stuffed into a short-term use disposable product. ISTR Big Clive demonstrating that even disposable one-time use e-cigs have rechargeable cells (without the charge circuitry) because they're cheaper than Li primary cells.

I have daydreamed about (but never found the gumption to implement so far) approaching circuit-level simulations of both my PDP-11/34A and my VAX-11/730 in much the same manner, except implemented in FPGAs because I'm all about touching hardware. It's good to see that somebody actually had the gumption to create a circuit-level simulation like this.

@tpolecat@mastodon.social @rrmutt@mastodon.social @davbucci@mastodon.sdf.org The surprising thing to many seems to be that you often want a reducing lens (i.e., 0.5X, AKA a "Barlow" lens IIRC) on the objective to increase the working distance.

Fixing Breadboards for Wide Microcontrollers – Pico & ESP32 Edition

Fixing Breadboards for Wide Microcontrollers – Pico & ESP32 Edition: Many modern microcontroller boards such as the Raspberry Pi Pico or ESP32 development boards are too wide for standard breadboards. When plugged directly into a regular breadboard, they cover multiple contact points — with the Pico only two usable h…

@fozztexx@mastodon.fozztexx.com You can tell it's a prototype because it is purple and has blue wires! If it was green and had blue wires, then it could either be a prototype or a Tandy/Radio Shack/TRS-80 commercial product.
