They say new endeavours need three people:
- Someone to build
- Someone to sell
- Someone to invest
Bsky leans heavily towards builders, is suspicious of the financial set and apathetic to marketeers. Which are you, and how do you find the other two?
Or do you try to wear three hats at once?

This is the appearance of a CPU when removed from a wafer. Shown here is the Intel 83C196LD CPU die—a 16K ROM variant of the renowned 80196—extracted from a factory-diced wafer but never completed with final packaging.

Here I'm getting the PLCCs mounted to the

Good boards! no blistering! (and good Rue for not going wild on the temperature)

I recently got a 256GB micro SD card for my #NintendoSwitch. My first console was an #Atari2600.
Atari's Breakout on the 2600 has a ROM size of 2,048 bytes, it is feasible to store not only the 7 million copies sold on the micro SD card but also over 131 million copies of the game.

#OTD Dec 23, 1947 the transistor was first demonstrated at Bell Labs by Walter Brattain & John Bardeen. The PNP germanium transistor worked to amplify a microphone & headphones. In 1956 Brattain, Bardeen & William Shockley received the Nobel Prize for discovery of the transistor effect. #histtech

I picked up this Brown & Sharpe 1-2” micrometer at an estate sale for $5! After some research this model no. 47 appears to have been manufactured for the US military somewhere between 1940 and 1945. Using some 1-2-3 blocks I can confirm it is still incredibly accurate!

over the last year, i've been reverse-engineering and documenting old Seagate hard drives from the 1980s. the latest one is this ST-296N from 1987, which is a SCSI drive that can store 85 megabytes.

recently, it confirmed a 20 year-old mystery discovered by hubble, finding that there are planet-forming disks in the early universe that are longer lived than they should be, given environmental conditions!
