Might be better if the spinning vortex of stars were projected inside the bowl?

Have they put AI in guns yet

@bornach@fosstodon.org avatar

@eniko @kojack
Technically an Israeli company has already put AI on a gun and which the British are now adopting. This is an aiming system using Machine Learning and not generative AI.

Went somewhere dark. No aurora. Bum.

@bornach@fosstodon.org avatar

Too much light pollution near the motorway. I'd have to drive pretty far along B roads to see any aurora.

I'm just gonna wave some purple LED strips about out of envy

I wonder if you can make this Ikea instrument with a dozen or so wire coat hangers

The one true USB3 connector.

@colinstu @disser @NanoRaptor
That's how you know it's fake. The USB committee would not have centered the solid bit in the middle of the equilateral triangle so that only 1 out of 6 orientations actually fits

Edit: just checked Alt text. Well played!

[denha] has made a new version of his marble catapult

The mechanism is so mesmerizing (requires viewing in slo-mo) I could watch for hours. Makes me want to build my own version so I can finally put to use the bag of tiny springs which my Dad had harvested from various printers and tape players over the years

As it's been 20 years since I made the original, I thought I'd recreate my "Monitor Slapping" GIF. Except now I'm slapping myself through time....

A man sitting at a computer, being slapped by a hand coming out of the monitor. He reaches in and slaps a younger version of himself on the other side of the monitor

operational transconductance amplifiers I bought on over 6 years ago. Date code doesn't make sense given that Intersil discontinued the over a decade ago. The real chip should have a diode across pins 4 and 5. Only one chip seems to have it -- but it is reversed. The rest have resistors between pins 1 and 4, and between 4 and 5, consistent with an op amp that provides offset null pins. Pin 8 also seems to be connected. Both 1 and 8 should be NC.

@bornach@fosstodon.org avatar

Someone has decapped one of these fake CA3080 ICs that have been selling on EBay as early as 2011.


The die mask claims to be LM4250. I already destroyed 2 of them trying to guess the pinout, but using the pinout of the LM4250 seems to work with 7 of them. They behave just like a jelly bean op amp.

@bornach@fosstodon.org avatar

I very much doubt they are actually LM4250 ICs given the all too common practice of mislabelling cheap clones of well known op amps. [IMSAI GUY] shows a few of the die masks that have been found inside many of these fake op amps

@bornach@fosstodon.org avatar

At least the single rail circuit works with these counterfeit chips. Maybe I'll turn them all into blinkies and Schmitt triggers.

Fake OTA chip in a solderless breadboard wired up with resistors, a capacitor and a purple LED which blinks about 1-2 times a second when powered by a 9V battery

The DC rails on this failed switching power supply from a wall wort AC adapter, were shorted together. It could be one of 4 components: 2 electrolytic capacitors, a surfacemount ceramic capacitor, or a surfacemount Schottky diode. Started desoldering each one and testing for the short. It cleared when the Schottky diode (SK26) was removed

I don't think I have a high current replacement diode in this form factor.

@bornach@fosstodon.org avatar

Desoldered the power MOSFET (N-Channel 2N60F) which still seems to be good. Not quite logic level but I might find a use for it in a project.

One of the surface mount signal transistors might have failed. I won't bother desoldering those as I already have so many.

I had a chat with Kevin at . We looked at robots and had a giggle together. Here is a teaser from our talk.
More coming up soon on my YouTube channel

For a moment there I thought had already happened this year and somehow I hadn't noticed
[NotEnoughTECH] finally released his video
