I also have the TC-1 component tester. It is pretty similar, except the Zenner button. Both testers are capable of decoding IR remote controls. It has helped me a couple of times. The TC-1 is half the price.

This is a nice one. It can test a lot of different components. I have tested diodes, transistors, MOSFETs, tvs diodes, zener diodes, resistors, capacitors, LEDs, double LEDs.

Ali Express declared this degausser was 220V UK plug. The plug fits into the US outlet of my transformer, so I used it with 115V. That shook the image on my PET CRT quite a bit. Does anybody know this model?

The big solar spot (AR4366) has erupted probably 20 times today. I guess, there is a chance of northern lights tomorrow or Wednesday. Would be exciting.

He still must have been trying to cover his bad smell, back then.

Not so long ago, that a boy sued his uncle for stealing his nose.

Ganz dicht sind die nicht mehr. Aber schon lange nicht. Als vor fast 26 Jahren der Bush gewรคhlt werden sollte, haben sich meine Amerikanischen Freunde komplett zerstritten, weil einer die Demokraten wรคhlen wollte. Der Freundeskreis ist dadurch zerbrochen. Fรผrchterlich.

I have mine since 2018 or so. My main application was heat shrink tubing. For SMD assembly, I mainly use a hot plate. After buying a 7โ‚ฌ hot air gun off ali express for heat shrinking, I have put the hot air station in the 2nd row, off the work bench.

Afzer quite a long time, I have found time and motivation to install the retroFuzion Mechboard64 in my Ultimate 64 elite (without II). The CBMstuff keycaps were transplanted from the C64 keyboard, that was in there before.

That would happen, if you leave the douche bag in the cat poo for too long. The moron raggery just lets the plaques dance in the Alzheimer organ.

I have eaten pretty disgusting stuff. But fugo oligarch is too disgusting. They are hazardous waste. You canโ€™t cut around the ketamine.

Yesterday was ฯ€ day. I have updated the os of my ultimate 62 elite II from 3.12a to 3.14. Just some minutes after Gideon announced the new version on facebook. C= and RESTORE now calls the ultimate menu. Cool :-)

You canโ€™t eat oligarchs, they are toxic.

Over 100 years of relation building was erased within a year. Putin is sacrificing 1000 of his soldiers every day. And he is murdering civilians in a high number too. That is worse than the USA. But who knows, what happens next.

And the worst was translating โ€žbyteโ€œ into โ€žOktettโ€œ. That is a band with eight musicians. Almost a big band, but definitely nothing inside a computer. If I was Gen Z, I would have been triggered.

I was into computing way before university. There was this lecture about computer technology and they translated things like โ€žprogram counterโ€œ to โ€žBefehlszรคhlerโ€œ and abbreviated it with BZ. That was a very confusing experience ๐Ÿคฃ๐Ÿคฃ๐Ÿคฃ

It seems to be really useful for making copies of stuff out of UV resin.

The German version is yellow. Usually I prefer the English original. I dislike technical terms being translated, because the German translations never really come to life.

Did they double the prices? I have bought quite a few JiffyDOS licenses while the past couple of years. It was always like 7โ‚ฌ or 7.50โ‚ฌ per ROM and it requires two of them (one for the disk drive, one for the computer).

I have used it for post repairs. It does not matter, if a post is 2mm thicker in a C64. I have also used those 3D printed sleeves for that. Most of the time, I have used to fill holes and cable burns, before painting a case.

I like epoxy putty. The only problem is, that it expires after maybe half a year. So, you have to buy it, when you need it and throw away 50%.
