Day 5 - Another calculator project that is waiting its turn! Nothing too special on the technical side about this one, but certainly a piece of history! #TWAAC

Day 4 - And digital troubleshooting on a revision 1 PCB. From my paddle game project: trying out a fix for a problem before ordering the re-made part! #TWAAC

Nixies! Some awesome calculator action here! This is the Sanyo caluclator, with the rightmost digit still bleeding into the leftmost during rollover, because there is a flaky short in it somewhere. #TWAAC

Day 1 - Here we have an improvised fuse; to replace an SMD part until the spare part got delivered. I still think this is one of the more hilarious botches I made so far... even though it's only temparary! #TWAAC

There are times, when I think that an electrical screwdriver might be a good investment... 🪛 #futureproject

My hotel room is "modular"? Should I try? 😸

I usually take a few days off after a con; this time I am in Hannover again. 👋

Yeah... YouTube changed stuff indeed; As @adriansdigitalbasement.com noted, something seems to have changed recently and it is rather depressing for creators; both those who make a living from it and those who do it as a hobby. I wonder where they are directing the views now?

Little known fact: Stage Hands also has feet! Can you tell that he was working oudoor today? #summertime

Attended day 1 of "Vienna Comix" today - which kind of doubles as a fur meet by now. The group pictures are getting more challenging for sure! #viennacomix #furry

Rate my botch? But hey: it works!

Strange... It shows weird diode junction values that make me think it's broken, but it apparently still does "transistory things"... #electronics

Look what I found! It arrived recently: An almost complete set of the TTL Pocket Guide I had back in the 90s. I am still kicking myself for loosing it over time. But since I only had the first two volumes, it's not as bad a loss... #MoreOnMastodon

PSA: I never seen a button cell explode before... but it seems to happen. Found one half in another compartment in my sorting tray, so it clearly must have jumped during the "incident". Not sure if it shorted out against something in there or not, but it would be the most likely cause IMHO.

Day 23 - And finally - since so many of you asked - here's what an (almsot) cleaned up workspace aroud here looks like. Picture taken during a live streaming test session. I really need to do more of these, but time is a very limiting factor... #TWAAC

Day 19 - A bit of electronic lewdness. In this unit, which looks similar to the Fluke Calibrator for nooooo particular reason, the PCBs are normally shielded and wrapped. For a first test, I omitted the shielding and present this nude picture! #TWAAC

Day 18 - Creative high impedance circuitry. Yes. Those are indeed two 100MOhm resistors in series. On the input! That is in the 8375A attenuator. #TWAAC

Day 17 - Another upcoming project. A bundle of coaxial cables had a fault in two of them. You can see that little dot between the tips of the tweezers? That's the core poking through where it tore. #TWAAC

Day 16 - Fluke calibrator again: the 1 ohm precision resistor. Used for current sensing (hence the size and heat sink) as well as the 1 ohm reference output. It's slightly higher to allow a trim pot in parallel. These seem to be hand picked. #TWAAC

Day 15 - I tried to save the calibration RAM of an HP meter before swapping out the draining battery. Alas, I accidentally hooked the "write enable" line to ground instead of 5V, so instead of reading the RAM, I wrote to it... so... successfully backed up a lot of zeros. Hmpf!... #TWAAC
