HP 7132A Strip Chart Recorder Snippet
🕑 Added 2021-02-05 08:30:25 +0000 UTCHere is a small treat for the higher Patreon tiers. Sorry folks, I haven't done very much extra for the higher tiers. I'm just hopelessly behind all the time, and when I do small Patreon videos it is still non-negligible work, and it seems silly not to open it up to the whole Patreon audience. So you guys mainly give me more love, which is much appreciated. Here is a little raw snippet that fills the bill quite right though, as this is all the footage I have on this!
The plotter is simply connected to one of the dual voltage power supplies I repaired from the auction, and I turn the delicious 10 turn pots to make the pens move. I have only one pen at the moment. More are coming which will probably be dry, but I think I can revive them.
