@DanielBogdanoff I keep time by counting the clicks of my Weller Magnastat tips

Woke up in the middle of the night realizing I'd left my soldering iron on. What are yall doing to remember to turn yours off?

@FallingDj Music Man Stingray body 😛

What’s your all time favorite guitar body style? Mine is the “Falling Axe” with the runner up being the “Fender Strat.”

@matseng @RueNahcMohr I would not mix solder iron heat and 3d printed parts ;)

@RueNahcMohr Do you think those "lockable" tweezers could come in handy for some tasks? Maybe not for SMD soldering, but maybe holding a part in place while soldering a wire to it? But maybe helping hands with an alligator clip is better for that.

update on the tweezers! give them a try, tell me what you think! printables.com/model/1495787-…

@MarcoReps I know some products have the "not available in your country" label but that's normally stated before you buy. in my case the "German" price from the "official" distri was 5x the mousers one so I just bought it from another US vendor that just shipped it without asking :)

@vpme_de Yes, the Dear Marco Reps, email is actually from mouser and it arrived after a few hours of "Our customer support is reviewing your order". I am almost curious enough to call and try to find out what the problem is, there are some rumors in forums and reddit ...

Has this RoHS bs become a lot stricter recently? Or did I always pick lucky compliant parts by accident? Parts imports for repairs of my pre-RoHS equipment should be exempt anyway😑

@MarcoReps tried Mouser? I went through the order of DAC08 and I am at the final submit button, so far no issues...

they did not just put me on the naughty list for some die shots of 10 year old devices, did they?

@WestonBraun @MarcoReps @PCBWayOfficial @SGirl0311 using a desktop CNC mill with a diamond disk in a Dremel and slow passes at 0.25mm depth per stepping @WestonBraun would you have any idea why I only get 0.5V/A in the 1V/A range?

@MarcoReps @PCBWayOfficial @SGirl0311 After all the effort you went through to cut the ferrite ring for the little bee, you might be amused to see the production setup. A harbor freight mini chop saw mounted backwards with a diamond blade. Some 3d printed parts and a squirt bottle of water to keep the dust down.

New Eurorack module has arrived. The legendary Euclidean Circles from @vpme_de This is an important module for me because it completes phase 1 of my Eurorack journey which began all the way back during Covid lockdowns.

@IanSJohnston @TheDefpom Hi Ian, is that design public somewhere?

Made a wee GPIB Tester for myself just to make it easier to diagnose interface issues. Hi (green) & Lo (red) LEDs for D1-D8, REN, EOI, DAV, NDAC, IRC, SRQ, ATN & NRFD. Can be inserted anywhere in the cabling. PP3 battery required. @TheDefpom one on my way to you, saw you had purchased a GPIB tester recently.

@Raffzahn die Z-use Achse?

Z65 Fehlt nur noch die Z Achse und Zuse hatte auch gleich noch den 3d Drucker erfunden... #Hünfeld

@IanSJohnston I prefer my pads in mauve!

@eevblog @markgurman @BrodyFord_ their inventory of HP printer ink?

@markgurman @BrodyFord_ Err, what's worth $116M ?

Humane is selling itself to HP for $116 million and shutting down the AI Pin, bringing an end to a once-hot startup that aimed to replace the iPhone and iPad its founders helped create. Story with @BrodyFord_ bloomberg.com/news/articles/…

@MarcoReps Skeletor!

I am sure nobody recognizes this weirdo

@FallingDj Eloquencer is stated as 160mA on +12V, that's not that power hungry, Doepfer Monster has 4A, so you could put 20 of them

3/ calculator when determine whhere and what module I can put in his beloved #tiptopmantis case. But Deiter isn’t so kind. Each of the rails in the Monster Case has a very finite power output with a stingy threshold limit. If you want to put, say, an #Eloquencer on a certain

1/ Ewwww 😡 . . We’re friends and all but I’m not going to just show you my RACK! Let’s at least have coffee first. ANYWHO, I took the time to totally reassemble the Eurorack configuration in my #doepfermonstercase . BUT I failed to remember the FATAL FLAW inherent in the

@eevblog Loretta

POLL: What do you call the switch on an *AutoRanging* multimeter?

@baseck yes, that one is on the list!!!

@vpme_de You forgot this one

rhythm

@FallingDj I like 3 channels for eurorack development as you can have +/-12V and 5V at the same time...

@vpme_de Thank you soooo much 🙏❤️🙏❤️. I saw two channel models before but 3 channels will be amazing. Do you know if there is ANY oscilloscope on the market now (doesn’t matter if it’s digital) that can quasi-replicate the Tektronix 760 (or 760n or 740)? These are hard to find.

1/ ATTENTION DIY NERDS: Do most of you guys use some form of magnifying device when soldering? I can’t see well enough to solder properly with just my readers and want to buy a good magnifying device. I have quality magnifying goggles with four sets of magnification lenses . .

@FallingDj you can use most scopes in XY mode, actually older analog scopes might be better for that since the trace is continuous and does not depend on the sampling of the scope. my digital scopes are 25ys old and the XY mode is not good, I don't know how well modern scopes do that...

@FallingDj I use an Agilent e3631a. if you don't want to go for used there are similar (and more modern in terms of UI) three channel ones from e.g. Rigol or Siglent

@vpme_de Oh, one more question. I’ve always used a home brewed modified ATX power supply as my bench power supply. But I’d like to get a decent proper power supply. Do you recommend a certain model?

@IanSJohnston @BoscoMac no timers used here, just rising/falling IRQ on sync and falling IRQ on clock

@vpme_de @BoscoMac I think my issue is more related to lack of STM32 configuration knowledge probably, specifically interrupt timers etc!

Next wee project, using the R6581 DMM TFT driver board I made as a prototype on what I hope will be a successful HP3457A TFT LCD conversion. Using a 3.71" 240x960 pixel TFT LCD (display area = 91.44x22.8mm).
