Fun haul. I need to get some of those carbon pad things. I could see them being handy. Also, couplers are really underrated. They're a great way to make something you don't have. I use hdmi, RJ, DIN and D couplers all the time. Might need to get some USB ones.

"long-term temporary cable management" - does that get filed next to Military Intelligence? 😄

nice haul of bits.

Nice haul, should keep you busy for quite a while.

Big spender these days, with the Mouser. Hey, at least you know who made each thing, and can get the data sheets.

@GadgetReboot 3 ай бұрын

in today’s economy, I can’t resist buying lots of things…. because I can’t afford to do anything outside the house! it’s convenient not having to put transistors on a tester just to verify that they are even in the ballpark of what they were marketed as.

I design/build Nixie clock circuits. Microchip HV5530s are perfect for Nixie applications, they work fine with minimal support components and minimal screwing around. Only drawback I know is that they are 12V devices (both supply and and data/control) so some level shifting is needed for use with 5V Arduino outputs. Your HV5122s appear to be very similar to my HV5530s. Not sure what that "using a ramped supply voltage" constraint is all about - the 5530s have no such note.

Im going to glance at the data sheets for the similar devices and see what the differences are, for the 12 V serial input I was thinking about maybe just using a transistor open collector up to 12 V as long as it can switch fast enough for the data rate, and I think there’s also some CMOS chips that can handle that sort of output but I don’t know if I have any of those around.

@@GadgetReboot CD4504s work real nice if you have some. Actually I think Mouser still stocks them. I've seen others successfully shift with weirdly connected FETs that apparently switch fast enough. I'm hazy on the details, googling FET (or MOSFET?) Level Shifter should turn up some examples.

@sootikins 3 ай бұрын

@@GadgetReboot Hmm. KZfaq seems to have eaten my reply. What I said was that a CD4504 makes a good shifter that does not mind 12V. Alternately, some people use weirdly connected FETs but I've never tried that. Googling FET (or MOSFET) Level Shift should turn up lots of examples. The most obvious difference between 5530 and 5122 is that 5530 has a blanking input - PWM it at 1KHz to vary brightness of the Nixies.

😮 220 volt. Wow. Almost spat my coffee on the table. Have not seen anything so small, that was so highly rated. I'll have to take a closer look at the datasheet to see how it is safety rated. I'm assuming there is very low current involved.

@sootikins 3 ай бұрын

Current *sinking* outputs, 100mA per output max, per data sheet. So not for controlling big heaters or something 😀

@sootikins 3 ай бұрын

Let me clarify something: that's 100mA per output with a maximum total current on the device of 1.5A, so you can't actually run 32 outputs at once at 100mA each.

8:48 OCTAVE FUZZ!! 😆edit --- actually is that a treble boost? I was quick to guess.

@GadgetReboot 3 ай бұрын

it is octave fuzz although it might have been adapted from something else. I was researching different ways to achieve the upper octave and it seemed like the full wave rectified transformer method may give the clearest result and it goes back to the old days although that may not be what we always want, there’s other methods where they do something just with transistors and it has harmonics involved and you can only hear it on certain notes or frequencies halfway up the guitar neck so I just want to try a bunch of things.

@@GadgetReboot yes! This schematic is based on the Tycobrae Octavia. This is the one that I based my Taco Octave Fuzz pedals off of alright. I saw the transformer, and the 3 transistors, but for some reason when I looked for the diodes I just gave up and second guessed myself 😆 I have a video on my channel where I test a sine wave thru this circuit on my oscilloscope. This circuit actually shows up here and there in many different forms on my channel over the past 4 years!

I think I remember seeing at least one taco video now that I think about it. I’m going to have to think of a name for whatever I come up with. that’s the hardest part.

@@GadgetReboot I "borrowed" the name from an older Japanese builder, but they "borrowed" the schematic from Tychobrae. The "original" Taco used an octopus for its artful centerpiece. I used 🌮
