01:53:31 <electrohead> I've had this on my list of things to get for years now lol
02:09:49 * arch puts electrohead on the deport-to-Mars list
02:46:12 <electrohead> :/

06:41:47 * Vampera catalyzes K
06:42:03 * K clogs up
06:42:27 * Vampera gets the rare earth plunger

17:41:14 <K> hello corrugated cardboard enthusiasts
18:31:06 <electrohead> Never knew I could be so enthused about a paper-like object :P
18:31:16 * electrohead hats K with an op amp from digikey
18:36:35 <K> is it in proper metal can?
18:40:25 <steve30> I got a free two pence piece from the Tesco self serve till today.
18:51:19 <electrohead> nice lol
18:51:29 <electrohead> K: nah, 8 pin DIP
18:53:04 <K> weak.
18:57:42 <Agripa3> 10 pin TO-100 metal can package or go home.
19:00:51 <K> a person of culture!

19:25:46 <electrohead> want to see my head(s)?
19:25:49 <electrohead> https://0xznc01.pw:2600/public/1759323193917.jpg
19:26:29 <electrohead> Agripa3: I could perhaps revise the circuit I'm basing the e-field mill build off of, and use a 'proper' op amp
19:27:39 <Agripa3> 4 cylinder opposed?
19:27:43 <Agripa3> Boxer or something?
19:28:09 <electrohead> Yeah, for my WRX
19:29:14 <Agripa3> There are lots of good operational amplifiers, including classic ones available, and discrete designs are competitive if you know what you are doing.
19:29:54 <Agripa3> I want to design an electrometer front end, but I need a low noise high voltage isolated power supply.
19:30:46 <electrohead> Well for what I'm doing, this is the first time messing with op amps at this sort of level. Once all parts are here, I actually may just design a board and make this my first project on my CNC router
19:31:17 <electrohead> And nice, looking to just get an off-the-shelf HV PSU or designing?
19:32:02 <Agripa3> Nobody makes a suitable power supply.
19:32:16 <electrohead> Ahh
19:32:37 <electrohead> So, more projects for projects
19:32:41 <Agripa3> Probably just going to have to wind my own magnetics.
19:33:32 <electrohead> I still have yet to wind a transformer, one of the few things left on the 'electronical bucket list'
19:33:49 <electrohead> Not sure if I can or can not wait to do such a thing
19:34:20 <Agripa3> I have a pile of 3C8 pot cores which I could use. Were originally gate drive transformers.
19:34:42 <Agripa3> Not exactly good for high isolation though.
19:34:57 <Agripa3> Maybe use two in series, but they are not tiny.
19:36:42 <Agripa3> I wonder where I could get smaller pot cores with the bobbins.
19:37:46 <electrohead> How big are they?
19:39:31 <Agripa3> Mine are like 1.25" I think, but looks like I can easily get much smaller ones.

22:14:53 <Agripa3> 3C91 is about right I think, but I will have to review my materials.

23:39:59 <electrohead> Right on
23:41:42 <electrohead> That's on the list now, although listed as "random pot core assortment?"
23:46:07 <K> pot-core? is that the current trend for hip ppl to listen to?
23:49:21 <electrohead> lmao
23:49:44 * electrohead adds K to a pot of potats
23:50:11 <Agripa3> Could use a different core, but pot cores are self shielding and I have some on hand to test with.
23:50:14 <electrohead> TIL galaxian on the SNES has a fast mode, and only one bit needs to be set in RAM to enable it
23:50:28 <Agripa3> Need a double bobbin for what I have in mind though.
23:53:37 <K> bob-in-a-pot
23:53:44 <K> sounds like something brittish
