That's fair. Goodness knows many homes don't have the greatest ventilation, unlike our labs. Though the existing toxicological data on heptane aren't very condemning, I do agree with you that limiting exposure is the best strategy. EDIT I should clarify that I don't think that anything you said...

You might be surprised how much better the heptane/IPA mixture works than straight IPA, seeing as fluxes are mostly nonpolar stuff. I've found that straight IPA has a tendency to smear the flux around before removing it, where the heptane/IPA mixture clears it right out - may just be the solder...

This is beautiful, I love the little MOSFET-planet icon. Well done.

That being said, you can still use Zener diodes as regular clipping diodes as long as you have an antiparallel pair; in this arrangement, the Zener voltage doesn't come into effect and they'd look like a pair of regular silicon diodes (in which case there's not much point, just use a pair of...

Nope, that's totally fine, rock it.

Love me a good Muff (👀). Great collection!

Changing oil in vacuum pumps is a shockingly large part of my job, and it seems like I'm nearly the only one of my coworkers that knows how to do it without leaving a mess, so I feel for you.

I mean you can still change it :ROFLMAO:

Yeah those large superconducting solenoids are no joke. We have an instrument in my lab like this as well, there is enough stray field that when the magnet is charged to maximum field (7 T, I don't remember the exact current needed but probably in the 100s of amps) my (quartz) analog watch(es)...

1) is your standard linear "B" taper, 2) is your standard logarithmic or "audio" "A" taper (which is ironic because that curve is not a logarithmic function), 4) is the reverse-log or "C" taper (which is really more like a logarithmic function), 5) is a "W" taper, sort of sigmoidal where you...

Historically I never bothered cleaning boards but recently I started doing so with DIY-ed IPA/heptane cleaner - really works (the heptane helps to better dissolve the more nonpolar flux relative to straight IPA).

Website isn't working for me, returns a "connection reset" error. Nice project though!! EDIT: my bad, it was my fucking antivirus.

The Black Eye is amazing, order one right now.

I'm using a 5751 in mine and I actually find the opposite, I want a bit more gain out of it - it only starts to break up with the gain almost at or at max. AT7 should be totally fine, I have had one in my Space Heater since its birth. You should even be okay with an AY7 even with the higher...

Runoffgroove is doing this in several of their circuits as well. The DC check suggested above is a good idea, but if you're not after the clipping character of the LEDs, I wouldn't recommend moving them. It also might be worth just keeping them in case you want to put a booster or something...

Uh, what? The CA3130 definitely has compensation pins? Slew-rate limiting of the 3130 via compensating capacitors is a cornerstone of Bjorn Juhl's circuits (and several other well-known circuits, I've even designed one that uses this). It's not needed for proper function of the circuit in these...

The Binary is a cool fuzz that will definitely vibe with a Stingray.

Thank you both! Nope, had it drilled also by Spencer. I used to drill all my own enclosures, which was fine when I had easy access to a drill press - now that that's no longer the case, I prefer to have them drilled by the fab house [Tayda/AmplifyFun/whatever] instead, as it eliminates mistakes...

Amazing, great job!

Watching this, seems like a great idea!
