Yes and yes.

The answer is, as always, "it depends." If you're using a reasonable power supply, an extra handful of microamps of leakage are not going to bother your Cioks DC7 that's capable of supplying 660mA to a <50mA load like a Klon. This will matter a bit more if you're using a battery, as leakage...

My opinion is that you absolutely can drop them in for any and every electrolytic cap on a schematic if you have them on hand. I would say if the original design has an electro in the signal path (typically a no-no) these would be a good alternative if you don't want to use tantalum. They're...

We're talking about different things here. Electrical leakage refers to leakage current, not physical leaking of chemicals. Granted prolonged electrical failure of a capacitor can lead to physical failure which can result in chemical leakage, but "low leakage" doesn't mean "less likely to spill...

I think the chances you'll hear a difference between a regular electrolytic and a polymer electrolytic are slim. I've see a few IC datasheets that specifically call for them when high capacitance/high voltage/low ESR/low leakage are required, but that describes a miniscule amount of what happens...

I'm a strong Arduino advocate, that thing rocks. Very easy point of entry into embedded systems and provides a great balance between simplicity and capability. The interface is easy enough to use that you can learn to write a simple program in under an hour, and in college I wrote a real-time...

The tricky thing about turning Wrecking Ball into a two-channel preamp is you almost definitely need to go to 1590DD, there's no way you would be able to fit two footswitches and 10 pots (I figured drop the presence control) with three tubes in a 1590XX. If I were to do a two-channel, it would...

Everything sounds completely possible, but you're describing a big complicated multi-channel thing with independent EQ per channel and then saying That's always the trade-off. A two-channel preamp is feasible in a 1590XX, but if you want to add a bunch of features you're going to be moving into...

The output of Particle Accelerator is hot but in the grand scheme of things it's a high-impedance (38k or so) output so it won't be frying anything, but you will need to keep the volume of PA down so you aren't clipping the input of the next pedal in the chain, because as I'm sure you know, PA...

The ink definitely has a smell, but it's certainly not as strong as lasered paint. The E1 has an air filter to help with the odor, and it's definitely not as bad as my old A4 printer smell.

The only Sushi pedal that does that is Grand Slampegg (unless you're looking at OLD designs), which uses a 6SL7 tube and can't run the heaters in series. You're more than welcome to use a 12VDC supply instead of 9V, which will have the exact same effect, but I find that 9V is good enough to get...

Finally got around to another weird thing I had been wanting to do: UV printed soldermask and silkscreen on a milled PCB. It's not perfect, but it's certainly usable.

Pretty sure it's still on preorder for retail sales, there are still Kickstarter backers that haven't gotten their printer yet. One week isn't really enough to gauge how much goes into cleaning, but so far the prints I've done have been pretty low ink because I haven't been messing with...

Alright, I promised I would give some more info on this when I had more time to play with it, so I guess now is the time to do that. I backed this thing on Kickstarter almost a year ago now, and I've had the printer for a couple weeks, and I guess I've had the ink for one week. One of the main...

Another important sticking point with USB-PD: have you ever soldered a USB-C port onto a board before? That is not a DIY-friendly endeavor. Through-hole versions exist, but they're still not a task for the faint of heart.

Yeah if I were to build a DIY power supply I would probably start with an IEC AC input (most people have USB-PD supplies lying around, but EVERYEONE has IEC cables lying around) and use a small AC-DC converter. No power transformer/rectifier needed, and something like this would spit out a nice...

This is an immediate turn-off for me. USB-C is more reliable than micro-USB, but I've still seen too many broken USB-C connectors, and in something that's going to be plugged and unplugged frequently and attached to something I'm going to be stepping on regularly, I wouldn't trust it for...

Yup, that was also my post lol The chinese manufacturers I've been working with have always provided excellent quality in a shorter amount of time and provided excellent customer service as well.

I mean they could very well just be this incompetent, but I could equally see a case for it being malicious greed to line the pockets of few at the expense of many.

Chinese aluminum has a 100% tariff, but it's still cheaper than getting parts machined in the US.
