    low profile momentary switches NC - source?

    Thanks - yeah that might be the way to go. Didn't think of reedswitchs REED SWITCHES The actuators are a bit pricey and hard to find in the US. Digikey and Mouser have some but $$

    low profile momentary switches NC - source?

    Anyone know a place I can get low profile momentary switches? Only need a ON-(OFF) ie normally CLOSED momentary since it for a BOSS pedal CTRL1 and CTRL2 input. I don't want a "tall" enclosure. The "XWING" types would work switch-wise but Im looking for a little shorter. Something that would...

    Powering pedals with coin cells

    kicking an old thread .... how do you get much time out of coin cells at all? Anything over a few mA will KILL a coin cell in minutes: for example a 2V CR2032 lasts maybe 20-30min at 20mA draw -ts 240mAh rating is only for something like 0.2mA. Most coin cells are designed to be very...

    What amp should I build?

    The 2" makes things easier for sure, and the "depth" can be an issue with the top real estate (~4" would be tight). This pic is NOT mine (there's a guy on reverb that sells them) but this is the Hammond steel box 7x5x2. P-H1441-12X His is "backwards" in my opinion with the power and inputs...

    What amp should I build?

    1590dd would be doable but tight. Theres a guy that sells one based on a Hammond 7x5x2 steel box. I just started a small amp design myself based on champ/princeton 5FA2 with parts I have sitting around. Dont want a whole Champ / Princeton amp - have enough cabs already so its a naked "head"...

    Light Pedal (spring reverb) - kinda cool...

    yeah it's kinda neat - nice to see some (old/new) stuff out there. I love a good fuzz or distortion pedal as much as the next person but geez there's like 4 million of them out there!

    Light Pedal (spring reverb) - kinda cool...

    Interesting - can't be too difficult a circuit. Combination mini reverb tank and some optical sensors etc https://gamechangeraudio.com/shop/light-pedal/ The LIGHT Pedal is the world’s first analog optical spring reverb system that uses infrared optical sensors. This system is used to harvest...

    source for genuine TDA2040 ?

    Thanks!! - didn't know about them. Reliable? I hear it's really hard to get genuine versions of these

    source for genuine TDA2040 ?

    I know not "pedal relate" but there's a lot of experience here and was wondering if you could help a fella out... Have an old Peavey SS amp with a TDA2040 - TDA2040s, from what I hears, are widely counterfeit :( Anyone know of a reliable source for a TDA2040? Cant find it from my normal parts...

    Just ordered the Terrarium, wondering about sourcing parts

    >>Tayda is very good for a whole lot. Is the "post service" (to USA) ie the "cheap" method still ok if you dont need it for a month or so? Or is it a gamble it ever shows up? All the other shipping costs are about $15 which for a big order is ok but for a few parts not worth it.

    diy cable tester?

    Never had a break IN the cable - always the ends etc. Of course I'm not on stage or setting up gigs.

    diy cable tester?

    Anyone diy a cable tester? I've built a ton of guitar cables, RCA cables - it's always a PITA holding the cable and multi-meter leads to check out my wiring. So I had some time and parts sitting around and came up with this. Im sure Mr PedalPCB could come up with a vastly better pcb (hint...

    Which soldering iron do you like?

    https://www.metcal.com/soldering-station/how-smartheat-technology-works-a-tutorial/ I just know it heats super fast - maintains temp and is very "light" in terms of the handpiece SmartHeat® heaters® heaters consist of two basic elements; a high-frequency alternating current (AC) power supply...

    Pedalboard acting strange

    That may be significant. (I would highly doubt the 'mains' 120VAC as an issue). Unless you know what the power supplies do under load (power curve)- the "knock off" may be dropping off in voltage with the current draw. I just ran an experiment on some power supplies and bricks - the "Voltage"...

    Pedalboard Power Supplies Voltage Range

    So I've been messing around with measuring dedicated power supplies for various pedals I have, and with some multi-outlet "pedalboard power supplies" (bricks) and have some question about what "range" of voltage supply would be acceptable. This all assumes current supply is adequate etc. Now...

    Guitar Build Wood Screw Disaster... Help?

    there are a lot of small screw extractors (not sure what size you have) - they require a steady hand but do work. This one is more but supposedly made in USA so may be a bit better - cheaper ones may work too extractor cheaper one

    First Oscilloscope Recommendations

    I have the older original AD for my "home" use. I of course had to (in the spirit of pedal building) made a "case" for it out of an old LabView SCSI breakout box

    First Oscilloscope Recommendations

    100% agree. Any of the Analog Discovery - would work great. Two waveform generators, 2 channels isolated input scopes, digital - can measure noise, impedance, even frequency response sweeps. Super capable. python scripting, or in-app java scripting of the software. Check out the waveforms...

    Converting 9V DC to 9V AC

    I think the L5 is +/-15VDC right? you would probably not want to go 9VDC -- 9 VAC -- (+/-15VDC) something like this just go from the 9VDC to (+/-15 VDC) Not sure if the mA is enough https://www.aliexpress.us/item/2251832630848518.html?gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US
