ssi2130 8hp module (also done an expansion module to support the vc-mixing on the ssi2130).

Looks great!

Are you hand soldering the QFN?

using your tip correctly is much more important than which iron you use. I use a tip tinner once every few days, use only a brass sponge for tip cleaning (prevents thermal shock and maintains consistent tip temperature). 310-320 C for a leaded 63/37 with R or RA flux. When turning off the iron for m...

Anyone aware of an 0603 veils v11?

Question about plated holes for jacks/pots/etc, jlc’s listed capability for PTH Hole Size is “ Min. drill size is 0.20mm. Max. drill size is 6.30mm”

I’m sure I’ve seen larger plated holes on pcb panels. Does anyone know which fab houses do plated holes large than 6.30mm?

you'll come across TTA branded cables on... AliExpress!

Can you share a link to the aliexpress listing? For the purpose of research of course

Anyone have the part # for the push button that goes to the freeze on Monsoon? Hi japes, take a look at E-Switch LP4OA1PBCTG, where TG means Transparent cap and Green led. As with any part, check the data sheet to make sure this fits your needs, and choose whichever variations on the part number yo...

I made my suggestion at Tayda, they replied "I have forwarded your request to our Product Sourcing Dept, they will try to get the parts as soon as possible". Tayda appears to have these in stock now https://www.taydaelectronics.com/potentiometer-variable-resistors/rotary-potentiometer/linear/100k-o...

Welcome Thomas!

If you can upload a picture of the board top and bottom I’ll take a look. I don't see anything clearly wrong given the image quality. If this were my board, I would compare the board and parts placement against the schematic, and use a DMM to check connectivity of all components around the left inp...

If you can upload a picture of the board top and bottom I’ll take a look. It’s a relatively simple path from input to output. Since it’s heard on the headphones as well, the issue is likely present around the first TL072

I recently assembled a DIY Output module, full kit, and have met a technical issue with the left channel output as it sounds really low(nearly mute) compared with the right channel. This issue appears both with phones left output Which version of Befaco Output? If version 3, check that the input re...

now I need someone to explain what function those edges serve.

As far as I'm aware, their primary use is a surface-mount flavor of board-to-board connection. Manufacturers may choose this over through-hole for a variety of reasons.

I regularly make 2hp PCBs like this without castellation. The plating does tear a little bit sometimes, but the only point of these holes is to secure (and possibly ground) the potentiometer to the panel with which I've never had problems. Thanks pjbulls! This is great to hear. I'd be more worried ...

Figured I’d revive this thread in case it would inspire anyone to show any recent efforts. I’m impressed with the clever ideas implemented by Neutron Sound, the textured ground planes are so good!

I think the first one is fine.

Thanks for your tips Flounderguts.

Hello fellow wigglas, I came across this nice Schmitz ADSR layout by Kraakenstuff and was wondering if a fab house would require castellation in order for the potentiometer mounting holes to be properly plated for a secure mechanical connection, or whether standard PTH is secure enough. Attached are...

I have built both Warps and Rings and neither had a normalization calibration procedure, just v/o calibration. Both have a normalisation calibration, you just didnt do it! Plaits also has a normalisation calibration but you dont need to do it explicitly (the normalisation probe is calibrated when y...

Normalisation procedures can be found in the second tab of the linked sheet

Hi everyone. I'm wondering if anyone knows the Normalization procedure for Plaits. As expected, pin 30 of the stm "normalization probe" sends pseudo white noise to the switch pin of the Trig, Level, Timbre, FM, and Morph jacks. This is supposed to be used by the mcu to detect if a cable is inserted ...

Honestly, I really haven't been able to find much in terms of 3300ppm. Especially since the Panasonic ERA-V thermistors have been declared obsolete. Alternatively, this is a 1K, 3600ppm 0805 PTC. Close enough? KOA Speer LT732ATTD102J3600 Thanks for the link. I do think this will be accurate enough ...

Can anyone recommend a suitably available 0805 PTC 2K (or 1K) 3300ppm thermistor in active production? Cheers!

NLC 2xLFO, a really wonderful circuit (pardon the image rotation)

Anyone aware of retailers planning to sell these in small quantities?

Ideally your magnification will be a two eye thing so you can focus properly.

Excellent, will definitely go this route. And excellent tip using blue tack.

Thanks so much for your help everyone. Feeling much more confident to proceed.

Thank you all for the help. To stay on the economical side with parts I’ll stock up on 0603 (pardon the typo in the title). Also the stripboard compatibility sounds great! As far as using 0603 on 0805 pcb footprints, this sounds appealing for the larger soldering surface. Are there any preferable ma...
