fantastic little clock module
For Clock Generator (Eurorack PCB Set)
This works great with the other pm foundations module: clock divider
to provide some nice binary counting triggers. its frequency range is great considering if you use the divider you have a lot of options.
easy to build and even made a little timelapse of assembly, which took about 45 minutes. https://youtu.be/utXynEoY13k

A year later - SUCCESS!
For Attenuverter (Eurorack PCB Set)
What better time to tackle the SMD demon than right now - a whole year later! After a year or so of through-hole, I've finally decided to hit the SMD projects I've been sitting on, and this was my first!
I blew the chip out the first time through because I didn't see the correct marking. I pulled the chip off and put a back-up the right way-round and now I've got a great 4-channel Attenuverter, AND a complete SMD build!

Thanks Benjamin. As you will now have experienced: SMD op-amps don't just burn out, the chip actually explodes out of the package! It's all very dramatic but at least you know when you have burned a chip out.

Solid, compact VCO.
For 3080 VCO (Eurorack PCB Set)
I actually got this to use as an audio rate modulation source in a small system geared toward processing external signals, but it sounds nice enough I've been using it mostly as a sound source so far. Controls are pretty tightly packed (no surprise for the size) but since they're knurled split shaft it's easy to use them with no knobs if you want a bit more space, and I'd always take proper Alps-style 9mm pots like these over the little plastic trimmers most compact modules use. Easy build but a little fussy to calibrate - even with the multi-turn trimmers the scaling adjustment is really sensitive.
Will definitely be getting a lot of use out of it and would recommend it to anyone looking to add an oscillator that doesn't take up a ton of space and is a bit more feature rich than most compact oscillators.

Sweet Filter
For 3080 VCF (Eurorack PCB Set)
This was my first "front panel and PCB only" type eurorack purchase. Build was really easy. I bought the Mouser cart that was all setup in the documentation and that was all I needed. The filter is awesome. 10/10. Would buy again.

Great little VCO
For 3080 VCO (Eurorack PCB Set)
What a great sweet sounding little VCO, I used the 3080 reissue chips from Modular Addict and it sounds lovely! I bought 3 to make chords using the Ornament and Crime Harrington 1200, sounds awesome. I got the wooden panels which I sanded and oiled and they look sexy. Notes on the build; very easy build, it's stable after an initial warm up period, you must let it warm up for 10 mins at least, not terribly accurate over several octaves but also not too bad, still very useable with lots of smooth character, pairs really nicely with the Kassutronics Transistor ladder filter, the Sine wave is lovely. One thing to note is the right angled power header makes this module just too deep for my case with the ribbon cable attached so swap out the right angle header for a straight one. Don't just make one make 2 or 3, the hp is small, then you can create complex fat chords. Highly recommended. John is a nice guy too, sent me a free wood panel to match my set.

Immediately useful - glad I got two!
For State Machine (Eurorack PCB Set)
This came together relatively easily - looks like a lot, and it kinda is, but the board is laid out well and the parts list isn't too complicated. Having two of these State Machine modules is a great idea - had a whole lot of new and interesting motion in the chaos, and already finding different things to both throw this at and throw into it - thanks again!

Amazing little VCO
For 3080 VCO (Eurorack PCB Set)
This was my first DIY Eurorack module and overall it was a really fun build. Sourcing the parts was easy because of the provided mouser carts and the build guide had all the information I needed. Love the square wave sound and the PWM and FM inputs give it a lot of flexibility. Might get another to detune and add some depth. Definitely recommend.

Amazing Filter Module
For 2Q12 VCF (Eurorack PCB Set)
I got this to get some nice high-Q sweeps, which this does so well.
It was so easy to follow his instructions, and build this from PCB up.
He is also very quick to answer any questions I had.

You can never have enough LFO
This not only has an LFO with 2^3 = 6 modes, but it can mix in noise, sample and hold and all around provides great utility to any eurorack setup.

Midi Host control with CV + Gate
For 8 Voice MIDI-USB Controller (Eurorack PCB Set)
This polyphonic midi-usb controller works well, even with an "unlisted" midi keyboard.
This reads the commands from the midi keyboard and translates it to cv and gate outputs, it has a few modes and some other fun behind the scenes things that can be accessed by midi-keyboard commands.
Works well and was fun to build.

Great VCO!
For 3080 VCO (Eurorack PCB Set)
After a long time I finally got this project completed, I had trouble to get one of the needed components in Sweden but the seller was helpful and sent me what I needed together with a new order. The build is well documented and the VCO tracks well and is easy to calibrate and set up! It also sounds great!

awesome eurorack module
For Clock Divider (Eurorack PCB set)
This module does exactly what it says, divides a clock signal into binary increments. The instructions online are top notch, as well as having mouser carts for the components needed to build one.
I've bought a few modules from him and they are all similarly easy to assemble if you follow his directions.

Very cool module
Combination of modulation, sample and hold and noise in one module. Multiple modulation waveforms, ability to change the width on the pulse wave and a button to take it up to audio levels so you can use it for audio-rate FM too. Also has multiple simultaneous outs. I have two of these, one for my portable rack and one for my big rack.
Randy | Nov. 4, 2019
Easy and quick build, great intro to SMD soldering.
Built two of these, gives me four slew generators. It's a combination of through-hole and surface mount parts so it's a great practice module. SMD is not as difficult as people seem to think, and I use a standard soldering station and have no issues, even with the IC.

Amazing VCO
For 3080 VCO (Eurorack PCB Set)
I've been playing this as my main square wave voice for 1 year now, I just have to say after that much time it STILL draws me back in to use it! The build process is also fun, with a lot of parts but not a super difficult build. The pwm control is GREAT. I recently started using it with a 3 channel mixer module to mix the three waveforms together which yields excellent sounding subtle results! Also one great feature is that the warm up time for stable tuning is practically zero. Nice work!

An outstanding envelope generator with full CV over adsr
For State Machine (Eurorack PCB Set)
TLDR: Pcb and panel kits for eurorack EGs that have cv control over each segment of the envelope are surprisingly hard to find. Other manufacturers’ designs either don’t provide a full 4 stage envelope, or use expensive and hard to source slider pots. Not only was this a fun build, but it’s a very useful and usable module, and it looks cool too 😎
I made a pledge to myself about six months ago when my modular obsession started to get a bit out of hand: no more pre-built modules. I would only build, and as I built I would replace the functionality of my pre-builts and sell those pieces off. The one type of module that has long stymied me in this is the cv controlled envelope generator.
Having this kind of control allows you to use any voltage source to inject semi-random or evolving elements into a patch. It’s highly useful for designing pads and ambient effects. It’s probably some of the best fun you can have with a synth.
The gates per segment are very useful for, say, building out larger structures in a patch, or as an erratic clock. You can use them to trigger other envelopes or to trigger the module itself. Or both.
The loop function provides a more usable wave than some of the other EGs with the same function I’ve built, part of which is down to the shape of the attack portion of the envelope as it plays out over the turn of the pot, but part of it is how fast this will oscillate. Sequencing different envelope segment CV ins while feeding a VCO 1v/o from this module looping very fast provides some very interesting blips and bloops indeed. Like I said: a lot of fun is possible here.
One thing I have to caution about: definitely read the build guide closely and keep it handy when you build. This project has some tricky assembly order stuff with the jacks and the plastic latching switches that can get you into some trouble if you stuff the board in the wrong order, like I did. I have a steady hand and some nice fine iron tips so I got everything in without melting any switches, but it could very easily have gone wrong.
Also I have to mention the panel, it’s this rich red pcb. I actually like pcb panels, some people don’t, I do. The pictures don’t really do it justice. Honestly I love this module and this designer, and I’m looking forward to putting together more of his stuff.

Thank you for your kind words Dmitri. I designed this module to be almost as good as you describe it. I can't thank you enough for experimenting with the module and I think you may have a second career as a writer!

Nice vintage-style EG
For ADSR-D Envelope Generator (Eurorack PCB Set)
This is an easy-to-build envelope generator for people who are looking to duplicate the functionality of vintage synths such as an Oberheim SEM or MiniMoog. It can act as a 3-stage EG, as those two synths have, or a 4-stage. It's a great part of a vintage-sounding Eurorack setup. Combine this with a pair of 8080 VCOs and a 3080 VCF and you're on your way to coming very close to the sound of an SEM.

Tribute to a classic and another great VCO
For 8080 VCO (Eurorack PCB Set)
Compact VCO but not too compact, controls are comfortably-spaced. Nice set of features, great sync and, hopefully I can mention this, a tribute to the VCOs on the classic Oberheim SEM.
Response from PM Foundations | April 23, 2019
Well, who do we have to thank for the comfortably spaced controls?

Very interesting envelope / function generator
For State Machine (Eurorack PCB Set)
This is a really interesting module, capable of complex envelopes and cool interactions with other modules. It can act as a regular 4 stage EG, with linear or exponential responses, it can change the state of its stages based on CV inputs, it can loop and act as an modulation generator, it can trigger other actions at multiple times and in multiple ways, and it can even act as a percussion trigger generator.
I have this one sitting with my function generators and modulation generators instead of with my envelope generators.

Great vintage-based VCF
For 3080 VCF (Eurorack PCB Set)
Very nice multi-response filter based on a vintage module that has the initials S.E.M. designed by someone with the initials T.O. This one can be built to respond like the original, without self-resonance, or a bit more modern with self-resonance. Either way, great-sounding and a good addition to any rack. I have two so far, and another on the way.
I have 22 modules currently in my racks from PMF, with a few still on the bench and more on the way. So I'm happy with their modules.

Love the sync on this one
For 6080 VCO (Eurorack PCB Set)
Very nice VCO, particularly like the sync, some great sounds available. I look at this one as a souped-up 3080 (I have 3 3080s in various racks).
Response from PM Foundations | April 23, 2019
Judging by that video, it looks like you know how to play it too!
Randy | April 23, 2019
Great envelope generator
This one is very handy, a classic 4-stage EG but with the addition of voltage control over the stages, gate or trigger inputs and linear or exponential response. Definitely worth having one or two in the rack.

A quick and easy mixer
For My Little Mixer (Eurorack PCB Set)
Worked first time I plugged it in. The build only took a leisurely two hours. I just use a small, long nose soldering iron and tweezers to solder the SMD parts. Very easy and works like a champ. I built the version without front panel switches and just use the pins with pc jumpers to change between DC/AC signals.
Vidar | Dec. 20, 2018
Had this for a year now and I still love it.
For 3080 VCO (Eurorack PCB Set)
This was my first eurorack module and the first time I soldered anything else than guitar leads. Got it working on the first try and been building modules since. The soldering I did is probably pretty crappy and and the panel would be easier to mount if I knew what i was doing, but it was FUN. Got a ca3080 reissue six months ago and it sounded even better. It'll always be my favourite modul. Would really recommend using T18 potentiometers if you are sourcing your own parts, since the micro knobs from thonk (Befaco style) are kinda mandatory if you are suffering from sausage fingers like I do. Would also skip the right angled 16-pin header and use a straight one, might not be ideal since it'll be a little wider, but I doubt it will ever come down to the few extra millimeters the straight header adds. I use Tip Top Z-Ears and this module is just slightly too deep with right angled headers. It would make contact with the surface, alway applying little bit of pressure before I changed it.

Takk Vidar for din anmeldelse og for å gi kundene noen nyttige tips. 3080-VCO er ikke den grunne av moduler, men er definitivt ikke en HP hog.
(Thank you Vidar for your review and for providing customers with some useful tips. The 3080-VCO is not the shallowest of modules but is definitely not an HP hog.)

Cool, inexpensive, handy
For Toggle (PCB Set)
This is quite a cool little module. Easy build, inexpensive and works great. Had lots of fun clocking it with a function generator instead of a regular clock or LFO.

Great, easy to build oscillator!
For 3080 VCO (Eurorack PCB Set)
Just finished my build and can say it was pretty straight forward and just took a day to build.Will definitely buy again.

Great product
For Dual VCA (Eurorack PCB Set)
This Dual VCA was a fun build with easy to follow instructions. It worked great with no problems. If I was building a bigger eurorack, I wouldn't hesitate to buy and build another one of these modules.

Great space saver VCO!
For Micro VCO/LFO (Eurorack PCB Set)
This little VCO is awesome! It barely takes up any space in my rack, and tracks wonderfully. At first I had issues with tracking, and after e-mailing for support (which resulted in near instant response with help) I realized it was probably hardware related. Turns out the mystery origin 2n3906's were at fault. I matched up a set from a known good supplier, swapped them in and the tracking is wonderful. I can't wait to build some more modules from PMF!
Tucker | June 16, 2018
Awesome, compact, DUAL!!!
For Dual VCA (Eurorack PCB Set)
This VCA, as all modules from PMFoundations, is of incredible use, and comes in such a tiny package! Great PCB and panel layout and excellent build documentation. I will definitely be doing business with PMFoundations again in the future.

Stellar!
For ADSR Envelope Shaper (Eurorack PCB Set)
When it comes to simple DIY modules, these are simply the best. The design is easy and compact and works without any strange behavior. Perfect for someone just starting to build from PCBs and not just full kits. Arrived in only 2 days as well! Thanks!
