Fantastic
For State Machine (Eurorack PCB Set)
I had some problems and the seller worked through them with me over the span of a few days, helping me to troubleshoot and ultimately fix the problems and get the State Machine running! I can't recommend the module or the company enough!

Cool sequencer well featured pack!!!
For Synthola Sequencer (Eurorack PCB Set)
I bought 2 of this modules as a DIY kit a few weeks ago as a special package, the deliver was quick and communication with the seller was great!!
Now the build is quite straight up and the documentation is good and help on every stage of the setup, now the build itself can be quite challenging specially when your mounting knobs buttons jacks and Leds cause there is a few components located in some really tight spaces but nothing but nothing impossible to achieve.
Now the sequencer itself it is well implemented in terms of controls, play modes and is a breeze to operate, sequences go quite stable, and it is pretty cool and straight forward (as a suggestion play a melody with one sequencer and use a second for modulation and god damn you have techno for days!!!)
So go ahead and get a pair of this modules they work as a charm!!!!

I really enjoyed getting this kit together for you Octavio. Thank you for your feedback and good luck with your music making. I also really appreciate the international mail services that got it to you reasonably quickly, it's not a stone's throw.

Great oscillator for a massive sound
For 8080 VCO (Eurorack PCB Set)
Stacked 2 of these on top and it sounds great. First tuning after building can be a little slow but after that, the payoff is great. Definitely recommend getting one or more of this oscillators.
Response from PM Foundations | July 2, 2021
Thanks Ralphy. I really do appreciate your patience with the tuning and for your feedback on the VCO.

Instant Fat!
A great sounding module. It makes a single oscillator sound like many. The build is straightforward, there are no exotic parts, and even though the (clear and well-written) documentation specifies that an oscilloscope is required for calibration, I was able to get pleasing results by ear. As Duke Ellington said, "If it sounds good, it is good." And it sounds very good.

A nice little VCO/LFO combo!
For Micro VCO/LFO (Eurorack PCB Set)
Nice kit for a simple VCO/LFO! The documentation is very good and the PCB clearly labeled. I like the layout of the panel a lot.
Bret | May 5, 2021
Excellent seller. Great communication. Very fast shipping
For Dual VCA (Eurorack PCB Set)
Everything as described. Documentation was great, making the build super easy. All appears to be working beautifully. Already a repeat buyer

Excellent seller. Great communication. Very fast shipping
For 3320-VCF (Eurorack PCB Set)
Excellent seller. Have built a few each of seller's Toggle and Dual VCA... still have to build Attenv and vcf. Looking forward to those builds as well.

Excellent pcb/faceplate kit
For Toggle (PCB Set)
Note: The panel appears purple in the picture listed. While I wasnt picky about it, I am glad I received a black one. I'd imagine you can ask the seller to confirm the color if you need. I finished this kit the other day and it has been working flawlessly. The seller was quick to respond to provide links to parts that can be used to substitute the parts that were out of stock. Greatly appreciated! Will do business again. Thanks
Response from PM Foundations | April 15, 2021
Thank you for your feedback and review. I have duly updated the description to include a note about panel colors. The BOM has also been updated after your inquiry. Thank you for bringing these things to my attention.

good experience
This slew module was the first Eurorack DIY project of mine that required soldering SMD components. I was a little intimidated tbh, but the detailed instructions were easy to follow and I did my best to solder the SMD components with a fine tip soldering iron. However, when I powered on the module, it did not function as expected. John from PM foundations was extremely communicative and helpful in troubleshooting the module over email, and with his help, we determined that I had managed to incorrectly solder a few of the components (including one of the ICs). As SMD ICs are difficult to replace, and I don't have much experience in replacing them, John offered to fix the module and send it back to me. I sent the module to him and received it back in perfect working order about 1 week later. Can't thank him enough. The support John provides re: PM foundations modules is top-notch, and he goes the extra mile to help work through issues and ensure your DIY build is a success. I bought more PMF modules because of the good experience.

State Machine - A+ Product
For State Machine (Eurorack PCB Set)
Not your average envelope! Use as an ADSR EG or Wavetable LFO, and send outgoing gate signals at the onset and end of each envelope stage. Slick design and enjoyable DIY build. With only a few eurorack DIY kit projects under my belt to date, this project was perfect for my experience level. Well documented - with detailed instructions, pictures, and contextual information. The documentation contains a link for a Mouser shopping cart, which I really appreciate and highly recommend using - it greatly simplifies sourcing components for the build. When I purchased components, some of the items in the Mouser shopping cart were out of stock, but there are typically lots of options within Mouser for each type of component (some in stock and some out of stock), so I used the search function on Mouser to find analogous parts that were in stock and available. A big thanks to John and PM Foundations for a great product. One of my favorite modules in a small but growing system.
Response from PM Foundations | Jan. 8, 2021
Thank you for your kind words Simon. I'm really glad you enjoyed the build and the finished product.

Classic CEM Sound In Eurorack
For 3320-VCF (Eurorack PCB Set)
An easy, straightforward build (worked perfectly on the first try!).It sounds fantastic, the same smooth, round tone you'd expect from a classic Pro-One, with the added bonus of voltage controlled resonance. It's already a mainstay in my Eurorack setup. I'm hoping it gets some company from other CEM based designs, like oscillators and envelope generators.
Don't hesitate, buy it!

Easy build
For Dual VCA (Eurorack PCB Set)
Fun and easy build! I have 3 PM foundations modules I built from kits and they all worked first try. Fast shipping too

Great first SMD project
For Attenuverter (Eurorack PCB Set)
This was my first crack at an SMD project and it was a very easy build considering. All documentation and build instructions are clear. Module works great!

Easy build, handy utility
For Buffered Multiple (Eurorack PCB Set)
This is an easy build and a good utility to have. I just built four of them, one for the main rack, one for the secondary rack, actually to help me interface some old ARP synthesizers, and a couple of spares that I'll use when I free up a bit more space. Also a great intro to SMD.

Great piece of kit
For ADSR Envelope Shaper (Eurorack PCB Set)
I ran into an issue building this and Mr. PM was able to diagnose it quickly. (I also discovered I have 6.8k resistors in my 68k drawer!)
Overall a great module, low part count, and easy to build. I bought 3 for all my envelope shaping needs!

Good starter module
For 3080 VCO (Eurorack PCB Set)
After much online research, I decided on the 3080 VCO as my starter oscillator for getting into Eurorack and building my first modular system.
I really liked the simple layout and look of the kit. However, I took it one step further and sourced the majority of parts myself. This ended up saving me a bit of money rather than just going with the suggested BOM by PMFoundations, but I would caution those who are starting from scratch that this is a complicated task and if you are not familiar with electronics and parts and such, you can easily order the wrong version of components and end up spending even *more* money when you have to purchase the correct (assigned) parts.
The assembly instructions are straightforward, but again this DIY kit implies that you have the necessary equipment needed to build/test/tune the module yourself. That being said, I had a good time putting together the parts, soldering everything together and got the thrill of hooking it up for the first time and getting sound!
This VCO is well rounded, having a basic Sine, Triangle and Square wave output. This makes it well suited for a variety of roles, from an LFO timer, to a modulation signal, to just a pure tonal generator. I am still exploring all that this VCO can do.
I ordered a pair of these kits (PCB and face plate only), and with all the assembly and testing, I'd say it took me about 5 hours per module.
I have since installed them in my rack, and enjoy using them as the foundational tonal source for experimenting.
These kits have sparked more interest in other functional modules and I've begun working on my own builds to add to the VCOs.
Thanks, PMFoundations for making a solid VCO anyone would be happy to include in their modular system!

Versatile value
For Dual VCA (Eurorack PCB Set)
I got the PCB and face plate kit, and ended up ordering the components myself. This was a nice intro to DIY Eurorack.
I like the layout, and this module packs a lot of value at having two VCAs for the price of one. The assembly was straightforward, although the DIY kit implies that you already have the equipment needed to solder/test/calibrate your module. I would not advise this unless you already have some basic electronics skills.
The VCA is easy to use and is versatile in function. It goes well with the other modules I've put together from PMFoundations.

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!

Response from PM Foundations | April 9, 2020
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.
Jeff | Jan. 14, 2020
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-CV Converter (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.

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.

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 / Sub-Oscillator (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!
