Tindie

Just finished my build and can say it was pretty straight forward and just took a day to build.Will definitely buy again.

Brad | July 6, 2018

Works great

Another fun and easy to build module that worked on the first try. Would buy again without hesitation!

Brad | June 25, 2018

Great product

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!

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!

Perfect addition to any rack.

This is a great little envelope generator and is a perfect addition to any rack. One can never have too many ADSR's. Top notch documentation and a great PCB and panel layout.

Tucker | June 16, 2018

Awesome, compact, DUAL!!!

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.

Tom | June 9, 2018

Stellar!

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!

Callum | June 7, 2018

Great value

Echoing the previous reviews, this is a great, compact ADSR with thorough documentation, easy to source parts and a straight forward build. Will be back for more

Callum | June 7, 2018

Bang for your HP

Once again, lovely stuff. Tracks nicely and great for fitting in extra voices into already crowded rack.

Does what it says on the tin

For Clock Generator (Eurorack PCB Set)

Great little module to lock your system an to get those LEDs blinking. Easy to source components and a great price.

Kane | May 28, 2018

A joy to build

For Clock Divider (Eurorack PCB set)

Apart from the expensive switchcraft jacks used, this entire build is a pleasure.

The only advice Id offer the vendor is that the explanation and BOM around the resistor and capacitor values is quite confusing and I had to read it several times before I was confident.

Response from PMFoundations | May 29, 2018

Thank you for your review. The jacks ARE expensive at Mouser. You can try other sources here: https://octopart.com/search?q=35rapc2av&oq=35rap&start=0. I have considered using other types but have had reports of them getting sloppy over time so I think you will be pleased with the performance of the Switchcrafts over time. Sorry about the confusion with the resistor options. Do you have a better way of wording this that I can incorporate into the documentation? If so, please let me know at admin@personalcircuits.com.

Top shelf

For Fatkeys™ VCF (Eurorack PCB Set)

Sounds great and very affordable. The build doc is very clear and I thought the option for either IC package was a great idea.

Response from PMFoundations | May 7, 2018

Thanks Callum. I am glad you like the filter. Your soldering skills must be top notch to get that SSOP Package in!

Awesome Sounding Filter

This filter is awesome, after seeing some of the demos i was hooked. Now actually having the filter its even better, the resonance has so many sweet spots, and having 3 cvs for the resonance is really handy. I did have a problem with the resonance when i first built, but with the help from John it turned out i had the resonance calibrated improperly. He was a great help and responded very fast, I cant say enough of how satisfied i am with this product and business.

Quinn | April 19, 2018

Great service, great VCO, and easy to build

Title says it all, John has done a great job cant be happier. This was my second module built ever and it booted up no problem and sounded great

Quinn | April 19, 2018

Nice sounding and compact VCA, piece a cake to build.

This was my first module to build and it was pretty much dead simple to build. I definitely recommend this module for first time builders to start, also sweet to have dc and ac input

Quinn | April 19, 2018

Nice Compact ADSR

I bought two of these and were very easy to build, documentation was great too. Very happy the way both of them feel, and its very nice to be able to adjust the length of the sustain via trim pot.

Quinn | April 19, 2018

Awesome range

For Synthola Sequencer (Eurorack PCB Set)

This uVCO is great, you can adjust it to become a LFO or a VCO but honestly works good as both. I bought two of these including alot of modules and the shipping was fast to Canada and came in a nice box.

Quinn | April 19, 2018

Handy Seqeuncer

I bought two of these and had one expanded to 16 steps, and i am very happy i have them in my rack. Its very easy to program and i really enjoy the high low switch. It can be used in many different ways not only for a sequencer. I've used it as an envelope with the glide function and the start stop function. while triggering other things with the gates. I also have to say that the manufacturer was very helpful when troubleshooting it turned out i accidentally put a 390r resistor instead of a 390k lol. I strongly recommend this module to anyone looking for a powerful sequencer.

Jean-Sebastien | April 7, 2018

Fun and easy build

For Clock Divider (Eurorack PCB set)

Every modular user needs a clock divider and this one is perfect for a 3rd or 4th project build. The mouser cart link facilitates part sourcing.

Andreas | March 4, 2018

Great Module

For Synthola Sequencer (Eurorack PCB Set)

Nice sequencer with a lot of features in a small package. Bought another one for future use. Building the thing is easy with basic soldering skills.

Ken | Jan. 31, 2018

Awesome VCO

Built one of these and two of the scaled-down mini VCO version (which I intended to use as LFOs, but they get used for everything!). They are awesome VCOs and track better than some more expensive modules. The sine output, which can be tweaked to give a pretty pure sine wave over much of the range, is a real plus! I'm glad I put sockets in for the 13700 and the 3080 (I don't usually) - I recently came across some old 3080s (the metal can version) so must try one out and see if there is any difference.

Response from PMFoundations | Feb. 1, 2018

It will be interesting. Here's a link to the pinouts http://www.circuitboardchips.com/photo/circuitboardchips/editor/20161123140825_40790.jpg

Ken | Jan. 31, 2018

Great ADSR

Built two of these - nice easy build. Really not much to say other than its a great ADSR - does exactly what you would expect, and even has provision for trimming the CV response so that a pair of these track together.

Ken | Jan. 31, 2018

Great sounding filter

One of the best sounding filters of its type that I have had the pleasure to use, and it makes a pretty good quatdrature VCO too (it even tracks reasonably well!). I initially had some problems debugging a fault that resulted in no output. John sent me the schematics of this and the other modules I have bought from PMf and I was quickly able to trace the fault (a Chinese 27k resistor that was actually 27R!). Great value - I will definitely be building more of John's modules.

Ken | Jan. 31, 2018

Wow!

For Fatkeys™ VCF (Eurorack PCB Set)

Wow! - A 2144 ladder filter that sounds just like a classic Moog filter, but which actually tracks beautifully - amazing. Nothing more to say - I bought 2 of these and am using both all the time to add character to my patches. One minor gripe (but not worth subtracting a star) - I wish the description stated that the adaptor PCB was not needed. I bought 2 adaptors with my 2144s and had them soldered on before the Fatkeys PCBs arrived in the post, only to find that I could have soldered them straight on the board.

EDIT: my mistake, I read the description again when I saved this review: "Board accepts SSOP and DIP16 packages and adapters".

Response from PMFoundations | Feb. 1, 2018

Thanks Ken. In our opinion the customer is never wrong, so if you missed the information about the packages, WE need to make it more prominent. We will change the description as soon as possible.

Jason | Jan. 14, 2018

Great VCA

I really like this VCA. Easy to source and build, sounds good to me and doesn't take much space. I'll probably end up with a few of these.

Jason | Jan. 14, 2018

Great filter

I really like this filter. You can get some really interesting and useful sounds with it. Easy to source parts, easy to build. The only concern is the lack of attenuator on the cv inputs, but it's not a big deal. I think an airtennuator, or a homemade DIY version (like I have) is a good companion for this.

Jez | Dec. 30, 2017

µVCO

For Buffered Attenuator (Eurorack PCB Set)

I first heard of Tindie after a maker friend (Circuitbenders.uk) asked what his customers thought seller sites other than eBAY. I had a quick look through what was on Tindie and stumbled across PMfoundations and thought in for a penny in for a pound. I ordered it as it seemedvery, very reasonably priced and shipping inexpensive - it arrived well packaged and very quickly.

I love the PCB and panel - simple straightforward design - great documentation ,quick and easy to build, dead easy to calibrate - and in use the VCO is great it's turned my Mother 32 into a beast!

I'll definitely be back for more modules soon!

Randy | Dec. 29, 2017

Perfect kit for trying out SMD soldering

This is my second attenuator kit from PMF. I'm using the first as a standard build with the 2Q12 VCF, it's a great companion for the filter. The second will be part of a custom-paneled combination 2Q12 + attenuator for my large rack.

Randy | Dec. 8, 2017

Great VCO

I have several of these (in fact, I have a performance rack that is nearly all PMF stuff) and am very happy with them. Excellent price, great sound, easy to calibrate and linear and expo FM. Lots of functionality in a small footprint.

Randy | Dec. 8, 2017

One of my favourite filters now

The 2Q12 VCF is amazing, one of my favourite filters. Lots of modulation inputs and a thick sound more like a 24db ladder. I even compared it with my Moog clone ladder and it easily held its own. Some people might feel the lack of on-board attenuation for the modulation inputs is a downside but I do not at all. Couple it with an attenuator and you have a perfect combination, and an attenuator you can use for anything else too.

Response from PMFoundations | Dec. 8, 2017

There are many weird and wonderful things you can discover with this filter but the provision of the multiple F and Q control voltage inputs means you should plan on a separate attenuator (at least for your envelope output) if you plan to use it for more conventional music.

Randy | Dec. 8, 2017

Handy VCO with a small footprint

Nice-sounding small VCO. I was going to write "utility VCO" but it's actually more than that. Lots of range, very useful.

Erik | Nov. 9, 2017

Great VCO, excellent value!

I bought two of these 3080 VCOs. Rich sound, tracks well, and with many way to patch it into your system. I built both of them at the same time and the two together took about five hours to build, probably half that time to build one. I think the price for what you get here is a really good value. I messaged the maker at one point with some questions. Quick response and very good customer service!

Kay | July 31, 2017

EXCELLENT

I bought it for the sine output! After a little help from the seller (my fault) that thing tracks nicely (actually a little more accurate than my Intellijel Atlantis)!
BUY IT .. better buy the big version for the features, I didn't have the rackspace!

Morten | June 20, 2017

Top notch!
