I uploaded most of the bill of materials to the website. These are also on GitHub but no need to download the full repository’s if you don’t want to. If you are looking for one of the modules bill of materials you can find them here after the read more

I didn’t have any sample and hold module in my rack. At first I didn’t think I needed one. But seeing a few video’s of what you could do with them I just wanted to have one. A sample and hold basically takes a voltage and when triggered it send the voltages to the output and keeps it at that level until next trigger,in theory. But being in a analog realm the capacitors used to keep the level at the output steady lose there voltage slowly and the voltage keeps dropping. This can be overcome making a digital sample and hold or just to use a quantizer and hope the next trigger will come before the next note is quantized. In practice the last option fits most purposes. So I decided to build a analog sample and hold.

I was looking for more effect units in my rack. As I’m a big fan of DIY there aren’t that much choices. Lucky I found the kxmx bluemchen. A small module, open source and with a Daisy on the back. I did not know about Daisy and it took me on a journey. Oh I went into a rabbit hole last few weeks.

The website where you can find it advertise it as ” the go-to DSP solution for your next audio project.” I looks a bit like a Teensy or Arduino Nano. It took my interest. I soon found out it can do a lot more then your average Arduino. Daisy is made for working with audio it’s a digital signal processor (DSP). Meaning it can do a lot of things with audio signals. It can even be the source of a audio signal. They also sell T-shirt with the slogan “We make computers sing”. It took me awhile before all of Daisy landed in my head. But now I’m a big fan of this little micro processor.

Oh boy oh boy. This one is very special to me. I was in a bad period in my life when I started reading the Noise Generator Cookbook by Thomas Henry. Reading it gave me a lot of rest and I learned a lot from it. I didn’t know that much about noise, white, pink, red, blue and the noise in my head, it all started clearing up. In this book Thomas Henry writes about the Mega Percussion Synth (MPS). Back in those days a lot of schematics where based upon 15volt. I always wanted to have a MPS but never found the time and skill to transfer his design to eurorack (12 volts)

Then Haraldswerk released the MPS, and put the gerbers online for building one. Sadly it was still 15 volts and with banana jack. Not typical for eurorack. I wrote about this in the topic Haraldswerk posted on modwiggler. And I wasn’t the only one hoping for a 12 volt version with 3,5 jacks. That started a discussion and.. well

I found a way to remove all those post about the modules in my rack from the frontpage. I think I have most of them written now. I might need to update a few of them while playing with the modules more and more. I thought the frontpage got a bit messy with all those post so glad to found a way of removing them. Next up all the panel files I made and adding them to the website. After that maybe record some sound samples. Maintaining a website does take some time but I still enjoy doing it.

I have a love and hate relation with Erica Synths DIY modules. Some are quite nice to build but most of them are just terrible to build. I makes me wonder why Erica has left the DIY scene. I’m glad the put the designs on GitHub for the modules that they call legacy DIY. But I think the support desk was just overloaded cause these modules are just a pain in the butt to solder and are prone to make mistakes on. I had the VCO in my drawers for awhile and it was time to build it.

I have been posting different modules to this site and give a little bit of information on them. These modules are all in my rack and for the menu item “My Rack” I need them as separate posts. I tend to add more in the upcoming weeks as there is more in my rack ;). I might list a few as open for offers/sale. So if you looking for some DIY modules that can’t be bought as build modules and have seen them in my rack. Send me a email or thru the contact page if you want to buy any of the modules listed as open for offers.

If you want more information on them please let me know in the comments.

Small update: When writing a few post on haraldwerks modules I noticed I never put up all panel files. So more stuff to do adding panel files for some of these modules.
