Got the boards in the mail today, they're really nice quality. It took about a month to get to the US from Spain, not bad considering the state of the world right now. I'm looking forward to putting everything together!
Great little dual function generator, a must-have for any Eurorack system, regardless of if it's lacking a Maths/Rampage or not! Great seller too, helped out a ton with messed up shipping situation in my country. Easy, well-documented build.
Due to my lack of Arduino knowledge I could not get it too work, I contacted the seller and he kindly explained what I was to do. He was very helpful. Now I get to play this amazing little synth. I think I may in time incorporate this into a toddler friendly toy for my kids. Great fun, with +1000s of sounds.
I bought the assembled version so I cannot speak to the building of the kit, but the synth itself is fantastic. I've got quite a variety of inexpensive "noise toys" and this is one of, if not the, absolute best. The variety of sounds available, and the range of "quality" (from crystal clean to glitchy, gritty dirt) is phenomenal. Comparing it to the Korg NTS-1 and the Bastl Microgranny I would put it nearly equal to the NTS-1 (only because the programmability puts the Korg in a class of its own) but well above the Microgranny because of the ease of getting such a wide range of usable sounds so easily.
If you're looking for glitch you absolutely need this, in the first 3 minutes I was able to getting slowly evolving drones, melodic leads and almost percussive bass lines--and that was just trying to find out what the buttons and knobs did. Just playing around with it is well worth the money, but running it through FX pedals, a DAW or a modular/semi-modular system will make worth 10 times the price.
My only complaint is the lack of an option for tracked shipping. It was shipped within less than 24 hours, but between being unable to add tracking and the current world-wide shipping delays, I was starting to get worried I wouldn't see it. It was well worth the wait. If you are curious enough to be reading the reviews, you owe it to yourself to buy it.
Lovely kit! The PCB is beautiful and high quality, it makes very clear which parts you need to put where. Assembly is straightforward and easy - it makes you feel like a soldering pro even if you aren't one.
It's fun to play with it once assembled, very relaxing to experiment with positions of the knobs and hear the response. You can connect it to an amplifier or use headphones directly.
Another awesome aspect of the kit is that you can replace the formulas used to generate melodies with some other ones if you want - it's Arduino based, so all the tools are available and free.
The idea of this kit has a lot of potential: - knobs could be replaced with a gyroscope or accelerometer(s) - an OLED display and buttons could be added so that we could have more formulas and an easy way to select them - a MicroSD card could be added to store parameters and perhaps even whole tunes Most of this you can pretty easily do yourself if you get bored with the Glitch Storm as it is!
Firstly, I'd like to say that this sonic gizmo includes no documentation at all. (Even a single-page how-to would've helped.) However, if you've soldered any other projects before, it'll be fairly obvious what goes where and how (meaning, which holes are POS and which are NEG and which don't matter). The only not-obvious connection was the sleeve (GRD) for the 3.5mm out. After consulting the online photos, I rolled the proverbial dice and bent a stiff wire to fit from the hole to the appropriate prong and was up and running in little time at all. Lucky guess maybe. Oh, be mindful to bridge the indicated contacts on the underside of the PCB! Not sure what'll happen if you don't, but best to be on the look-out going into this project.
That out of the way, this little guy SCREAMS! So many sounds can be pulled from just the few knobs provided. I've barely scratched the surface I'm sure--having only just completed the build--but it is indeed VERY glitchy, but surprisingly "musical" and at times also very rhythmic. Can't wait to dive into it more!
tl;dr: Great sounding device! Would benefit from a simple guide. So long as it's not your first project, you should be fine though.

Loving your review, Robert... I agree with all, except that in the github page there´s the BOM listed, so it has all the info you need to build this evil machine :D. Anyway maybe I should just print it and include in the packaging... nice suggestion.
There´s also a thread in Muffwliggers with some hackings explained the expand even more the machine possibilities.
This is a perfect beginner kit for those into electronic music, sound design, or video game sounds. I have only played around with it for an hour, but there are so many usable sounds that can be coaxed out of this device. I am a relatively inexperienced solderer and it took me around an hour to build. The most tedious part is soldering the header pins on the arduino itself. Everything else on the pcb itself is very well laid out with plenty of space. Quite a musical machine despite being "glitchy. " As a bonus the pots came with knobs so you don't have to fuss with the mini-pot stems. It has a mono signal (I think), but a stereo audio jack which makes it useful for playing through headphones or computer speakers. Overall a great kit!
I really love designers who pack a ton of function into these Arduino platforms and then mount it on a neatly-designed, simple through-hole package made of fairly easy to find parts! This came together pretty quickly and I was immediately getting some fun new shapes out of my sound that I hadn't had before - thanks!
This little project is easy to build, and it makes very cool sounds. I modded the code a bit with excellent help by the creator and gave it an extra potmeter for pitch. Hopefully I can come up with some alternative viznut equations and get those added to the code.
