Kickstarter Project at 75%

Cheers to you Kickstarter. The project reach 75% funding in only two and a half weeks.

I’ve been through every emotion imaginable. It’s really exciting to reach this point in the project. The response is a validation of the work I’ve done for the past year and a half pretty. I’ve overcome problems which I couldn’t easily resolve after days and weeks of scouring the internet and reading dense textbooks.  I had to learn a lot about digital signal processing, firware optimization, filter design, and about how to use all the parts I ended up using. The good part for you is that I’ve learned about all this stuff, packaged it into the synth, and written about and will continue to write about it on this blog.

Through the excitement, I’ve also had moments of sheer sweaty panic. Watching the backers roll in gives me a sense of obligation to deliver the best possible design that I can. So, I’ve continued working on it. I’ve been tuning the hardware to maximize the signal to noise ratio and may make on last hardware change to substantially reduce noise. I’m working on expanding the sonic offerings by working on the wavetables and their playback. I’ve found bugs in the filter envelope and fine tuned the timing of the filter envelope and the adsr envelope. I’ve still got some work to do.  I’m still working on the case. I’ve got to make a CAD drawing of the location of the holes in the front of the unit along with the silkscreening in order to get a full quote. Honestly, as an electrical guy, I always find a way not to work on the mechanical details. I’m still putting in many, many hours, on top of the hundreds of hours that I’ve already put into this design. A wise engineer I know says, “At some point, the sales guy has to shoot the engineer.” I could continue to work on this design forever, always refining and tuning, improving and tinkering, but at some point, I’ve got to call it done. That’s what this Kickstarter project is all about, giving this thing some finality. I’m really excited to see what you do with it when you get it. I think it’ll just get better and better.

  1. I think you have the full funding in the bag at this point. It’s been what, 10 days and you only have 1,200ish to go and 40 days left. Nice work!

  2. Under a $960 to go. Getting worried yet? It’s natural. 😉

    The nasty part is turning out 20 units and keeping the kit people happy.

    My advice, order it all, sort them into kits to mail out and then let them sit.

    Have a local solder bee and get friends to help build at least five while you do five. Check em over, and use their build feedback for the kit’s manual. Take lots of pics as you and make the manual out of teh build-a-thon.

    Then send out five kits quietly. Get that feedback, revsie teh manual.

    Then send them all. That catches the issues early.

    As for cases, they can come after. Do send McMaster mounts for the circuit board though, like eric archer’s stuff. Something to give it support and get it off the table. The same mounts can work with teh case, or do a ponoko case.

    and lots of blinky lites!

    • Yes, pretty worried. I’ve still got time though. That’s great advice. I hadn’t even really put much thought into the manual. I’ll get there. I can build one in about two to two and a half hours. If I try to do five, it may take four hours or so. I’ve got pretty solid soldering skills since it’s what I’ve done with a big portion of my life for the last seven years. I’ve got some quotes out to contract manufacturers that I’m waiting to hear on, but I’m not sure that I trust them. I’ll post about how that goes.

      The manual is just posted on here right? I believe that’s how Todd Bailey’s done it.

      The kit will ship with four standoffs.

  3. I’ve been getting the word out about this, got you posted on Matrixsynth a few weeks ago, tweeted & just posted on FB. My two cents: don’t worry so much about optimizing it, at least as far as Firmware goes, that can be updated later. Just make sure it works for the most part, glitches can actually be cool effects in a synth (like my K5000s, os v.1 had some weird effects in the filter if overdriven that were not the same in the next release…) Wish I had 200 extra $ to contribute to get one of these, but I’m a startup business myself so…

    • Thanks for the help and the advice. I’m wrapping up the hardware and feel pretty good about it. There’s a bit of 8 bitness in the filter that I know cannot be banished entirely. There’s a tradeoff between granularity, range, and bottom that must be made. Eventually, when you can’t get rid of a “problem”, it’s nice if it becomes a feature. I’m just obsessive about this thing. I’ll get over it. I know what you mean about supporting other people’s ventures. It’s expensive enough to pursue your own.
