Final Release: ‘Loose Memories’ by Derek Scott

2012-05-12T18:14:26Z

Ladies and gents, we would like to thank each and every one of you for your support over the years. We would also like to thank all the musicians that were willing to share their awesome music with us, and with the world. With that, we are announcing that DoBox Recordings will be shutting down operations. It’s been a good run, but things have changed…times have changed…and it’s now time for us to change.

We leave you with one last release. ‘Loose Memories’ by Derek Scott is the result of experiments with an inline series of analog delay effects fed by extremely sparse synth patterns. While most of the recordings are atmospheric meanderings, there are four bangers that highlight the fact that exact synchronization or quantization is not always needed.

We hope you enjoy the sounds of the final DoBox release, and we’ll keep all our previous releases online for your listening pleasure until further notice. Thanks again, and please keep supporting all the talented musicians out there.

Peace!

‘Shadowman EP’ by Blurix

2012-05-11T03:43:32Z

The Diggarama label’s head honcho Izidor Radmanovic, aka Blurix, returns with another raw and energetic EP. All three tracks are full of movement and emanate Blurix’s distinct sound. One thing is for certain, they know how to make music for the dancefloor in Croatia. Enjoy!

I think anyone who's built something in secondlife will find @tinkercad to be pretty similar… only with bools and no cost to build. so fun! #

an OpenSCAD script for 3d printing potentiometer knobs

2012-03-31T21:42:24Z

I learned some OpenSCAD!

This script has a *lot* of variables you can tweak. I don’t even feel like I’ve put everything into this script that I want to, either.

an incomplete list of parameters you can adjust:

knob radius
knob height
shaft hole radius
shaft hole height
set screw inclusion, radius, and location
flatness of shaft hole
rounding on top (thanks very much to http://iheartrobotics.com for the articles on edge rounding!)
indentations
directional indicators
plus a lot more!

About

One of the most stressful things about making multiple copies of an electronics project is reliably locating interface controls that you like. Maybe you can locate them one time, but can you locate them a year from now? two years from now? And how much do they cost?

For example, I found some slide potentiometer knobs at Mouser.com for about $0.50 apiece two years ago, and they ran out of them… forever. I tried sourcing them elsewhere, and the best I could find was a seller that had them for $4.00 apiece (!!wtf!!). So that really sucks.

One strategy is to buy in bulk. But, buy too few and you may run out and pay twice for shipping. Buy too many and you end up with unused knobs sitting around not making your money back. That also sucks.

Round potentiometer knobs are somewhat readily available. But still, they can be from $0.80 to $5.00 each, and if you can’t find enough for your project, that can be problematic. Mostly I’m tired of paying multiple dollars for things that should basically cost $0.25 apiece. Aesthetics are important too, so having options beyond what’s out there is nice.

A different strategy is to print them yourself as you need them. No shipping, no running out, and you get to call the shots on how it looks and how it fits. Now, I like this way. Plus, for my project, making the knobs just goes along with the rest of the stuff I’ve done myself.

Well... some are better than others. Limited success is better than no success at all.

Synthseqr sneak peek

2012-03-29T20:06:50Z

I was able to test out synthseqr live with my band Haptic Synapses, the night we also played with Antacid Crew, and it was a lot of fun! I posted a video of us playing and synthseqr is in there, but I wanted to make a new video to show the progress I’ve been making. Derek Scott is also working on some great functionality coming soon, and of course he’s the chief architect of Steppa, which synthseqr runs on top of. So check it out and let me know what you think.

IDEO’s arduino programming tool add-on — retreive source

2012-03-20T03:02:40Z

Ah. Oh. Yes! Ooh! Maybe!

Dave Vondle from IDEO Labs posted a really cool add on for the arduino IDE that lets you retrieve the source for an arduino you physically have but don’t already have the source for. Essentially, if I understand this concept, I can tie the arduino mega inside each beatseqr to the source online, so that when you want to see how it works and want to change something on it, you can just plug it in, launch the arduino IDE with this add-on, and get the source from the internet. Sweet! I have asked a question about a minor detail, but overall the concept is really good, and I think I’m going to give it a try.
