x0xb0x, Open Source Hardware and TB-303 Clone, Has a Renewed Future; Q+A @ Create Digital Music

Open source hardware may not sound like something that would produce a huge musical hit – unless you’ve met the x0xb0x. A clone of Roland’s legendary TB-303 bassline generator, the open version offered not only greater afford-ability than the now-rare antique, but expanded possibilities for hacking the hardware into a musical device you could love as your own, all with the backing of an impassioned community… Read more -

Nice interview with Willyzyx.

x0xb0x is back and shipping again – say hello to Willzyx Music

X0X Open
My X0Xb0X Lg
Adafruit is thrilled to be working with Willzyx Music, the x0xb0x is back. In our previous post & announcement we let everyone know that we would unable to support the project in the best way possible and we would be figuring out what we can do to help people get kits again. So, big news – we were very lucky enough to find someone who can devote the time, resources and support to x0xb0x – Meet James of Willzyx Music, he writes -

I just spent the last 10 years working in a San Francisco music shop and I really liked my job. I loved that I was helping people make music and that’s something that I still want to be a part of. Me and my wife have been making plans on moving to Taiwan for a number years and in 2009 we took the plunge. During 2009 I was selling completed x0xb0x’s on eBay under the name of bitcrusher76, it was a success and I am continuing on with the opening of my new web store willzyx.com.

My goal with Willzyx Music is to keep supplying the x0xb0x community with Parts and Kits. I have spent the last year building up a stock pile of parts and will bring the Kits back at an affordable price. Any new projects that are produced from Willzyx will have the same MIT open source license, so you can hack, modify and commercialize any of Willzyx’s original designs.

We want to thank James for being part of this with us and we’d like to thank all of customers, fans and everyone who has made the x0xb0x one of the best open source synth projects – LONG LIVE x0xb0X.



x0xb0x project status 2010 – new forum

388577204 5616F073Fa B
New forum for the x0xb0x project going forward in 2010!

The x0xb0x (Adafruit edition) was available as a kit that includes all parts necessary to build a x0xbox: PCB, case with CNC machined faceplate, components, buttons and knobs, AC adaptor, pre-programmed microcontroller, and (of course) poorly xeroxed assembly manual*…You supplied the sweat & tears.

We have made 9 runs of 100 kits each. All but one of the components in the kit are through-hole.We had a great run and we are currently exploring how to best support this project in 2010 – so far we’ve made the project completely open source and we will have more updates in the month of April with what’s next for our role with the x0xb0x.

Because of demand and time/cost to make these kits -starting in 2005 we created a “waiting list” where interested kit makers could sign up to be notified if and when the next run was available for purchase.This list was a “spot in line” for the kits Adafruit Industries may make based on pricing, time and demand. We did not accept any payment in any form until the kit was shipped and the listee was notified to place their order with a special password for that run. This worked out great, we never “held” funds unless a kit was sent. The waiting list was simply a “back in stock” notifier for potential x0x customers.

At this time (4/2010) the waiting list is closed and no longer will be used. Our data retention policy for this list is as follows — We do not retain email addresses or names, if you signed up you can safely assume the list has been deleted, you will never be contacted by Adafruit or anyone else. We respect your privacy. We hate spam…. We will have more updates soon in the next days and weeks, we wanted to post this up as we updated some of our pages and re-did our inventory.

The plural of x0xen is x0xen

We have another run of 100 x0xb0x kits in the shop. If you missed a previous run, you have 7 days to email support@adafruit.com before we close the old list

If were not on the list before 5/14/07 do not email me, its not your turn yet

x0×515’s custom acrylic case

Not much more I can add to this incredible hand-built clear case…Keith S. is quite a perfectionist! (Or maybe he also has a laser cutter?)



Check out high-res versions of these photos, as well as gawk at the other mods people have done, at the x0xb0x gallery page!

x0xb0x demo #69

Here is a nice-n-easy x0xb0x demo video with good sound (yay), thanks to Booster69
It’s to celebrate that I’ve finally gotten off my ass and am finishing off run #7 after a vacation-y november and retail-rushed december

Bored? Build a simple supply

This is a classic circuit, but until now I hadn’t gotten around to building one. Its useful whenever you need a floating supply or if you need a quick way to poke a signal voltage into a circuit. (I suggest it for people building and testing x0xb0x’s)


Click here for step-by-step instructions on how to build your own.

Starring x0xb0x #601 and Acid Cat

kthxbi!

First sketch: Arduino beta tester

I installed Arduino IDE 009 since I figured I should learn this stuff if I’m going to sell Arduino’s (and clones)

My project today was to build a simple NPN Hfe (Beta) meter to do some tests on the now ultra-rare 2sc2291 matched pairs. My multimeter has one but I wanted to make sure I was testing with the same setup as the one in the datasheet, with a Vce of about 6V and Ic = 1mA. The results are in the x0xd0x wiki

This is the breadboard circuit I used:

its similar to the one described on the x0xb0x page, but with the op amp swapped around for NPN’s

The sketch is rather small, I just take the two analog measurements, do a bit of math and spit out the calculated beta. I checked this against my meter and it matched up for lower betas (although not for higher ones, which may mean I’ve got current leaking into the opamp)

MemPot & x0xb0x video

A teaser from Misusage (who made the awesome TileToys a few years ago)…a cute circuit idea to automate knob tweaking! Microcontroller + digital pot + glue = MemPot, a speed-adjustable programmable ‘memory’ potentiometer. Seen here manipulating a modded x0xb0x, yum!

See more videos and DIY instructions (soon, I hope)

x0xb0x adventures!

I was supposed to have three pieces in the Columbia College A+D gallery show D.I.Y. show “pass it on” but the x0xb0x, spokepovs and mintymp3 decided instead to go on a road trip!

x0xb0x boards available

I’m back from a successful endeavor at SXSW interactive, and I’ve uploaded x0xb0x board layout files to Sourceforge. You can grab them from the x0xb0x download page To generate Gerbers, use EagleCAD

If you just want to buy the PCBs, they are available for sale in the webshop!

x0xb0x in Circuit Cellar!

…well, kinda


Back pages of recent C.C. have this ad.

Turns out this “dirt-cheap and not very english-speaking” PCB fab house in China needed some clip art and thought this circuit board fit the bill:

FYI, x0xb0x’s are actually manufactured by Advanced Circuits in Colorado, which is my recommended PCB house: they have not let me down ever!
