Blarp Cometh

Just a quick recording of a Blarp patch from today. Pure blarp, no effects or post production.

Say it with solder

Happy Valentines day :)

BLARP finished

Below is a quickie video showing BLARP in all her glory. She's sporting a nice copper clad top panel with my logo etched on. In the end I had some issues around both the lack of space inside and deciding what to build in the last corner of her boards so I decided that a breadboard would be the most versatile option.

For the final time, for those into CMOS/Lunetta etc, the final contents are;

2 x 4015 giving 4 x 4 bit shift registers
1 x 4040 divider
1 x 40106 providing 6 x Oscs (these are pretty wide range and go from audio rates down to really low freq)
1x 4070 giving 4 x XOR
1x 4070 set up as an XOR chain
1 x 4093 giving 4 x Gateable oscs
3 x AREGVCA (Attack Release Envelope generator and Voltage controlled Amplifier)
1 x 4069 giving 2 x triangle LFO
1 x 4046 as VCO
1 x 4011 Pseudo ring modulator
1 x passive LP filter with LDR control
2 x 3 input passive mixer
4 input resistance mixer with diode summing
Power output rails
Small kludge area
Breadboard

Data Ferox released today, with concretedog track

Data Ferox, released today, is the latest offering from the amazing Warm Data. Featuring tracks from many of the Warm Data roster and also me! My track is entitled "Big Bad Wolf" and was made entirely with Nanoloop 2.2 on my Nintendo Gameboy advance SP.

Feel free to listen to it and the other warm data releases, and if you like you can always purchase :)Here's the link Data Ferox

Etching stuff

Just a quick post. I've had a load of stuff for making/etching pcbs for ages now but decided that actually making pcb's for the scale of stuff I'm building is harder than just using stripboard. Anyway I decided I should still try etching so thought I'd etch my logo onto a panel I am making for the Blarp.

The glorious guts

It occurred to me today to take some shots of blarps innards, as you may see it's getting a bit packed in there! I'm glad I partialy built the enclosure as it has made the final boards/panels easier to work on. I added an XOR chain, 4011 "pseudo ring mod" and am halfway through adding a final pair of 4 bit shift registers. I am onto the final quarter of front panel and after finishing the shift reg's I'll be adding some 4018 AND gates (possibly diode summed inputs so I can turn shift reg bit outs into sequencer oneshots) and a couple more AREGVCA's.

I haven't posted any schematics for these but they are all findable on either

Or the MIGHTY MIGHTY

However if anyone ever wants any advice on getting into building any of this stuff feel free to get in touch if you think I can help.

BLARP, half finished!

Sorry it's been a while, I've been continuing with the machine started in the last post. It's turning into a monster project and I'm getting limited time. The beastie has acquired the name "Blarp" and is shaping up well. I've gone for a sloping panel as a compromise between ergonomics whilst both standing and sitting and despite it getting pretty cramped inside it's still small enough to be pretty portable.

For those into cmos/lunetta (!) it already contains, 2 x 4015 shift registers, 6 x 40106 oscs, 4 x XOR gates, 1 Kludgey area, 2 x 3 channel passive mixer each with jack outs (Jacks to be mounted in a flat panel at the top of the console), 2 x AREGVCA as designed by Richarius, 2 x 4069 LFO ala scott gravenhorst (modded for 9v), 1 x 4040 divider (only 5 outputs/divisions utilised). Also since this picture was taken a week ago it also now contains, 1 x passive LP filter controlled via LDR, 4 x 4093 gated oscs, 1 x 4046 VCO, and a 4 input resistance summer/CV mixer.

Not 100% as to what the final modules are to be as yet, I may include another shift register, another VCO and I'd quite like some form of active filter in there...but then I'd like more AREG's...a Sequencer, more oscs...more logic gates, a pseudo ring mod.....the list is endless!
