Percussibot Drum Controller Kit, Available Soon

I have received a number of inquiries about the availability of a drum controller kit. I am working on it. The kit will include a midi decoder board and 1, 2 or 3 FET driver boards depending on the number of output channels you need. Each FET driver board has 8 outputs.

The kit will include the assembled PC boards, LCD display with cable, three push buttons, ribbon cables and a “wall wart” 12 volt power supply(US only).

Documentation will include schematics, parts list with sources, instructions, suggestions about the use of the kit and a description of how it works. Source code is not included but hex files for programming your own PIC’s will be provided upon request. You are free to write your own code of course. The midi board can be programmed through an ICD connector on the board. Each channel on the FET boards use a 12F683 to generate independent PWM signals. These PIC’s need to be programmed off the board.

All IC’s are DIP socketed.

I’ll be selling assembled and tested boards to avoid issues with assembly problems.

The prices will be as follows:

Midi Decoder board $275

8 Channel FET board $325

(The prices do not include shipping.)

All spares can be ordered through Digikey.

I am not taking orders yet.  I’ll be ready to accept orders in a couple of weeks.

Please leave a comment or email me  if you would be interested in purchasing a kit.

Back Again!

Lots of water under the bridge since last posting, sorry for the delay.

Sally and I were well absorbed in two events. The East Austin Studio Tour took place November 14th – 27th.  Sally was also preparing for a show at the Blue Star Contemporary Art Center in San Antonio.

Our studio was open both weekends for the tour. (ours was number 59) It was a lot of work to get ready.  I was working on new photos from our California trip and I built a new set of actuators for a new drum set to join the one I made for Arcattack. I rented another drum kit and John DiPrima programmed some songs. I also helped Sally with framing her work.

Photo from Don’s Photo stream:

In between the two weekends of the E.A.S.T. Arcattack played a gig at UT in front of the Tower. At least 1500 students showed up. We had the two drum sets in front of the stage. I say we but I didn’t help set-up but I helped pack it up at the end.
Search on YouTube for “Arcattack UT” and you can find some video of the event.

I’ve added two new videos to the Gallery so take a look.  These were the sequences played during EAST.

Sally’s show in San Antonio is up through February 13.  You can see more about the show here.

Cheers!

A Fantastic Vacation in the Redwoods

My wife Sally and I just returned from a great, 10 day trip up highway one, north of San Francisco.   Sally had not seen the redwoods and I have fond memories of family vactions, so it seemed time for a road trip.  We also took the opportunity to visit some dear friends in the lost coast area, south of Eureka.

I hauled my 4×5 camera with me.  It’s a custom camera I built years ago, based on a 75mm Schneider Super Angulon lens and some surplus camera parts.  It’s a compact camera for a 4×5, but it has no shift or tilt adjustments.  It has a rare helical mount made specifically for this lens by Schneider.  It took me about 4 months to get the part when I ordered it.

Here is a Photo from the trip and a shot of the camera.  I’ve spent most of the day scanning about 20 shots from the trip.  I scan the negatives at 3200 dpi so they end up about 475 megabytes per shot.  Lots of pixels!

I’ll put up some of the photos in my blog gallery in a few days. (I do sell prints)

Latest on Midi Drumkit

I finished it!

The new kit has all metal components and attaches quickly to any drum set.  The controller is now more compact and contained in an off-the-shelf LMB chassis.   I now have a full set of drawings for the actuators and the controller design and a full parts list.

My goal was to finish it in time to ship out to Abu Dabi with the Arcattack crew. I had hoped to shoot some nice photos and a video before it had to ship out but I ran out of time.  That will have to wait till September when they return from their Europe tour.

Check out ArcAttack’s web site for show dates.

Here are a few pics from my phone camera:

Workin’ Hard

I’ve been busy working on a new, more durable and road-able drum kit.

Once done I’ll have a more repeatable and standardized kit that will be versitile.  I won’t be using any one of a kind components so the cost is a bit of a problem.  The first kit is being made to tour with ArcAttack!.

I’ve also revamped my code to clean-up some spagetti-code left behind when I rushed to finish it on the first pass.

I’m gradually attempting to port the code from the 8-bit PIC’s to a single PIC 32.  Bit of a learning curve there but it’s progressing.  It was helpfull to clean up my original code before attempting to port some it into C for the new chip.

I’ll provide some photos soon of the new components.

On a side note, I recently upgraded my laptop from Ubuntu 8.10 to 9.04 without a hitch.   Everything worked great, but…  Kpovmodeler would not save rendered files.  I found a patch that takes care of the problem for now.
