VC-1: Digital/Midi Volume Control

A user asked if I could design an FCB1010/PU-2 volume control. I love challenges… It took me weeks to get one working properly. The are two main parts to this: the analog side and the digital side. The analog side … Continue reading

PU-2: SD card capacity

I have just written a new version of the software that is used to convert a .CSV file into a Sysex file that the PU-2 can process. This version uses the SD card. Preleminary tests show that 2000 midi commands … Continue reading

SD Card reader: No Voltage required!

While testing a slight modification on the PU-2 prototype, I decided to test the current draw of the SD Card reader described in the previous post. I placed my multimeter in series with the 3.3 volt pin and measured 11 … Continue reading

PU-2: Data on SD card

Just in time! I received the SD card readers the day that I had planned to ship the first PU-2 Beta. I re-opened the boxes and fitted the card reader in each prototype. This is the SD card reader that … Continue reading

FCB1010 vs PU-2: Why do it?

While waiting for parts (I do have to get a better inventory “system”) to complete the Betas for the PU-2, I went through a short period of discouragement. It’s hard to stay fully motivated when the project is bogged down … Continue reading

PU-2: Last delay

As I’m completing assembly of the first of five prototypes, I decided to test the unit before putting it all into a box. Since I want the PU-2 to include a USB-Midi interface, I use the technology that I documented … Continue reading

PU-2: A batch of Beta

I’m getting comfortable making the PCBs for the PU-2. This is what a batch of 5 boards looks like, fresh out of the etching tank. I still have to drill the 800-plus holes and solder everything… patience… This is what … Continue reading

PU-2: Meet Beta!

The PU-2 made it to Beta. As you can see in the picture above, the PU-2 is an external module, linked to a connecting board inside the Behringer FCB1010 with a flat cable. The reason for the external moduleĀ  is … Continue reading

Making my own PCB: An exercise in frustration

I decided a few weeks ago that I would make my own circuit boards (PCB) for a while. At least for the first Beta. I succeeded, but the time and money invested make it a very “not profitable” adventure. I … Continue reading

PU-2: Additional functions

I’m getting a lot of feedback from musicians who follow the development of the PU-2 pedal board. A lot has to do with demands for more details on existing functions, but some people ask for functions that the PU-2 doesn’t … Continue reading
