  • Line 6 pedal board: Re-using the main board

    I decided to take a closer look at the main board from the Line 6. Since I might be tempted to put a simple display on the pedal board, in addition to a 16 character x 2 lines display, I decided to remove the digits from the (old) main printed circuit board (PCB). But taking…

  • Line 6 pedal board: Programming the expression pedals

    The expression pedal board contains two analog circuits for the two pedals, a simple switch and a LED. The connector has one pin for each, plus a ground and Vcc pin. The pedals use an infrared LED and photo-transistor that is slightly amplified by a transistor. They produce a weak analog value. I have not…

    After the midi episode, it was time to write the code to get the pedal press signals and control the LEDs for feedback. The pedal switches use what is called a resistor ladder: each switch is linked to a particular resistor, in series, and in theory, reading the resistor value at the end of the…

    The Line 6 Pedal Board will now receive an Arduino to replace its main board. The goal is to attach this Arduino to a computer using midi on a USB connector. For testing purposes, I will use an Arduino Duemilanove that I have on hand. I will use an Arduino sketch to test the midi-to-USB…

    I have ordered the parts needed to modify the main board. I am not sure yet which method will be used for the driving of the LEDs and switches, so I have ordered sufficient parts to be able to test two options. The first option is the lazy one. I will use an Arduino Mega…

    I have just purchased a new Behringer FCB1010 pedal board. Why? First, it does quite a bit of what I plan to do with my Line 6 pedal board. Second, it’s cheap. I know that this is an old design, that it has been around for years (at least since 2003), and that there are…

    To accelerate the building of the actual pedalboard, I purchased a used Line 6 Pedal Board from eBay. The price was right and I didn’t care about it working or not. I wanted the metal frame and the switches. This is a solid chunck of metal! Looking inside, you can see three printed circuit boards…

  • Side project: learning Processing

    As a side project, I thought it would be useful to learn Processing at this point. The goal of the main project, if you remember, is to be able to connect all devices, including computers, to the instruments and midi interfaces. I chose to use Processing (www.processing.org) to control how the computer(s) communicate with the…

    Ordering parts from China is slow. Well, actually, the ordering part is quick. Go on eBay, find part, buy: 10 minutes. Wait for slow-mail: weeks… Fortunately, there is plenty to do on the projects. I just hope that the parts eventually get here!

    The project evolves around an Arduino micro-controller. I use the Duemilanove because that’s the one i had on hand. It would work with any Arduino or Arduino-compatible board. Whatever is available and cheap. They sell for less than 30$. The Arduino will let you transfer midi data through it’s digital outputs, but to simplify things,…
