0.1 Schematic

PDF

I did this on peafboard. I always use the kind of perfboard where three holes in a row are connected – no idea how it is called.

looks like this:

i made myself a PDF to print out and plan the layout.

For power supply i used the 5V and ground line from the ave5. If you use another supply, make sure you connect the grounds.

Take care when tinkering with devices that are connected to mains power. You and you alone are responsible for what you are doing.
If you are not sure what you may and may not touch inside the device and how to find a point with 5v then this project is not for you.

The 4053 IC (i used CD4053BE) has three switches that each connenct a common in/output to one of two in/outputs.There are different ways of connecting those switches to the bent circuit.

I decides i would devide the wires comming from the ave into two groups. All those wires go to the middle pin of an on-off-on switch.

The pin for the down position goes to the 4053 switch x common pin for one of the groups. Up position goes to switch y common pin. For the other group the pins go to one of the two in/outputs on the 4053 switches (also up -> x, down -> y)

This way the Points in one group are shorted for all on-off-on switches that are in down or up position without the 4053 doing anything. Points with switches in the same position, but different Group, are connected through the switches in the 4053.

The remaining 4053 switch is used to pull the points with up position to ground for one of the groups.

What is this?

I build a simple device to make a circuitbent Panasonic AVE5 controllable via MIDI. It is build around a PICAXE 20×2 and uses a 4053 IC for switching and 6n137 optocoupler for MIDI input.

At the moment the firmware only reacts to MIDI Clock.

It should be easy to adapt this device for bending other devices like NES, Sega Mastersystem etc. basically everything that runs on 5V and can be bent using switches to short different points in the circuit.

this is a work in progress…
