Required Hardware
Important:
- Arduino Mega
- Ethernet Shield with the W5100 chip(I would prefer a seperate board, not the shield version)
- Some cabels
- A small button
- Soldering iron and a few other tools
- A 3.3V voltage regulator(What i used)
- 5mm LEDs
Optional:
- Dupont connector set
- Panel mount RJ45, USB-B and power socket
Step 1.1
Remove the potentiometer caps and the t-bar handle.
Step 1.2
Remove the screws on the backside and the outer case.
Step 1.3
Seperate the main board from the front panel.
Step 2
Remove the main processor
Step 3.1
Replace R59 and R62 with a bridge.
Step 3.2
Replace R60 and R61 with a 12Ohm resistor(I only had 10Ohm when i did the modifications).
Step 3.3
Swap the ground cable from the led panel board connector
Step 4.1
Remove Q2, Q4 and Q6
Step 4.1
Bridge the outer pads of Q3, Q5 and Q7
Step 5
Cut the voltage supply trace of the t-bar opamp
Step 6.1
Build your 3.3V regulator and connect the input and ground to the legs of the 7805 as seen in the picture below.
Step 6.2
The 3.3V output connects to the old 14V rail as seen in the picture below
Step 7
Connect a long wire from the 9V pin of the 7805 to the power input pin of the t-bar opampAnd another wire from the power rail of the t-bar opamp to led panel connector
Step 8
Remove the button caps and the 14V lamps that are inside the button. Cut the LED leads so they are about 5mm long and push the LED inside the button so the leads go where once the lamp pins were. The pins will bend out a little as the distance between the holes is not exactly the same size. You can test where ground is with a multimeter. Do that for Every. Single. Button on the board.
That's all the hardware modifications that are needed.
