Well, the decoder is almost complete (trying to find the right headers to connect the servo to the board), and so far I have found out how much all this would cost me, knowing what I know now, and this is just for parts. Below is a list of parts plus the prices Product Code Quantity Product Description Unit Price Discounts Line Total 22-0822 11 3 Way 2.54mm Kk Molex Housing £0.13 £0.00 £1.40 58-0598 1 6n137 Highspeed Logic Gate Optocoupler £0.79 £0.00 £0.79 64-0098 1 10k Cr12 0.125w Cf Resistor - Pack of 100 £0.69 £0.00 £0.69 47-3416 5 1n4148 Signal Diode 75v 150ma (tru) £0.01 £0.00 £0.05 85-3077 1 12vdc 2.5 AMP International Plug Top Psu £15.92 £0.00 £15.92 20-0960 1 Switchcraff DC Power Socket PCB Mount 2.1mm £0.65 £0.00 £0.65 08-0919 2 1uf 2.5mm Y5v Dielect Ceramic Capacitor £0.11 £0.00

Although I haven't updated much for a while, I have been working on things in the backround such as a printed shield for the dcc decoder scriot i am writing for the arduino. So far I am on my second prototype but it will be the first with any components, mainly as the original was missing a route. Now the good thing is that you do not have to use it with dcc, but can use it with pushbuttons (omit some components and change a few linea of code.) The first picture is of the original prototype. PCB,  this one although could be used missed a connection to jp9 which meant that I would only be able to attach 10 instead of 11 servos to it. The second picture shows the updated version, this has been fixed so all 11 servos can be attached and used. It also, as you may have noticed, got a few more component holes on it, this is to facilitate a learn button for reprogramming, as well as to incorporate the required components to reduce a 12v supply to a 5v supply. All the componen
