I'd really appreciate if someone could take a look at the board (see attachment) and give me some pointers on how to reduce the amount of jumpers, and especially and hopefully completely eliminate the layer named "bottom wires".
If you decide to try and route it, please don't move the connectors (CONN*), switches (S*), LEDs (LED*) and potentiometers (3-pin boxes marked R*). Everything else can be moved around freely as far as I'm concerned (even the headers J1 and J2), save maybe for the mounting holes. As for the line widths, most connections can be fairly small since the main parts are high-impedance, but the nets 12V_PWR and +12V carry a peak current of about 3A, so they should be wide. Personally, I used the "Power" line width for 12V_PWR, +12V, +5V and GND, and "Signal" for everything else. Since I'm hand-fabbing this and will probably be drawing the lines with a permanent marker, all traces should be at least 35 mil wide and have a clearance of 25 mil or greater.
Don't let the above make you think I'm just some guy going "do all of my work, please" - I /have/ done most of the work already, and I'm just asking for some help (for which the reward is my eternal gratitude!). Anything that can help me make my board design more elegant but still feasible to hand-fab is highly appreciated!
Many many thanks in advance, Peter
