Here's the dash panel.
I'll do a detail on this later but a this point it's just an access panel to the fuses and solenoid so we used it for an interface panel,

at this point it was the initial shakedown so a lot of features were left out until we'd run it through the initial tests.

We're about to add an ammeter to the top dash and a 12V lighter socket, aux audio input and an hrs usage meter to this panel.
(Remember we still have only put 500ml's of petrol through this so far). I refilled with 1.5 litres 2 weeks ago but we've started it once since then. I'll take the meter as a Zero.
The layout and population is fairly simple. The Dash units are available online cheaply, from me they're about $20 but I test and then epoxy them first.
The amplifier units the same, about $7.00 on line but I test and coat in epoxy plus add 3.5mm aux dash connectors. For about $20.00.
The antenna is almost done and I've used a similar system that I've used for some planes and helos so I'm good with the performance for simple FM radio.
The knob I use now is a guitar control that's a gibson SG replica but of course anything..

Quality is a direct experience, independent of and prior to intellectual abstractions.
