    Might be a stupid question and/or answered before, but how do you power up your units when on the bench? I don't have a spare car battery lying about.

    I started out just using a bench supply like this:




    Then I built my own test rig which uses a 12v 4A power supply:




    The Red switch simulates the battery being connected, the Green switch simulates the ignition switch. The red meter is supply voltage, the blue meter is current measured to a resolution of 1mA.
    The red push button simulates the interior light coming on or the reverse camera trigger, depending on where I have plugged in the 2 pin cable.
    There is a mini-speaker inside the enclosure which I use for testing Standard audio systems, and with the toggle switch on the top I can switch off the speaker when I'm testing Premium audio systems (amplifier located under my bench, along with my test DVD-NAV drive).
    I can also test steering wheel controls using the steering wheel buttons tied into the wiring loom.

    Got to say, Ben's custom psu has to be the ultimate for building and testing JagDroid.

    I just used a spare ATX PC power supply unit... stripped out the connectors motherboard, hard drive and pci-e connectors and just connected up to the 12V and 5V rails. Did the job for me... but then I did give up converting my own unit and left it for Ben to work his wonders.

    This may be of interest, if you have a spare ATX psu lying around... https://www.electronics-tutorials.ws...ch-supply.html

    My setup is far more shonky:

    A 12v 2.5A wall plug, with a few switches spliced in (and a fuse). The switches let me replicate permanent and switched 12V, and there's an extra barrel connector in case i need to drive the RTD or Arduino directly.
