One side of the molex connection done. Should make unplugging the dash nice and easy from now on :D

Increasing the toner didn't make any difference. But using two printouts, in exact register, seems to have made the black parts a lot more opaque. It's difficult to capture like-for-like images in the dark because my phone camera adjusts the brightness, but the white bits still look ok in the dark, and the black bits look a lot better. I could live with this I think.

If you're stacking registered layers then maybe try printing the back layer on acetate? That way you'd get the benefit of the extra black toner without doubling up in the white areas.

Good idea! I'll try that.

Just fitted Chris's pcb to my van, mines a late model diesel dash with dops, separate tacho and digital clock so took a little extra working out but working through the old foil pcb it was quite easy.

The main reason for switching to Chris's board was I run a smaller steering wheel so from my driving position I can't see the indicator or main beam warning light so I wanted to swap them into the lower position, and put the glow plug up at the top.
Anyway, it all worked out fine and here's the results

And back lighting

That's great, I'm glad your mod worked out - thanks for the photos.

great stuff Chris. :ok
Why have I just spotted this thread? :rofl

How about copper clad board with the symbols etched out of the copper so the light shines through the board?

Replacing the dashboard plastic PCB

Postby bigbadbob76 » 10 Aug 2018, 17:54

I saw this today and thought of you Chris.

It's 1.5mm thick white plastic with a black laminate over the top.
The lettering is etched out of the black leaving the white.
Light shines through the white nicely.
It reminded me of a machine a mate used to work making hotel room signs etc. Like a mini milling machine. He used it with similar laminate.
That was 20 yrs ago though so I don't know if such machines are still used.

Hello Chris, have you thought about adding an acoustic/low coolant level temperature alarm integrated?

And to sell the kit on ebay?

Very good work.

Hi Nickelo

Interesting idea - you mean a buzzer that comes on whenever the temperature gauge LED comes on?

I'd considered putting the kit on ebay, but I prefer to keep it as our little secret - where the demand is manageable!

That would be one way to do it. I'm sure there's someone out there who could cut a black vinyl panel to go over a white insert. I may have a work with some of the sticker stalls at busfest..

I've got a silhouette portrait vinyl cutter which I've used to make custom vinyl decals for the kids bikes, I'm not sure if it is accurate enough to cope with really fine detail like the polarity signs in the battery light icon but I was very surprised at how small a detail it can cut.
If you pm or email me the image you used when you printed it out I'm happy to have a play in the evenings and see if I can make something work.

Here's my attempt with one print on paper and one on ohp transparency.
Looks ok to me.
Now I need a hole punch. Haha..
