Bravo

for me its somewhat theraputic, upuntil the moment ones purchased the pcb and five minutes later your in a panic revising an error and getting it uploadad befor its commited to production    nothing worse though than getting a delivery , building and then going What the blithering heck....

Last performance at the theatre this afternoon and then free for a week ( well evenings are free ) till other things kick in , so do that final work.  on the main pcb.  I hopefully have some dimensions on route for the rev-counter binacle so that will complete the set. 


 

i am also dabeling in guage steper motors and gps recivers,may be able to modernise the instrumrntation... but don't hold your breath.

This is my PIC-based stepper motor cluster made years ago that I never installed. Each motor is microstepped by a dedicated microcontroller. The artwork is engraved on the back of a non-reflective acrylic glass sheet and filled with paint. Regardless of tunnels and built-up areas, I would in no way trust GPS when approaching a speed camera:

nice work

I already have my digidash plans and this workstream has hopefully resolved some questions so it will be worthwhile for my own plans.



its now easier to design what i need than adapt something else ( usualy ) but incorporating available submodulse massivly reduces effort. 

Nice work TT, I have the CJH kit and he incorporated a flashing ‘alarm’ LED for me when the ignition is turned off:

Yeah an alarm LED is on the cards, simple enough. And a lights on reminder.

I am doing a bit of the design over the weekend but I am also waiting on some DC-DC buck converters to replace the Voltage regulator and need them to do a footprint for the PCB.  Also crafting a DOPS replacement daughter board, it will be further down the road but I need to lay out a basic pcb to get the fitment right with the main board. 

I am doing the stage lights next weekend at Coast Roads Festival. Hopefully after that I will have a couple of clear weeks of evenings to finalise the main PCB. 

Updated , realy just waiting on the voltage module now to get it sorted,

How universal of a fit is the original flex PCB across models/years? i.e. the layout of the things it connects

The Next itteration is at Hong Kong Airport. 

I have one of the CJH Kits knocking about somewhere.
I'll see if it can find it

Board has arrived, yet to test it at all.

also DOPS module V0.0.1 ... Straight on to V0.0.2 being created and now with JLC. I wanted it to clear the config options jumpers so they can be seen. And also I missed a voltage devider to the MCU input.. Even this may get revised again and use an opto isolator instead to preserve 5v

found my unused CJH kit

The flu, holidays and work have kept me busy recently. Good to see progress isn't slowing down on here though. It seems that some people have found some unused CJH kits too! I am jealous.

Anyway, after a lot of back and forth with the company who made my PCB design, I've finally made my assembly order with JLCPCB.


I made a few more upgrades and it should be here within 2 weeks. Can't wait to test it.

I have slowed down, it's been a busy month or two and I have had to turn my prototyping more to theatrical stage products as we need some new "things" at the theatre.  Away most of this week working a destival and then life should quiet down.
