Built a MegaView yesterday, I've posted this on the UK forums I frequent, If this constitutes cross-posting please tell me and I'll delete it!
did a bit of a build log, it's not very exciting, but meh
So armed with my trusty soldering iron i set to it, first job was to solder in the CPU socket.
Then came the MAX323 chip (keen readers will remember this being the serial communications chip!
Next, a bunch of capaciters
and then the power regulator - and I used a heatsink compoung to ensure a good seal with the board to aid heat dissapation.
Soldering is getting very good IMHO (H = Humble
) :lol: :P the prongs on the far right are on the bottom of the board and are for the display to connect to.
More Capacitors, a few Diodes, the timing crystal and the DB9 connector.
Hex Standoffs for the display
The display, it's beautiful in the flesh. viewable in direct sunlight too :thumb-up:
underside again, the wiring for the switches are added
and back topside for the completed unit!
I was a bit dissapointed it only took me an evening, to build. However I've got to fashion a facia/case from scratch, so that will take some time.
I tested it on the way to work today, (I'll get action shots in a bit). At the moment it's power comes from a 9V battery which is hardly ideal. I'm hoping to tap into a 12 source from the DB9 cable so it's powerd via the Megasquirt. Just need to make a box then I can fit the switches and it's done!
pics of it running and a crappy vid
vid is here (right click save as please!)
I need to figure a way of powering it through the DB9 cable. apparently pin 1 is 5v, and I may be able to connect that to the output leg of the voltage regulator, but I'm not sure if 5v is enough to power the screen. :(
It'd make the install much cleaner if it could be powered via the serial cable!
