the Voltage regulator i was supplyed for the K8044 was a 5v one and the product says that it out puts 12V how come its a 5V one?? The VR also get VERY VERY hot in use (to hot to touch) and the circut dosent want to work due to this hot VR
The K8044 voltage regulator provides 5V for the µcontroller, not for the outputs. If it gets too hot, you’ve either inversed it, or there is an assembly problem which causes an excessive current to flow from the regulator.
See box 6 on page 8 of the instructions, and the board layout in box 18 on page 13.
I think the flat face of the canister of the regulator packaging needs to be facing inwards, away from the edge of the board.
I don’t see how you would measure the current even if you knew what it should be, but perhaps it would be easy to check that you’ve got something like 5Volts on Pin 14 of the PIC microprocessor IC1 : half-way along the inside edge, near the A of CHANNELS.
Sorry, that’s the end of my suggestions. I don’t see how you can have 4.5v into the 78L05 from a supply of 12V if everything else has been assembled correctly. You need an over-voltage going in to the regulator to get the defined level out - I’m sure Velleman know that and would have designed it accordingly.
