Hi guys,
sorry for the late reply...
After some testing, I decided to change my 16F1503 receiver PIC to a 16F1508 which is equipped with an USART module. It's much easier to implement this way....
2 cents....... the LCD and LED's stuff aren't that badly affected by slight power supply fluctuations ... slight. The PIC's and IC's need good stable power 7805 or similar on their own circuit.

Would it be easier to have 3 LM1084 with that regular black heatsink:
- one to power all PICs and ICs.
- one to power the 3 LED strips.
- one to power the 4 LCDs.
That way I'd...
Option 2:
How about these with a fan?
25mm x 34mm x 12mm

Option 1:
Do you have a schematic for a reliable SMPS that can do 12V to 5V somewhere under 5A?
I don't have a final current consumption cause I haven't built a complete unit.
And most...
Paint on heatsinks is not for cosmetic reasons. Black heatsinks radiate more IR energy than bare aluminum ones.
As for the power loss on the regulator (either 7805 or 1084 or 317, it does not...
I bought a bunch of these a while back; aluminium heatsink with double-sided tape.
It fits just right on the back of a IRFZ44N (TO-220). I don't seem to have to bother with a screw/nut (unless...
I had 2 options originally:
- stay under 500mA and use USB power
- use a wall adapter and add a voltage regulator component.
USB power is no longer an option with the 4 LCDs. I don't have...
Re: Voltage regulation circuit 12V to 5V in 5A range
Are you sure you need 5Amps at 5 volts? That is 25 Watts of power.
Ioannis Yesterday, 20:13And about 35 Watts of power loss on the Linear regulator. This means that you will need a monster heatsink like intel CPU with a...
