LED project 300 L

[Ricard Fraidias]

take good before painting the screen to make the necessary modifications to the interconnections intergrar in both side .. like feeding db9 signal led .. as the 2 jack connector 3.5 each temperature sensor and the other to control the fans .. I had db9 hollow milling based dremel out the back to move forward the connector since the thickness of the aluminum plate 3mm side being very withdrawn .. so dremel in hand ..

on the inside I had to make a plate as 6 transistors incorporating LEDs .. one ULN2003AN for fan control .. also a voltage regulator to reduce 24v to 12v leds fans .. so everything is a little clustered on one side. largero take the aluminum itself and I screwed the plate itself is also subject right there. Transistors are placed almost sinks also not heated but better if they are suppose to sink over time ... I appreciate it for the cable I used an old DB9 connector from an old PC to a serial port and flat cable 10-pin connector .. (is utilizavan years for extra ports series boxes pc) and plate specifically designed to use this connector.

This weekend I made the change from the previous modified t5 led by the new screen still unpainted ... but I want to make a test a few days to verify operation

I put some pictures ...
