AlumaxX said:I didn't know how many leds I was going to use in the end. I knew I wanted to place four seperate groups of leds, that can be switched on and off seperately, but not how many leds that there would be in every group. Adding one or more leds wasn't a problem doing it this way and I had enough room.
sev said:A 25W Resistor would get mutantly hot. A wirewound resistor might as well be a 25W bar heater in the case, cause all those LEDs would consume nearly 7 watts.
Lazn_Work said:How do you figure? If the LED's use 7 watts, then the heat generated would be 7 watts, same as a bunch of small resistors.
The resistor will only "use" as many watts as flow through it, being rated at 25W only means that it can handle that much before it lets the magic smoke out.

KikBox said:This is just a great project! I finally got caught up on the whole log and I am very impressed with your technical skill and your design savvy. Not many people can master both but you clearly have.
You have a lot of hardware in that box but you manage to keep it all clean and neat. Awsome job!![]()
AlumaxX said:I use the same tools for the acrylic and the aluminium. Before I can saw into the material I drill a hole to get the sawblade in. Next I use this saw

The blades can be changed and you can buy different kind of blades for metal, plastics and wood.
Next thing I do is file the edges, just use normal files. You can see them on the table in one of the pictures from the acrylic grill.
To give it a good finish I use sandingpaper. That's all I use and that's one of the reasons it takes so much time to finish the project.
