Project: RAD GT -- Custom Acrylic Case Worklog

Recommended Posts

sweet turbos :nod:

 

I usually look for quality before price. But I do price shop; if I can find the same (or same quality) product for less, then I'll go for the less expensive.

 

That's why I've got Bosch tools and not Skill or Black&Decker.

I finished making my PWM fan and lighting controller. It has 8 fan channels and 4 lighting channels (1 dedicated to the fan lighting). The fan LEDs are connected to separate headers from the fan itself.

 

First: the circuit I used

Edit: After testing the PWM fan controller with the Blackfire fans I realized that at low speeds the fans were "growling." By means of trial & error I discovered that if I replace the 0.1uF timing capacitor with a 100pF capacitor (raising the PWM frequency from 30Hz to 30KHz) the symptoms are resolved.

 

Installed 1 fan control channel to work out the layout

Here in the US I wasn't able to find anyplace that had the MIC502 fan control IC available in a DIP package; so I had to make due with the SMD version

Soldering on leads

1 DIPicized IC

All eight channels integrated on the PCB

Added power supply as well as headers for the fan LEDs and fan LED switch

Also installed headers for the case lighting control

And a pass-through MOLEX connector

The wiring for the power connectors will also be sleeved later on in the project.

Sleeved the wiring on the fan contoller

I also wired up and sleeved the switches for the case lighting as well as the power cables for the CCFL inverters

Damn man, you make it look easy. My sleeving came out like crap.

 

Looking sharp

 

Thanks; but TBH the sleeving was easy ;) (also the first time I've done it)

Sleeved the cabling for the front panel IO

Changing gears for a while; I cut out the MDF baseboard and rounded the edges

First coat of Lacquer paint

Back to the cabling; Wired up and sleeved the HDD LED, Reset Switch, and Power Switch w/ Power LED

Back to the baseboard again; Second coat of paint

Sanded smooth

I'm hoping to be able to get a piano-quality high-gloss finish; thus the use of the lacquer.

With the quality of work I've seen and the progress so far, I'd have to say >>> You've got some talent! Excellent work!

 

Thanks a lot; I'm trying to get all the details as best I can.

 

This is my first time working with acrylic and my first project of this kind; but I'm by no means a stranger to working with tools or soldering.

 

I actually just started working with Pro/E this summer and this is my first real-world modeling/design project.
