How Do I make the Blast door from the Doom 3 project ?

[Mach]

The one that I linked to is:

Board dimensions 3 5/8" x 1 5/8" with the heatsinks extending 1" above the board. Too big?

I did as Crimson suggested when I soldered mine together except I soldered a 3 way screw type terminal block where the pot is supposed to go.

As far as knobs go, what are you looking for? I've got some new smallish ones from another project that look like silver stereo knobs. BTW, it doesn't come with a knob.

Mouser's got a ton of knobs of all shapes and sizes

Would it be possible to make the same thing here only with the door panels being about fifteen inches long? Also, can you open the door while the PC is not powered on?

[Crimson Sky]

You can make the door any length you want; however there are a few things to consider. You'll need 15" overhead roll space just for the door plus the length of your gear arm. You are talking about at least 22" overhead travel depth to allow the door and mechanism to roll up completely. You will also need a more powerful motor and gear system than the CDROM components we used.

To answer your second question, you can draw 5V power from the PC while its not on using the standby power leads directly from the PSU.

I must not have made it clear.

The width is about fifteen inches but the door only needs to cover about four inches in height. I'll try using Sketchup to show you what I mean.

[Crimson Sky]

You said 15" long... length implies height when you are talking about doors. And go and start your own thread regarding this please, so we don't hijack this one.

Just an update:

I have the unit painted (Pics soon).
I also have my Bidirectional DC Motor Speed Controller assembled and will be testing it out soon.

Just a quick update to let you guys know I'm still working on it.
I have been sick all week and have not felt like doing much.
I'm sitting back and watching my son make his version of the actuator which I am very impressed with! look for his topic soon along with pics.

Well I thought I would let everyone know whats going on with the project.

First due to me looking at a picture of Crimsons final assembly wrong and thinking the actuator should be mounted the way I have it caused all kinds of problems!

This was not noticed until I tried to use the speed controller it just could not raise the door without being helped.

So I took a time out and looked over the photo's and discovered my mistake!
The actuator should be mounted horizontal not vertical as I had it.

I have since re-designed the way it mounts in my unit and it works great now!
I was also able to shorten the length of it and I needed to do that as it was very close to the power supply.

Pics Soon also a Video so bear with me I hope I have not let this topic die.

Thanks for all the great support

Ok here are the pics of the reworked actuator.
As you can see mthe actuator is now horizontaly mounted.

Here is the Bidirectional dc motor speed controller it was fun to assembly.

In this veiw you see the door fully raised and the actuator sticks out the back some but not as much as it did originaly this will be covered by a styrene box.

I have a video but Google video is down I will post it later

HELL OF A JOB! I can't believe someone besides "Old Man Crimson" pulled this off. Mind if I ask, where did you pick up that DC controller?
