PCI Time Base Corrector –> StandAlone Unit (OLD)

Major Parts Needed:

Project Box to hold the parts below – $4.50
12v Fan that fits in the box – $5.00
Small switching power supply w/molex connector – $5.50
PCI Time Base Corrector card – $199.95

The Time Base corrector itself and the power supply produce heat. There is a transistor with a heatsink on the TBC which gets very hot and should definitely be cooled well in order to keep the unit working for a long time. This is a Sanyo-Denki PicoAce 60mm 12v DC fan, chosen because of its excellent construction and quietness. This fan was picked up from All Electronics for ~$5.00

This is a small switching power supply with a molex connector (computer) output. This is required to power the PCI TBC and the fan. This unit was picked up at All Electronics for ~$5.50.

This is the PCI TBC itself; click the picture to see a larger view. I got this at SmilePhotoVideo for $199.95, the cheapest you can get a full frame TBC brand new. The cheapest external unit, the TBC-1000 costs $279.95. Now, this project takes that PCI TBC for $199.95 and adds ~$15 worth of parts to produce the $279.95 unit for much less, and you can have fun while building it.

This is an old project box I found in a “junk box”. You’ll have to find one of these on your own which will hold the TBC and PSU in some configuration.

Because of the size of the box I have available, I need to mount the power supply partially above the TBC card. These are PVC pipe parts cut to length to hold the PSU card at a good distance above the TBC. I filled each end with hot glue and screwed them in place.

The first major step is to cut the holes in the box for the TBC connectors. Take a ruler and figure out the center of the holes, and drill them. Make them a little larger than the actual connectors on the card because S-Video cables need to be able to fut in the hole for a good connection.

The next step is to install the fan. Measure and drill the hole for the fan in a location which will provide the best cooling for the large transistor/heatsink on the TBC card. I chose to have mine blowing in, and the air goes diagonally through the box to cool everything rather well. Now is a good time to make some plans as to where you want your power cord to go. Drill an appropriately sized hole and put a rubber gromet in it.

Now that all the holes are drilled, you can install the cards in whatever configuration you choose to use. As I said earlier, my box confines me to having the cards on top of each other like this.

Just another view…

And another showing the fan and power cord.

The completed unit. It looks neat, works great, and saved me some money. Good deal!
