I have an ADS Instant DVD Video Capture device that I use to transfer photos and video clips from my cameras to my computer. I use the clips to make personalized DVDs using ULead Video Studio 10 Plus.
PROBLEM: The ADS shuts down after 15 minutes of recording.
DIAGNOSIS: The ADS overheats due to inadequate ventillation and/heatsinking. ADS help advisors disagree with me.
FIX: Add a fan and heatsinks to the IC fins.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Original Device - Front View
Low profile device - small vent holes on back of top. No vet holes on the sides or bottom.
Step 2: Original Device - Rear View
Low profile device - no vent holes. Excellent connectivity.
Step 3: Add a 3.5 X 3.5 Inch, 9/12 Volt Ventillation Fan to the Bottom
Take the unit apart - with due care for static or displacing components. Use fan as template. Cut a hole on the bottom of the case a little smaller than the circular fan housing.
Step 4: The Fan Installed and Wired
Use an appropriate 9\12 volt power pack and wire it to the fan. Secure the wires away from the fan. Install a line connector to facilitate dismanteling. Mount 4 stand-offs as shown using a cable tie under one stand-off to be used as a tension relief for the fan supply leads.
Step 5: Vet Holes on the Top Cof the Case.
Use a 3/16 bit and add several vent hole to the top of the case as shown. The hole should be over the fins of the ICs on the circuit board inside the case.
Step 6: Add Heat Sinks to the 2 IC Fins
Cut 2 aluminum heatsinks (1\16x3\8x1\2) and dril mountong holes to fit each of the IC fins. You may have to file down edges or otherwise fit the heatsinks in such a way the the DO NOT come in contact with ANY OTHER PART AFTER ASSEMBLY is complete. Use heatsink compound between the sink and the fin and mount the sinks using small nuts ans bolts with lock washer under the nut. Double check your work and do a trila assembly of the complete unit. DOUBLE CHECK for shorts.
Step 7: Final Assemble - THE BUG
Carefully assemple the ADS: 1) install the circuit board in the bottom part of the ADS checking for shorts involving the heatsinks and mounting screws. 2) Insatall the case top (the heatskiks should NOT be moved out of place by this action. 3) Install the 4 mounting screws that secure the top to the bottom of the case. Voila! You are ready for a trial run. I like to plug the two power packs (ADS, Fan) into a power bar with an ON\OFF switch so that I can be sure to turn on both ADS and FAN at the same time.
I have run the modified ADS for 3 hour non-stop without a problem.
