Overclocking a Spy Pen

08/13/2011 5:50 PM

I have one of those silly Chinese spy pens that scales up the 640 by 480 video to 1280 by 1024. This results in jerky video at 12 frames per second. I was wondering if it would be possible to swap the two clock crystals inside for ones of a higher frequency in order to get a better frame rate. I think that one crystal is for the image sensor and the other is for the processor.

Nope! The one crystal is for OSD clock and the other for everything else. But the bottleneck is at microSD card writing speed. Try a true class 10 card for best results. S.M.

I have tried sdhc cards and normal cards in the pen and they are both the same. I have seen that on some cameras there is a crystal next to the image sensor.It looks like a small metal cylinder. In this spy pen the two crystals are shrink wrapped. Would changing the processor crystal for a higher value increase performance?

Read about class rating. It's printed on card but there are unbelievably many fake claims too. Test it's writing speed on a computer. Forget about crystals. S.M.
