How to Quickly Test
Remote Controls
(reprinted from the
July '03
DRSNews)
If you’re like me, you have 5 or 6
remote controls that wander all
around your living room. We’re even seeing them used in major appliances, air conditioners being the most
common so far.
When one of them stops working,
here’s a simple way to tell
whether it’s sending any infrared light to your TV, VCR, DVD, or
cable box (or air conditioner).
Just point it at a
cell phone camera, digital
camera, camcorder, and if it’s working, the light will show up in the
camera's LCD
viewfinder! Fast,
easy, and COOL!
I
purchased a small sensor many years ago for this very purpose, but if
I’d thought of this first, could’ve saved some money. Try it
- it works great!
The CCD’s used in digicams are sensitive to IR even though our eyes aren’t.
Wish I could remember where I
originally found this trick. To whomever first discovered it - thanks!
