In this instructable I'll be building a simple yet effective Electronic Magnifier.
To begin with, I already own a ClearView electronic magnifier. I originally got it from our local tip which has a junk shop. At the time I had no idea what it was for. What I really wanted from it was the carriage that moved the base around (X, Y Axis for small CNC). When we got it home, I turned it on and was pretty excited to see what I had. The LEDs that light up the base were only half working, so, considering that's all that was wrong with it I decided to fix it and use it for electronics and precision work rather than tear it apart. I was also completely blown away by the price of these units. They start at around $2000+ which makes them quite unaffordable for a lot of people.
We took the ClearView magnifier to my partners mother to have a look and see if she wanted it. She pointed out a number of problems and this is where the build idea got started. The problems she pointed out were:
- The ClearView is pretty heavy. Made of a steel frame, its not easy to just set aside.
- Its footprint is big, so keeping it on a table can be troublesome.
- The ClearView model I have is an older version running on an old school analogue AV signal, so a regular monitor can't be used and CRT sets are bulky and again, heavy.
Build time for this version was around about 2 hours.
Parts and tools required:
- Screw driver
- Drill and drill bits
- Self tapping screws
- Pipes from a vacuum or large curtain rails or strong piping in general
- Some form a stand or heavy duty clamps
- Camcorder/zooming webcam/Camera with LiveView feature. Preferably a camera with some sort of Macro feature. (I used a 5 year old Sony Camcorder - one of the first 1080p's)
- Tripod Head or something you can make an adjustable mount with.
- appropriate cabling
- Glue/Thermoplastic/Putty (I used thermoplastic)
