Is there already such a thing anywhere? I couldn't find it here or through Google image search.
wanted: high-resolution photo of 50g internals

I could probably provide you some. I have an HP50G disassembled. What sort of pictures did you need?

I think Eric is looking at potential housings for his DIY Calculator...

Just looking for a high-resolution photo or scan of the circuit board.
Thanks!

I just found my tools to re-open my broken HP50G (bought it for $5.00 on TAS). If you're hoping for some clues on how the traces are connected, you may be pretty disappointed. It's a multilayer PCB with very few traces visible from the front and back sides. The only exception is the LCD daughter board -- well, at least the portion not covered by the glass... Anyway, I can take some photos tomorrow during daylight. My camera does a pretty poor job inside with the typical yellow lightbulbs

I'm not concerned about traces that aren't exposed.
Thanks!

Yes, but indoor incandescent lighting is just weak compared to natural lighting. Although I can set the white balance, the picture is grainy from indoor lights (unless you have lots of lights and flood the room). Anyway, if you're looking for the photos, I posted a link in a later thread since this one was getting buried:

Your "grainy" is probably from using a high ISO (sensitivity). Use the lowest ISO your camera has (looks like 80 or 100 for your A2200; DON'T set "auto"), and just make a longer exposure (there's no reciprocity failure for digital sensors!). You may need a tripod, too, though. Also, use the self-timer to avoid motion/shake when you press the shutter button.

When I take photos of my gear I use a big flash with a diffuser. The reflector is aimed against the ceiling. This results in enough light and does not cause any flares or reflections. |
