Low Battery Indication LED for GBC

Why not just do it right the first time with 3V? A voltage regulator will waste a bit of power anyway, and take up more space.

Then his precious circuit wouldn't work.

Exactly. This way, you needn't design an entire new circuit from scratch.

That's what LI-PO batteries are for. :wink3:
If you used 2 of these in parallel, you could fit them in, and use the originally designed 7.4v circuit. Win-win.

Those things are a bloody centimeter thick!

If you can fit two in a CGB, plus the regulator circuit, along with the circuit for the battery indicator, then hey, more power to ya.

With a dremel, anything is possible.

No, no you see, two of those on top of eachother is THICKER THAN THE CGB.

Well, one battery would suffice, just wouldn't have very long life.

Here's a thought: Redesign the indicator circuit.
Hurf

That way you don't need to add a new battery, charging circuit, a regulator circuit, or have to physically modify the CGB.

:funny: You pointed out a truth in a way that made me laugh. :clap:

Yes, Basement_Modder, could you please redesign the circuit?

Why not just make the charging circuit external with a simple plug to the battery? That's how I used a cell phone battery, and kept the motherboard of my old phone just to charge it (in a radioshack enclosure, with a simple 4-wire plug between the phone's contacts and the built-in battery's contacts, with a plug on the outside).
