Adapting it is as easy as a 3-terminal regulator IC to make the proper output voltage to match the D cells. 6 cells - 9 volts - LM7809 regulator. Too easy!.....Bolt the regulator to a little heat sink on the battery case. Hi Larry, Actually, I was wrong. It uses 3 "C" cells (not "D" - I just checked), but you're still correct - a three terminal regulator set for 4.5 volts. I suppose I could fit a dowel assembly with contacts and bring the connections out through something reasonably waterproof. The reg would probably have to be outside, though, as it's likely to throw off a bit of heat, don't you think? -- The reg would be barely warm, probably not using a heat sink at all. Use an LM7805 or MC7805 5V regulator and it'll work fine...... Larry W4CSC No, no, Scotty! I said, "Beam me a wrench.", not a WENCH! Kirk Out..... |
