Getting the Pentax Optio E 30 digital camera (made 2009) back to life again

Correction, somewhere I say that the charge current is 100 mA but watching the meter is is (approx). 60 mA.. The Pentax Optio E 30 (say 2009 made) is a digital camera that makes extremely good and sharp pictures. But it was laying on the shelf. Reason: within 5 minutes the batteries were depleted, even high quality batteries (say a Ni Cad with 2200 mA-Hour). That has also to do (of course) with the voltage that must not go down to a critical value where the camera switches off, when the camera takes its necessary current to do the things that it has to do. But anyway. In this video a kind of poor man’s refurbishing of this old beautiful High Quality Pentax E 30 digital camera. So that it works again. Take two NiCad or NiMh (NiMh=better) batteries, solder wires to the appropriate electrodes( watch the video) and charge the camera batteries from “without” (an external source) to keep them “up”. Don’t make shortcuts, they will roast the batteries, be very careful in the wiring. I am (somewhat) sure the batteries can (normally….!) be charged via the USB port of a computer (NOT tested), but anyway. That will not solve the real problem: the extreme current that this (small) camera takes out of the NiCaD or NiMH batteries that depletes them within 5-7 minutes. With this “solution” you can connect an external voltage/current source between (say) 4 Volt and 7 Volts. Perhaps even somewhat more current/energy (raise the voltage, check the current) can be pushed into the cells, check the charge current with a MilliAmp meter, maximum say: 200 mA charge current to the NiCad or NiMH batteries for say 10 hours. Switch the charger off after that time! Don’t overload, take conservative values in the charge current etc. Don’t pop the NiMH or NiCad cells due to heat or a too high charge current.

When my video’s are reproduced or re-edited on other websites/channels you can not (!) be sure about the original content (=really working electronics) and important adaptations to the circuits. Be aware of that, I saw on the internet my circuits reproduced in a poor or even not proper way. I can not help that, sorry. Upload 30 december 2018.
