We use to say Think Green but few ideas comes in mind about reusing old items by converting them to something useful.
Today I am going to present an exclusive Made in Greece by Kiriakos, a new product design. 8)
This is a DIY converter for charging TAMIYA 7.2V RC battery or 9,6V or 12V NI-CD packs of RC models.
Bosch AL60DV this is an remarkable True Pulsing charger for Ni-CD and major advantage this is that cells remain cooler at charging duration in comparison to constant current chargers (CC mode).
Pictured Bosch battery this is now an empty box, internal cells came to their end of life, but the box as you can see in the pictures below, it was converted in to a adapter this be compatible to old TAMIYA charging system.
Bosch AL60DV has thermistor sensing capability and if this charger sense that there is no thermistor inside the battery pack, then there is no Go about charging.
Therefore I did kept original thermistor in place, then I added one cable with TAMIYA 7.2V RC connector, and additionally I did added two spring loaded contact points ( 2mm hole diameter) and this is a voltage measuring point, or alternatively this can be used as another DC volt output, and connection will be made by simply attaching wires.
Personally I am very happy, because very recently I got as gift a used RC racing speed boat (https://www.ittsb.eu/forum/index.php?topic=1392.0) and this came with out charger.
Now I am able to use my Bosch AL60DV for both, and my rechargeable drill and also my boat ;D ;D
