Here are described some
modifications I made on my
to increase its autonomy
and add some useful functions.
The original baffle and 55W/12V halogen lamp has been replaced by a 621Lumen 50W/12V LED and 3D-printed bracket.
- much less power consumption,
- narrower and lighter powerpack.
The original 12V / 8VA lead acid battery has been replaced by a 12V/12VA lead acid gel battery, for a longer autonomy and lifetime.
The 50W of the LED are more than enough for the nomadic use : providing light while packing the equipment before going back home...
A 12V/5V 3A converter with 2 USB connectors has been added. it allows to power a nanoPC (Lattepanda).
As well, a adjustable voltage regulator with a RC connector has been added, to power a dslr (or something else).« 2019-06 : Flexible titanium plate for 3D-printer's heatbedPolemaster / Skyguider-dec-bracket adapter ? »
