Hi folks,
Have a nice one in, where would like to sort 90v and 1.5v from maybe 4 C cells using an inverter rather than heaps of 9v batteries in series.
Had a look on Ebay but buck converter modules rarely give more than 30v with a 4.5v input, so thinking of a few turns on the buck coil, rectified and added to the output.
Gather set only needs 15m/a at 90v so less than a couple of watts.
Wonder if anyone has had a try ? - Chris.
