[QUOTE="bicter, post: 469916, member: 1240"] Last post disappeared into the ether :argh: Food for thought!!!! As the detector is battery operated, it's unlikely that Minelab will have applied much filtering to the P/S I/P. Using a DC-DC will introduce higher levels of noise into the detector than a linear regulator would. The impact of this is unknown. Using the LM2596 driven DC-DC, the spec suggests up to 3% ripple on the O/P (Up to 0.5v). I think the most effective solution would be to change the battery pack to a 12V style, with sufficient AH capacity and regulate to the required voltage using the LDO I suggested earlier. Using the LDO will minimise the power loss compared to a normal regulator such as the LM317 and therefore provide longer running time for the battery pack. [/QUOTE]
