I just finished building another NUBM34 monster "pointer". I used a Hercules 20V Flashlight for the host and it was a pretty good choice. The only slight issue is that it's quite front heavy so it can tip over easily. I used two 60V boost converters and a 20A momentary switch from O'Reilly's Auto Parts store. The first 50V converters I purchased were DOA so I got the 60V ones instead. I had to add some heatsinks to the copper plate because it gets hot very quickly. The drivers are set to around 50V and 3.5A and each one runs two rows of diodes in series.
