hows it going...
Slowly, had a couple of packages that didn't arrive from China in the snail mail, the eBay one was refunded and I rebought and just got those on Monday but the actual Led's I bought through Aliexpress so had to wait 60 days for them not to show, then claim a refund and purchase again so they were sent last week, hopefully, they will get here quickly. With the led drivers I got on Monday it should allow me to get a fair bit more done in the meantime.
To say it's all going to be a tight fit is an understatement. I also realised when I got my hands on a torch that it's switch wouldn't work so then had to get another switch but with the current I am looking at I also needed to get some MOSFETs to do the switching.
Still to sort out how many 18650's I will use, I have thought if I run it at 12v it would mean I could use it of a car battery as well if I wanted, some quick calculations, however, tell me at full power it would be drawing about 35amp at 12v
