hi all, been lurking a while but finally found some workshop time and thought id share my new creation
started this one about 4 years ago (maybe more) but at the time didn’t have the tools necessary to do half the work so it got forgotten about.
now iv got some new tools, and built some bits progress has started
specs:
2 x XML U2 driven at 2.8A
Derwichtel driver
prolonged momentary piezo switch - absolute buggers to get hold of
ahorton aspheric
2s3p bike battery pack (awaiting delivery from KD, hopefully panasonics)
dimensions 72x36x100 (might be smaller now )
most of the above is old tech as it was purchased years ago, but will do for this prototype.
suppose some pics would be good here??
home made dividing head for rounding the case
new mill
origional cad drawing
still needs a fair bit of work cleaning the body up and actually testing things, then ill hopefully anodize it all and then finally put it all together.
thanks its had a few hours here and there over the years, i wouldn’t want to add it all up!
the lathe is a denford viceroy, very similar to the boxfords. it need a lot of work as its was badly abused at a school and is missing lots of bits, but it turns out fairly good work.
did a bit of quick testing today, just to make sure things would actually work, there’s plenty of room in the back of the housing for the driver and all the connections, so i can make all the connections on leads out the rear cable hole then push it all back in on final assembly
for this test iv only got one led and aspheric in the housing, the other is on a heatsink with a ledil iris.
driver and switch seems to work ok short press is on/ off press and hold changes mode 100-70-25-3% can hear the pwm on the lower modes but its not too bad, should improve one the driver is fixed in place
managed a crude iphone beam shot
beam is about 30cm wide at 2 meters so about a 8-9 degree beam angle
no idea on power numbers at the moment, my power supply was saying an input power of 5.5V at 1.8A in high, though that cant be right. will have to dig out my other meters and test the currents.
no its a 2.8A driver originally designed for a P7. at the time of purchase it was highest reliable current setting for an xml, only the sst50 could handle 5 amps back then
well iv not done much recently but have made some progress
managed to find some of the lenses at illumination supply so orderd a few up,now got 2 spares
also managed to drag out some acid and set up a makeshift anodizing bench with a couple of buckets. tried for a black wich didnt come out perfect but isnt bad
looks a bit grey in the photo but its actually reasonably dark, but also has a reddy/purple hue to it
and i cant find the other one so now i need 2 more
