I just purchased a set of filtered HD 144 lenses for my 8500 AC and am wondering if I use the HD 145 calculations for distance when setting up the projector. Screen size is 88" x 66".

Thanks,

MAK

Hi,
Best to set up the pj on a table or cart and determine throw based on
the raster usage, or just keep all your settings to stay within your
existing wear pattern. All the calculations will be off, as they are
for diffferent projector models. 144 will need to be closer than
145's in any event.

Oh yes that's very good, the heck with throw distances.....
Is there any possibility of regenerative braking?
I have been riding mtn for years, lots of bikes here....
Hills aren't getting any easier though...hohoho!

It's possible to add regen braking but not worth it, as with Lithium batteries you can carry so much energy with so little weight, there's not much to gain.

The other problem is regen braking can generate HEAPS of current, and you can't get it into the batteries fast enough.

Sensible for an electric car, but not needed on a bike.
