last winter I felt the need for a non-flashing bar light on my commuter. I have a non-flashing light on my helmet (very helpful for the "please don't pull out and kill me" moments) and a flashing light on my bars, but the strobe effect on my bars is a bit distracting in the dark and a non-flashing bar light would get me more forward visibility and let me keep the attention catching flashing light.
The mechanic at my local bike store also gave me the guts of a Lezyne all-in-one front light (battery is part of the light), so I'll be using the control/charging board from that, which simplifies things a bunch.
anyway, design will be 2 LEDs in parallel (Cree XP-G2 and XP-L) with 10deg optics, the Lezyne Macrodrive board, 2 Panasonic NCR18650B batteries (~3400mAh each) in parallel, momentary switch at the back. This will also be my very first "from solid" bike light, now that I have a mill. One cavity on the front for the LEDs with a nice thick piece of lexan, which should also give some side lighting. One cavity underneath for the batteries and driver.
Squared up a nice piece of alu to the right size last night with my facemill (about to start the larger side)
and bevelled the edges with a 90deg router bit
next up is drilling the holes for the charging port and switch, then starting on the LED cavity
