Anyone know of of schematics and parts list for building your own constant current boost driver?

found this a while back on the forum. don't remember from who so i don't know who deserves the credit but ....
simple design based on a LM3410 should drive a phr fine. don't know about a red. never built one for red. hope this is a start

found another one i remembered by woop..

TPS61201 laser driver
this is a layout for a constant current laser driver using the TPS61201 chip. it should work with down to 0.3v input , u1= TI TPS61201, I1= coilcraft LPS3015-222MLB, C1-3= 10uH ceramic, C4= low value ceramic, Rsense= selected using R=0.5/I (where I is the required current). this driver should not be used without a load. and LD- must never be connected to Bt-. power source can be a single AA cell.

As I've posted a few times before.... the original Manufacturer
Design Engineer gets the Credit for the circuit...

Here is the Data Sheet of the regulator mentioned above..

The board layout can be credited to the person that laid
it out...
