I wanted a 445nm laser at low power that could actually be used for pointing.
My favorite host for a low power side-button build is the Atlasnova red laser pointer. It is pretty easy to open and most of its components can be re-used for the 445 build. The host looks like this, classic slim <5mW...
I wanted to try this for a while now: take a 3*AG13 keychain pointer and turn it into a BR. Finally got around to do it.
DX Sku.12323 was chosen as a host.
It is a cheap 650nm pointer running on three AG13 / LR44 alkaline batteries.
The original driver 'circuit' consists of a single...
This is my first attempt at a real pointer with momentary side switch.
I used DX sku.565 as a host for this build. Its a red pointer that runs on two N cell alkalines (DX description says "1*R1 battery", which is incorrect). N cell batteries are the same diameter as AAAs but only 2/3 their...
