BenBoost is a board that uses an 18650 lithium ion battery to boost a 3-4.5V input and give a 5V output (like the Laser Pointer). However, this board will allow for much higher output current which can be used for phone charging, Raspberry Pi powering and many other uses.

This project is a simple laser pointer that is powered by an 18650 lithium ion battery. It takes between 3-4.5V in and gives a 5V output which is connected to a small 5V laser pointer.

| Current Projects
The current project(s) that I am working on will be listed in this second column, along with progress updates and pictures.
|Li-ion Battery Charger
This board takes a standard USB input (~5V) to charge a Li-ion battery. This can be used with the BenBoost to supply 5V from a battery, and also to recharge the battery both while being used and when not being used.
Li-ion Charger PCB Render
I have soldered all of the components on the board, and the outputs seem to be working. I will test the board with a dead Li-ion cell overnight and see if it charges.
