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.

|Laser Pointer

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.

| Ben's Universe v5 Released!

Ben's Universe logo

The newest version of Ben's Universe, version 5, has officially been released! It is a complete re-design of version 4, with all new "Projects" and "Resources" pages. The "Other" tab now contains items from the "More" and "Other" pages in version 4.

| 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.

Current status:

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.
