TP4056 3V3 load share addon board

I wanted to have a load sharing for my future battery operated project with the ability to charge the battery. There is a load of cheap TP4056 boards from China. None of them has the load sharing or voltage regulator on board so I made my own addon board.

Smrtokvitek has shared the board on OSH Park:

ATtiny45 motion sensing night light V1.2 D

This light is powered by an ATtiny45/85 which powers on the 14 LED lights when motion is sensed and it is in a dark room. The light sensor on the board will not allow the lights to come on if it is in a reasonably lit room.

It is fitted with a barrel plug for power, this model specifically with an L7805CV voltage regulator.

Programming the Open-V Open Source CPU on the Web

You can now program the Open-V on the web, and see the results in real time. The code is compiled in the web IDE and then flashed to a microcontroller which is connected to a live YouTube live stream. It’s pretty neat to flash firmware on a microcontroller thousands of miles away and see the…

Order from OSH Park

This board is part of Alan’s Raspberry Pi data collection system:

Mini-Monitor

The Mini-Monitor software is data acquisition software that runs on a Raspberry Pi computer. It is designed to post the collected data to the BMON web-based sensor reading database and analysis software, but the software can be modified to post to other Internet databases. The Mini-Monitor software has the ability to collect data from a number of different sources
