I hate those leaky NiCd drill batteries! They are always empty! You can just connect to any 12V Source like car battery or bench power supply which are capable to deliver more than 5 Amps. You can put some of the lead-fleece battery in your belt bag and are prepared to drill down a complete hangar.

This LED lamp is a quick project that can be done within a day. Only a few cheap components are needed to create a nice looking ambient lamp. No programming is needed, only the WLED firmware is uploaded to a micro controller via a simple tool. A 3D-Printed version simplifies the build process a lot but the cardboard version is also quickly made and can be made huge in size.
WLED is open source and provides many IoT interfaced including a web front end and an app that allows to control all the lamps in the local WIFI.

A first look on the ESP-Eye dev kit from Espressif. Its a tiny board with an on-board camera and a microphone. Its enabled by a phrase and detects faces. It is even able to distinguish different faces. Seems to be an awesome platform for future projects.
