Step 1: Parts and Tools

Here are the parts and tools needed to make this project:

Small glass jar that can fit in a laser cutter

At tiny 85

Arduino Uno for programming

Small circuit board that fits through hole in the top of the jar

Laser cutter

Soldering iron

Solder

2 LEDs any colour will work I used yellow

Computer with Arduino IDE

4 pin chip socket for at tiny 85

Wire

Cr2032 battery

Cr2032 battery holder (if you dont have one you can 3d print one)`

Step 2: Laser Engrave Jar

Using a laser cutter engrave this picture on the glass jar:

Step 3: Solder Circuit

First solder the 8 pin socket to the circuit board. Then solder the LEDs as shown in the first picture. Make sure to remember which lead is positive and which one is negative. Solder the two negative leads to each other and solder them to the pin that goes to the at tiny's ground pin (pin 4) . Solder circuit as shown in the schematic.

Step 4: Drill Hole Through Cork

Measure the diameter of each of the wires and add the diameters together and use a drill bit slightly larger than that. Drill out the hole in the middle of the cork and put 2 wires through the cork these wires will connect to the battery pack.

Step 5: Wire Battery Pack

Hot glue the cr2032 battery pack to the cork and solder the negative lead of the battery pack to the at-tiny pin 4 (ground). Then solder the positive lead of the battery pack to the at-tiny pin 8 (voltage in)

You can 3d print a battery pack if you dont have one. Here is a link to one that works great:
