    Hi

    I am wanting to a make a Firefly Jar , I just wanted to know if anyone on here can help me with making it and sourcing the items info as follows .

    This is the info from the web site , I will attach a drawing ! :

    DESCRIPTION: I'm calling it the Firefly Jar since it looks like a jar of invisible flickering fireflies at night.
    This project is a replacement lid for a mason jar. The PCB is 2.5 in diameter with a 55 mm round solar cell on top. This centers perfectly with a standard mason jar and lid collar. The solar cell recharges two 1.2V Ni-MH AAA batteries during the day. At night a P channel MOSFET switches on two candle flicker yellow LED's through a 2.1V LDO voltage regulator. The MOSFET only engages the LED's when the voltage on the solar cell is low and the batteries are above their 0.85V empty state. The LDO voltage regulator is an easy way to ensure a constant LED brightness throughout the life of the batteries.
    This would make a good DIY kit since the part count is minimal and all components are through hole.

    I made a firefly in a bottle,. pretty blue SKY vodka 750 ml bottle with 10 random flashing LED's.
    It uses either an AC adapter or 4 AA alk. batteries.
