Having lived most of my life in the south part of the world, fireflies have never really been a thing for me until recently. You may have seen some creative designs lately where people create a jar that looks like it houses a firefly, but now there’s a chance to a build your own!

This Firefly Jar solder learning set includes a 10mm LED and tilt switch, along with the necessary components and a small jar. When you finish soldering everything, you can use the jar as a night light and turn it off simply by turning the jar upside down.

Take a look at the video below to see how it looks when everything is finished.

Relaxing outside on a hot summer evening you might catch a glimpse of fireflies as they perform an ethereal bioluminescent dance. Maybe you even been able to catch a few, trapping them in a jar for your entertainment. Recreate a bit of that magic with a DIY electronics project.

This FireFly Jar Kit presents a different, and much longer-lasting, bottle of blinkies. Instead of actual fireflies blinking, is emulates the bugs’ effect with tiny 0603 LEDs and 38 AWG wire. An ATtiny85V provides lighting control, and it should be able to function on its CR123A battery for 6 months or more.

While you can build this type of contraption yourself, the item listed here is available fully-assembled, as a kit, or a PCB only. In either case, you don’t have to mess about with making your own PCB or perf board assembly, which could be well worth the $30, $20, or $10 price tag. Personally, I much prefer to avoid soldering as much as possible, especially if the terms “0603” and “38 AWG” are involved. Soldering concerns aside, be sure to check out the representative video of this type of faux firefly effect below:

The jar presents a nice subtle LED effect, but for something on the opposite end of the spectrum, why not check out the AuraCube, with its 512 RGB LEDs flashing away to your heart’s content!
