Day of the Geek - Soldering Badge Kit (White with Copper Trace)
The Day of the Dead only comes around once a year but what if you could celebrate it any day you want? With this white version of the Day of the Geek soldering kit you will be able to learn the basics of soldering by being able to assemble a light-up skull badge! Each Day of the Geek kit takes about 5-10min to assemble with basic soldering materials (not included). Say no to sugar skulls and say yes to solder skulls instead!
Every Day of the Geek Soldering Badge Kit includes one white skull PCB, a CR2032 battery holder, a pin back, and three pairs of colored LEDs so you have the option of Red, White or Blue eyes. All you need to supply (besides a soldering iron and solder) is a CR2032 coin cell battery since it is not included to make shipping easier. Due to the different forward voltages and current draw, you shouldn’t mix the LED colors. Only use red with red, white with white, and blue with blue.
Happy Dia de los Muertos, everyone!
Note: Since this product is a kit, assembly and a basic knowledge of soldering will be required. The Day of the Geek Badge does not come pre-assembled.
- 1x White Skull PCB

Day of the Geek - Soldering Badge Kit (White with Copper Trace) Product Help and Resources
Mixing LED colors
Do not mix the LED colors. Due to the different forward voltages and current draw, you shouldn't mix the LED colors.
- The red LED: 2-2.5V @ 10-12mA
- The white LED: 2.9-3.1V @ 15 mA
- The blue LED: 2.9-3.1V @ 18 mA
(*For those, who have the knowledge: If you do want to mix the colors, please test that the setup will work before using them. Also, make sure when you test the LEDs that you are aware of the polarity. Testing an LED in reverse may damage (blow) the LED.)
Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Very cool. But even cooler with RGB LEDs.
Really nicely made and great looking little badges. I put together a couple of these as gifts for kids old enough not to chew on them or swallow the pin clasps. Rather than settle for one color LEDs I used 3mm slow fading RGB lamps and they work great. Assuming kids might be tempted to stare at the blinky lights and not wanting to damage any retinas I cut the outer traces and soldered a 10K resistor on each side, with one lead in each anode hole and the other in each battery holder hole. This dims things down to a comfortable level. Others may want to use higher or lower values or none at all, depending on individual taste. The LEDs I used stay in sync remarkably well, at least in the short term, and the effect adds to the fun.
Very cool / could use a switch
We've built many of these. They are so cool. Easy enough to put together and they are fun to wear. Battery holder is very snug. It could use an on / off switch. But maybe that's something I need to figure out how to add.
