Mini Violin Badge
Constantin Craciun Apr 20,2020
This is a tiny electric violin powered by an 3V CR1220 battery and controlled by an ATtiny85 microcontroller. It uses a piezoelectric buzzer to make sounds when the four strings are touched. It does this by reading random values through an analog pin connected to the strings.It also features two side view LEDs on the back which are meant to shine through the PCB to light up the two F-hole symbols of the violin when sound is played.It also has a push-button for turning it on/off when long presse ...

The Light Badge
Mathew Feb 23,2020
The Light Badge is an electronic kit which utilizes an LDR (light dependent resistor) to detect lowering light levels and light a LED once it gets dark.This is a great example of an LDR in action.An LDR (light dependent resistor) or photoresistor is a resistor where the resistance decreases with the strength of the light.Schematics:This is how the circuit works: When exposed to bright light, the photoresistor’s resistance is very low.It drops to around 20-30 KΩ.Current travels through the 1...

happy halloween badge
Praddy Oct 21,2019
This is a halloween badge since halloween is near let's enjoy the party with a flashing RGB led badge .Keep in mind if you are using 9v battery then add the resistors and if 3v battery then solder the pads of a resistor connected and skip the resistance in the circuit. Do this for all the resistors.SORRY FOR THE LATE POST but designing the board took a little bit of time. now let us have a look at what is ATTINY85 module:The high-performance, low-power Microchip 8-bit AVR RISC-based microcontr...

RAF Lakenheath 48CS going away gift
Jeremy Ward Oct 16,2019
I wanted to make a great going away gift for a friends that was leaving us. After getting involved with the badgelife community at DEF CON 27 and making some shitty addons, I decided to take it a step further and make something really unique. I was a bit worried about how it would turn out given the complex shape and small tolerances of the board, but PCBway did an absolutely amazing job. This turned out better than I expected it to. Please visit my Github page to see videos of it in action or o...

PCBway superbadge
Hector Sep 29,2019
The goal is to have a programable badge with your logo on it or any logo you want so if you want to change it so it doesn’t have PCBway’s logo on it I recommend going to my github and changing the logo on Kincad. Or you could just make it with PCBway’s logo. List of parts is in the photo
