This guide shows you how to put together your own Raspberry Pi based tally lights for Blackmagic Design ATEM
This build guide is created specifically for our tally light solution for Blackmagic Design’s ATEM switchers using a Raspberry Pi Zero W.
There are many ways to put this device together. While we are using Raspberry Pi Zero W in this guide, you can use any Raspberry Pi boards with the 40-pin GPIO including the modern Raspberry Pi 4.
Skip ahead to Step 2 if you purchased our DIY kit, as that already comes with a pre-prepared memory card and all the parts you need
Download and install the Raspberry Pi imager from the Raspberry Pi Foundation website.
Download and open the image file. It should automatically launch the Raspberry Pi imager.
Insert the microSD card into your computer’s card reader
Select the memory card that you’ve just inserted in the imaging software
Select “Write” to start imaging the card
Trim off the cathode (shorter) end of the LED
Trim off one side of the pull down resistor
Solder the resistor to shorter end of the LED that you have just trimmed off
Repeat the same process for the 2nd LED as well
Place your assembled LEDs on the Raspberry Pi board using the following pins.
Program LED anode: GPIO 17 (pin 11)
Program LED pull down resistor: any ground pin (pin 14 used in this example)
Preview LED anode: GPIO 27 (pin 13)
Preview LED pull down resistor: any ground pin (pin 20 used in this example)
You may have to bend the pins or use hook up wires instead to locate the LEDs where you want them.
Apply solder and trim off any excess wiring
Mark the location of where you’ll be drilling the holes in the casing
Drill holes in the location you have marked.
We usually like to start with a 1/16″ drill bit to help centering the hole, and then finish with the 1/8″ drill bit (assuming you are using the 3mm LEDs supplied in our kits)
Insert the imaged microSD card, and place the circuit board into the enclosure.
Plug in the power supply to boot up the Raspberry Pi.
If you have one of our pre-imaged SD cards, wait about 60 seconds for the the device to boot up.
If you imaged your own card, you’ll need to wait for about 5-10 minutes before you can start using it as the image needs to perform a set up process on first boot. The device will reboot multiple times during this process.
When both the program and preview LEDs stay on for more than a minute, this means that your device is all set up and ready to go.
If only one LED comes on or none comes on, you’ll have to go back and check your work. 🙁
Finish setting up your Raspberry Pi over the WiFi network with the instructions on the main page.
That’s all there is to putting this together!
You can show your support for the further development of this application by purchasing one of the Raspberry Pi kits from us.
If you think that this is too much work, don’t worry! We carry an inventory of pre-assembled units as well.
