This video will show you how to turn the Pi Zero into a little HDMI dongle computer. It works much like a Amazon Fire Stick or Chromecast in that you plug it into your TV, and power it using a USB port.
The whole thing basically takes advantage of a HDMI connector often used for FPV drone applications, and it allows you to plug the Pi Zero directly into a TV or monitor.
Unfortunately the Pi doesn't have Mobile High-Definition Link capability, so you can't power it directly through the HDMI connector, but I placed the micro USB port on there. Most modern TVs have USB ports in the back, or you could connect it to a power charger too.
Everything is enclosed in a custom designed 3D printed case, and considering everything is off the shelf, the final size isn't too big.
I've also wired a full size USB port to the back of the device, so you can attach external mice, keyboards, controllers, or flash drives so you can use it while sat on your couch or whatever.
The main difference between the other dongles and this, is that you have the option for many different operating systems, and thus, many potential applications. You could use it like a normal computer, browse the internet, use it as a media center, or as a retro games console. Just change the input source on your TV when you want to use it.
- Pi Zero W
- 3D Printed Case
- Vertical USB-A port
- Mini HDMI to HDMI FPV Connector
- Micro USB Breakout Board
- 4x 12mm M2.5 Screws
- 4x 5mm M2.5 Screws
- Thin Wires
Step 1. Print out the case using a 3D printer. The STL files are available under the source files link above.
Step 2. We need to wire up the USB ports to the Pi Zero, and glue them to the case. Use the pinout diagram and solder the USB port and micro USB breakout to the testpads and GPIO pins underneath the Zero.
Step 3. Now plug the mini HDMI connector into the Pi Zero, and screw it upside down in the case.
Step 4. Insert the HDMI connector into it's space and screw in the plastic brace over it. This will stop it from moving around.
Step 5. If you've got a long flex cable, fold it up, and tape it down so it fits in the case. Then screw everything together and you're done.
That is the Pi Zero HDMI Dongle, nothing more than a glorified case really, but it's nice to have everything in a small package.
I need to order a bunch of parts, but this one will definitely be going in the shop.
