Johnny Castaway Standalone Screensaver

Screen Antics: Johnny Castaway Standalone Screensaver

This is a standalone version of the famous Johnny Castaway Screensaver from the 90s. I always wanted to do this, so, let's jump right in. It's not that hard. You need some RaspberryPi and soldering knowledge. But it is pretty straight forward.

How to

Printing

Print Front an Back. I printed it in Wood PLA. Since there is some heat at the back of Panel, I noticed some bending due to the PLA low melting Point. But it was very very little. There is actually very little heat from this thing.

Building

I used these Parts:

• Raspberry Pi 3
• 5" TFT LCD Car-Monitor
• Adafruit 2.5W ClassD Mono Amplifier
• USB Soundcard
• 8 Ohm Speaker
• Push Button
• Audio On/Off Switch

• DC/DC 12V Converter, like the RNM-0512S 1: Install RecalBox. This comes with a functional DOS BOX Emulator. In DOS install the screensaver according to this guide.
  2: Solder the USB Soundcard. Connect the sound output to the amplifier. Connect the amplifier to the speaker.
  3: Mount the display. You may need more voltage then the pi could supply. So, in that case you need to convert the 5V up to what you need. I used a 12V DC/DC Converter. Read the data sheet. 5V in, 12V out ;-). You probably need to connect to the Composite Video. In case of the raspberry pi 3 there are some pads on the back of the pi, that is actually the composite video signal.
  4: I added a push button to start that screensaver in recalbox. Autorun wasn't working for me. I also added a switch to toggle audio.
