Johnny Castaway Standalone Screensaver
Description
# 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](https://www.recalbox.com/). This comes with a functional DOS BOX Emulator. In DOS install the screensaver according to [this guide](https://www.screensaversplanet.com/help/guides/windows/how-to-run-johnny-castaway-on-windows-64-bit-28). 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. Any Questions? Ask in the comments. Have fun!
