<h3> Screen Antics: Johnny Castaway Standalone Screensaver</h3> <p>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.</p> <h3> How to</h3> <h3>Printing</h3> <p>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.</p> <h3>Building</h3> <p>I used these Parts:</p> <ul> <li>Raspberry Pi 3</li> <li>5" TFT LCD Car-Monitor</li> <li>Adafruit 2.5W ClassD Mono Amplifier</li> <li>USB Soundcard</li> <li>8 Ohm Speaker </li> <li>Push Button</li> <li>Audio On/Off Switch</li> <li><p>DC/DC 12V Converter, like the RNM-0512S 1: Install <a href="https://www.recalbox.com/">RecalBox</a>. This comes with a functional DOS BOX Emulator. In DOS install the screensaver according to <a href="https://www.screensaversplanet.com/help/guides/windows/how-to-run-johnny-castaway-on-windows-64-bit-28">this guide</a>.<br/> 2: Solder the USB Soundcard. Connect the sound output to the amplifier. Connect the amplifier to the speaker.<br/> 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.<br/> 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.</p> <p>Any Questions? Ask in the comments. Have fun!</p> <h3>Print Settings</h3> </li> </ul> <p><strong>Printer Brand:</strong></p> <p>Ultimaker</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ultimaker 2</p></div><strong>Rafts:</strong></p> <p>No</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div></p> </p></p> Category: Computer
