Raspberry Pi 4B Chase

<b>Update 28-09-2019:</b> Implementing the touch sensor proved to be more difficult than expected. I will therefore put the idea on hold for now. However, I will leave the design online. To make up for it, I have added two new designs online. The keyboard version has been tested and works fine. <b>Update 23-09-2019:</b> Unfortunately, I discovered that the sensor plate control did not function error-free. The Raspberry Pi sometimes turned off on its own. I have narrowed down the errors a bit, and it appears to be caused by the built-in resistor. If anyone has a solution, please let me know. Until then, I advise against printing the cover with the touch sensor. Here are a few implementations of my Raspberry Pi 4B enclosure. I looked at several enclosures and read the comments. Based on this, I created a new one from two good enclosures. The basic model is from "0110-M-P" and the modifications for the fan and connectors are from "John_Sinclair". The MicroSD slot was enlarged slightly (to about 13.5mm). In addition, you will need: * 4 M3 x 20mm screws (attach cover and bottom) * (Alternatively, use M3 x 18mm screws) * 1 Noctua NF-A4x10 5V fan * Optional: + 4 self-adhesive rubber feet Additional information: If you print the cover with a logo, you should use a support structure for the logo. (Alignment of the cover "Logo on Print Bed") I also designed a version that allows you to use a real on/off switch ( Touchplate Taster) from Niko's blog post: https://bitreporter.de/raspberrypi/richtiger-an-ausschalter-fur-den-raspberry-pi To do this, you will need: * 1 sensor + https://www.amazon.de/Kapazitive-Ber%C3%BChrungsschalter-Selbstsichernde-No-Locking-Arduino/dp/B07PNL873R/ref=sr_1_8?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=TTP223&qid=1569099421&s=diy&sr=1-8 * 1 short lever switch with cap + https://www.berrybase.de/bauelemente/schalter-taster/mikroschalter-taster/kurzhubtaster-printmontage-vertikale-montage-12x12mm-h-7-30mm * 2 jumper cables + https://www.berrybase.de/raspberry-pi-co/raspberry-pi/kabel-adapter/gpio-csi-dsi-kabel/40pin-jumper/dupont-kabel-female-150-female-trennbar?number=DUPONT-40P-FF-20CM Prepare the touch sensor: * Prepare 3 jumper cables and connect them to the plate. * Insert jumper cables into the following GPIO pins: + VCC - Pin 1 (3.3V PWR) + I/O - Pin 5 (I2C1 SCL or GPIO 3) + GND - Pin 9 (GND) Prepare the switch: * Prepare 2 jumper cables and connect them to the switch. * Insert jumper cables into the following GPIO pins: + I/O - Pin 5 (I2C1 SCL or GPIO 3) + GND - Pin 9 (GND) Connect the MicroSD card to your computer. In the "config.txt" file, add the following lines: (#Ansteuerung An/Ausschalter) do not use the parentheses at the beginning and end dtoverlay=gpio-shutdown,gpio_pin=3,active_low=1,gpio_pull=up After the first start of the Raspberry Pi, you can now use the switch to turn it on and off.
