About: Hey my name is Chris, welcome to my instructors page. I’m happily married with a wonderful son, he makes the best workshop assistant ever. Plus Binary options buddy 2 0 free download find a 7 year old has much more creative ideas than me.
Sometimes this website feels like a second home to me I spend so much time drooling over the projects I wish I had the time and money to make. Alas, It’s finally time for me to drop on you amazing people, my second instructable I call it The Pi-Switch. It’s a conglomeration of the work of many people but this particular build is, certainly and uniquely my own. Files Are Attached to this step the instructable assumes you’ve printed the part. Some more testing showed to me that PP24 directly to the metal pad is ground PP25 is right audio and PP26 is left audio.
Picture of updated solder pad usage attached. I recommend leaving the wires long 3-4″ you can trim them down or tuck them in later. I chose it because the clear top means you can see and understand exactly how it works. You should now have an audio jack connected to the pi, if you were to play sound with headphones plugged in you would have music playing clearly on this jack. I reccomend hot gluing the wires on the bottom of the pi and the bottom of the jack in order to secure the thin wires and also to protect them from damage and shorts. Unfortunately this little deal though fantastic does not output enough power to run the Pi-Switch.
It does however do a great job charging the battery which has plenty of amperage to power the pi, screen, and audio simultaneously for about 2-3 hours. I left the power on the pi open so that running out of battery just means you need to plug directly to the pi. I’m working on a better solution still. I may build a switching circuit. Power Leads:Lets start by looking at Picture 1 above you’ll notice 3 black circles and 3 red circles. Cut a single right or left leg off your switch and solder on a 2″ wire to the remaining center and alternate legs of your amputee power switch.
Hot Glue is cheap, quick, and easy. Solder the Speaker:Look at the picture above and solder one wire to each of the pads on the speaker as shown above. I’m too cheap for heat shrink so if you’re like me HOT GLUE! Solder the audio board:grab your PAM8302 look at the writing.
On the side where the board says 4-8 ohms solder your speaker wires to the two center pads as pictured above. Solder the Pi:There’s a picture of the pi above. Take one black wire from your power boost solder it to the black dot on the picture of the pi. Take one red wire from your power boost solder it to the red dot on the picture of the pi. Testing:carefully be sure the remaining black wire from the power boost and red wire from the powerboost aren’t touching anything. While pulling gently on the switch to keep it from falling back into the case put some hot glue on the backside of the switch as pictured above. If it’s not good peal off the glue and try again.
16th inch hole between the pi and the powerboost you can also dremel a hole. This should be on the side of the case where the pi’s usb ports are located. Slide the headphone jack into the hole and hot glue it in place. Finally, glue the speaker battery and audio boards in place as pictured above.
I put the speaker facing the plastic under the battery which i tucked directly behind the powerboost board. Then I glued the battery up against the sides of the 3d printed case. Ffinally I glued the speaker amplifier the top of the battery. So if you’ve done everything right this far you should have the pi, powerboost, the PAM8302, the speaker, the power switch, and the battery all installed and secured in the back of the pi case. There should also be one 10″ black wire and one 10″ red wire left.
Finally screw the four screws from the back panel into the brackets on the back of the screen and you’re fully assembled. I’ve added a controller connection menu, where the screen will tell you if both joy-cons are connected. Tada this is your first boot to the completed device. Now you just need to set it up with your own media and roms. Check back for updates with automatic controller connecting and parsec for computer to pi game streaming. I plan on adding a simpler way of pairing the controllers at boot to this menu. I’d love any co-op on this that’s offered.
