FPV Screen Enclosure

thingiverse

FPV screens are expensive for what they are so when I found a cheap FPV video system on banggood I decided to print a case for it. This has built in battries, charger, receiver, XT60 and screen cover. Its designed to be something you throw in your bag and pull out as needed without worrying about finding battries or antennas. There are two main body parts one is if you want an internal lipo the other is without. There is a screen cover, a flap holder to hold the screen open and a back peice. The antenna is built inside the case. The reception is good considering its sitting on a battery and metal screen. If you wish to charge using the USB connector you will need a slightly longer USB plug than normal. Note: You are making something with built in Lipos & charging. Don't attempt this if you are not good at soldering or electronics. Try not to blow your house up! --- Required parts --- The screen and receiver board: https://www.banggood.com/RX5808-5_8G-48CH-FPV-Receiver-with-5-Inch-HD-Displayer-Snow-Screen-Monitor-DIY-For-FPV-Goggles-p-1309235.html 5.8GHz FPV antenna (you can get an SMA and solder it to the board or solder the antenna on directly): https://www.banggood.com/2-PCS-65mm-2dBi-IPEX-IPX-FPV-Omni-Directional-Brass-Antenna-RG178-p-1213263.html?rmmds=search&cur_warehouse=CN 1x switch: https://www.ebay.co.uk/itm/252106861027 2x lipo battries (optional) (you can use other battries but keep their thickness below 7mm): https://hobbyking.com/en_us/turnigy-nano-tech-950mah-1s-25-50c-lipo-pack-walkera-v120-x100.html 1x voltage regulator (optional): https://www.ebay.co.uk/itm/401012912499 1x charging curcuit (optional): https://www.ebay.co.uk/itm/112746837161 An XT60 (optional) 2x 3mm LED's of diffrent colours (optional) 2x 20mm M3 screws 1x M2 3mm screw 2x M2 6mm screws 2x JST connectors (to connect the battries) (optional) Hot glue and hot glue gun Double sided tape --- Assembly --- Prepare the electronics: - Remove the two LED's from the charging circuit. - Solder some wires to your two 3mm LED's and connect them in place of the two surface mount LED's you removed from the charging circuit - Solder the two JST connectors to the battery pads on the charging circuit - Take the screen power wire and solder one end to the switch and the other to the power out of the charging circuit, solder the other side of the switch and unconnected charging circuit output pad together - Solder the XT60 to the voltage regulator input. Calibrate the output voltage use the potentiometer on the regulator to about 4.5V so you dont blow up your screen! - Solder the voltage regulator output to the charging circuit input - Remove the SMA connector cable and either solder the antenna direct or solder an SMA to the board - With all of the above ensure you observe the correct voltage polarities Put it together: - Push the screen into the slot (it should be a tight fit) - Use some double sided tape to hold the battries on the back of the screen - Connect the ribbon cable into the screen connector on the main board and rest the board ontop of the battries - Push the XT60 into its holder and screw the switch into place - Glue the charging board into place so it sits behind the opening for the USB (it can be tricky to align it correctly so be careful) - Glue the LED's into the LED holes - Glue the control board in place on the back pannel - Plug in all the connectors - Push the back on, its designed to hold itsself on without screws - Screw the screen cover onto the front of the box - Slide the flap holder in place and put a 3mm M2 screw in the hole to stop it coming out If it flames drop it like its hot.
