- | <note important> | + | ===== Introduction ===== |
- | ====== Fat Shark Base SD integrated | + | The motivation for doing this modification came after having a chat with the author of [[http:// |
+ | |||
+ | Since I was already a little bit annoyed of carrying an additional tripod + the ground station case around (and the time it takes to set it up), I decided to order the Fat Shark receiver module designed for Attitude/ | ||
+ | |||
+ | ===== Requirements ===== | ||
+ | |||
+ | The extra part list for this build isn't long: | ||
+ | |||
+ | * a receiver module | ||
+ | * a dip switch, 3 part minimum, 4 suggested for power on/off support | ||
+ | * some servo wires or similar | ||
+ | |||
+ | The Fat Shark 5.8 GHz module for Dominator/ | ||
+ | |||
+ | Dip switches come in at least two varieties. The one used here is the smaller version of the IC kind. All types serve the same purpose but fitting something small is obviously easier when available space is limited. | ||

+ | ===== Modifications ===== | ||
+ | |||
+ | ==== Plastic parts ==== | ||
+ | |||
+ | The Base SD goggles top and bottom parts are hold together by | ||
+ | |||
+ | * rubber eye inserts | ||
+ | * two screws, holes in the bottom | ||
+ | * three plastic clips on the front side | ||
+ | |||
+ | Remove the rubber eye inserts, then screws and finally carefully pry the plastic top/bottom parts apart. There are some fragile connectors inside so don't push anything inside with force. | ||
+ | |||
+ | Once the parts have been separated, the bottome parts needs some modifications to fit the module and the dip switch. Start with a 7 mm drill bit and slowly drill from the bottom side where the screw hole is. This will remove the plastic pole that would otherwise block the receiver module. Note that this step may not be necessary if some other smaller module is used. Then figure out a place for the dip switch. The bottom was used in this build with holes drilled for the connector leaving the switch itself outside and usually also out of view. | ||
+ | |||
+ | | {{: | ||
+ | |||
+ | The top part needs to be carved a little bit too to fit the antenna connector of the module. The plastic is somewhat soft and using a sharp knife instead of a drill felt the best way of doing it. Test fit with the module until it looks nice. | ||
+ | |||
+ | | {{: | ||
+ | |||
+ | ==== PCB ==== | ||
+ | |||
+ | The PCB on the right hand side with the Futaba connector has the best place to insert the video and audio signal from the module and also has a regulator that provides +5V for powering the module. | ||
+ | |||
+ | * black: ground | ||
+ | * red: +5V | ||
+ | * white: audio, right channel | ||
+ | * blue: video | ||
+ | |||
+ | The left channel audio is one pin left from the right channel on the same row, if needed. | ||
