cults3d

Created this thing because buying one was too expensive. I use it during RC-Car races to talk to my mechanic or during flying my uav to to talk to my cameraoperator. Works fine. Distance aprox. 30-40m. The drivers headset is free to speak, The mechanic has a PTT-Button. Things you need to built: 2 Earprotectors: 3M™ 90563EC1, I found them only in Austria, but maybe other 3M would fit to 2 Intercomm-Sets (hard version) for motorbikes https://de.aliexpress.com/item/1005002967648428.html?spm=a2g0s.9042311.0.0.16984c4dDW1wJz 9 pcs switches https://www.amazon.de/gp/product/B08D6PHYV2/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 13 screws M2x6 2 charging ports https://www.amazon.de/gp/product/B0838G1F4X/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1 some cables and a few skills for insoldering 2pcs hard wire 47mm long for the pads fell free to ask, enjoy!
