Simhub belt tensionner case

# Simhub belt tensionner case This is my [Simhub](simhubdash.com) belt tensionner case *(more info on Discord)* There is 2 Arduino: - One UNO for my pedals vibrators - One NANO for the belt tensionner The UNO is powered by a 48 to 12v converter At this time, the relay doesn't work as expected. The relay engages as soon as the arduino receives current from the USB and should turn off when the USB is off, but the additional current provided by the 48 to 12v converter maintains 5V on the 2 arduinos. # BOM ## Screws: M6\*9 x 2 = square fixation M4\*9 x 4 = power supply fixation m3\*10 x 2 = UNO fixation m3\*10 x 2 = nano + usb + relais fixation m3\*10 x 4 = case top fixation m3\*10 x 2 = power supply socket fixation m3\*10 x 2 = USB support fixation M2\*4 x 4 = [hub usb](https://fr.aliexpress.com/item/4000062956240.html?spm=a2g0s.9042311.0.0.27426c37KNBhaW) m5\x10 x 4 = drivers fixations [little screws](https://fr.aliexpress.com/item/4000048003597.html?spm=a2g0s.9042311.0.0.27426c37q8mOaR) for NANO and relay fixation ## Inserts [m3*5.7 x 20](https://fr.aliexpress.com/item/4000232858343.html?spm=a2g0s.9042311.0.0.27426c37bjkQXZ) [m5*5 x 4](https://fr.aliexpress.com/item/4000232990523.html?spm=a2g0s.9042311.0.0.27426c37bjkQXZ) ## Connectors: [GX-16 4 pins x 3](https://fr.aliexpress.com/item/1005001881096050.html?spm=a2g0s.9042311.0.0.27426c37VWP6B4) [GX-16 3 pins x 2](https://fr.aliexpress.com/item/1005001881096050.html?spm=a2g0s.9042311.0.0.27426c37VWP6B4) [Micro USB socket](https://fr.aliexpress.com/item/32867946438.html?spm=a2g0s.9042311.0.0.27426c37q8mOaR) [Power supply socket](https://fr.aliexpress.com/item/10000001520449.html?spm=a2g0s.9042311.0.0.5d206c372EGUP3) ## Others: [120 mm fan](https://fr.aliexpress.com/item/1005002712334076.html?spm=a2g0s.9042311.0.0.27426c37VWP6B4) [48 to 12v converter](https://fr.aliexpress.com/item/4001252442039.html?spm=a2g0s.9042311.0.0.27426c37VWP6B4) [USB Hub](https://fr.aliexpress.com/item/1005003512825108.html?spm=a2g0o.productlist.0.0.3fe0118aZGBCTo&algo_pvid=c10e3572-d1dc-493a-89f9-68ac71540d0d&algo_exp_id=c10e3572-d1dc-493a-89f9-68ac71540d0d-46&pdp_ext_f=%7B%22sku_id%22%3A%2212000026121834916%22%7D) [Relay module](https://fr.aliexpress.com/item/32803442878.html?spm=a2g0s.9042311.0.0.27426c37biaoIR)
