The 0. The above left display are hooked up to a Arduino Nano V3 and the one to To The Wide - Os Drongos - Out Of The Box (Vinyl right is connected to a Arduino UNO both cards are feed from a digital waveform generator with a 0. Both cards shows a steady steady like frozen! Maybe I will look in to coding a calibration funktion ;0.
The design has a radius side with the sensor that follows the radius of my Linn LP12 platter. This project is open source so I will publish my print files for anyone to tweak. Further enclosure Ideas includes. Simple display bezel for the display for if you like to build a turntable integrated version. A version with built in small rechargeable battery for about min operational time to get rid of the bulky mini USB.
Looking forward to your thoughts. Some more pics below. Boot up splash screen. If you want this splash screen then you need to modify the splash. Arduino nano inside the 3D printed box. The board need to be trimmed a bit in the corner facing the curved part of the box be careful to avoid damaging the pcb. Display show no rotation sensed or speed out of range. Temporary installed. LP) thin 2 wire usb power only cable can To The Wide - Os Drongos - Out Of The Box (Vinyl wired directly to the Arduino Nano board and the be routed under the platter to be hidden, that will also allow us to close the lid with the tachometer in place :D.
This might be multi version project! Portable version with rechargeable battery. Portable version powered by USB power supply. Installation version, fixed sensor wired stand alone meter. Installation version, fixed sensor unit to build in to TT. Skip to primary content. Skip to secondary content. Menu Toggle. Drone-in-a-box systems have been a focus of interest  for militaries as a less expensive and less dangerous alternative to human-led communications, resupply, and offensive missions.
In February the US Marine Corps ran a drone-in-a-box trial to test the viability of using both autonomous helicopters and smaller drones to resupply front-line troops without the need for a human pilot. Autonomous, drone-in-a-box systems have been used to survey the progress  of construction and capture visuals during the construction of the Gulf Port in Haifa, Israel.
InCERTUS  Port Automation signed an agreement  to deploy the autonomous drone-in-a-box solution to enhance port security, becoming the first company in the sector to embrace the technology. Drone-in-a-box technologies have been used to bolster security in commercial and military applications automatically deploying when alarms are tripped and providing close-up footage or carrying out scheduled patrols.
Additionally, companies have used drone-in-a-box technologies to support security at large events . Companies have also embraced drone-in-a-box technology to survey farms and golf courses  by using multispectral cameras that can be tuned to respond to specific light wavelengths, including some infrared. Using these cameras fixed on drone-in-a-box systems, drones can detect health-related changes in vegetation.
Drone-in-a-box solutions are used today to support operations at power plants, capturing aerial video and data to be streamed to personnel in real time.
In Israel-based Percepto partnered with Italian electricity and gas provider Enel to LP) their on-site autonomous drone system at the Torrevaldaliga Nord power plant.
