The main enckosure requires a power supply to allow the hubs to power all the tuners at the same time, the step down coverter allows a wide DC input range to be regulated down to the 5V which is then avaialble via 2 USB-A female sockets. The clamp is designed to be as close of possible to the top of the enclosure, so the notch is necessary to feed the cables. The coupler should be positioned in the clamp so that it is flush to the outside bottom of the main electronics enclosure.Ī notch exists on the top that allows the cables from the power jack to connect to the power supply module. Threaded inserts are used on one half of the clamp, an M3x7 cap head screw is used to tighten the clamp to a force that prevents the coupler moving. The cradle part helps keep the USB hubs in the correct location, as the wiring is completed they may move around and become difficult to work with, so the cradle stops these problems from occuring and provide a controlled way to route cables.Īs I used USB 3 hubs in the design, I wanted to make sure that the path from the hubs back to the host is at USB 3 speeds, I was unable to find a reasonably priced panel mount connector so used a USB 3 to USB C "coupler", and using a printed clamp that securely holds the coupler. The electronics enclosure ties the whole system together, it consists of a number of other sub assemblies to provide a robust and easy to connect system. The previous image shows a tuner enclosure with 3 tuners and 2 blanks, in the UK I am only interested in 6 MUXES, therefore I opted in my configuration to equally space the tuners across 2 enclosures rather than 5 in one enclosure and a final enclosure with 1 tuner and 4 blanks, this is a personal preference and you can choose to use any spacing your desire.Īn M3 threaded insert is located in each corner of the bottom enclosure part to allow a strong connection to the top case. There is sufficent space inside each enclosure to coil the cables into small enough stubs to pass through just enough cable to connect the tuners to the hubs.Įach enclosure includes a hole either side to allow cables to enter and exit the enclosure, this allows enclosures to be butted up to each other and have the actual USB connectivity completely hidden.Įach tuner is held firmly in place by an appropriately sized compartment and lips are used to ensure that the tuners stay inside the enclosure, so there is no worry of pulling the system apart by tugging on a wire!įor any position that is not to be populated, a "tuner blank" model is provided that matches the dimensions of the real tiner (it is not exactly the same, it has been reduced in size in places to prevent filament waste). The Tuner EnclosureĮach tuner enclosure can hold 5 Xbox One tuners, a tuner "blank" is provided if not all slots are required. The system was designed to allow the system to be neatly packaged in an attractive way and to prevent a neverending cycle of cable spaghetti, the tuners obviously need to accept a feed from the antenna, but apart from that a single 5.5mm by 2.5mm power jack to provide power to the USB hubs and a single USB-C connector to connect the hubs to the main PC. There are no specific requirements for printing (support free!), it should be obvious when loading the STL files into your slicer as to the correct orientation that the parts should be printed in. Using PETG filament or better should ensure that structural integrity is maintained. It is recommended that the files are printed using a filament that is not likely to soften under heat. Here in the UK the major channels are broadcast on 6 MUXES, because this number is reasonably low, we can use a tuner per mux and pre-tune each tuner to a specific mux, the upside of this is that when a TV channel is requested, the tuning is already completed and the stream can be provided very quickly.Īnother benefit of operating a system in this manner is that there is no limitation on the number of or combination of channels that can be recorded at the same time, every station could technically be recorded at the same time. This repositiry contains the STL files for printing a set of enclosures that will house multiple Xbox One tuners and provide a convenient means of easily connecting these to a host system.
