Bullseye LNB Tripod Mount

prusaprinters

<p>Use this for mounting your <a href="https://othernet.is/products/bullseye-10-khz-ultra-high-stability-universal-lnb">Bullseye LNB</a> to a tripod-style mount. I use this for my <a href="https://github.com/Othernet-Project/Dreamcatcher">Dreamcatcher</a> station where I don't need a full dish, just the LNB pointed straight to the satellite. The tripod-style mount works great because you can get cheap and massively-available ball mounts and clamps.</p><p>Features:</p><ul><li>Bolts can be adjusted from the top so that skew can be adjusted without having to change az/el</li><li>The attachment point for the tripod has a stop so that it does not get over-tightened; this is important because the shell of the LNB can get cracked with pretty minimal force (guess how I know…)</li></ul><p>BOM:</p><ul><li>1x printed “top.stl” in PETG or similar outside-friendly material</li><li>1x printed “bottom.stl” in PETG or similar outside-friendly material</li><li>2x bolts, can be between M3x12 to M3x16; I used socket head, but others should work too</li></ul><p>Instructions:</p><ol><li>Print both sides.&nbsp;</li><li>Use warmed screws or taps to thread the threads for the 2 screws and the tripod mount</li><li>Place the LMB into the mount and screw the two halves together with M3 screws; the tolerance should be just right, though if you find that it's a bit loose, just add some vinyl electrical tape on the inside of the mount</li><li>Install the LNB to the mount and aim; loosen the M3 screws and rotate the LNB as required in order to set the skew properly</li></ol><p>Aiming procedure with a dreamcatcher: the board has a built-in LED that indicates frames received; aim to maximize this signal received. Once the general azimuth and elevation (left/right, up/down) as been set, open the dreamcatcher's webpage and read the signal received. Adjust the skew to maximize the signal. If you find that even after this frames are not consistently being received, you may need to add a horn on the end of your bullseye to maximize the signal received – refer to the othernet forums for instructions on this.</p><p>&nbsp;</p>
