ExpressLRS FAA Remote ID Proof of Concept CapnBry 2022-08-06 | ExpressLRS 3.1? Details will come as things get finalized. This is currently over BluetoothLE (BLE) and wifi beacon, ASTM F3411-19, but hopefully can reach ASTM F3586-22 compliance.EDIT: unfortunately it is unlikely that ExpressLRS can ever be compliant, as it is too easy to tamper with and will not meet the requirements. I'm not sure I'll continue to pursue this but it does mean that the same hardware can make a compliant system if it was sealed with the GPS.
ExpressLRS 3.0 Packet Modes Explained CapnBry 2022-07-09 | ExpressLRS 3.0 adds 150% more OTA modes over 2.x, and you want to know, "What rate do I use?".

ExpressLRS FLRC Range Test 500Hz 100mW CapnBry 2022-04-14 | 2.4GHz ExpressLRS 500Hz 100mW FLRC beating my expectations on range compared to my earlier experience with TBS Tracer 250Hz at 250mW. The range is much greater than shown in the video, the model loses LOS and even the 800mW VTX goes out completely.Would this me more interesting or fun to watch if I had provided commentary over it?

Sky03O vs EV800D Reception Comparison CapnBry 2020-08-21 | The reception on my Skyzone Sky03O isn't very good compared to my old Eachine EV800D goggles. The ergonomics are so much better and the picture is so clear and bright, but that's not really worth much if you can't see where you're flying. I decided to do a quick comparison of the reception and swap the antennas between two flights to see how they hold up against each other.The Eachine with 2x cheap omni antennas was at least as good as the Skyzones with more expensive antennas. Swap the two so the Eachine has the good antennas and it blows the Skyzones out of the water. Care was taken so that the sideways omni was pointed so its null was 90 degrees to the area of worst reception and the patch was pointed directly at the area of worst reception.The DVR footage was only scaled for size, the color is very different between them. The Skyzone footage with the two ominis was stretched 1% to make up for lost frames (it also lost 3 frames when it had the good antennas)Antennas (all RHCP):TrueRC Singularity - this thing kicks butt, and the tiny version on the quad is even betterMenaceRC PicoPatch - also really good with a pretty wide FOVFoxeer Lollipop V3 - Not a bad omni and a good bargain but inconsistent performance from antenna to antennaEachine Cloverleaf - This one came with the Eachine EV800DMusic: Subway Dreams by Dan Henig from the Youtube Music Library

80 Zones on the LG 55LH90 CapnBry 2010-01-13 | This is my test of the LG 55LH90 to count the number of local-dimming zones the LCD has. There are 80 arranged 8 high and 10 wide and you can count them too. The camera is set up way off axis so you can see the backlight blooming in the diffuser. As I move the block around the screen note the larger fuzzy area that lights up, as the block crosses to a different zone you'll see two zones light up at once then the other zone turn off as the block leaves. When the block gets to the top of the screen you'll see it get pretty dim, this is because the zone dims as most the block has left the screen.
