Microchip spec sheet confusion
I needed to check a spec sheet for a Microchip microprocessor recently and was surprised how confusing the writing was. I'm posting this video to shed light on a problem that is wasting a huge amount of engineering time - and a providing a path to how this can be corrected.
Just after putting the video together I needed to check cap values for the CPU crystal and found that description virtually unintelligible as well.
I like Microchip products but I wish they would get it together with the docs.

Pull wire R/C connection

I go over some techniques for attaching a thin pull wire between servos and R/C control surfaces. I show a clean strong method that requires no adhesives or solder and is detachable for repairs. In one version I replaced the wire link with a screw thru the loop but that created hysteresis so I recommend the wire links shown. Here's how to get the wire length right. 1) Twist one end first and at...

    Instead of heating up a razor seems to me to be easier to use a small drill bit to get it started and then use a small saw blade. Or simply use the drill and then cut with the blade. I will use your idea but change it slightly. Going to order Deck loops and screw them with a nut and bolt to the sides on the outside. This way I only need to drill 2 holes each . Just a different way of doing it. Your way doesn't require buying any hardware Thanks for the video

    Tried FP in PHP. Immutable variables are not possible in php so at least I follow the rule not to change a variable unless it's a loop control variable. PHP has no local functions like C# has but it's possible to locally define an anonymous function and assign it to a functional variable. PHP has some built-in FP support like anonymous functions that can passed to functions like array_map, array_reduce, array_walk, etc. so these functions in combination with anonymous functions can be used to eliminate loops.

      FrSky G-RX6 due to altimeter. I get between 20-25m launches. I put the antennas inside the wing in a V formation. Stay away from the analogue servos - go digital. I'm using the Emax ES-9051 now with the bottom removed to make it fit. I run 1S for simplicity. I converted to music wire pull-spring controls - more durable. I probably have 500 flights or so and it's still in excellent condition.

    I have a Longshot 3 - love it. I wish I could get it to balance with no added nose weight. I have spring pull set ups too. I used Spectra/Spiderwire fishing line - virtually weightless. Can you/do you detach your control horns when not flying so the springs don't get memory. Propably needless. Where are you from?
