When I was offered the opportunity to beta test an upcoming robotic arm from Tormach, I knew exactly what I wanted to do with it. CNC chainsaws baybeeeeee. Aside from being fundamentally awesome, it is a very interesting software problem. Since I didn't have to build the arm I was able to focus the project and the video on the software challenges of making something like this work. Thank goodness I didn't have to build the arm because the software almost killed me. I can imagine all kinds of next steps for this creation like machining textures with the chainsaw or cutting topiaries. I hope you like it!

    awesome, very interesting, I guess you know that the chains have to be sharpened frequently, and that you don't have to apply too much force when cutting, if it doesn't get too hot, it must be incredibly difficult to find the point of it all.

    Hey, I have an idea for something you can make. I have a vintage Motorola car phone in my 88 Cadillac and I am trying to figure out a way to convert it to Bluetooth so that when my cell phone rings it gets sent to the car phone in the center console and I can receive and make phone calls on the factory brick phone. I can't find anything online in terms of forums, diagrams, or instructional videos. I think that would be a cool project that would get tons of views.

    FYI pretty much throughout the video, the chain was suuuuuuper loose. Also, I didn't look closely at your conversion, but bar and chain oil is important when cutting wood with a chainsaw. Also, your chain doesn't appear to have any anti-kickback features. I prefer going without the safety features anyway, but that tooth you pointed out is simply a raker (aka depth gauge). What could be wrong if your chain isn't dull, is that the rakers may not have been filed down low enough the last time the chain was sharpened (The height on the raker determines how much material the blade part sees at once.)

    Hey Stuff Made Here, if you need to compute more faster take a look on CUDA (its basically C++ langage). Deppending of your graphic card you can compute all you need more or less faster. (I succed to pass from ~8k year computation in Node to 1day and half with CUDA). I'm a big fan of your work, please continue.

    I know that it's irrelevant now, but I have a suggestion to solve the gradient ascend problem. If you choose just one random starting dot and use gradient ascend to find the extrema, its highly possible to get a local extrema, but given that the robot will be cutting the wood with a chainsaw ,which means that the bumps and protrusions will be relatively big, u can maybe use a gridlike aproach(e.g. 1cm between dots) and use gradient ascend multiple times to find the highest point. Love the videos.

    I don’t think your warning label (or the red flashing light, for that matter) is really going to protect you from being slashed by the saw blade. The kill button is a good idea though.

    Whenever we do a gradient descent and we're worried about getting stuck in a local maximum or minimum, we can try the _simulated annealing_ technique to reduce this problem. I'd recommend looking at a real author's description of this technique -- but in essence, we move all over the search space very quickly at the start, making huge jumps to avoid missing the absolute min/max. Then, as the simulation progresses, we "cool down" our discovery heuristic to only look at areas that are sufficiently close to our current location. This lets us hone in on the true correct min/max value; eventually, the simulation "cools to zero" and we no longer search, assuming where we have landed must be our target.

      Couldn't have said it any better! Something tells me he definitely attempted this at some point (simulated annealing is likely one of the first search results in getting around local maxima/minima in gradient descent) but eventually abandoned the idea for some reason.
