  1. That was very helpful, thanks for taking the time. I'm about to install my first linear actuator and this has clarified a lot. Thanks!

  2. This was quite informative. One quick editing criticism – it's generally not a good idea to have background music behind information-dense speaking, especially when you aren't professionally miked. In other words, you were a bit harder to hear due to echo in the room, so adding background music to that made it even more difficult – unnecessarily. Thankfully, you didn't have the music going for long…but why have it at all?

  3. One of my hobbies is boat building, and after seeing this, I just might use a linear actuator to engage and dis-engage the drive system on my next project. It would be awesome to engage drive (or reverse) by pressing a button. Might use them for other things too. Thanks for directing my attention to these.

  4. Reading post below are asking a lot of good questions. The length of wire and the amount of current determines the size of gauge of wire to use safely. There are many charts online to help with the size of AWG gauge. Remember as well, that a device, if rated for 2.5 amps, there is an inrush of current when first turn on, due to copper coils in the motor are cold, more current because less resistance. So, 2.5 amps maybe 3.0 amps for a second or less. This also help with sizing a fuse for circuit protection. Using a high end digital multi meter (DMM) like a Fluke 87 type 5, will measure 15 amps inside the meter with the newer fuses. Using two actuators in parallel adds to the amperage, so 2.5 + 2.5 = 5 amps, but add cold start current by measurement (Digital amp clamps are good & cheap) is the best way or guess using smaller fuses under a dead load. The dead load increases amperage requirements to start a heavier load to get moving. The "Speed Switch" is more likely a (PWM) pulse width modulation type. So these are a duty cycle type, example; 50% duty cycle is on half of the time & on half of the time, therefore you will expect half speed of the motor. Just note, the total amps required for your device, must be determined before you order the PWM speed controller so it does not fail due to higher amperage than it's rating. To be safe, purchase one with twice the current rating of the actuators / devices being used assembled in a real word project. Test, know, don't guess! The fuse is to protect the wires in the circuit and not the device. The device is designed to be change, while the harness is not.
    And for Harold Buford, people by habit, create tic's in there speak. I know a guy that says "On There" at the end of each sentence. Ah, Uh, Ums, You know…are all habits, a little annoying but it will not kill you. No ones perfect. Hopes this helps our fellow creator, inventors and wood-workers! A very tall eye lady eye doctor told me, that her husband & her both had counters in their house adjustable with actuators…it cost $14k extra. But how much is back surgery?

  5. Special request. Please say uh and um more through out your video. 2,000 uhs and ums are not enough!!! For fucks sake!!!!

  6. Thanks for the links I have been looking into this because I need a different desk set up. I want to take the top off my desk and add these to it so it looks just like my desk does now when down but then raise it when I want to. Do these pick that much weight or are they rated above their actual real working situation. I have prolly 150 lbs altogether with iMac and second screen plus the top is solid wood. What are your thoughts on the weight lifting capabilities?

  7. Due to needing to run fairly long runs of wire (30-60 linear ft) I was curious what gage of wire does that take? I am assuming 18 gage but do not know for sure.

  8. Very informative, thanks for sharing. I want to build a sewing table for my wife and be able to have the sewing machine drop down out of sight and raise up to position. This video opened my eyes and really helped me understand how I’ll be able to make it happen. Thanks again, very well done!
