Fantastic, I love how when it dies and the blade begins to spin down, it chimes at the end like the bell of a church signifying it's now resting in Electrical component heaven.
You need to still have the plug on, so when they plug it in and turn it on ( they always will do that unless it is truly in pieces externally) it will smoke a little and then the plug fuse will stop the fun. Act clueless and say " You broke it!" then as well. New one sadly will be made with a junk motor, not the proper copper wire but the nasty CCA wire they all use in current models. Same poor bearings though, the old one just needed a few pounds of bearings and gears to fix it, but being an off brand with house label ( probably a Ryobi model in any case) it might have been hard to get.
+SeanBZA Actually you can get some bearings just about anywhere (especially on eBay), but gears (especially for something manufactured specifically for the department stores) are next to unobtainable (except if you know someone who can do fine metalworking or have a CNC handy of course).....
Assembled saw: Nought to pop in 62 seconds Max power before malfunction is 2.293 W Peak popping current is 27 Amps at 411 Volts (thus an apparent popping power of 11.097 VA (Meter shows 9.615 W)) Cause of failure: Field winding meltdown. (I'm surprised the brushes didn't fail o,O ) "Repaired" saw (#1): Nought to pop in 36 seconds Max power before malfunction is 1.550 W Peak popping current is 19 Amps at 165 Volts (thus an apparent popping power of 3.135 VA (Meter shows 2.976 W)) Cause of failure: Brush flash over resulting in meltdown of input cable solder. "Repaired" saw (#2): Nought to pop in 36 seconds Max power before malfunction is 970 W (that's when flames started shooting out) Peak popping current is 63 Amps at 111 Volts (thus an apparent popping power of 6.993 VA (Meter shows 6.824 W)) Cause of failure: Brush flash over resulting in burnout. "Burnt out saw (finishing it off): Nought to pop in 46 seconds Max power before malfunction is 0 W (it was already malfunctioning at the start) Peak popping current is 61 Amps at 32 Volts (thus an apparent popping power of 1.952 VA (Meter shows 2.038 W)) Cause of failure: Probably thorough meltdown. P.S.: So did the saw only spin in the second and third experiment because of the remaining magnetization of the field winding? P.P.S.: I just saw the comment about this, so you turned the thing into a reverse induction motor. Funny. :D
If you just multiply Volts and Amperes you get VA, not Watts. For measuring Watts, you need to multiply VA with phase angle as well, that is what this meter does and than displays it.
I'm laughing right now, over him still trying to juice this thing as its burning in flames, and all I can think of is the Simpsons meme "Stop , Stop, he's already dead!"
I have never before been convinced that a saw blade was going to go into hyperspace, and come right through the screen and slice off an appendage. Bravo!
You, sir, are the Ramsay Bolton of Alternating Current! Was one of your ancestors responsible for Tesla's lab burning down? Nice torture test. I particularly enjoyed your insistence on ensuring that each and every conductor in the system receive a complete meltdown. Half way through, I nearly had a panic attack when I imagined a toddler walking down the passageway! Na, couldn't happen, the kid would be taken out by the tesla coil in the garden!
Unsuspecting individual - "So, how many amps does that saw draw?" Andy - ".......all of them, mate. It draws all of the amps." Unsuspecting individual - 'confused look' Andy - 'lunatic laughter'
This is the rated power use of the saw. this is the maximum current and power it can use, and THIS is where PhotonicInduction gets a bit stupid with his toys.

just loveley to watch, its almost impossible to kill good old stuff, quality made 😉 like the jet engine here, the fan in the front makes a nice jet flame !
+Klaufmann Who doesn't? :) ...but no, that type of motor has Mains AC on it and it runs fine. As long as the field windings switches polarity with the armature. (North and South swaps sides when referenced to actual space as the armature spins. On DC, it doesn't.) ...then again, he could have easily rewound the field coils with #10AWG THHN.
Yes, but universal motors also run on DC, so permanent magnets would act like field windings on DC voltage. On Ac it only runs, if stator and rotor get the same AC current, so this wouldn't work with permanent magnets, as they don't change polarity.
I feel like this puny wood fence is not a valid protection for this evil science. Imagine sitting on the other side and suddenly a sawblade with 10000 rpm comes shreeking thru like in a scene from doom eternal.
Its interesting that the motor speed tanks once the fire cyclone starts spewing out the back of the motor housing. The heat and light takes energy from the rotational energy in the motor
I have an idea for you man ... you should get a huge lumber saw, like the hugest blade you could find, and see how fast you could get it to spin before it broke off and flew into a wall or something ^^ That would be so goddang funny xD
@ 6:42 normally when you hear this sound you automatically stop within 2 sec. because you know its bad, but you kept going and my toes were curling down , then i realized i was watching Until it Pops
Awesome. Could you achieve more of a fireworks show if you ramped up the current quickly, rather than stepping it up slowly, which allows the parts to heat up (heat being the ultimate cause of failure..?)
question about your power, 50Hz? the flickering on your watt meter thinger makes it a bit tricky to read in a video, its a pretty common problem, So my question is , are there any practical ways you could manipulate the power, like for exsample adjusting the cycles or filtering it some how... or is it just easier to find a camera that can be set for 50hz power grids, I have the same problem sometimes.. im looking for the most complicated way possible to mess with the situation! thanks for your great videos by the way, Power to ya :)
Hey Photonicinduction, did anything become of the medical laser you acquired? I think the last i saw of it you were planning to bump up the size of the lamp a bit, but i dont think there was a followup to it. Anyway, cheers, great and entertaining video. you never disappoint.
