Channel Munch Welcome back to the shop! We got this punt about the autopsy table. I've spent a couple half dozen minutes cleaning up. That's about enough for me. It gets under your nails.

It's the ambivalence of humaning. There's always two sides to every story. Do I want to do it? Do I Not want to do it. You just give in sometimes.

I set the stinking while I was sweeping, you know I I Like poking tinternets with a stick and seeing what kind of hornets fart out. So I would appreciate it If you do it. do it for old. Gill here.

do it for Old Uncle Bumble If you could unsubscribe, not for no reason I'll get I'll ask you at some point to re-subscribe but we're gonna do a tear down to this guy and then we'll do probably I got uh cooking Bumble Forks video in the can and then we're gonna do a companion to this guy and I'll ask you to resubscribe then. but I just want to see what happens I haven't seen anyone on the YouTube making videos who asks you to unsubscribe and it's not. There is not a contractual obligation. You know when people unsubscribe, generally they treat it like a departures.

Lounge At the airport, they have to announce their departure. Just go ahead and unsubscribe. please. right now please.

And then we'll see what happens, because why not? I dropped One ancillary benefit to sweeping up. you can find your screws. the glass fiber reinforced Pa6 quite thick new mold, some hand polished areas. Looks like some cut marks up in here from the Milling cutter of the mold itself.

Oddly enough, the back end doesn't feel like the same material. It's certainly not as thick or maybe the wall thickness is as thick, but there's no gusseting that could be. Now we're going to zoom in on the inwards, not all that much to it. We have a die cast motor housing front end just a typical brushed motor.

What was that? Oh, there's a seal in there, so that's the sealed shaft. There's also a seal here on the back side of the bearing. keep the juice where it belongs. Again, with the neatly swept floor.

normally. I'm working against myself, so this is brilliant. Way better than the Milwaukee because you can connect it to the power grid now. it won't charge the battery.

However, if the battery is dead, you can just plug it in. which I Love if Milwaukee would have done that and such a simple thing. Really? Because you can have an external power supply that does all your rectification. Takes the angry Pixies dancing to and fro from the wall turns it into nice lazy DC.

But that's all. Uh, a separate module. No big deal, you don't have to build it right into here. What we have is DC power going into this would be parallel with the battery terminal going into the brain box.

Nice big Skookum wires. they may be aluminum, the copper cladding being that they're so big. foreign. ER light the switch where the rubber meets the load.

This is where the 200-pound gorilla goes hammering on like a monkey at the zoo. Nice snappy snap action and it is a 16 amp 36 volt rated DC switch. Feels good and this is interesting. There's a little condom on there and it's glued actually, but it says not one and zero.

Focus you thank you says on an ORF Isn't that nice English The lingua Frank of our age. you ever get worried about the state of the world Thank you Lucky Stars or your Saturn Alia depending on your Sinister disposition that you know you go to some foreign country, you say Cuba They ain't bootlegging Russian movies. There's a reason that English is the lingua Franca of the H and uh might be a blessing in disguise to be a native English Speaker I Say that as an outsider of course as a non-native English Speaker: there's a brain box. We got some solastic all over the wires already breaking.

You can see well, there's a couple things with make you suspect it's a lower grade than say Milwaukee or the Walter On the back side, there's some additional traces soldered up built up for ostensibly ampacity for being able to carry extra current. You see those those guys there? That's kind of an odd thing. Those are nicely nipped off, the wires protruding through, nicely soldered and nipped off. We got a half Bridge a couple two, two little mosfets there of the half bridge and then the brain box itself.

the microcontroller. I'm afraid my regular cameraman's on strike that were I have a little overshoot. Oh fine. motor less she brand with some flux rings, extra magnetism around the motor itself brushed DC Big old D shaft on there integral bearing in the front.

Not really all that much different than what you'd expect. This is interesting. There's not a die cast part and they're machined. It's a sand cast so they would have had to make a mold with that and then sand cast it.

You can see the texturized of the sand and then machined on the shiny bits. I Got the diaper rash cream afterwards. It appears to be thermal compound thermal transfer compound. It's either a diode or a temperature.

Well, a temperature dependent diode or a thermocouple. It's likely a diode I Bet you if we look in there, it's probably just a light emitting diode. They have a reverse bias direct bias. The warmer it is, the lower their resistance.

so you can get in. LEDs If you don't control the amperage going into them, you can have a thermal runaway and they get to such a low resistance that they just blow out. That's if you're trying to get light out of it. You can also do the reverse because if you want to measure the resistance, you can coincide that with the temperature if I could get in there without springing a leak and it'd be just fantastic is come at it from the back side.

Nothing there, nothing there. Not Diode must be a thermocouple. Let's see. this should be voltage if it is a thermocouple.

uses the difference in potential the two dissimilar metals to put out some millivolts which it is not doing. Hmm. some old form of devilry. So yeah, appears to be a Meester you want to buy my sister her name is Thai Mister Just a Kiss oh Callister towel neck that ain't right.

Sure enough, hotter it gets, the lower the resistance. It's a thermistor. What? You stink Half a turn fart Let the Smoke Out I factory deleted the back end. It was bite me.

It was spring-loaded and kept a bad juju. I got five extra horsepower out of the cork stuffer. Now as I said fart Let the Smoke Out yeah Oh, it seemed quite simple. Oh oh there.

I had to turn it. You got to be smarter than the pump. Thanks! Louder than the Ladies Auxiliary On Chardonnay night, have another Shard and a dirt merge. Okay, it's not as heavy duty as the Milwaukee but it claims to be 325 gallons per hour.

The Milwaukee is 460 I believe and I actually bought three of the Milwaukee's because the brain box fries out of them you recall I took the brain box out of one of them that fried. Just put the kachunka chunk switch worked fine, then you know Weinstein Said make something only as complicated as it needs to be, but no more. So okay. get a listen to this.

Freewheel Speed. Put some lube in there. You got to cut the tube. uh, overheat it or over speed.

It knew it's somehow new. Now the hazard part for the 100 bucks gives you a whole bunch of accoutrement. look at this collapse free suction hose what with the Skookum fact and wire in betwixture between the Milwaukee 250 kanaki stand. copex.

Your mileage may vary, but they're 250 bucks a pop. We'll put the inlet on the inlet and they got the Mil-spec three-pin big bore power connector and it locks in. Nice. Wow.

Okay, let's give that a try now. I wonder if it charges? It's smart. Very clever mechanically. You cannot put the battery in at the same time.

I was like yeah, that's that's. pretty smart. That's pretty smart, cheap and effective protection. Now the fun part.

We got the little miss all set up to go from suck to blow. Got a pressure gauge here. vacuum gauge actually on the inlet side. We're gonna see how long it takes for it to pump out 20 liters from the hazard for bucket is dirt.

Also, there is a decibel meter in a or C waited contact as I ineffectually try to actuate my fingers. Okay I already felt the bucket. Let's try this again. A lot quieter when it's actually pumping something.

we're at negative five inches of mercury. Nice stops on its own. That's a good feature. It must monitor.

It's got to be monitoring the amperage going to the motor. The amperage must drop down because that's far too quick for the temperature to rise. We're going to see how much suction we can actually draw. Oh come on man, it's dead already.

Oh, it's telling us it's not happy. Of course it's not. Uh, let's take the battery up. Oh me, you gotta be me.

It appears the operation was a success. The patient didn't survive however is dead I don't know I'll get her onto the healing bench. Everybody's favorite. Your balls deep in a greasy Cesspool rusty old crop start pumping and then quits your tool quits on you did does LED indicator was blinking and now nasink batteries charged will not does not nothing it does have I mean it got wet.

it is a pump. Did it get submerged? No and something tells me you're probably I Haven't read the manual, but you're probably not supposed to take it apart before you run. it seems in my haste, yeah, not seem, no, seems about it I up I Crushed this little sense wire. however I don't believe I broke it and hmm.

well the higher the higher the resistance, the cooler it would think it is. I Also there's the the blinking LED pinch that wire too. just using the Diagnostics internal to the tool that is the LED indicator. We should see a little blip or something when we connect nothing.

Let's see where we get battery voltage. Okay, we got 20 volts at the switch. That's battery voltage at the switch. Huh? Glitchy.

See if that indicator does anything. No, it does not. A wonky connection at the tools are getting smarter all the time. Smarter isn't better.

Smarter doesn't make it better. What would be better is if it told you via dust blinking lights what the conjunction and the malfunction was Why didn't it spit out a code? It knows there's something wrong. Why wouldn't it say beep? You know you just look. four long flashes.

Yeah. broke that right in, right in. And that way if you don't see it flashing, you know that the computers blown up. If you're going to go smart, go stupid smart.

Also, we could be privy to some very clever marketing as witnessed by the Rygal Scopes where they leaked or someone leaked to get out of jail code. So you could jailbreak your oscilloscope into a much higher powered oscilloscope just by inputting this code. And that sold so many Rigal scopes. It was unbelievable.

So what you do in one of these as you make a play a little game. Or you know you, you do the left, left, right, right by and and it pulses. Or it does this. or it does that, or it.

it plays a song. It plays a song with the motor. Huh? Get the pump set up Now with the three ampere hour battery I Forgot to hit record unfortunately. but two minutes in, you'll fully charge three ampere hour battery.

Just the Indies as Condition it's going to encounter pumping into a bucket same height, no head, just to see one how long it lasts. Two if you'll be able to empty out your hot tub with it Time figure: 25 minutes I give or take Five gallons a minute, 125 gallons, Four 500 liters you get out of a charge, three point, or three ampere hour battery fully charged. you'll get 500 liters out of it. Best case scenario: of course you could do more, but you need a 800 foot length.

The hose, down a mountain embankment, a polo water siphon the water out. Yeah, you count on 125 gallons roughly. If you're discharged in a hot tub or something like that. we're going to approximate the pump curve here by restricting the inlet, watching the gauge, restricting the outlet, watching the gauge.

That's pretty much it. Things says it'll do 45 feet ahead at 0.433 pounds per square inch per foot of head. That'll give us, uh, almost 100. PSI Oh okay, let's see.

Oh for the lava. so reliably that'll draw about 15 inches of mercury. We had 20 psi. what's going on I would say I had a malfunction of multiplication versus Division I should have multiplied that by 4.33 not divided which would give us 20 psi.

So that's about right. Well, the only thing worse than not having the tool what for doing the job is having a tool. It's not reliable. you don't know if it's a sub.

I know you're tripping over your wallet. Try and replace your Milwaukee one of these, but just hold off I Gotta I got a runner a little bit before I can give you the all clear something. Well, that might have been my fault.
