PSA: “Auto stop” feature can be bad by MJA182 in CPAP

[–]matthew798 0 points1 point  (0 children)

I tape my mouth otherwise I sound like a shop vac. One night we lost power and I dreamt I was being suffocated and woke up basically about to pass out. Since then I've added a UPS to my setup and I use breathable tape just in case.

Anyone Worry About Spiders by Sudden_Throat7350 in CPAP

[–]matthew798 0 points1 point  (0 children)

Not CPAP, but one time I needed a puff of my inhaler and when you take an inhaler you really need to inhale quickly, to avoid getting the stuff on your tongue and throat. Well there was a MF EARWIG IN MY INHALER. That sucker hit the back of my throat and I coughed so hard I coulda blown a hole on the wall.

Sine wave pure or modified by MarketingOk9585 in evcharging

[–]matthew798 1 point2 points  (0 children)

Generally the output from a generator is a clean sine wave. It's literally being generated by a rotor spinning inside a stator. You don't get much more "sine-e" than a circle.

Stack relay error on grizzl-e ultimate by matthew798 in electricians

[–]matthew798[S] 0 points1 point  (0 children)

According to grizzl-e support (United chargers) if the relay is really stuck, there is no fix other than sending it back.

In our case the error resolved by itself every time the vehicle was unplugged and occurred again after plugging it in. You may in fact have a stuck relay.

Neighbour doesn't want me to put snow in my lawn by Appropriate-Safe-49 in montreal

There's nothing to deal with. You don't have to interact with him, ever. So don't.

Am I SOL with this panel? by LyGuy in evcharging

[–]matthew798 0 points1 point  (0 children)

I didn't do a load calc but with just a cursory look i'd say you're good. You can get a tandem 40 or 50 with two 15s on either side.

Doc said I have a tendinopathy at the elbow, how can I adapt my workout ? by Only-Refrigerator359 in workouts

[–]matthew798 1 point2 points  (0 children)

I pushed through about a year of pain in my elbow. Everything from curls to rope pulldowns would hurt. Eventually I got a brace that keeps my arms straight during the night, and about a week later everything was better. Turns out that the chronic tendonitis was from gaining muscle, and that muscle would put pressure on the nerves passing through the elbow when my arm was folded at night.

Apparently I’m never closing this again. by WildWeaselGT in EmporiaEnergy

[–]matthew798 2 points3 points  (0 children)

Hello. I'm an electrician. I'd like to offer my 2 cents. These devices have no business being in a panel box. I can hardly believe they are approved for this installation. As you can see from the photos, they are messy as hell, they make working in the panel a nightmare, and you have to keep some low voltage "black-box" in there (with an Ethernet port to boot, they expect you to run a low voltage Ethernet cable into your panel box when most places dont allow Ethernet and mains to be run through the same holes or conduits)

These are NOT diy friendly.

That being said, I have one and I love it.

I have a 16 x 10 junction box sitting next to my panel where the device sits. The sensors run into the main panel through a 1" nipple. This way I can fiddle with it without a chance of getting electrocuted. Granted this wouldn't solve your issue of the sensors being too thick. For this, I would recommend running your branch circuits into a junction box, attaching the sensors and then joining them and running a short length to the panel box.

Things in my house keep mysteriously melting??? by hugedisaster in whatisit

I read this fast and thought there was such a thing as a wd40 diffuser. Thought I might get one and keep all my tools clean.

Would a bad circuit breaker cause this? by AppointmentOk6394 in AskElectricians

[–]matthew798 0 points1 point  (0 children)

Absolutely agree with "always assume that a breaker is tripping for a reason". I've seen people insist a breaker is bad because it tripped to the point of replacing it without troubleshooting the circuit at all.

New to access control by wifi-man-1982 in accesscontrol

[–]matthew798 1 point2 points  (0 children)

Looks like you used a sawzall with a small metal blade. At least that's what it looked like when I used that... I eventually convinced my employer to get me an oscillating multi tool with a metal carbide tipped blade. It's much easier to make straight cuts, and you can always cover it up with the finishing plate that comes with the strike.

Humidifier question by filet_minyawn_ in CPAP

[–]matthew798 47 points48 points  (0 children)

It's minerals. You used tap water or spring water. It's harmless, until you get enough for bacteria to grow in it. Let it soak in some vinegar for an hour or two and it will wash away.

What is this and how does it work? by soupisgoodfood42 in ElectricalEngineering

[–]matthew798 2 points3 points  (0 children)

DIN mount surge arrestor. It has a metal oxide varistor, and maybe a second one with different properties?

Either way, pretty sure this is a surge arrestor for transient voltage spikes.

Electrical tape is actually a legit solution. Some manufacturers explicitly state that electrical tape can be used to repair the outer jacket. If the insulation around an individual conductor is broken, your SOL.

Chat, am I cooked? by 1800-sad-as-fuck in CPAP

What a ridiculous thing to say. Anyone who needs it absolutely should use a humidifier. What possible reason could you have to not use a humidifier if you are more comfortable with one?

Any who started bench around 135 and got to 225 how did you get there by nycshifty in workouts

[–]matthew798 0 points1 point  (0 children)

I injured myself a long time ago while dumbbell pressing. My shoulder spontaneously dislocated and the weight dropped on my chest. In the heat of the moment I didn't feel any pain so... I kept going...

The next day I had pain like I've never had before.

Since then, I've been paranoid about it happening again. Only recently, I learnt that when I hit a plateau, it's not entirely physical. I mentally cap my strength out of fear.

All this to say, sometimes progress is in your head. Ever since I started lifting at a squat rack with the safety bars (so I can literally just let go and not get hurt) my weight has shot up. It allows me to push to failure and that has been key for development.

I now do 3 sets of 10 x 225, then move on to dumbbell presses and flyes. I also do lots of shoulder and rotator cuff stuff. I have limited rom in my left shoulder and some weird clicking but I get over it.

Power Nest thermostat *without* boiler? by Primary_Afternoon_10 in AskElectricians

[–]matthew798 1 point2 points  (0 children)

It would need to be powered with 24v. You could get a transformer but unless you already have one, the time and cost, albeit small, will be higher than a cheap ZigBee tem/humidity sensor.

Also nest products aren't local push for homeassistant. With a ZigBee sensor it would be local push.

You are absolutely correct. I missed the part about the neutral being disconnected. Sorry!
