Errata corrige in the third line:
"I noticed that sometimes it freezes and doesn't boot properly, while the red led (that states it's ON) remained off"

Oh yeah, they can be random.
If you haven't, add some caps as close to the power pins as you can. It's very jumpy with the power and some filter caps solve most of the instability issues.

Also, look up some range tests on youtube for it. It's a bit scary.

>>989956
wouldnt it burn before doing any sort of damage to you? i mean, if it was really doing that 3.3w transmit with no heatsink it would most likely burn pretty fast, right? (isnt that chip power rating about 100ma or so?)

>transmit data is like ac @ 2.4ghz
>low voltage ac tingles
can this be your explanation op, i mean the antena is bare copper

Yeah it's alright

No it's awful

>>989947

The clip looks like this. The impellers are sliding out and getting jammed without the clips there

Looks almost like a window handle clip, though for your purpose you should be able to use something like a snapring in its place.

looks like of of those springy hose clamps that go on without tools.

Read lots of other patents of similar products.

Get a slippery as fuck lawyer.

Have lots of money.

Pray that another patent doesn't get approved during the 2+ years time it takes for yours to go through.

If you're a university student, there is guaranteed to be a professor or other faculty member somewhere experienced in the patent process.
Just ask anyone that looks like they've been around for a while and they should be able to point you to someone that can help you.

Also it doesn't need to be in the same college.
Go look in the college of engineering, business, etc.

Can I run a 12v 500w amp from an of the shelf wall wart?

>>989601
Sure.

If you can find a 42 amp wall wart.

Unless you have a pretty beefy computer power supply lying around your best option to power that sub is probably just buying a home audio amp or receiver. You could just run the car amp off a 12v battery inside but that would be the niggest of rigs and you'd have to charge the battery and shit.

"dremel glass tip"

The sad truth is your not capable of much, if you are here asking stupid questions that you could of just googled.

>>989548
I'm taking out of my ass, but can you laser-engrave glass? You could go to a makerspace or uni or friend with a laser cutter

I really love the old world style of printing and book making. Classy as fuck.

There are a few good videos about it on youtube.

I used to make them by getting the block of paper set up between two thin bits of wood, then clamping them down firmly- mark out the holes about 5mm-1/4" from the edge and then drill holes along the length with a small (generally 2mm) bit about every 1cm or so. Then take the boards off, get waxed cotton and bind the core of the pages together with a ringbolt hitch down the length.
Nice thing about the ringbolt is that its got a bit of room so you can either sew the spine to it or it'll have enough 'meat' so to speak to have glue to grip to it.

Perfect binding with a binder clip and some pvc glue. Easy but very useful if you have loose papers you want to bind for any reason.

Dude, just buy new shoes.

>>988799
I'm not going to buy something new of anything if I can fix what I've already got.
If this doesn't work, then I'll buy new shoes.

Dremil with a little cutting disk.

Cut/grind a slot in them and apply a large slotted screwdriver with a big bar on it.

Hack saw with the blade on the 45 degree angle.

Have you got a schematic of that part of the circuit? If its simply a crowbar diode you should be able to use something else.

How did you blow it up?

I'm guessing it was a bad charger, I'm going to throw out all my cheap chargers soon and only use the reliable ones.

I just woke up one day and the battery was draining super fast (flat in 12 hours standby) and the phone was warmer than usual. Opened the back out of curiosity and saw the burnt ic. Not sure if it's clear in the image though.

And I think so, I'll check the service manual.

You should be able to just replace the whole USB board for a few bucks.

Shove it up your nephew's rectum, switch it on, then go buy a new one.

use one hand to bend it back, another hand up your ass

More wrist action, you know, like a spoon. It'll take seven second longer to stir your coffee, but you'll be able to brag about "roughing it."

i did it in my parents bathroom as a teen with india ink and a sewing needle
it was 100% not safe but i didn't have any infections. however, it faded like mad so if you get it on the finger like in the op pic you're better off drawing it with a sharpie. I put my needles in boiling water for an hour and basically soaked them in rubbing alcohol to cool them down. I used piercing antiseptic for the aftercare.

Yep I've got one it's of a crab/spider.

No way in hell you're going to get the 5Ghz band to travel 300 feet.

Even with a parabolic antenna or directional antenna?

How many walls will the signal have to go through?
