Best hex nuts according to redditors

I thought now would be an appropriate time to share my first RPi project. Here are some links to more niche parts I used:

Raphnet Adapter

Standoffs

Disconnectable cables (for easier cable management, not necessary)

I used this kit of M3 standoffs for one of my projects. I chose that kit only because I needed some super-low-profile 2.5mm ones in order to tuck a Pi Zero behind a display which was mounted atop the 15mm ones. It only comes with 10 of each size, however, but if you don't mind mixing things up and having the Pis at different heights off the board, that will get you what you need.

Otherwise any M3 standoffs should do the job. I used nylon standoffs just to avoid shorting anything, but I'm not sure that was even necessary. Brass standoffs would probably work too.

EDIT: Pic for reference

This is the drone that I have built:

Been slowly building my first quad over the past month or so. Just when I have time. I bought a cheap carbon fiber kit off amazon. I will list everything I have bought so far.

Fly Sky FS-i6 Transmitter https://www.amazon.com/gp/product/B00VE3PZ3Y/ref=oh_aui_detailpage_o04_s01?ie=UTF8&psc=1

Fly Sky FSia6b RX (need this to run PPM instead of PWM): https://www.amazon.com/gp/product/B00VE3Q3XU/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1

LHI quad Kit with ESC's, Motors and Flight Controller: https://www.amazon.com/gp/product/B010FMGUS8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1

Now the above kit comes with a CC3D flight controller, after some research, I decided that I would use a Naze32 rev6 board instead. I purchased that from Hobby king, I will list all hobbyking purchases after amazon.

These are all the hobby king stuff that I bought:

Besides a lipo charger, the above will get you flying! Below is everything needed for the FPV aspect! I used to run RC cars so luckily I had a lipo charger from those days

Now this is prolly the most basic, beginners fpv setup that you can buy... Its perfect for learning and crashing lol. I have about 3 flights with mine so far, about 4 batteries. Buy props lol, lots of props. Already had to change 1 arm too.

5/16-18 all thread into that, nut flat washer plywood flat washer locknut nut in that order, and Robert is your mother's brother.

I would probably do eight, three on the top, three on the bottom, then one in the middle on the sides. Might go up to 3/8", this is just the first search results of the appropriate kind of parts I was looking for. If you're fancy, you can even get wing nuts for the outside nut to allow it to be hand openable.

Bite the bullet and just use these. So damn simple and no-nonsense.

Pre-G12/H55: my 1080 SC2 8GB was 73 @ load, 33 @ idle.
Post: I've yet to see it breach 53 @ load, lowest idle is 22.
Exactly what I needed for my Phanteks P400S.

I re-used the backplate by keeping the screws in-place and snagging 20 (a few extras just in case) 5/32" 1-72 hex nuts and 1-72 washers - both from Lowe's for $2-3 combined.

"The ESCs do not have a BEC, you will need to supply 5v power to your flight controller with a UBEC or stepdown voltage regulator" -Hobbymaterc

You will need to get your own BEC.

https://www.amazon.com/Naze32-Flight-Controller-Distribution-Multicopter/dp/B00UFK8VJ2/ref=sr_1_2?ie=UTF8&qid=1479613994&sr=8-2&keywords=PDB+5v+12v+arris This is the one that I use, and I can say it works phenomenally (the 5v regulator is inside a power distribution board). Plus the PDB will help clean up your wires.

The cool thing about this PDB, is that it was made to be the same size as your CC3D, so if you get something like this: https://www.amazon.com/dp/B014K8MXO8?psc=1 , then you can mount them on top of eachother like this: https://oscarliang.com/ctt/uploads/2015/04/zmr250-PDB-Installed-and-Naze32-FC.jpg , making the build a whole lot cleaner.


You need to hook your 12v battery directly to the positive and negative pads of the Arris PDB, and then use the 5v regulator portion (always check with a multimeter that it IS outputting 5v before plugging in) and then plug that into your FC. Plug your FC into the FS-R6B receiver and it will light up.

To use the receiver while on your software (I'm assuming openpilot), you will need your FC hooked up into the PC AND powered via the 5v regulator.


Important side note: The FS-T6 has a safety feature that when it loses telemtry, the FS-R6B receiver turns off and therefore turns the craft off. This means that when you turn the receiver on, and your transmitter is not on, it will not light up, rather it will blink red the moment you plug it in, and then turn off. Simply turn on your transmitter, and then you'll see a solid red LED, given that your transmitter is already binded with the receiver.

I believe they're 2.5M, I bought this one or something similar.
