Well in that case probably most things, mostly its going to come down to IO and other features you want to have.
ESP32 is fairly solid, there are some good STM32 chips out there as well for a more barebones setup. I would say stick to 32bit MCUs if a small increase in cost and slightly higher potential power draw is not a concern as it gives you more flexibility for new and current features. Though from the description you gave (might not be the whole picture and don't know the design specs you are work with) you might be able to get away with an 8bit micro like the AVR or PIC family but you might end up scratching your head a bit more when coding up the firmware.
Good luck with the design 🙂 

2 ms should be fine for most Micro's
personally I would go for something like the AVR 328p, esp32 or the Due to get the required speed without having to deal with the complexer cpu of the Raspberry's and the boards limitations for use as a Real time mcu

Raspberry Pico might be an option as well or and ESP32 chip with FreeRTOS
 

New student flats in Middelburg, the Netherlands.
They are designed in such a way that they seem to spell "LUL". 
Which is dick, in Dutch.

 

Ordered some Hardware last week from ebay and Aliexpress. 
Xeon e5 2560 v3 64gb of ecc ram and a Chinese designed "x99" mainboard, like a nice stuff for a workstation that is not meant for games, but it hasn't shipped yet.


i hate waiting 😕


 
Hy !

Intels afraid because the macs are good.
Like really good.
And 10% of poeple who had macs with intel are people who apple is trying to get to upgrade to apple silicon.
 

I think the 65W mode on the OnePlus charger is a proprietary charging mode, so the charger may only provide 45W to the laptop because that's the maximum it can do in PD mode.

Blackberry Keyone, did I need to buy an outdated android phone from 2017, no of course not. But am I gonna buy an outdated android phone thats brand new in box for $20 from work when offered? Every time. 

Such sad news. I can't even imagine what the team is going through. I hope all that read this go hug your kids wife and make sure you at least call your parents often. We all take for granted the life we live. I was 30 when my heart stopped one day I was healthy and fit but happened to have a heart condition I didn't know I had. I'm here now but I know how important it is to always tell how much you care for them. Sending my heart to the whole team because I know how much the lose of person can hurt. 
 

I don't recommend using a 1b for an octoprint server. Gcode interp. and webstreaming is harder then you would think and the 3b is the recommended minimum atm. 

1 (1b) Running Pihole (this one broke D:)
1 (1b) Running Logitech Media server for squeezebox
1 (pi Zero) connects to my powermeter to see current power and gas usage
1 (3b)  Running homebridge and custom home automation software
1 (1b ?) is gonna be a an Octo print server

i own 3 1B originals. Bought one when they came out, as so did my brother, he stopped using his so i got it. and around the same time i got one from my internship
the Zero i bought as an impulse buy, the 3b was bought to play around with for the custom software

Thinking of buying a 4b (4gb) to replace what the 3b does, and run pihole on the 3b
Or run pihole on a VM on my nas ?

The problem with 3rd party cheap chargers are bad terrible power supply's that can destroy the phone.

iOS has software level protection for the Lightning connector. (if you connect it to a computer is asked, do you trust this device). that only shows up when the device is unlocked. if the device is unlocked. the port goes in to charging only mode
 

I think I got everything... if you have any questions, ask below

The first step is to decide what you want your setup to be, as you'll need to know how many parts to order. There is a few different options, and once you've chosen, click on the parts list for your respective setup.
 
1. Single Camera w/o hub server
Parts list: Pros Least expensive setup Cons Lower attainable FPS/res 2. Single Camera w/ hub server - *RECOMMENDED*
Parts list: Pros allows for future expandability higher attainable FPS/res more reliable vs. no hub Cons costs more (you have to buy a second Raspi) 3. Multiple Cameras w/ hub server - *RECOMMENDED*
Parts list: Pros higher attainable FPS/res more reliable vs. no hub Cons cost (lol, 2 cameras + hub is still cheaper than a Nest cam) 4. Multiple cameras w/ a desktop computer as a hub
This is a setup that you can build, but I haven't investigated it yet, so stay tuned on this.  
My recommendation is to have a hub server regardless of the number of cameras to ensure the best possible image quality, but if your budget doesn't permit, a single camera w/o a hub server can still work decently.

I own a HP Microserver Gen 8 (G1610t) and it's a pretty good nas. got it for 220 Euro's
 
did update it to a i3 2220 and 16gb of ram

hmmmm... This is actually a very complicated question and there is no one word answer. Sorry @JDE

It depends. There are generally 3 types of "programs":
Sequential Parallel Parallel/Sequential (and inversely, Sequential/Parallel) A sequential task is just that: A task that can only be completed by completing the steps in order. In other words if I want to, say, generate a Fibonacci sequence:
def fibonacci(n): a = 0 b = 1 for i in range(0, n): temp = a a = b b = temp + b return a It is easy to see that this task can only be accomplished in order. There is no way to do multiple steps at one time.

A parallel task, however, is one where the steps can all be done at the same time. You will not see a coded example (due to the complexity of such programming). Common parallelized algorithms are sorting algorithms.

Finally, we arrive at parallel sequential tasks. These are tasks which fit into one of two categories: Either there is some work done in parallel, the results of which are sent to a final step, or there is some initial steps, the result of which is sent to various threads to be worked on in parallel. Here is a simple example in no specific language:
 
# add 5 to a, add 6 to b, add a and b thread_one(n): return 5 + n thread_two(n): return 6 + n a = 2 b = 3 c = parallel_magic(thread_one(a)) + parallel_magic(thread_two(b)) This isn't quite how things work, but you can see how we can work on thread_one and thread_two at the same time, but we cannot arrive at the final result without the results of both thread_one and thread_two.

But what does this mean for your question?

It's simple: Sequential problems prefer a higher clock rate, parallel problems can benefit from more cores.

Disclaimer:: This explanation contains gross oversimplifications.

A combination of voltage AND current kills you.
 
That 400kV is very low current, and the current is so low enough that is unlikely to hurt you because the human skin is usually dry and has high resistance. If you were to break the skin and insert the wires in your blood or something like that, you could kill yourself.
 

Don't now if palm scanners are a real thing to be ownest 
 
but there are some cheap arduino compatible finger print scanners on AliExpress

for 2 , yes you could with the use of correct electronics (a transistor and some resistors) connect the pc powerpins
and for 3. you could make the arduibo emulate a keyboard and let it type your password

Also worth noting that almost all XYZ printers are DRM cartridge locked like ink jet printers... pretty much the only manufacturer to do it.

i rather have a hub (or acces point) dedicated to the bulbs. but more to make it easier to controll them. a wifi radio can have 127 devices connected to it. so your not gonna run in to a lot of problems there.  for data my longest running Xiaomi Yeelight has used arround 100MB in a year.
 
and offcourse keep them in a different network. i have my iot devices in a different Vlan, that is closed down with my Home automation server on the main Vlan and the iot Vlan

To add to this the TP-Link does seem to have an API

An iPhone.

Windows and Mac Os both accept SMB pretty easy, so freenas or just plane windows is great
 
With freenas you could make a Time Machine Share so that the mac's can backup to it

Mate what are you talking about?
