Now I am requiring more speed for hopefully the same coding, and I am thinking in the Arduino Due (84 MHz Clock) which is enough faster than the Arduino Mega (16MHz Clock) but imposes working with 3.3V, hence using some 3.3V 5V level conversion for every input and output.

Others, like the ADS1241, have "split power" where you can have different logic voltage (DVDD) and analog voltage (AVDD), so you just run the logic at 3.3V and the analog at 5V so you don't need a logic level translator.

I think we all know that the uC on the Mega 2560 is very crappy uC for today's standards.
I am looking for a better and faster uC board much like the Arduino Mega 2560 that can be programmed with the Arduino IDE, and has the same voltage levels (5V operating voltage, and 12V input)

For what I need imagine this:
I have close to 10 sensors, of which 8 are analogs. The "board" should be able to read all of these sensors, do some calculation, and send the calculated values of these sensors to computer using very fast serial communication. The "board" should be able to do these tasks every ms or less... This is the kind of processing I am doing.
I have tested this kind of thing with Arduino, and it crashes all the time. Simply put, Arduino does not come close to the processing power I need.

eg. The thing I'm building right now uses an Arduino Pro Mini for main CPU (Mega328) and a Tiny85 chip to control a WS2811 LED strip. I added the Tiny85 because the Mega328 needs to have interrupts enabled and a long WS2811 LED strip prevents this.

Arduino has the processing power needed, just maybe not the speed you need due to the calculations you are doing.
If you replace the Analog read with an external SPI interfaced ADC, you can get a lot of time back.

A 3-byte SPI transfer is needed to command a conversion and read the result. Which takes 3-4uS? x 8 = 40-50uS.
So now you have most of 1000uS available for other stuff.

Hi all, could anyone tell me if it is possible to increase the processing speed of my Arduino Mega? If yes, can anyone tell me how and by how much? I want it to run fast and reliably. I'm thinking about doing it for fun. Thanks.

The ATmega2560 on the Mega is only rated to run at a maximum speed of 16 MHz, which is what it's already at. While it's possible to overclock, operating outside the limits specified in the datasheet could result in unstable operation and thus would not meet your requirement of reliability.

If you finally do find a need for more speed then of course you can accomplish this by switching to a more modern microcontroller. The Arduino Due has the Mega form factor but with a much faster processor. Other popular options are the SAMD boards such as the Zero, Teensy, ESP8266, ESP32, STM32.

Once you do that, you need to change the baud rate used to upload the code. If you don't get this right then you can't upload any new code. There's only one clock on an Arduino so unlike overclocking the core of a PC, any small change will change everything.

The Due is already running at 84 MHz. Of course clock speed is not going to be an absolute indicator of processing speed when you change architectures but certainly it's going to be faster than a Mega. It looks like it should be possible to increase the clock speed of the Due but you'd need to do some research on that (probably starting with the datasheet). I have no experience with Due.

I know that overclocking of the Uno/ATmega328P beyond the rated 20 MHz has been done, more just for fun than for practical reasons. You can find some YouTube videos and other documentation of this where people are using various techniques for cooling the microcontroller at unreasonably high speeds.

I just installed and tested mega-cmd, the official command-line tool from MEGA. With the mega-get command i get around 20MB/s which is awsome! Does anybody know how complicated is it to integrate this into rclone?

Problem solved: after installing mega-cmd i started a webdav server with the "mega-webdav"-command. Now it was possible to create a new remote with type "webdav" (according to the description of @asdffdsa).
This new remote was mounted to a local folder with the rclone mount command. Now the down- und upload speed is around 20 MB/s
Thanks to @asdffdsa !!!

Mega Speedup is an Enhancement that can be used to speed up the Mega Evolution of a Mega Evolving Pokmon. More specifically, they decrease the number of icons required for certain Pokmon to Mega Evolve, allowing the Mega Gauge to fill up faster. Each Mega Evolving Pokmon can use a certain number of Mega Speedups, and each one will decrease their number of icons needed by one. Mega Speedups can be obtained from various events, notably Competitive Stages in which one must rank among the highest few thousand.

Mega Speedup was first introduced on the May 26, 2015 update of the 3DS game (v1.2 onwards), and was available from the start on Mobile. With the introduction of the Enhancements mechanic on 3DS v1.3 and Mobile v1.6, the Mega Speedup was reclassified as such.

There isn't really one counter to Mega Gengar. Due to Shadow Tag, you can't switch freely, and lets face it, you'll most likely lose one or two Pokemon at least to Mega-Ggengar before you can take it out. There are a few ideas, but all of them involve some amount of luck/ timing.

Scarf Chandelure will outspeed Mega-Gengar for sure, even with Modest nature, but cannot switch in to it safely, so it has to Revenge kill. Infiltrator will by pass Substitute and OHKO Gengar with Shadow Ball. Chandelure is more viable over wifi, as it's not Uber tier material on Showdown.

While Bisharp doesn't outspeed Mega-Gengar, it's resistant and immune to Gengar's two STABs respectively. Mega-Gengar usually carries Substitute, and more often than not either Disable or Perish Song, meaning it frequently forfeits Focus Blast coverage. Bisharp still can't tank any special hits, but at least it's resistant to Shadow Ball and can break the Substitute.

Mega-Mewtwo Y can't switch in safely to Gengar or break its Substitute without fainting, but it can OHKO Gengar with Psychic if it's not behind a Substitute and deal it with it that way. Problem is that Mewtwo can't be bred, so you have to get lucky and get a perfect speed IV (though all legendaries in X&Y have 3 perfect random IVs when caught).

So the problem with Mega-Gengar is that it packs Disbale. However, it loses Levitate meaning T-Tar can use Earthquake or Crunch to OHKO it. Sand Stream also gives some nice residual damage to Gengar, in addition to allowing T-Tar to take a Dazzling Gleam before dealing out damage.

Seriously? Diggersby? It's not as stupid as you think. But - this will only work if you face a stalling Gengar that only has Shadow Ball. Disable could really mess you up if Diggersby is choiced and Gengar is behind a substitute, so you could run an Agility Life Orb set instead.

One unboosted Bullet Bunch will manage to cut Gengar's Health in half, and Mega-Gengar has no reliable method of recovery except Rest. If Disable gets you, Pursuit is the other move you can use on Gengar. Scizor can't break Substitute, but it can Pursuit trap Gengar should your opponent choose to switch out.

So as you can see there isn't one answer to Mega-Gengar. It's got high speed and advantageous typing, meaning its immune to most priority moves. There are pretty much no safe switch ins to Mega-Gengar.

If you really want a hard-counter to Mega Gengar, go with Tyranitar. It pretty much traps Mega Gengar in with Pursuit and Focus blast fails to kill it if Tyranitar has an Assault Vest. Be sure to keep your Tyranitar healthy though, and only bring it in for a revenge kill.
Other than that any strong Pursuit user would easily eliminate Mega Gengar.

Ghost types can easily come in and out on Gengar now, and strong priority Shadow Sneaks can wipe it out. The best user might be Aegislash in OU and Giratina-O in Ubers. Sableye can unleash it's Prankster Thunder Wave and cripple Gengar for the entire match.

OK, I'm imagining that this is not a stally Mega-Gengar, otherwise you could just use your Bisharp. If it's an staller though, I've found quite an unorthodox and uncanny slap-in-the-face answer, which is:

Alakazam is faster than Gengar when they are both in normal form, and in Mega form, so there is no way he is out speeding you. Gengar do not tend to carry Sucker Punch, especially Mega one, because they generally out speed everything anyway, and because Mega Gengar is a special attacker and Sucker Punch is physical. Believe it or not, due to Gengar's Ghost / Poison typing, it's actually weak to psychic attacks, so a STAB psychic should finish it off in one hit.

I am really getting the new bike jones out here, probably since we are getting nailed with snow and riding won't be happening for at least 6 weeks now ugh. I am looking at getting a Nukeproof mega carbon frameset and I see that they have a bunch of different coil options to choose from and I have always wanted to be able to ride a coil shock (and not have a 38 pound bike to lug around on the trails).

I have heard that the EXT Storia is an amazing coil shock but I also saw this Fast Suspension Fenix EVO shock available for the same price as the EXT shock frame. Has anyone had any experience on either that they could share? I'd really appreciate some input!

I Have never ridden a FAST coil but i Have just built up my Giga with the EXT - i am running a 25lb higher spring than recommended for a little less sag (around 27.5% instead of 30), I have followed their shock setup guide exactly.. and the bike is the best thing i have ever ridden.
