Title: Unicorn's Arduino Explorations
Post by: Unicorn on February 21, 2016, 10:46:55 pm
Hey! So I just recently got myself an arduino mega, an ethernet shield, and a 2.8" LCD TFT Capacitive touch breakout board from adafruit. This is were I'll be posting about my adventures and questions with and about these items.

I also want to know, are there any good, simple calc modding things that I could do with an arduino? I do have the 83+ SE for its spacious case.

So the first thing I did:
I created CircleIt (https://www.cemetech.net/programs/index.php?mode=file&path=/84pce/asm/games/CircleIT.zip) on the Arduino using my Adafruit LCD.

#include <Adafruit_FT6206.h>
// The FT6206 uses hardware I2C (SCL/SDA)
Adafruit_FT6206 ctp = Adafruit_FT6206();
// The display also uses hardware SPI, plus #9 & #10

Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);

Its great fun, and I'm thinking about what to do next with these things. :)


Oh yeah, I got a hc-05 Bluetooth module from my robotics teacher and got that working with an arduino using the arduino IDE's built in serial port.
I decided to make it a little more fancy and create a ruby program to interface with it. But, I got a permissions error of some sort when trying to interface with the Bluetooth. But, when trying to interface with an arduino everything worked fine. I asked about it here: http://stackoverflow.com/questions/35190016/bluetooth-serial-port-permission-error-errnoeacces-ruby-serialport-gem

Wow, how did I miss this? THis looks pretty cool @Unicorn  and I kinda feel bad for noticing this two months after it came out. Is that a port of CircleIt? Because it definitively looks cool. :)

Haha, thanks! Yeah, it is a port of CircleIt, something I just wanted to attempt to learn that graphic library with something.

Ok thanks for the info :). I wonder if you could port FloodIt if you succeed in making this game for the CE? :P

I haven't posted here for a while...

Anyways, I recently got a lattepanda (http://www.lattepanda.com/), which is essentially a 1.8 GHz computer with 4 gb of ram, with an arduino processor built in. Its a really nice little device, but it tends to overheat. To counter this problem I took a heat sink off of an old dell computer I had, and also took the fan. I hooked the fan's Power and Ground wires up to the arduino's 5v and GND, and voila! Whenever the panda gets power, the fan starts up. The heat sink sits on top of the box around the processor.

The thing is though, the panda may not be on, but the fan will be running. To only make it so that the fan runs when the panda is on, I'm going to write a program using their sample code (http://www.lattepanda.com/docs/#Inputs_and_Outputs) and make the program run when the computer starts up.

Interesting, I wonder if it could be used as someone's main computer if he isn't gaming a lot?
Title: Re: Unicorn's Arduino Explorations
Post by: Unicorn on July 25, 2016, 07:22:19 pm
Probably! The Enhanced version (4gb ram, 64 gb emmc) can run minecraft with optifine at low graphics, 2-6 render distance.  But if the board is overheating, it can barely load the game. So you would want a good cooling system to use it as a main pc. You would have to install more storage space with an external drive, but I guess that isn't that had to do. Also they coulnd't be doing more than surfiing the web, managing files, no hardcore programs running.

Since Claw will be made to run on the Mega too, I could port your game XD

Maybe!

So I have a question: Do you think I should put the board on top of the heat sink with the fan behind it like this:
http://imgur.com/4o4xpK3

Or with the heat sink on top with the panda held up by supports, like this: (the supports will be screws or something on each corner)

http://imgur.com/cH5vtYN

What would be the best design for keeping the temp down?

Post by: DJ Omnimaga on July 26, 2016, 07:57:14 am
I am not tech-savy so I can't really help you on that, but I think this fan might need a bit of cleanup :P
Title: Re: Unicorn's Arduino Explorations
Post by: Unicorn on August 01, 2016, 12:25:27 am
Yeah, it does, but I may never get around to that. :p


But anyways, I made a thing!

I re-hooked up the fan to the green airflow conductor, and wedged a piece of wood with the lattepanda screwed onto it between the edges.

Here you can see it in the "case"
(https://codewalr.us/proxy.php?request=http%3A%2F%2Fi.imgur.com%2F3CFDuI2m.jpg&hash=0b1cdbc7df5a63822b14c64a8272f941)

As you can see, there is a small block of wood resting on the hood, as well as a cutout along the side. These two things exist to let the Display connect and have a mount. You can also see the Coasters in this image, making sure that it does not tip over. I have since put some nails halfway into the fan that support it now.

(https://codewalr.us/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FbVSa2oum.jpg&hash=eb3ca3e8568d2bfbdf86d11cf5b04508)

From this view you can see the fan and the lattepanda itself inside:
(https://codewalr.us/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FfQlXqoJm.jpg&hash=59779154eab0e2eb8310a7d3818e4b70)

Now, I haven't mentioned the heat sink, but it is in there, just resting on top of the CPU. I have ordered some thermal paste to make it more permanent. You can also see the fan's wires, which go to 5v and GND pins.

(https://codewalr.us/proxy.php?request=http%3A%2F%2Fi.imgur.com%2F851bq71m.jpg&hash=6d3feab90af0512fbc9ce0244ab33a77)

And here is a picture  of what it will look like most of the time:

(https://codewalr.us/proxy.php?request=http%3A%2F%2Fi.imgur.com%2FK9jCkJpm.jpg&hash=64059f604f78e2947bf631d653c490ef)

This seems to be pretty successful cooling, it is averaging 50-45 degrees Celsius while writing this post, while it used to average 75-80.


EDIT: I also have another  question, this time about ArTIcl. I followed along with geekboy's how-to video, but I am wondering if there is  a way to get what key is being pressed on the calc. For example, if I press [Enter] on the homescreen, It sends some sort of data to the Arduino that I can read over serial.

yup, I've posted about it on cemetech, so i should get help soon. For now im gonna see what i can do using the examples.

Also @Juju did some Arduino stuff in the past so perhaps for non-Calcnet stuff he could help you or give you ideas (or if he has unfinished Arduino projects maybe he has the source somewhere?)

My experience with CALCnet is limited to direct assembly. I don't use libraries. Is this an Axe project, or an asm one?

I'm actually attempting to use the TI Keyboard as a Computer Keyboard. I just need a way to receive data from the 2.5 mm cord.

Its not a calcnet project. ;)
