TiLDA MK3/NeoPixel

2016-08-24T19:32:24Z

JasperWallace: add some urls to examples.

One feature of the Mk3 is a single NeoPixel multi-colour LED adjacent to the red power/charge LED.

==Faulty manufacture==
Unfortunately, during the original manufacture of the badges the NeoPixel was mounted 180 degrees out of orientation. As originally delivered it will not function, being mounted with the triangular notch facing the outer part of the badge and the chip part of the LED (the brown spot under the transparent plastic) facing the charge LED. The correct position is with the triangular notch facing inward and the chip part facing the "D1" label of the silkscreen.

===Correcting the faulty mount===
The best solution should be to use soldering tweezers take the LED off, clean the pads, turn it, and put it on but this is a delicate operation that will probably destroy the LED. The trick is to be quick, to use a fairly high temperature (350-370 degrees) and add some new solder to the pads to increase the heat transfer.

You can possibly use two soldering irons at the same time, one on each side of the LED.

Avoid hot air at all costs, the badge is packed and you don't really want to risk blowing the charging LED away or even worse, damaging the LCD.

==Programming the LED==

TiLDA MK3/Run Code

JasperWallace: /* Option 1: REPL */

This video is meant for the micropython board, but most of it works similar on the TiLDA: https://micropython.org/

= Option 1: REPL =
REPL stands for "[https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop Read–eval–print loop]" and allows you to run python code, line by line. This is a great way to see effects of certain hardware commands instantly and to test basic python features.

This allows you to run code, line by line, on the badge and to see the effects instantly. Follow https://micropython.org/doc/tut-repl or follow step 1-4 on the [[TiLDA_MK3/Get_Started|Get Started]] guide.

<strong>Note:</strong> This will only work if you have an empty <code>main.py</code> on your badge to stop the home screen from taking over instantly. If an app or script is already running you will not get a REPL that you can use to program, but simple debug output instead. Remember to remove it afterwards if you want to use the home screen again.

You can also press Ctrl-C to stop the currently running app and get to the python prompt.

= Option 2: Copying files =
You can also copy your code to <code>main.py</code> on your badge, safely eject and then reset the badge via the button. To debug it you can use the serial console (see option 1) which will show you all text printed via <code>print()</code> and errors.

<strong>Note:</strong> It's very important to always correctly "eject" the usb storage before pressing the reset button, otherwise your filesystem is going to corrupt and you might have to [[TiLDA_MK3/reset|factory reset]] your badge

Remember to remove your main.py afterwards if you want to use the home screen again.

= Option 3: pyboard.py =
You can also use micropythons's <code>pyboard.py</code> script to automatically run a full local file of code without having to worry about copying it line-by-line or ejecting your device.

You can find a quick introduction on how to set it up [https://badge.emfcamp.org/wiki/TiLDA_MK3/Get_Started#5._Run_a_whole_file_of_code here].

This option is very useful as a build script with your editor, it allows you to quickly test whether your app is working.

<strong>Note:</strong> While this option works even if you run the home screen, it works slightly better if you have an empty <code>main.py</code> on your badge.

=== Sublime Text 2 build script ===
OSX:
<pre>
{
"shell_cmd": "/path/to/your/pyboard.py --device /dev/tty.usbmodem* $file"
}
</pre>

JasperWallace: add new blog link

The aim of the EMF badge is to give people interesting hardware they've probably not experimented with before while being simple enough that anyone can play with it.

==EMF2014 - TiLDA MKe==
[[File:Tumblr_inline_n9znh3W5tC1rpuop0.jpg|right|thumb|Front]]

The [[TiLDA MKe|TiLDA MKe project]] is code named "ElectroMagnetic Boogaloo"

The MKe is an entirely new design, based on the Arduino Due. It brings an LCD display, Accelerometer and Gyro, along with a long-range wireless transceiver. The original specification was to give people live schedule updates and camp notifications, but the hardware was capable of much more.

Please Note: There are a couple of minor hardware and some firmware issues with the MKe that might be effecting your badge. If you've let the magic smoke out of your charge controller or have tried to re-flash and ended up with nothing but a couple of dimly glowing lights then DO NOT DESPAIR -It's recoverable and fixes, documentation and lots of firmware are still being produced :)

[[SiNE|SiNE: Investigating the Neighbourhood of EMW]]

Each attendee of Electromagnetic Wave received a SiNE badge, allowing them to take part in a treasure hunt based around the boat. By solving the clues, attendees were directed to an object or location either on or near the Stubnitz. The clue letter was also the first letter of the answer - large matching letters fitted with IR code transmitters were stored at each location. Holding your badge in front of the letter lit the corresponding light on a badge, allowing the user to collect them all!
