== Trivia == | |||
[[User:overflo|I]] started Blinkenpoi ~10 years ago and respawned that project 6 Weeks before CCCamp19 with a new Microcontroller, a Webinterface and modern Ledstrips. | |||
The Webinterface has some cool features like "Local scan" to find other Blinkenpois automatically when they are connected to the same hotspot / mobile access point. | |||
You can synchronize the playback on multiple devices, you can create, upload, download and share Animations directly in the Webinterface. | |||
The Blinkenpoi opens its own Accesspoint for wireless setup and features: | |||
* Local storage of wlan credentials | |||
* Auto connect once configured | |||
* Reset of configuration | |||
* Verbose Debug Interface over usb->serial | |||
* 3Mb storage for custom animations | |||
* Firmware written in C++ (Arduino Framework) | |||
* 100% Open Source Public Domain / Do whatever you want | |||
== Usage == | |||
Whenever you turn on a Blinkenpoi, the first led will shine in bright pink. | |||
You have 2 seconds to press the button and override network setup while the led is pink. | |||
If you override the setup the first available animation is loaded. | |||
You can cycle trough all available animations with the button till the Blinkenpoi turns dark again. | |||
If you press the button again the first animation is loaded again. | |||
If you press the button for 2 seconds or longer the first led will flash red 3 times and the local config is erased. | |||
All credentials and configurations are purged and it will open an Accesspoint on reboot for configuration. | |||
When you turn on the Blinkenpoi for the first time, it opens an Accesspoint called "Blinkenpoi". | |||
Once connected to it, you will be greeted by a captive portal / WLAN setup screen where you enter the credentials of the WLAN your Blinkenpoi should connect to and a name for the Blinkenpoi. | |||
The led will turn from yellow to green and then dark if the Blinkenpoi connected successfully. | |||
The Blinkenpoi is now connected and can be reached at [http://blinkenpoi.local http://blinkenpoi.local] from a machine connected to the same network. | |||
There is a webinterface for configuration, network scanning, animation playback and animation creation available directly on the Blinkenpoi. | |||
== Assembly Instructions == | |||

Video: [https://youtu.be/9AM9bLseyD4 Blinkenpoi assembly] | |||
== Animation format== | |||
The Animations are saved on the Blinkenpoi in a raw format. | |||
Each Pixel has 3 Bytes for RGB, There are 50 Pixels, but only 25 on each Side. | |||
We save 25*3 Bytes / Column and simply read the bytes back from the file and set the RGB values from that data. | |||
No headers. no metadata, but super fast. | |||
When we reach the end of the file we just set the filedescriptor to seek(0) and start over. | |||
== User contributed Usage guid == | |||
pink: colour after starting the poi - press button now to ovverride the network setup - longpress leads to NETWORK RESET and 3x red blinking | |||
white: connecting with previously configured network | |||
green: connected with configured network | |||
yellow: Open Access Point on Blinkenpoi for setup | |||
Reset Wifi-Setup: | |||
After starting, when LED is pink, press and hold the reset-button. Then the LED should flash red three times. | |||
Connect Poi to your Wifi: | |||
Connect the Poi via USB to your Computer. | |||
Search for Blinkenpoi in the accessable networks. | |||
Connect to it. | |||
A captive portal is opened (browser popup). | |||
If it does not open automatically open a browser and go to [http://192.168.4.1] | |||
Choose Wifi-Setup in the menu and choose your wifi (for example the Hotspot of your Smartphone), enter the password and click "Save". | |||
The poi should turn from yellow to green after a couple of seconds and turn dark on successful pairing to the hotspot. | |||
Now, when you start the poi, the LED first flashes pink, then white and finally green and turns off again. | |||
In your Wifi-Device/Smartphone open the Browser and enter blinkenpoi.local. | |||
If your device does not support MDMS - which is the case for android - you have to enter the IP-Adress of your Poi. | |||
If you don't know its IP address you can use nmap, look on the router or attach a usb cable and take a look on the terminal provided by the blinkenpoi. | |||
for example '''screen /dev/tty.usbserial0 115200''' | |||
or you could connect another computer that can resolve nDNS to your hostpot and open http://blinkenpoi.local in the browser | |||
