Next in LoL Shield history: a sort of “growth simulation”:
- Place a particle (say: light a LED) at a random place on the shield.
- start a new particle at (0, 0).
- move this particle randomly; north, south, east or west.
- if the particle hits a placed one, fix it at its last free place.
- repeat from 2. until (0, 0) is occupied.
- then blink the result, clear the screen and start at 1.
If the movement crosses a border then move to the other side. Mathematically spoken: we are on a torus.
First a short video
For a long time I’m addicted to blinking LEDs, so it was only natural to buy a LoL Shield by Jimmie P. Rogers. I ordered it at Watterott and – as usual – they delivered very quickly. With trembling hands I unpacked the parts – and decided to wait until tremor disappeared. After reading some descriptions of the assembly and watching this recommendable video from Super Awesome Sylvia. I started to solder the 126 LEDs; a good exercise.
This is a new version of the evil spider. I’ve replaced the LED in the head with two smaller LEDs in the eyes. This way the brightening is easier to see.
Some close-up photos are at the end of this post – if you fear spiders, scroll slowly down to the image with breadboard 😉
(BTW: at 00:10 you can see Daniel)
The source code is rather simple:
Finally my birthday present arrived: the Cube4, a 4x4x4 RGB LED cube by freetronics.The assembly was rather simple due to the good instructions an the freetronics site and the detailed video. Because I’ve been a little impatient, the cube is not 100% rectangular. The first own skteches were no problem. It’s a lot of fun to view the colourful cube.
Unfortunatly I cannot upload sketches since yesterday evening. I’m in contact with John from freetronics. So a word concerning the support of freetronics: wonderful! Quick and competent.
The patterns are:
- drops: falling drops in different colours;
- lines: rotating diagonals;
- loop: a sort of a fountain;
- defColours: show all pre-defined colours;
- fill: all LEDs white, then change to random colours;
- plane: shift planes from bottom to top;
- single: random LEDs with random colours;
- RGBCube: show RGB values from #000000, which has coordinates (0, 0, 0) to #FFFFFF, which has coordinates (3, 3, 3). Red on x axis, green on y, blue on z;
- defColoursBlink: blink whole cube with pre-defined colours.
If this intro has finished, the patterns repeat in random order.
If someone has an idea how to make a better video, please let me know.
The first Arduino project off the breadboard. The eyes begin to glow if someone approaches.

Today (OK – last year – this a copy from my old blog) arrived the RedFly shield from Watterott. Here are some images of the soldering:
The main difficulties of the start were:
- Finding the MAC address. OK – the sketch WLANScan.ino gave the information.
- Finding the admin password of the router.
- Typing the correct password.
- Allowing the MAC address to join the net (lost the documentation).
But finally the WebServer.ino sketch worked:
