OCTOWS2811, Teensy 1.4 & JINX 64×32 LED display

Het gebruik van een octoWS2811 is de eenvoudigste manier om een LED display te maken zoals hierboven getoond.

Om dit goed te laten werken moet je eerst een Teensy module flashen met de juiste firmware.

Daarna sluit je de teensy aan op de OCTOWS2811 connectormodule.

In de RJ45 bussen van de OCTOWS2811 module steek je 2 LAN kabels en het andere uiteinde sluit je aan op de ingang van de WS2812 LED modules.

Het maximum aantal aansluitingen op de LED matrices of van de DIY strings van WS2812’s is 2×4=8 (Octo).

Download en start vervolgens JINX.

Sluit de Teensy met de USB poort aan op je PC/Laptop.

Sluit je LED matrixen aan op een krachtige 5V PSU.

Controleer je bedrading.

Definieer je WS2812 setup in JINX (grootte X*Y, type richting, zigzag of anders, etcetera) zodat de output al correct geformatteerd zal zijn voor je setup.

Start elke uitvoer en test het.  Indien niet OK, pas dan de setup aan van de LED matrix/buizen.


DIY windbelt for simple and free energy

A magnet is set into vibration as the wind brings a tightly stretched string or tape into resonance. The magnet is attached to the tape and moves in a coil of copper wire.  The coil is connected to a rectifier and provides energy as the magnet moves back and forth.

That’s the principle of the windbelt.

There have been some initiatives with windbelts around 2010, but you need quite a few of them to make a little energy.  And, of course, it has to be blowing….

Solutions have been made with large numbers of windbelts mounted in windows, in vineyards between fields, and also in areas where there is no electricity at all but the wind does blow.

If you combine a number of windbelts with a solar panel you can make fairly off-grid calls…. -)

Example of a window setup with windbelts:

Example of another DIY kit:

(We can supply this kit on request, we always have 10+ kits on stock)

Other DIY examples:

The theory:

Resonance theory with the famous narrow bridge @ Tacoma narrows that collapsed in 1940 , November 7th, due to the wind :


And another setup of a working windbelt:

Soldering aluminum

With an ordinary soldering torch you can solder aluminum with special rods, at a much lower temperature than when you can weld aluminum.  If you clean the materials with a stainless steel brush and preheat the materials well on, for example, a 4-burner stove, you can solder aluminum with an ordinary soldering torch (for tin).  I managed it and it is absolutely hard and tight!
