TKJ Electronics

Last week I recieved the Arduino Ethernet Shield – http://www.arduino.cc/en/Main/ArduinoEthernetShield
There were all ready complete examples provided, so it was very easy to get started.
Then I thought it would be nice to have a Ethernet DMX Controller, so i could type the IP-Adress of the Ethernet Shield in explorer, and from there control my movinghead (Stairville MV250H). 

Then I found this page showing how to use an MAX485 and the Arduino as a DMX interface – http://iad.projects.zhdk.ch/physicalcomputing/hardware/arduino/dmx-shield-fur-arduino/
I tried it, and it worked 🙂 – And the Arduino could communicate with my movinghead.

Then I combined the Ethernet example and the DMX example, to make a HTML Page where i could click on different buttons to change the DMX values that would be sent to my movinghead.
Try it out yourself… You need a MAX485, follow the link above on how to connect it to the Arduino. Just use pin 3 instead of pin 11, as the Ethernet shield uses Pin 9 to 13!

At the moment we are only two adminstrators who also writes the articles.
We would like to have other electronics-interested to write some articles here on the TKJ Electronics blog.

Simon, the other adminstrator has got a Graphical Designer to make us a new layout, which would be published when it’s finished!

But please write a comment to this post if you would like to help us.

Yesterday i started my development with Microchips 24FC1025 EEPROM.
I have successfully connected one 24FC1025 to the PIC16F877A, but i will try and connect 4 of them, which is the maximum.

I’ve also got my SD Card holder soldered so i could use it. I’ve connected the SD Card to the PIC18F452 and made some code in mikroBasic, using their SD library. I’ve successfully made a logging code, and a piture manager.

Finally TKJ Electronics is here.

My name is Thomas Jespersen, and I’m going to tell and teach you a lot about different electronic projects, including the PIC (Microchip).

But right now this blog is quite empty, but take a look at mikroElektronika’s forum
