Hi NirL,Can you please tell me more, I am interested to know more about walkers.Alex

Entry accepted.Thanks again !

Hi Jude,Thanks for your suggestion about the sculpture contest !I entered the contest, it was accepted and I hope it will be accepted by the moderators soon. Creative thinking ! Keep an eye on the Sand Art Display, I am working on a second set of patterns....Draft names are Mad Ant, Message and Sine......

Hi Jude, thanks !I think there is no actual contest where I can submit my Sand Art Display....

Thanks Alex!Additional ideas for patterns are welcome !

Hi, in step 11 you can download the Arduino program for the sorting machine and a test program to set the color codes.😀

Thanks for sharing this library, very useful !Would something like this also exist for the MKR1000 from Arduino ?

Thanks !

Thanks !

Hi twit7503,I added a few steps with part lists and howto's.

Thanks Bverysharp !

Hi twit7503,the amplifier for the audio signals is a kit from Velleman, type K4001. If you google you will find it. It is a 7 Watt mono amplifier, I used a standard set of earbuds and limited the output with a 100 ohm resistor, as shown in the diagram. Basically you could use any other design too.The other parts (NE555 test signal and the wiring tester are built on standard prototype circuit boards with standard holes, as shown in the pictures. I did not design special PCB's..In the wiring diagrams you can find the type of parts I used.. For all resistors you can use 1/8 Watt types.Feel free to use other setups in a larger box for example, the design is not critical at all.I'm sorry but I did not make more pictures. I hoped the diagrams would be sufficient..
