PiCasso Design Challenge

164 posts
As a matter of fact, the Art-a-Tronic exhibition, subject of this long PiCasso challenge has closed its second edition at the Kolder Art Space in Gent. During these last four months – the adventure started on April 5th – I tried to join art and robotics. with the help of the friend and artist Lorenzo Merlo, sending a message of art for freedom together with the inspiring fictionary world of Star Trek. But Art-a-Tronic is an idea that is growing that got the attention of some very int ...
I am asking myself this question because at this point, I have a working prototype but in that process I have also come to some conclusions.   In terms of finished, I have completed the window frame, connected my security camera and demonstrated the project working. Based on the conclusions below, this particular project is completed but opens doors for a more advanced project.   In reaching this end point, the following conclusions have become apparent:   1. That in order to a ...
Introduction   Even more LEDs! This time it's back to conventional 5mm ones. I had the idea for this piece many years ago when I was working on LED signage and, finally, I've constructed it.   The Work   Here it is on a table in my workroom. Ideally it should have its very own plinth but I didn't want to stop and build one now so this will have to do for the moment.     The following video shows it working:     The camera splurges the light too muc ...

Success, I got my IP camera to connect to the PI and display full screen. I think my son is correct, this project would be even more awesome with a 4K video setup to make it look even more lifelike. After struggling to get the PI to read the video stream from the camera it was a great sense of elation to have it work. ...
While putting the final touches together for the window frame I had a great idea, one that allows me to not have to use any type of fastener on the wall, while still ensuring that the box cannot slip off.     I picked up some lace topper at the thrift store. The curtain rod I had to use is too fat to go through the top of the material so I need to find a thinner dowel. I threw it up just so I could get a picture of what the final display looks like. I am quite happy with how it look ...
So I laid on a light coat of paint to see how things would look. There are a few touch ups before the final coat, but it turned out pretty good. Have to complete the curtain rod mounts on the weekend and find some light curtains. My son made an interesting observation. My project could be applied to people living in highrise apartments. Rather than only seeing across to other buildings, a high def camera could provide the input for a nice backyard view.   ...

Trimmed and installed the last piece of the casement that acts as the window surround.  Added a little filler compound to make the joints seamless. Tomorrow night sand those down, and paint is on the way. I have run into a snag though. One of the display sources I was going to use was an IP security camera, but I am having problems getting the PI to login and display the stream. The camera documentation states that it supports RTSP but I have tried both Mplayer and KerberousIO and so far no ...
Hi,   While waiting for the magnets and laser module to arrive, I thought to experiment a little bit with 3D printeded lithophanes.   I found on Thingiverse a lithophane of The Great Wave off Kanagawa made by utoudabi: https://www.thingiverse.com/thing:2497763   I printed it using white PETG. This is what I got:     Also found a great tool to generate lithophanes from images: http://3dp.rocks/lithophane/ The tool is open source, so I think we should be abl ...
Finshed the back framing for the window frame and test sized it to the TV, not perfect but a little massaging will get everything looking good. A little wood filler on the cracks and a coat of white paint and then I just need to make the curtain rod. I left one side of the picture frame to show the construction and the pocket where the PI will live. I was elated to find that the remote for the TV works even though the sensors are covered. I was a little worried about that this morning when I was ...
First photos of hardware coming together. This is the inner bezel that acts as the window frame. It will sit over the front the the LCD screen to hide the entire bezel. A second frame the same as this but 3 inches wider and higher forms the outside of the window frame.   ...
Nothing throws a wrench in plans faster than unexpected problems, be they work or personal. The past couple of months have flown by and I am frustrated by a perceived lack of  progress. I am not finished, I do have a long list of designs that did not work out and I am sure I know what will, but I have to eek the time out of a schedule that is much busier than expected.  My original plan to use reclaimed items did not pan out so new materials have been selected. Even if I go overtime I ...
Update:   I have been working on this almost all day. I want to create the globe to look like a baseball. Trying to figure out an easy way to program all the lights to do what I want. I decided to try using Excel and transfering the cell value to Python. It works quite well, here is a photo of the excel program and the python script it helped me produce.       import board import neopixel import time pixels = neopixel.NeoPixel(board.D18, 72) x = 1 r = (242, 0, 98) g = (0, ...
These are some of the pictures of the current setup.                   There is a REST API server implemented using express.js framework.  Here is the code:   const express = require('express')  const app = express()   app.get('/', (req, res) => {   res.end('end'); }) app.get('/blue', (req, res) => {   const { spawn } = require('child_process');   const pyProg = spawn('sudo', ['pyt ...
Now is the time to connect lantern to the Snips Assistant and test if it works.  First, put the NeoPixel together with the Raspberry Pi controlling it inside the plastic lantern container (see earlier blog about how to make the container).  Currently the Pi has there python scripts which will turn on red, blue and green lights.  Other colors can be added later.  There is a REST API service implemented using express framework.   There isn't much needed to change to the S ...
I have reached the conclusion of the Picasso Challenge and I must say it has be quite a challenge journey!. I enjoyed so much working on this project where I learned tons of new things and it gave me the opportunity to stay in touch with awesome members of the Element14 community. I'd like to take this opportunity to present one more Hologram demo, hope you enjoy it!. Warning: The following video contains loud sounds   Bill of Materials Electronics Assembly Other 3D ...
