I feel like John Denver saying that! ;-) One of my favorite singers by the way... The last time I saw him was on stage in a very small venue in Fort Worth just a few weeks before he died in his plane. :-\ One of my favorite songs of his is Shanghai Breezes. :-) And speaking of that song... I wanted to take a moment to wish a special friend of mine a very Happy Birthday! :-) I hope it was a good one for you! :-)

This shot shows another one of our Chip Camp volunteers. Alison Jensen also came from California to help out with Chip Camp this year. She is a specialist at programming the microcontrollers we used for several of our learning activities and here she is helping one of the students get their program working correctly.

Every since Pacman had his revenge on Blinky, Pinky, Inky and Clyde, in a good ole Texas style ambush, he has been getting bored and chasing Space Invaders around the yard! It has become a chore to try to keep him in line! Something is going to have to give sooner or later!! ;-)

The Rings of the Olympic games! Well, the Rings are suppose to include a White background and a black ring in the center but those got swapped in my photo for some reason! ;-) And I didn't even do it in Photoshop! Ha! And yes, my white ended up a bit on the pink side due to having to take drastic measures to tone these bright a$$ lights down!! ;-) Not a bad line up either considering it was all done by hand with nothing to help me position the rings! ;-) Anyway... all of the colors of the Olympic Rings are represented here and it is said that at least one of these colors can be found on the flag of every nation in the world!
So here is my entry for the Light Painting Competitions and Themes Group July 2012 Theme of "Olympic Rings"
I couldn't stand to see jah~'s entry sit out there by itself for yet another month! :-\ So come on LP'ers! Get out there and make some rings! Or make some ringing in someone's ear at least! ;-)

The paintings in the Museum decided to take the night for a walk in the park. Lucky for Cameron he was there to witness it. ;-)
Okay... Expanding on ~jah's idea a little further... Some of you that know me may recall that one of my goals was to paint the Mona Lisa in the air! Well... thanks to Phil's Code Generator for the Digital Light Wand, that goal has been met! ;-)
Some of these are instantly recognizable and some not so easy to figure out. Are you up for a challenge? Let's see who can guess them all correctly! ;-) (I gave the easiest one away already! ;-) ) I won't reveal the answer until someone gets them all correct. :-)

Another 3-valve creation. The first drop was colored grey, the second green and the third red. I like this color combination..
More drops & setup on my website:
7-Segment-Anzeige Grove TM1637 mit Microcontroller NodeMCU LoLin V3 ESP8266. Es wird über WiFi eine Verbindung ins Internet aufbebaut und von einem NTP-Server die aktuelle Uhrzeit geholt. Danach zählt der Prozessor selbst weiter und zeigt die Uhrzeit an.
Nachdem es technisch funktioniert hat, habe ich selbst aus Klemmbausteinen ein würfel-förmiges Gehäuse gebaut.
Yes, my soldering is nasty, but it works.
From bottom to top: D1 mini, DIY-shield to connect the 4-digit-display, the RTC-shield.
This one I like very much. The fact that the bullet is "under the umbrella" makes it appear so 3-dimensional.

Just for fun! ;-) And I have to credit - Hob - with the title due to a tag that he added on THIS PHOTO a while back! ;-)

This is a technique I have been wanting to try with the light wand for a while now. These were created using the Digital Light Wand on wheels, with the LEDs pointed downward just above the pavement.
One of the neighbors walked out of their house as I was wheeling this contraption down the street! Now they KNOW I'm nuts! ;-) Ha!

In a way! :-)
I just arrived back home from my trip to El Paso and wanted to get this out there tonight to hopefully meet the deadline for the LightPaintingPhotography.com website contest.
Now that I am home, I will be able to get back on getting costs together for the Digital Light Wand and return all the inquiry emails on that. And maybe fit a little more LP in this weekend! :-)

Arduino UNO was one of the first ever circuit portraits, way back in 2013. This is a new edition with an extra layer and a bit more finesse.
Listed on Etsy here: www.etsy.com/uk/shop/uptomuch?section_id=10073316
This is my first collision with the new setup I did, using a cheap electrovalve I bought. I dropped each drop using a button connected to the valve.
I plan to make a DIY "time machine" to regulate the time between drops with a microcontroller, but I'm too lazy for the moment :P
Thanks for viewing!
The DIGITAL LIGHT WAND Tutorial is now complete!!!
HOW TO MAKE YOUR OWN DIGITAL LIGHT WAND!!
(aka The Programmable Light Strip)
Alright Everyone! After some long hard hours creating a VERY detailed document on how to do this (and creating a How To Video as well!), here it is, as promised! Many have asked me how this was done over the past few years and I quite honestly did not have the time to spend with many individuals in explaining how it was done or supporting any problems that might have come up with others trying to follow a quick how to lesson so I was hesitant about getting any information to anyone. Now... With the Help of blacklodge!, Dennis Calvert, and Garnatha giving me feedback on the instructions during the process of building one, I have now completed the tutorial and I am ready to show everyone how it is done. This documentation has been a year and half in the making!
You can find get the detailed information on my personal website under the new Tutorial Blog at:
I would love to hear any feedback you have on it and if you do decide to take on the task of making one, I would love to see what you create with it as well!
ENJOY!

For those of you that do not think you can take this project on or just would like to get it in Kit form or fully assembled. I am considering setting up shop to do that for a reasonable fee if there is enough interest. I really was not looking to market this or make money on it but I am trying to figure out way to get it in others hands that are not the DIY type. :-) Just drop me a Flickr mail and let me know or leave a comment.
Thanks,
Mike

Amsterdam Light Festival
Amsterdam Light Festival is an annual light art festival in Amsterdam. Artists, architects and (light) designers from all over the world bring their light artworks and installations alive during the festival every winter. The artworks are placed alongside two routes. Each route has their own theme, set of artworks and visitor experience. Water Colors, the boat rout, displays big monumental objects and offers visitors the chance to experience the art from a water perspective. Illuminade, the walking route, shows interactive and innovative installations from upcoming designers in the Plantage neighborhood.
Celebrate winter, with art, light and water!

Living Pods
Artist: Anouk Wipprecht (designer)
Location: Garden Hortus Botanicus
The human body is strong, however, it cannot do everything we want on its own. Luckily technology is developing more rapidly than ever and opportunities to adopt qualities from living organisms are presented nowadays. High-tech fashion designer Anouk Wipprecht takes advantage of these possibilities to show us that human beings and nature can establish a relationship that is more symbiotic.
With Living Pods, that reminds us of the same style of her interactive 3D printed fashion garments, she has created an artwork that is also a robotic light accessory. The white lotuses stand for purity, inner growth and the connection with the universe. They are made water-repellent with the same technique used in aerospace, aviation and diving.
What is missing in contemporary fashion? Microcontrollers, according to the Dutch Anouk Wiprecht. Anouk works in the so called emerging ‘Fashion-Tech’, a rare combination of fashion, design, engineering, science and interaction design. Wiprecht creates technological couture where her design moves, breaths and reacts to its surroundings. Wipprecht uses special sensors for this, that monitor the space around the wearer, but also detect stress and anxiety in the wearer him or herself. Through her creations she explores how we can communicate with the world around us through our wardrobe.
Everyone smiles in the same language! :-)
Just a little way of spreading Sunshine everywhere! :-)

It has been raining pretty hard here for the past few days. I think we received somewhere around 5 inches yesterday evening in a very short period of time! It was coming down hard! While that was going on, I was working on a new orb tool that I have been wanting to put together for a while.
Introducing the Programmable RGB LED Orb tool! Arduino Microcontroller driven and able to produce a range of 2 million colors! :-)
I still have more plans for this in the future, but this is the first step in testing it out. Something appropriate to follow the rains. :-)

3 drops into water with a few drops of rinse aid and red ink. Xanthan gum/water with red ink in the drop.
Settings:
Exposure - 1/200sec
F-stop - f/16
ISO speed - 200
Speedlite - 1/128
Here's a super-simple single-leaf shutter I made this week. It's actuated by a tiny 5V solenoid, controlled by an Arduino Uno microcontroller and some assorted electronics. Shutter speed can be controlled using a small potentiometer, and the shutter is triggered with a tactile button.
I'm hoping it will find a home in a simple Holga-like camera, albeit with a much smaller microcontroller (like an Arduino Micro or a Trinket), and powered by a single 9V battery rather than a big pack of AA cells. So far it looks promising - I have it programmed here for 1/125s down to 1s plus Bulb. Whether or not it actually can muster 1/125s is debatable- but it looks promising to me :)
I tried some drops in a small espresso cup to see if I could get anything decent. I couldn't quite grasp it tonight for some reason. This is the closest I got to anything.
3 drops of refridgerated xanthan gum mix with some yellow food dye dropped into the same mix with blue food dye and a little Dettol power and pure kitchen.
"Just like Begger's Canyon back home!" Young Jedi Cameron in his "Mini" X-Wing Fighter taking on the massive Death Star ahead! ;-)
Camera set up on the tripod between the front seats of Cameron's Mini Cooper S. Started the Exposure with the dash lights on and used a white LED Key Light to illuminate the steering wheel and Cameron's Arms and hands. Then covered the lens, turned off the lights inside the car and used the programmable LED light Strip in front of the car to paint the image of the Star Wars Video Game. Red and Blue LED Key Lights were used pointed straight at the camera to get the bright star bursts. 28mm, 140 seconds, f/22, ISO 200

First test run of the CD-sized rotor with the Arduino generating three-note polyphonic music. There are four reflective opto-sensors, mounted above a CD with a paper disk on top.
Playing around a bit more with the Programmable RGB LED Orb Tool tonight. I said it has a 2 million color range... but the colors on the dark end of the scale really do not stand out very much at all. I suppose they would work okay with a higher ISO, but then they would just be... well, brighter! :-) So maybe I better scale that statement back a bit. Probably more like 1 Million usable colors! Think I should toss it!?
Is there anyone that would like to see a photo of the tool itself? Or how about a tutorial on how to make one!?

A DIY mini-LED menorah for hanukkah. These are "regular" size, 5 mm diameter LEDs; they take up a lot more room than that tiny chip does.

Prototype of a Bluetooth LE controlled lights and train switch.
Here using a BLE microcontroller HM-10 to control 6 LEDs and one PF motor.
The motor and lights are driven by 2x DRV8833.
Using two wire signal lights, where the red and green LEDs are wired in reverse parallel.
The app is made with MIT App Inventor.
This solution is being discontinued. Will replace the HM-10 by a nRF52832 with much more autonomy.
This controller and DRV8833 are all few dolar/euro components!

Getting MUCH closer! Phil Wright sent me a new version of his program today with some tweeks in the color area and it is so close that I HAD to post this! This is close enough to my goal that I would have to say that it is met! Of course there is always room for improvement but just how close one can get using a programmed strip of RGB LED lights? I think not MUCH closer... but still possible I guess. ;-)

2 drops into xanthan gum mix, some blue ink and a little Dettol kitchen cleaner.
I decided to have a go at a mirrored thingy in post process once I had removed the usual stray splashes and a little mess on levels.
3 drops into a bowl of water/xanthan gum mix with a few drops of Dettol Power and Pure multi purpose kitchen and green food dye. Water/xanthan gum with red dye in the drop.
Tonights wonky Donkey 4 drop splash of orange dyed liquid into a green dye base liquid. The wee box is certainly doing what I built it for.
“Claremont Road” has five Arduino UNO microcontrollers which control train movements along with PWM (servo adapted) points/turnouts, and signals according to pre-written programs or “sketches”. This is a completely different concept from DCC.
The master co-ordinating UNO gets feedback from the track through 14 enbedded infra-red proximity detectors,
Slaves 1-3 are UNO “train drivers”,
Slave 4 handles the display and lights. The orange display shows the current mode and commands being passed between the UNOs via a short-wire protocol known as I2C.
they would pass on the "Take us to your leader" thing! ;-)
