Gen 2 Photo Booth – Designing the Stand

After doing the initial measurements I decided that I wanted the booth to be adjustable and sit somewhere around chest height for the average user. This would be a standup booth when necessary and adjustable to a sit down booth. We spent a good $300 to buy the material to build it, but there were still many risks. Would it be strong enough? Would it be light enough? Would the slide rail even work? We already tried to build this with draw slides and it failed miserably. Hopefully we didn’t just waste our money.

Gen 2 Photo Booth – Designing the Optics


In a photo booth lighting is one of the most important factors. External flashes and umbrellas can give you an amazingly interesting look. Hot shoe flash diffusers can also give you a great look while keeping it compact. We know we can easily mount umbrellas using pole adapters, but what was the minimum size we need to allow us to use a standard flash?

Gen 2 Photo booth – Concept

Sometimes you build one thing and it snowballs into a something huge. My DIY wedding photo booth was one of them. It started as an innocent low cost photo booth and thousands of dollars later it became something great. After my wedding a lot of people were interested in my booth. I knew my Gen 1 booth wasn’t light enough or robust enough to loan out so I started to design a better one. This is how Cunning Turtle spent 2012.

DIY Photo booth – Recycling a Photo booth

After my wedding and my DIY photo booth was done I realized I now had a $500 dollar clunker I couldn’t rent or store. I decided to upcycle it into new things I needed after getting married. I built games and even a wall unit out of the spare booth parts.

DIY Photo booth – Booth Styles

So when I was researching photo booths for my wedding I found out that the old timey traditional booths were a thing of the past. Now new styles of photo booth technology are popping up. It’s hard to get good pricing when they are all over the map. In this post I’ll go over the different booths.

DIY Photobooth (Lessons Learned)

Last year I got married and I built a portable photobooth for my wedding.It was a hit and it had all sorts of fun features. It talked, printed it, and we had a lot of fun. I learned a lot of lessons after doing it. Hopefully some of my lessons will help anyone considering to building their own photobooth.

Servo8Bit Library version 0.6 released

The next version of the Servo8Bit library is released which includes the much sought after integration with Arduino libraries for the Attiny as well as other various improvements.

Here is a run down of what’s new:

  • Now works with various Arduino libraries for the Attiny45 and Attiny85.
  • Added support to run at 1mhz in addition to 8mhz.
  • Added ability to easily select if this library should use timer0 or timer1.
  • By default timer1 is now used. The old default used to be timer0.

Download the Servo8Bit library from its Github page here https://github.com/fri000/Servo8Bit .

ZIP button downloads all library files together

If you’re unfamiliar with Git Hub you should know that you can download all of the library files by click on the “ZIP” button, at the top left corner. Part of the download is an example program that shows you how to use the library on a bare bone Attiny. If you looking to use the Servo8Bit with an Arduino library check out this example, which shows you how to do just that.

When you use Servo8Bit with an Attiny Arduino library (such as the one found here) I recommended that you run the Attiny chip at 8mhz , instead of at 1mhz. The Arduino library uses it own interrupts (in order to keep track of time and what not) which sometimes fire at the same time as the interrupt used by the Servo8bit driver. The interrupts step on each other’s toe, so to speak. The effect is that sometimes the connected servo jerks a bit because the PWM pulse sent to it was too long. Running at 8mhz reduces this effect by a lot.


ATtiny45/85 Servo Library


Warning: Invalid argument supplied for foreach() in /home/atticdweller/cunningturtle.com/wordpress/wp-content/plugins/wordpress-flickr-manager/FlickrManager.php on line 335

Recently I worked on a project where I wanted to control a servo using an ATtiny85. I checked online for ready made code that did this but I couldn’t find anything satisfactory. Not wanting to switch to a larger microcontroller I decided to write my own servo library for the ATtiny85.

I call it Servo8Bit. It supports up to 5 servos, runs on the ATtiny85 or ATtiny45 and uses only one 8 bit counter. It can generate a servo control pulse from 512 to 2560 microseconds with 256 steps of resolution. And, most importantly, it is very easy to use.

Cunning Turtle Inc featured on the new DIY show JUNKies!

Ilya and I were just on a TV show called JUNKies. The show is centered around Jimmy and his amazing crew. Jimmy owns Freeport Auto Parts & Wrecking Corp, he gets all sorts of weird requests for parts and the show is centered around his crew trying to find rare hardware parts for crazy inventions. We helped out with a wireless project and brought our fire cannon for the episode that aired 9/1/2011 10pm Science Channel. It was a lot of work but we had an awesome time.


World’s Most Complicated Hit Counter

Hit counters are found on very site on the internet – though they barely go by that name anymore. Modern hit counters are invisible, fast and do more than keep track of the number of times a web page was loaded. Suites like Google Analytics record which geographical region a visitor is from, what operating system they use, and how much time they spend on the website.

The hit counter I built may not do any of those things, but it does keep track of hits, and in the most complicated way possible.
