A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
What is it?
The Chroma Chrono is the worlds first programmable multi colour camera flash, which allows you to take some pretty cool pictures like this:
Or how about this:
Or maybe something really weird like this:
All of the above was done in camera, no photoshop required! But how does it work?
How does it work?
The Chroma Chrono is a programmable RGB flash, which allows you to flash multiple colours for set amounts of time over a long expsoure. creating the weird and wonderful effects, its as easy as 1,2,3:
Connect to the Chroma Chrono over wifi, you can do this from your phone, tablet, laptop, mac, PC, anything with a wifi connection and a web browser. Use the built in web page to set which colours you would like to flash and for how long and click save!
While you are programming it you can check out how the colours look so far by either triggering it through the website or on the Chroma Chrono's test button.
Step 2: Attach it to your DSLR's hot shoe and set your camera to a long exposure, turn off the lights.
Step 3: Fire your camera and move about, you can either move the subject or the camera to get strange and interesting effects, maybe something like this:
There are lots of ways to use Chromo Chrono, you can try moving the subject, moving the camera, moving the flash, zooming in and out, why not try it in black and white? The only limit is your imagination!
Check out the video below to see how easy it is to change colours and program the flash:
The Chroma Chrono uses a high intensity RGB LED which is controlled by a wifi enabled micro controller. The Choroma Chrono is powered by 3 AA batteries, either Alkalines or rechargeables.
The secret to its power is the fact that we can get much more power out of the LEDs by running them at high voltage stored in a capacitor inside the flash (like a regular camera flash) and running them with high current but for a small amount of time. The microcontroller makes sure you can't run them for too long but if you do get carried away the LED bulbs are easily replaceable by the end user.
The Chroma Chrono attached to your camera using the hot shoe found on most high end cameras and DSLRs, so as long as you have a standard hot shoe or an adapter to use one then it will work with any camera. It also works with both digital and film cameras meaning you can get great colourised photos and these weird effects on film too! The Chroma Chrono also has a Prontor-Compur adapter so you can trigger it externally using the appropriate cables.
I've spent the last 4 or 5 months working on the project in between the day job, and have gone through 4 rounds of prototyping so far:
Left is the first proof on concept, the second is the Chroma Chrono electronics in an off the shelf flash for functional testing purposes, the third is the first design prototype, and the right hand unit is the final fully functional prototype:
The Chroma Chrono comes in a die cast aluminium enclosure with an aluminium "Hot Foot" to connect to your camera, which also has a small button to test fire or to manual fire if the flash isn't connected to the camera. The case is painted with a lovely rough and touch black finish, and comes with a laser engraved Choroma Chrono Logo proudly on the front.
From the back we can see the Hot Foot also has a Prontor-Compur connection for triggering the flash externally. You can also see the power switch and the LED which indicates when the flash is fully charged.
I've decided to keep it simple and offer two rewards, the first ten early birds get a £20 discount but otherwise its £140 for one Chroma Chrono, and two for the bargain price of £280 and so forth. I didn't want to go down the merch route as it means I have more time to focus on the design and manufacture of the Chroma Chrono and less time making T shirts!
Risks and challenges
So far things are looking great, I've been through about 4 or 5 months of prototyping and testing, I've got a final production prototype, and its really just a case of how many we need to make.
As my day job is as an electronic engineer I've got a wealth of experience in producing electronic circuits and assemblies, and already have good links with a number of manufacturers both domestically and abroad, I've got everything costed up and ready to go. Saying that, this is still a kickstarter which has it's own inherent risks, but through due diligence and good planning, all of these can be mitigated, ensuring a smooth and successful Kickstarter!
