What is a prototype?

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.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

 

A new type of thermal scanner  

Scan surfaces for thermal variations using the deltaK, a new type of thermal scanner that offers much of the functionality of a thermal camera but at a much lower cost, and small enough to fit on a keychain.  

The deltaK is perfect for troubleshooting circuit boards!

Thermal variations tell you alot about whats going on in electronics. By sweeping the deltaK over a circuit board you can quickly pinpoint hot spots and variations which can tell you which components are bad or malfunctioning. When you're done just toss the deltaK in your toolbox, its durable, no need to worry about your smartphone or an expensive thermal adapter or camera.

 

 The deltaK indicates temperature using sound   

As the deltaK is moved over a surface, it emits a tone which changes in pitch as the temperature being scanned changes relative to the starting point of the scan. This makes it easy to find temperature variations on a surface, which would normally require a thermal camera.  

 

Multiple sensitivity ranges  

The deltaK has three sensitivity ranges, which allow it to be used on surfaces with large or small temperature variations. For instance, the least sensitive range could be used to scan an automotive cooling system, while the most sensitive range could be used to scan a wall for hot or cold objects beneath the surface. Even a change of 1°F can be easily heard on the highest sensitivity setting. Under some circumstances this is sensitive enough to detect wood studs in a wall.

 

The deltaK measures all temperatures relative to a starting point.  

A very important feature of the deltaK is that all temperature indications are made relative to the starting point. When the deltaK is activated, it immediately measures and stores the temperature being scanned. All further measurements are indicated relative to this starting point, until the power switch is released.  

A powerful tool for home and work  

 

 

 

Development  

I've been using the deltaK in a prototype form for nearly a decade in my engineering work. To make it available to everyone, I'll make it keychain sized. By splitting the circuit board into 3 pieces and stacking them on top of each other to save space, I can fit the circuitry into the new smaller keychain sized housing. Also, switching to button cell batteries will save a ton of space. I've already verified these changes are realistic using CAD and there should be no problem making them happen, I just need your support!

 Production   

I'll allow myself a generous 2 months to finish reorganizing the circuit board to fit into the smaller keychain sized housing, and arrange for the housing itself to be produced using either silicone or aluminum injection molds. Then an additional 4 months to actually produce and assemble each deltaK scanner for you!  

One more thing  

One of the great things about the deltaK is that it is inexpensive, which means your average Joe can save some money for other things. That is a good thing. But an even better thing is that this means people who could never afford a thermal camera could now have a tool with much of the same functionality. Students and engineers all over the world could benefit greatly from an affordable thermal scanning tool. Who knows what sort of uses people will find for the deltaK? Your support is greatly appreciated! Lets bring the deltaK to life!

Risks and challenges

The deltaK scanner design, from the housing, to the circuit boards, has been optimized for manufacturing in low volumes. Most components are very common, and those that are critical have had multiple sources located.

I have added a generous amount of time to the production schedule for the deltaK. By the time the campaign is over I will be able to focus exclusively on manufacturing the deltaK.
