Frozen: Elsa Coronation Cape Stencils

The short story is that my niece needed a cape that matched Elsa coronation dress from frozen. Everything was going great till she pointed out that the cape has magical symbols on it.  So I spent 2hrs and digitally traced and outlined the symbols. From what her mom says, it makes it easier to iron on these shapes. Leave me a post or donate if you find this useful.

If you need high resolution files or need the MS Publisher File to make even more adjustments, leave a post and will get back to you.

Oh if you are making this dress... I highly suggest you check out Esty.com sites below. I found that came close to what I needed, but mom needed more details.

MultiTouch LightBox

LightBox

This proof of concept of the multi touch system not using IR technology and using the human eye viable spectrum 400nm-700mn. shadows from light(s) within the box will be capture on the 'glass surface' via the web cam. The Surface will need to use a diffuser with the correct oipacness to allow object (like fingers) to be recognized. This information will be process by a computer to do cool things.

Multi Touch ShadowBox

you don't know how good you kids have it...


Before the iPhone and touch screens, My friend and I saw this add for MS Surface. We loved the idea but didn't have $12,500 to buy one. However the NUI Group, was a open source project that showed how to make a multi-touch table. The 'Shadow Box' was first attempt at making a multi-touch interface.




Stage 1: ShadowBox
This proof of concept of the multi-touch system not using IR technology and using the human eye viable spectrum 400nm-700mn. Building two so Dan and Bob can play with them.


Phase 1  Research Gather Supplies needed

Items needed	cost	comments
2 usb web cams	~$10	being shipped
2 Glass/plexi	~$8	will buy
Box	free cardboard	have
Diffuser	free paper	have
Projector		don't need
IR gear		done need

Phase 2  Design/Build
Diagram 1: Shadow box design

Phase 3  Test Hardware/Software Setup
web cams is installed and have been calibrated (aligned and focused)
Software Calibration done (tbeta)

Phase 4  Develop Software
Successfully ran Photo Demo software
 
Phase 5  Review Improvements for next version
Pros

• Cheap to make
• Simple to make
• Would be easy to do large scale (maybe use sun as exterior light)

Cons

• exterior shadows cause slight problems with touch recognition
• exterior lights need for use (lights need to be positioned optimally)
• not very reliable as far as accuracy or consistent results
• No good way to read QR codes
• No good way to integrate display into the surface (using visible light)
• No or very little difference between hovering and touching surface

Improvement to current design

• Exterior lights
• learned that over head lights are better then light coming at sideways angle
• printer paper worked well, but paper was fibrous. This caused little dark spots for the web cam
• would like to use material that has consistent density (less fibrous)
