Note that -- as I pen these words -- for a $12 pledge there's still an "Open-Source Special, DIY/Tinkerer's Kit" that includes two custom-fabricated, specially-silvered NeoLucida prisms so you can make your own camera lucida design!

I saw the Kickstarter project and with my interest peaked, headed over the Apple App Store. As they say, there's an app for that. $4.99. It does essentially the same thing.

I think I heard about that app -- but doesn't it just use the iPad's camera to present a faint image in the iPad's screen that you then trace around? I suppose you coudl then print this off and fill in the details. Have you used the app? Can you tell us about it?

One could connect a digital camera (or a computer with a digital photograph) to a PC projector. Projecting the image onto a piece of paper or a large screen would allow unlimited time for tracing and leisurely detailing of the image.

That's not a bad idea at all -- I could use this to amaze my wife with my (artistic) prowess

I use the Camera Lucida app. With my iPad. It works better than the traditional camera lucida, Art-o-graph, or any other optical image transfer tool that I have encountered. I, too, pledged on the Kickstarter campaign, and will receive mine in the first batch – I mainly did it out of curiosity, and add to my collection of traditional Camera Lucida's. Link for Camera Lucida iOS: https://itunes.apple.com/us/app/camera-lucida/id362499096?mt=8

Can you show us some examples of your work with the iPad App?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
