Deconstructed Piano - Or demolition by heat guns

A sort of sadistic deconstruction of a Piano. The patterns that are revealed while scorching the wood would be fantastic for an additional close up study!

Exploring Quora

Lately I've found myself using Quora more and more (https://www.quora.com/profile/Knut-Karlsen). Looks like an interesting place to be both to scratch professional itches as well as learn of interesting topics from knowledgeable people. It would be an even better place if we could get more traction from outside of the US.

Download 60 fps cloud time-lapse (1080p60)

Trying out some time-lapse recording again: This clip was recorded on a Canon Legria HF200 (i.e. nothing fancy) and processed in After Effects CC 2015. The raw material was quite noisy, even for a bright summer day, but the de-graining in AFX wasn't too shabby.

Are flexible solar panels finally catching up?

"Sun Cat" Batteries
A few years ago I documented a DIY project where I created self charging batteries using flexible solar panels. However, the batteries where just an experiment in evidencing; the art of make believe in realising new product concepts and evaluate said concept concept before any actual work is done. This experiment was part of my master thesis on how consumers could be encouraged to produce electricity in their own homes.

One of the key components missing at the time to make those batteries more than a mirage, where the lack of proper flexible solar panels. For some time there has been "bendable" panels available, but those where still attached to quite thick substrate.

Actual cells in use. Not too curvy, these are!
Now I find that researchers at +Stanford Engineering  has developed a method to peel off the thin film Photo Voltaic (PV) cells from its substrate and transfer them onto various objects, even those with curved surfaces. Their method includes soaking the panels in hot water to loosen the cells from the original substrate which sounds suitable for any DIY project.

The substrate is normally made of glass, not flexible, in solar panels. Substrate can also be made of special polymers (plastics) for thin film solar panels that are more or less flexible. The major new development, as far as I understand, is that the substrate is no longer necessary for the cells to function and thus can be removed. These new PV cells can be applied to non special materials and could give product designers new freedoms in adding powers sources to their products without compromising in their designs.

Maybe this technology could be used to produce tear off pages in a booklet for DIYers to stick on any odd project laying around? Sign me up for a couple!

Happy New Year!
