Die cutting machines

TopTenReviews of die cutting machines. Their top choice: Black Cat Cougar $749 “With 900 grams of pressure it will get through an amazingly long list of materials. The usual suspects are of course on that list – cardstock, vinyl, velum, etc. – but consider the family of projects you can create when your die cutting machine can carve precise shapes into rubber, leather, sponge and even faux fur. ”

solar indoor lighting for Baja living

Baja living encourages investigation of new solar technology. Paul at Zacs recommended a starting kit of 4 panels, 24 volt battery (Surrette Rolls are the best), an Outback power inverter and solar controller. This minimal system would cost $5000. A more appropriate alternative for those with limited need and resources is to use a Honda EU2000 generator to power tools and to use a small scale LED lighting system.

d.light S10 solar lantern

d.light S10 solar lantern

I ordered the d.light S1 and S10 solar lanterns. Both are in orange plastic with a stainless wire handle. I like the compactness of the S1 but the friendly lantern glow of the S10 also has an appeal. They seem to produce the same amount of light and I assume the battery life is similar. I also ordered the barefoot power firefly. I’m not as impressed with it at the moment. The main issue is the unwieldiness of a separate solar panel that connects with a long wire. Otherwise the firefly with 12 LEDs seemed to produce about the same amount of light as the d.lights. It was nice to have the gooseneck but overall is seemed like more of a toy and less of a tool. Barefoot powers larger light systems look interesting.

I’ll probably order a half dozen S1 and see how they fare. I would like to see a compact modular rectangular  solar lamp that you could daisy chain and control with a single switch. with larger panel and battery than the S1, perhaps a brighter lamp would also be possible.

How to Write a Book in Three Days: Lessons from Michael Moorcock

How to Write a Book in Three Days: Lessons from Michael Moorcock

In 1992, he published a collection of interviews conducted by Colin Greenwood called Michael Moorcock: Death is No Obstacle, in which he discusses his writing method. In the first chapter, “Six Days to Save the World”, he says those early novels were written in about “three to ten days” each, and outlines exactly how one accomplishes such fast writing.
