New Books From Lindsay!

Check out these new offerings from Lindsay Publications.

	Another gem from Hasluck's "Work" series from almost a hundred years ago. Electricity was a cutting edge technology, but motors and generators (then called dynamos) were expensive. Here are a collection of articles from "Work" magazine of which Hasluck was editor describing how to build your own equipment. Click here to order!
	"A practical manual on model steam engines embracing information on the tools, materials and processes employed in their construction." Click here to order!
	If you really want to explore photography, build a camera. It's a great marriage of woodworking, metal working, an understanding of optics, the chemistry of photography and the creativity of an artist. This series of articles will show you how to test photographic lenses, build modern half-plate cameras, whole-plate and studio cameras, hand and pocket cameras, ferrotype (tintype) cameras, stereoscopic (3-D like Viewmaster®) cameras, enlarge cameras, make dark slides, exposure shutters and even camera tripod stands.

	Experimenters notes on Vacuum Tube Substitutions, Inexpensive Tube Power Supply, Grid-Leak Detectors, Regenerative Receiver & more! Click here to order!
	"Tricks, tips and secrets to help the builder of simple radios and electrical gear achieve high performance at minimal cost!" Building radios (and transmitters and antenna-tuners if you have a ham radio license) it about matching the proper capacitors with the proper coils to get a desired frequency. You can wind a coil and hook it up to a capacitor, but how will you know if it's right? A grid-dip oscillator, or gdo, is a measurement device that will tell you. And it's very simple - first used in the 1920's. Click here to order!
