3D PRINTING - IS IT A VALUABLE TOOL IN YOUR ARSENAL?

Okay, so a 3D printer may be considered a new toy or unnecessary luxury to some, but to others it's an indispensable tool for 'fab'ing up parts and prototypes. Do you use one as part of your hobby or profession? We noticed in our last workbench challenge that there were units sitting proudly on a few of your benches. Do you have one or access to one? Why or why not? What kind? How do you use it? Do you plan to upgrade as the technology improves?

What are your feelings - tool or toy?
 
 
Also, a big thanks to our new Cool Reads sponsor, 4D Systems. They were nice enough to pick up the tab on this week's newsletter. Be sure to check 'em out!

That's it, Enjoy!

POWER SOURCES: THE GOOD, THE BAD, AND THE UGLY!
 
With few exceptions, every electronics project needs a power source. It's what makes the electrons go round and round. However, not all power sources are created equal.

Hand-Wired Electronics
HAND-WIRED ELECTRONICS

There's been an odd movement in the music electronics industry toward hand-wired and point-to-point circuitry. We're talking terminal strips, solder tabs, and discrete components - no circuit boards or chip carriers.
