Where have all the parts stores gone?
If you're old enough to recognize the photo below, then you too might reminisce of the days when you could get repair parts in almost any town on many street corners. Of course, that's when things were designed to be repaired.
In today's climate of throw away tech, do you see the dwindling infrastructure of brick and mortar parts stores to be a hindrance to the advancement of hobby electronics or are online sources (including those from China) well suited to moving the body of knowledge forward?
And, be sure to check out this week's sponsors! Without them... well, you know!
That's It. Enjoy!

CONSPIRACY THEORY
The infrastructure for electronic experimentation is rapidly evaporating. Brick and mortar parts suppliers are scarce, and finding parts for existing devices is often frustrating. So, how do we turn this trend around, and keep electronics as a hobby alive?

BUILD THE RETRO REGEN RADIO
In the fast moving world of digital electronics, I find it incredible that the vacuum tube - a piece of early 20th century analog technology - has managed to survive. It should have bitten the dust long ago but that just did not happen. This back-to-the future one-tube radio is made with readily available parts, operates on 12 volts, offers amazing performance, and you can build it yourself.

CREATE THE ULTIMATE TALKING SKULL WITH THE WEE LITTLE TALKER
What do you get when you join a compact full-featured MP3 player with a powerful PICAXE microcontroller, a digitally controlled spectrum analyzer chip, and some clever programming? A talking skull that stands head and shoulders above the rest that utilizes the new Wee Little Talker control board.

GENERATING ANALOG WAVES FROM DIGITAL SIGNALS
Getting good analog signals out of digital ones can be done fairly easily with a minimum of parts. It does take some programming effort, and high-frequency audio signals require most of the uC clock cycles. However, if you experiment with these two general approaches you will probably find some interesting applications for your projects.
