My TV is dead.

I have an Olevia LCD TV bought in 2008. For about a week, it would have no sound on any input after being turned on but a quick power cycle would fix it. Now it's stone-cold dead. No glowing LED on the power button like normal and it is definitely plugged in properly to a live outlet. What should I do now? [more inside]

No seriously, a large print Arduino would be great...

Back in the days of yore, my (almost) 77 year old father was quite the geek and maker, but never a programmer. Fast- forward to today and he can no longer work on big building projects and spends much of his time with his iPad and TV. We've been discussing what kinds of "doing" projects he'd like to work on, but the obvious contender of an Arduino is maybe a little difficult as I'm not in Australia to help him out with the programming side of things. What great projects have you known senior geeks to get into? [more inside]

Nerdy fun for kids in PDX

So I'm visiting my wife's family in Portland and just discovered that the electronics surplus wonderland known as "Wacky Willy's" went out of business several years ago. It was sort of like Archie McPhee's for Maker types. Are there other similar places that I can take my budding geek 12-year-old that are similar to Wacky Willy's? [more inside]

Help Me H4x0r My Xmas Lights?

I bought a few strands of cheap LED Xmas lights this year. They include a circuit box with several settings to make the lights flash in different patterns. The circuit box resets itself (to a new annoying setting) each time the lights are unplugged or when it shorts out in the rain, and I also suspect the box is the product's "built-in expectancy" (since otherwise LEDs might last too long to be profitable. Can I bypass the box? [more inside]

How many soldering irons can I plug in before blowing a fuse?
