Vintage Repair

I’m in the middle of overhauling a vintage Singer 201-2 sewing machine, manufactured in the US in 1940. As I expected, the motor brushes need replacing, the oldfashioned leaf switch controlling the light is — at best — intermittent and needs a good cleaning, and the cottoninsulated wire is begging to be updated to fireproof silicon insulated wire. Old appliances — void of microcontrollers or even simple semiconductors — are a pleasure to tear down and rebuild. They’re fun as a solo weekend project, or, if you have someone you want to teach basic mechanics and electricity to, they make a good two or three weekend project. Even bringing an old toaster back to life can provide a sense of satisfaction.

Bling Up Your 4th Of July With A Set Of Custom SMT Earrings

Of all the articles I have written, it seems that the most popular one was the December 2014 Christmas Earrings project. I received a ton of emails asking me to make other types. I thought it was interesting that the version designed using a microprocessor and surface-mount (SMT) components was far more popular than the simple one using through hole parts.
