Found on Flickr user Jmarler’s page, these EEPROM cufflinks are extremely beautiful. Soldered in place forever, these won’t be good for powering your Arduino but they could get your laid with a hot mom…

Truth be told, solder isn’t very pretty. I tend to chuck it in my toolbox and leave it there until I need it. I should really be more like these Flickr users that took solder-holding to the next level with empty dental floss containers. Very useful for the casual DIYer who isn’t using a mile of material a minute. Say that three times fast.

Soldering can be a really tricky thing to master. Between having to have a clean workspace, a nearby electrical outlet, and a huge risk for burns, it sometimes feels like an accident waiting to happen.

Luckily, there is a project that is easy, fun for the entire family and solder free. The Snap Circuit Rover allows you to easily snap together electronic parts to create a working remote-controlled vehicle. It’s truly a fantastic way to teach your kids about electrical engineering while building a toy that can bring your beer from the kitchen to your tennis ball couch. The manufacturer, Elenco, makes a whole range of robots and vehicles that don’t require solder.

If you want a good pair of headphones, it’s gonna cost you. No matter how much you spend on them, headphone jacks have a tendency of splitting from the wire and loosening, creating dead noise. When this happens, most people will have a period where they cry under their blankets in the dark, cuddling with their old pair, before throwing them out and buying new ones. No need to spend time grieving. This DIY shows you how to replace the jack all by yourself. Like a big boy.

The cost is minimal and all you really need is a starter soldering kit and solder. Other than that, this could save you some real cash. — Andrew Dobrow
