DIY Life

Back in September of last year, I wrote a comprehensive tutorial for making marble magnets, an easy project in which images are placed under little glass bubbles in a way that really makes them come alive. In that post, I mentioned that the image pebbles could also be used in other projects, like concrete mosaics.

Kathy Cano-Murillo, one of my favorite craft gurus, recently posted the kind of mosaic project I was talking about: Concrete Coasters. The process for making them is similar to making a mosaic tabletop or paving stone, on a smaller scale.

After creating the image marbles, you mix concrete and pour it into coaster molds, then embed the marbles in the molded material and allow it to dry for at least a day. After removing the concrete coaster from its mold, you varnish it to seal it, and add felt padding to the bottom; if you like, you can further decorate the coasters until you end up with something like Kathy's results.

The one thing I would do differently than Kathy? I don't think white glue (also called PVA glue) is the best thing for gluing images to marbles; glass isn't porous, and that kind of glue is most appropriate for porous materials. I recommend using E-6000 glue instead. However, the fact that you're sealing the marbles in concrete probably makes it a moot point.

Everyone needs coasters, right?

A set of Scrabble tile coasters were recently one of Craftster's featured projects. They're simple, requiring more patience than time or skill. The creator, Jessfun23, glued Scrabble tiles to thin cork sheets in clever drink-related patterns, then coated the tiles with a sealant.

She chose Mod Podge, but any waterproof, non-toxic clear sealant should be OK. Some sealants might yellow over time, but there's no ideal soft base for coasters that won't deteriorate over time anyway (most coasters have a finite life span by definition). Another Craftster user, TracyinNH, was inspired to try this project with a felt bottom and denim edging, for an entirely different look. You could try running a metallic gold paint pen around the edges before applying the sealant, or edging each coaster with glue and glitter. The possibilities are endless.

Acquiring the letter tiles for this project is probably the largest obstacle to hurdle. I did some research, and was able to find some surprising and interesting options... not just for sources of tiles, but also for the look of the tiles themselves. There's even a totally different way, shown in the photo above, to make a similar coaster. You'll find something for almost everyone, including your favorite l33t g33k, after the break.

My Tupperware cupboard is a scattered collection of mis-matched containers and lids. Cleaning it out, I found far more lids than containers. Typically, I would just get rid of the extra lids, making a collection of matching containers. Lifehacker points us to these top 12 uses for plastic container lids.

Little round lids make great coasters for kids. You could use the slightly larger ones as plant coasters, keeping water from dripping outside the pot. Toss aside the abrasive scrubbers, and use a plastic lid to scrape your pots and pans. they are strong, non-stick and won't damage things. The crafting options are endless, like using lids as paint pallets, glitter, or bead holders or as a protective piece to catch glue gun drips.

Have you re-used stray container lids? Tell us how!

Circuit boards don't belong in the landfill. They can be dropped off at your local recycling depot but before you do that, try your hand at recycling them into something useful. These 10 creative ways to reuse circuit boards are sure to inspire your creativity. While they've also been turned into consumer products, go ahead and make your own. A circuit board business card case will help keep you organized. The photo frames or coasters would be fun projects, and would make a great Christmas gift for the computer geek in your life.

If you still have more than you know what to do with, and you'd take huge pride in being known as the guy with the geekiest ride then this circuit board car is your ticket. You are sure to turn heads in this uber-geeky automobile decorated entirely from recycled circuit boards. While nothing quite compares to Jason's homemade wooden spoilers, this circuit board car comes awfully close.

Our sister site, Engadget, has a post about a coaster project from Evil Mad Scientist Labs.

These coasters are made from the photomasks used in semiconductor manufacturing; the patterns on the photomasks are etched into the components in the factory. The masks are solid glass with a thin metal design applied to them. You can get them from retailers who deal in electronics surplus.

Be sure to check out the comments on the Engadget post, where readers discuss safety issues and sources for the materials. It's useful to know, for example, that shattered quartz glass is unusually sharp -- and difficult to remove from a cut. The reader suggests backing the coasters with clear plastic; I suggest keeping them away from small children.
