Let’s wind down the weekend with some projects that didn’t quite warrant their own feature, but we think they’re still worth a look.

First up is a quick tip on cracking the lids on those hard to open jars of food. [Jason] says just grab about a foot of duct tape and the lid will come flying off. And while you’re searching for that roll of tape why not grab some foil tape to build a cooking oven. [Gabriel] built this solar oven by covering curved wedges of cardboard with foil tape and combining them to form a parabolic reflector.

Next we’ve got a trio of hacks that will come in useful in your home shop or at the┬álocal Hackerspace. Organization is key, and here’s a resistor storage system that uses #6 envelopes [via Reddit]. Also useful is the tip from [Felix] about using a tile saw to get clean cuts on your circuit boards. And if you’ve ever been plagued by a laser cutter job that doesn’t fully sever the material [Dan] wrote a guide on using a fence so that you can reposition the piece for another run.

Finally, we’re hoping we weren’t the only ones that didn’t realize the Raspberry Pi has an unpopulated footprint for a reset button. Now we’ve got to figure out if it’s okay to leave the PSU plugged in (based on it’s current consumption while the RPi is in power down) and hack together some sort of TV-based reset circuit for our RPi XBMC setup.
