Lemon Plum Jam

plumjam-1

The plums on our tree ripened all at once this year! Making this sweet and tart Lemon Plum Jam took care of some of the excess fruit in a tasty way.

Ingredients:

  • 4 cups plum pieces (pits removed, skin still on)
  • 2 whole lemons—large meyers if you can get them—cut into pieces (seeds removed, peel still on)
  • Juice of 2 more lemons
  • 1/2 cup water
  • 4 cups sugar

Heat the plum and lemon pieces, lemon juice and water in a pot on medium, stirring occasionally. After about 15-20 minutes, the fruit should be softening. Macerate the fruit in the pot—a potato masher works well for this. Add the sugar. Stir regularly and cook to the desired consistency. To test consistency, put a spoonful on a plate in the fridge. If it’s too runny after cooling for a few minutes, keep simmering and test again after a few minutes.

Makes about 2-3 pints.

If you want to can it for longer storage, Ball has a nice introduction to canning (pdf), and additional resources on their website.

We had a visit from one of our favorite art cars, the LEGOJeep. Our friend Kevin stopped by to work on some parts to infuse even more LEGO spirit into the Jeep.

We also had a couple of young visitors stop by to see what we were up to. Above, learning to use the laser cutter and calipers.

Very proud of her contribution to the LEGOJeep!

 

 

WaterColorBot and BeetleBlocks

The Tinkering Studio posted on twitter:

BeetleBlocks is a system for enabling people to explore algorithmic 3D geometry by snapping together Scratch-like programming blocks.

They posted a picture of the finished painting, which looks awesome.

Computationally Fabulous Scarves

Our friend fbz just launched a kickstarter campaign to create algorithmically generated scarves, each one provably unique.

KnitYak scarves ship with the specific code and generating key used to make the pattern on your scarf. There is something powerful about knowing the mathematics and code behind the pattern you are wearing.

She’ll be getting an industrial knitting machine for her company KnitYak to automate the process of manufacturing these individualized creations.

Look what just arrived in the mail– Blinky AVR Earrings!

Blinky AVR Earrings

Not long ago, Rick posted on twitter about the ATtiny84 blinky earrings he had made, inspired by my voltage regulator earrings (which I now fasten on with the appropriate phillips screw).

Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.

Thank you, Rick! I know what I’ll be wearing to Maker Faire!
