Last January, I wrote about how to make your own traditional painted-leather “bomber” jacket, in a tutorial about how I made my Classic Lego Space Flight Jacket. Since then, several people have asked us for a future update post, to see how well it has aged after a year. And so, here we are. After a year of regular use, how well are those nifty flexible leather paints holding up?
The Hill Country Science Mill is celebrating its grand opening on February 14th. It’s a new science center in Johnson City, Texas housed in a historic feed mill built in 1880 as a steam grist mill and cotton gin. This picture of their WaterColorBot is from a preview day in November. A “Fall in Love with Science” event sounds like a great way to celebrate Valentine’s Day!
It’s citrus season around here, and that means marmalade. Whole cloves, cardamom seeds and cinnamon sticks decorate this sweet orange preserve and give it an aroma reminiscent of holiday desserts and spiced cider.
15 navel oranges
2 cups water
6 cups sugar
1 tablespoon whole cloves
1 tablespoon cardamom seeds
1 stick of cinnamon per container
The procedure is from our Marmalade Redux: peel the oranges and cut the peel into strips. Juice the oranges and put the strips of peel, juice and water in a pot to cook. Take the pithy pulpy parts leftover from juicing three or four of the oranges. Cut into smaller chunks and tie into several layers of cheesecloth or a cloth jelly bag (like this one) to cook in the pot with everything else.
After cooking for about 20-30 minutes, the pieces of peel should be softened. Remove the pith bag and put it in the cold equivalent of a double boiler: a bowl on top of a layer of ice that’s in a larger bowl. Turn the bag over every so often to help it cool down more quickly. When it is cool enough to handle, squeeze out a few tablespoons of the cooked pulp and pith through the cloth–this will provide the pectin that will help the marmalade to gel.
Put the pectin goo into the pot (which you conveniently left simmering on the stove) and add the sugar, cloves and cardamom. 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. Put one cinnamon stick in each storage container you’ll be using and pour the finished marmalade over it. Makes about four and a half pints.

It’s close to the holidays, which means people are pulling out their EggBots and getting creative. Last year, we posted a set of holiday designs and some tips for working with ornaments. Here are a few projects we’ve found this year.
Erin Ruppert made this lovely “First Christmas” ornament. The gold ink looks great on the clear ball.
Erin also made ornaments with ornaments on them, which somehow seems fitting.
Lotte made an ornament for her mom at FABKlas, a maker education program.
The folks at FABsterdam made this Mario ornament.
MAKE Ventura used gold Sharpie markers on a matte finish ornament to great effect. Other makerspaces are playing with their EggBots, too. The Johnson County Library in Kansas is doing Eggbot ornament tutorials in their makerspace.
Chris Lynas took the EggBot to “work and school Christmas fair raising money for charity – result: £200 in under four hours!”
Fran marked up eggs for a family igloo making craft party.
Lastly, our friend Miguel engraved glass ornaments with his EggBot.
In October, we released our Solderless Flickery Flame project, based on a tiny breadboard with six red and yellow candle-flicker LEDs, to give a fun and semi-realistic flame effect. Today, we’re releasing two new Flickery Flame Soldering Kits along the same lines, each of which has 6 candle-flicker LEDs, a little circuit board, and a battery holder.
The Yellow/Red kit has the same mix of yellow and red candle-flicker LEDs that works so well in the breadboard kit. This one will look great in a jack-o-lantern, luminaria, or scale-model fireplace.
On the other hand, the White/Warm White kit has a mixture of (cool) white and warm white LEDs that give a modern wintery flame effect that has at least as much charm, but won’t be mistaken for a natural fire. This one will look great in all kinds of winter holiday decorations, luminarias, and props.
Both the Yellow/Red and White/Warm White kits are fun, low-cost, self-contained, and easy soldering kits, which will be right at home both as stocking stuffers and as bite-size first projects for soldering workshops.
The Exploratorium is holding their annual member holiday party and shopping night on Sunday, December 7 from 6-9 p.m. We’re excited to be there to show off some of our kits, including the EggBot, which will be available for sale. You must be a member to attend (need an excuse to become a member?), and RSVP by December 4.
