We found a remake from our project Make your own 1952 Fraction-of-an-inch Adding Machine on display at Xerocraft, a hackerspace in Tucson. They cut and engraved the calculator out of hardboard using their laser cutter. It’s sturdier than papercraft and it looks great!

Cool Tools Podcast: Windell’s Picks
Our co-founder Windell Oskay is the guest on Cool Tools this week, and talks about some of his favorite tools, ranging from pencils to soldering irons. You can read about them or listen to the full podcast.
Another take on Twisted Wire Bundles
Steve W. wrote in to share his improvement on the method for making wire bundles we wrote about:
I’ve used the bend-it-over-and-stuff-it-in-the-chuck approach, but was not fully happy with it.
So I drilled a 1/8″ hole in the back of a binder clip. The drilling is easy if you clip a ~3/8 scrap of wood.
A 4-40 SHCS screw long enough to allow me to actuate the clip was not threaded all the way to the head, so I used a 1/4″ spacer between the binder clip and the 4-40 nut. (Pan head screws are usually 100% threaded, but I would have had to look in the dreaded ‘other’ box to find one of those). Having the nut up against the chuck acted as a lock-nut. I had been surprised when I first tried this that I did not have to work harder to keep it from loosening. I had expected I might need a lock washer, and/or a second nut to lock the first.
Just grabbing the wires with the binder clip (my original plan) was not secure. So I wrap the wires 180 degrees around a screwdriver bit and put that in the clip.
Works great, and it is quick to pop in and out when twisting many groups of wires.
Thanks for sharing your hack and sending the photos!
Lunch bags with the WaterColorBot
Spencer posted on our facebook page:
Thought you might enjoy this photo showing the WaterColorBot in action while inking some custom “brown bag lunches” for summer camp.
Final results…
And here is another. Fun project!
They look great— thanks for sharing them with us!

BUILD SOMETHING THAT MATTERS
The creative energy and years of experience found in our huge community of Hackers, Designers, and Engineers is waiting to be unleashed. Let’s use that potential and move humanity forward.
Intel Open Source Hardware Advisory Panel
I’ve been participating in the Intel Open Source Hardware Advisory Panel this year.
… Intel hosted a series of conversations with the company’s Open Source Hardware Advisory Panel – a group of key enablers in the global open source hardware ecosystem – about licensing, best practices, sustaining development communities, business models, path to product, Shenzhen, and the evolving relationship between the global maker movement and chip manufacturers.
We’ve had some interesting conversations and Intel has been publishing video from our meetings. At the session titled Open Source Hardware Communities, Case Studies, and Guidelines, I talked about the EggBot and its communities of users; Adrian Bowyer talked about the RepRap community; André Knoerig about Fritzing; and David Scheltema about Make and Maker Faire. I enjoy seeing these issues being grappled with, and hope that our conversations will help others as they think about these topics. Videos from the sessions can be found on the panel page at Intel.
STEAM Fest 2015
I took a heap of pictures at the 2nd annual Silicon Valley STEAM Festival at the Reid Hillview Airport in San Jose today. This event brings out an eclectic mix of hobbyists, scientists, and enthusiasts showing off what they do. Below are a few of my favorite moments.
The local RC aircraft enthusiasts not only displayed their aircraft, but also put on an airshow. They also fly at Baylands Park, and encouraged coming to see them on Sundays.
Vintage aircraft flew in to be displayed.
Local science institutions brought their mobile displays, including leopard sharks from the Marine Science Institute.
Robotics teams, (including our very own Firebots) were demonstrating their robots in the midst of cars on display. You can find more robots, aircraft, automobiles and sharks in my album here.
GeekMom reviews Build-It-Yourself Science Laboratory
Sam over at GeekMom just posted a thoughtful and kind review, Bringing Science Home Again: ‘The Annotated Build-It-Yourself Science Laboratory’.
This is exactly what was needed. So much of home-based experimentation right now is focused on technology and making. While there is nothing wrong with that, traditional sciences are just as important. Labs are important. The Annotated Build-It-Yourself Science Laboratory brings the magic of science home again.
Lemon Plum Jam
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.

A visit from the LEGOJeep
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!
