Awe, it’s so… OMG!!! #evilmadscientist #battleforthebones
When we saw NanoBeam on Kickstarter, we had a hard time comprehending just how small it is. So we asked Hyrum if he could send us some pictures for a better sense of scale, and he obliged. Yes, it fits in a tic-tac box. After seeing just how teeny-tiny a 5 mm beam is (one quarter the cross sectional area of Maker Beam and one ninth of Open Beam), our next question was “What the heck?” So we asked what made him think of making such a tiny beam.
I just wanted some tiny beams to build a small robot. I looked all over the place but couldn’t find what I wanted. After some research, and talking to some extruding companies, I designed a beam that was so small it challenged all the rules of this manufacturing science. I made a few on my cnc mill before I commissioned the die, to be sure it was what I wanted.
How did you find a factory to work with?
I combed the web and talked to a lot of companies. I finally found one that focused on small extrusions. I saw the amazingly small and precise work they were doing for companies like Boeing and 3M and I knew I found the company I needed.
What kind of fasteners do you use for something this small?
I used the largest screw I could but they are still small. The size is M1.2; you will find these in some pairs of glasses. I’ve got 3 designs for the nuts, I am waiting on manufacturing samples for the last one before I decide for sure which I will use.
We asked what he thought NanoBeam would be useful for.
Immediately, I see this making a splash with small robots, quad copters and electronic enclosures. I also see it being great for diy wearables, scale models and crafts. I recently got feedback from a guy that wanted to use them as a frame, conductor and heat sink for an LED array. I can’t wait to see something like that. I’m going to get some stock without the black coating for this application.
We’re also very interested to see what people do with such a tiny extrusion! Thanks to Hyrum for answering our questions. You can find out more, and check out his designs (Open Source Hardware definition compliant) at the NanoBeam website and the Kickstarter campaign page.

We’ve talked previously about making simple LED pumpkins with candle flicker LEDs. Lately we’ve been playing with making better looking flames by using multiple independent flickering LEDs with different colors and lens styles. It makes a spectacular difference: it goes from something that looks like, well, a flickering LED to something that really looks like there might be a flame in there.
The end result is pretty neat: A compact battery powered “flameless flame” that looks great in a pumpkin, luminaria, or as a stage prop. The interplay of the different LED types and colors gives an ever-changing and shifting flame display.
- Battery Holder (2×AA with switch)
- 6 × candle flicker LEDs (2 red diffused, 2 yellow diffused, and 2 yellow clear lens)
- 6 × 68 ohm resistor
- 2 × wire jumper
- White paper bag (optional)
- 2 × AA Batteries (not optional)
- Wire clippers, cutting pliers, or “beater” scissors (optional)
Hook up the battery holder to the breadboard several rows apart to give enough room to install the resistors and LEDs. Optional: peel off the backing on breadboard and adhere it to the battery holder. Connect each LED with its own 68 ohm resistor. (Use the “in parallel” method from this article.) The extra jumpers are included to help bridge across the center gap in the breadboard.
Trimming the resistor leads will keep the breadboard tidy, and help prevent short circuits. Trimming the LED leads to varying heights will help distribute the light in different ways.
The white paper bag included with the kit can be used for creating a traditional luminaria or for making a ghostly halloween decoration.
For Lady Ada Lovelace Day, we would like to celebrate some of the women working in science, technology, engineering, art and mathematics that we got to meet and spend time with at Maker Faire New York this year.
Our friend AnnMarie Thomas had just released her book Making Makers, and was speaking several times during the faire, including hosting the Making Makers panel I participated in, as well as assisting her daughters, Sage and Grace, in presenting a Squishy Circuits workshop.
Patricia Miranda of Alchemical Tech was there again this year teaching dye-making. I reluctantly declined her offer to get my hands dirty.
Jenine Bressner, who has been sharing her glassworking and laser textile projects at Maker Faire for years, was there as an attendee, finally getting a well-deserved chance to see the faire.
Emily Fischer of Haptic Lab was displaying her beautiful astronomical quilts.
Peggy Monahan of NYSci was helping run a costume design workshop with low cost, easy to use materials like plastic tablecloths, butcher paper and snow-cone cups. Many people bedecked with dinosaur spikes and other fanciful accessories could be seen roaming the faire.
Representing Othermachine and demonstrating the Othermill was their project and support engineer, our friend Simone Davalos.
Rachel Meyer, Selena Ahmed, and Ashley Duval of Shoots & Roots Bitters are three scientists who care about culturally important plants, and bring their stories to people through their uniquely blended bitters.
Toward the end of the faire, we ran into Limor Fried of Adafruit. It was great to catch up with her and hear about the great strides her electronics business has been making.
There were many more women there showing amazing projects. If I left out someone you want to celebrate, please feel free to share about them in the comments.
Halloween, always one of our favorite holidays, is fast approaching again. We’ve updated our Halloween Projects Archive as we do every year to ensure that all of our Halloween projects are gathered together in one convenient location. We’ll continue to add projects as we post them. If one of our projects inspires you to make something, we’d love to hear about it!
We’re excited to be bringing the EggBot back to the East Bay Mini Maker Faire on Sunday, October 19. The schedule of presentations and performances covers everything from “The Importance of Junk” to minestrone making. The list of makers attending covers the gamut as well. Evil Mad Scientist readers get a 15% discount on advance tickets using the code MAKERFRIEND.
We love RoboGames. The range of competitions is so broad, there is opportunity for participation from roboticists of all backgrounds. We received a silver medal in the bartending division of the art robots category in 2011 with Drink Making Unit 2.0. In 2013, we helped Super Awesome Sylvia create the WaterColorBot, which won silver in the painting robots category. We helped to produce the medals for the winners in 2009 and 2013. But more important than our personal successes and participation, we have been privileged to see the excitement that comes from the entrants, whether they are competing in soccer, fire-fighting, sumo, or crowd-pleasing combat.
RoboGames is also planning production of a video series around the event, to bring it to those who can’t be there in person, and so that you can enjoy it whenever you need a good dose of robots.
The upcoming lunar eclipse on Wednesday morning will offer a rare possibility for some viewers: a selenelion. Some locations (east of the Mississipi) may be able to see the setting eclipsed moon and the rising sun at the same time. But wait, it’s an eclipse, so that means that the sun and moon are on opposite sides of the earth, right? Right. So you shouldn’t be able to see them at the same time, right? Wrong. The earth’s atmosphere refracts the light from both, letting you see the sunrise a little early, and the moonset for a little longer. A guide to what part of the eclipse will be in progress at sunrise at various locations is available at space.com. You might just want to get up before sunrise for this one!
