Just a little note to say that our Evil Mad Scientist shop is now (“finally?”) accepting payments in Bitcoin. Our Bitcoin payments are processed through BitPay, one of the largest and most trusted processors for Bitcoin-based online payments.
I’ve probably said it a million times, but I don’t think I’ve told you guys. You’re amazing. When it’s time for a new project I jump over to EMSL first. I use your projects to demonstrate a lot of STEAM principles at my Makerspace, and proudly wear my EMSL STEAM shirt every Saturday morning when I’m teaching our Makerspace Cadets class. (It’s a fun sciencey/makey/artsy class for kids). Keep up the great work. :)
Thank you for the kind words, and for your dedication to your students!
We’re very pleased to announce some updates on the WaterColorBot project— the watercolor-painting pen plotter that we designed in collaboration with Super-Awesome Sylvia. First and foremost: kits are (finally!) available from stock at our store, now that we’ve finished shipping the rewards from our Kickstarter campaign and our other pre-orders.
We’ve also been working on a host of new applications and accessories that we’ll be writing about in the near future. The first new accessory is the Buddha Board holder pictured above, which indexes a Buddha Board (overly-interactive website link / Amazon.com link), that lets you make temporary paintings with just water. We’ve found the Buddha board not only to be one of the best tools for trying out new things on the ‘bot (without using up paint and paper) but also to be great for live demos of the WaterColorBot, so that you don’t need to provide a fresh sheet of paper for everyone that tries it out. You can find it in our new index of WaterColorBot accessories.
We’re running a Thanksgiving sale in the shop: save 20% or more on selected kits and components, Black Friday through Cyber Monday with free US shipping for all orders over $75.
Despite what you might guess from the name, our Egg-Bot kit is not just for eggs. In fact, it turns out to be a pretty freaking amazing machine for decorating and personalizing your own Christmas ornaments!
Today we’re releasing the “Eggbot Holiday Super Pak” — a set of Eggbot-ready holiday ornament designs to give you a head start. The set includes the designs above and many more. It’s free, available for download here (2.2 MB .zip file), and will be periodically updated as we add more designs.
Read on for some additional tips and tricks for using ornaments in the Eggbot!
Hanukkah comes remarkably early this year, starting on Thanksgiving day, November 28.
Today, just in the nick of time, we are releasing two new LED menorah kits for 2013 that complement our consistently popular Deluxe LED Menorah Soldering Kit.
The first kit, the Deluxe Electronic Breadboard Menorah Kit, is a response to two requests that we frequently receive: (1) for an LED menorah kit that doesn’t require soldering and (2) for a menorah kit with assorted multicolor LEDs— for that assorted-color candle look. (Nailed it!)
The kit includes a 6″ transparent breadboard, 10 mm LEDs in red, orange, yellow, green, blue and warm white, a control button, battery holder, and a pre-programmed microcontroller.
While the electronic components— the microcontroller, resistors, control switch, and LEDs —are essentially the same as in the Deluxe LED Menorah Kit, we’ve had to make quite a few changes to the layout and firmware to redesign the circuit to lay out so neatly on a breadboard. Additionally, as the perceived brightness of different LED colors can vary quite a bit, we’ve included a specific set of per-color resistors to even out the overall brightness levels.
The Deluxe Electronic Breadboard Menorah Kit is in stock now, and ready to make happy campers on some night(s) of Hanukkah this year.
For the second new kit, the multicolor Special Edition Deluxe LED Menorah Kit, we’ve brought the assorted multicolor LEDs back to our original Deluxe LED Menorah Soldering Kit. Because, why should breadboarders have all the fun?
And it even looks good with the lights off! The new Special Edition LED Menorah Kit is in stock and shipping now.
We’re pleased to announce our newest kit, the “Three Fives” Kit, a kit to build your own 555 timer circuit out of discrete components. Here’s a way to re-create one of the most classic, popular, and all-around useful chips of all time.
The kit is a faithful and functional transistor-scale replica of the classic NE555 timer integrated circuit, one of the most classic, popular, and all-around useful chips of all time. The kit was designed and developed as a collaboration with Eric Schlaepfer, based on a previous version (pictured here), and adapted from the equivalent schematic in the original datasheets for the device. There have been a few other examples of circuits like these (such as the one that we featured in our article about the 555 contest), but we really like how this one has come together.
The kit is designed to resemble an (overgrown) integrated circuit, based around an extra-thick matte-finish printed circuit board. The stand— which gives the circuit board eight legs in the shape of DIP-packaged integrated circuit pins —is made from machined and formed semi-rigid PVC foam.
To actually hook up to the giant 555, there are the usual solder connection points, but there are also thumbscrew terminal posts that you can use with bare wires, solder lugs, or alligator clips.
One of the really cool things about having a
unintegrated disintegrated discrete circuit like this is that you can actually hook up probes and monitor what happens at different places inside the circuit.
So that’s our new “Three Fives” Kit (shown above with an original NE555 for scale). It’s not quite as big as our 555 footstool, nor as tasty as our edible version, but it’s a great little circuit, and it’s got legs.
If you’re in the San Francisco Bay Area next Monday, we hope you’ll join us for an open house:

Today we’re thrilled to be launching our newest kit: the WaterColorBot.
The WaterColorBot is a brand-new project from Evil Mad Scientist Laboratories and Super Awesome Sylvia — a friendly art robot that moves a paint brush to paint your digital artwork onto paper, using a set of watercolor paints.
We’ve previously written about how we got started on this project (in a guest post by Sylvia), and about Sylvia’s visit to the White House Science Fair, where she was able to give President Obama a personal demonstration of the WaterColorBot.
And now, you can get one too! We’re launching the WaterColorBot today on Kickstarter, and we’d like to ask for your support in getting it out there. The WaterColorBot is an enormously powerful tool for helping to get young people interested in technology:
Beyond simple fun, we think that the WaterColorBot has enormous potential for STEM and STEAM education, especially as a way to get young people engaged with hands-on technology and robotics. We are particularly interested finding ways to inspire young women to pursue careers in science and technology. We cannot imagine any better way to do so, than starting with a robot co-designed by a 12 year old girl.
Perhaps more than anything else that we’ve done, we think that the WaterColorBot really can make the world a better place, one (young) Evil Mad Scientist at a time.
