For Hanukkah this year, Ol Rappaport modified one of our Deluxe LED Menorah kits into a custom fluorescent acrylic body, substituted UV LEDs and used a USB power supply.
We’ve just added two new magnetic easels for AxiDraw to our lineup of AxiDraw accessories. They are sturdy work-holding tools that provide an alternative method of positioning paper or other workpieces for use with the AxiDraw. A heavy-duty alternative to the regular clip easel, they can be used with binder clips or the included positioning rulers and magnets.

We’ve just added two new accessories for the AxiDraw V3.
The first of them, shown above, is the XL Pen Clip — something that we’ve had a number of requests for. The pen holder on the AxiDraw normally fits pens and other instruments up to 5/8″ (16 mm) in diameter. However, this new XL pen clip can hold instruments up to 1″ (25.4 mm) in diameter.
That is to say, it can hold things like this freaking huge marker:
The second new accessory is a little more subtle: an Italic Pen Adapter that gives the AxiDraw a “right handed” grip on pens.
It’s a little bracket of anodized aluminum, with captured screws and threaded inserts, which rotates the AxiDraw pen clip 45° out from the X-axis of the AxiDraw. This angle can give a slightly more “natural” look to certain types of handwriting-like plotting.
And of course, it’s ideal for use with various types of blunt-tipped pens, including chisel-point felt tip pens as well as pens with stub and italic nibs.
The book, published by No Starch Press, turned out beautifully. It has good pictures, clear drawings, and bright colors.
It brings a few of our classic projects onto the printed page, including LED-lit Sea Urchins, Electric Origami, the Dark Detecting LED, and Edge-lit Cards. Thank you, John, for letting us be a part of this!
