## Take and Make: Trammel Kit

12-28 Update.  We continue to iterate on the Trammel Project.  Dr. Sereveny’s students at Riverbend Community Math Center have updated the files with a larger hole for the pencil/pen and they are working on an adjustable arm so we can make multiple shapes (of Ellipses). And they sent Links to the Hardware screws and filament: Hardware: https://smile.amazon.com/gp/product/B07XRX2F4Q/ref=ox_sc_act_title_1?smid=A2N32G193BWL7U&psc=1 We use a

## Take and Make: Tabletop Optical Illusions and Perspective Playground

We found an instructable on making chalk art patterns in CorelDraw.  But guess what? — you can use this technique to poster print all kinds of fun 3d designs.  The instructable is here.   Its pretty cool! We sent a logo perspective box, aReuleux car and some conic section models to the NWMath Conference. PDFs can be printed in various sizes.  “Chalk”

## Mathemagician Sunday Funday – Neill-Cochran House Museum

We built mathematician kits! We explored the magic area puzzle, cut and assembled linkages, taped impossible cylinders, made cipher nametags, proved that 64=65, a geometric dissection with hinged pieces (circle – square – heart) and more.  Read about the whole kit here.  There are links to printable versions, and notes about each project. Thanks to Quan Nguyen, Mason Chng and

## Cinco de Mayo! We had a blast!

What a nice event at the George Morales Dove Springs Recreation Center!

Many thanks to Austin Public Library and our

## Take and Make: Magician’s Rods
