Antenna Winding Peg
Description
These pegs were developed for [Eli Bridge's lab](http://thebridgelab.oucreate.com/) at the university of Oklahoma during a postdoctoral appointment. This was originally designed to create custom antennas for RFID readers developed in the lab. Any number of these pegs can be printed and used as boundary guides for loop antennas. The size of the loop (and thus the optimal wavelength) is determined by how you arrange the pegs on a plate. If you are new to this, you can use a simple calculator for loop antenna windings such as (this site)[https://on6wg.pagesperso-orange.fr/Loop%20Antennas%20and%20Calculator.htm]. This design is capable of creating circular, triangular, rectangular, and lots of other shapes of antennas. Additional information can be found [on my website](wesleythoneycutt.com), but it might be a few weeks until this post comes up in the queue. **This is a Customizer Thing, do not manually scale in your slicer. Native OpenSCAD file is provided to play with. Example .stl files are just a demo** **To use:** 1. Calculate your antenna size and number of windings. 2. Customize the print using the Thingiverse customizer or OpenSCAD. -- Adjust the scaling factor to create an appropriate size peg. 3. Print as many as you need. This will vary based on the size of the peg and the shape you intend to make. 4. Drill some holes in a board which matches the calculated dimensions of the antenna and run some bolts through them. 5. Bolt pegs to board. This is designed for #6-32 or M4 (specify imperial or metric in the customizer! for a perfect fit. I used wing nuts, but you can use whatever you have available. 6. With the "channel" of the pegs facing out, wind your antenna loosely such that the wire slips into the channel. 7. Wrap tape or encapsulate wound antenna. 8. Rotate the pegs counter clockwise to release the wire. A 90 degree rotation will release from the channel. A 180 degree rotation will release from the channel and prevent the antenna from slipping down the slope if you wound it extra loosely. **Printing specs:** Print in place, does not require support. I used ABS so I could acetone smooth the result, but this is not required. Have fun! Please cite your source if you use or remix this design. This project didn't warrant a paper and a DOI, so a shoutout is fine if you use it in academic work.
