I would just assume purchase one of these. However, I can't find one quite like the clip provided by easySensors CP2102 with Pogo clip for 2.54 pitch FTDI headers located https://www.tindie.com/products/easysensors/cp2102-with-pogo-clip-for-254-pitch-ftdi-headers/ . They have been sold out for quite some time.

After you print it out, you'll need to drill out the holes for the pogo pins. Additionally, I stretched out the spring, shown on the pictures, to fit the clip. I've included the dimensions of the smaller spring that I had on-hand and shared a link of a larger spring that should work better on the parts list below that should work better. Finally, the rubber band will help with tension.

Here's the parts list.

• 6 - P75-E2 Spring Test Probe Pogo Pin 1.3 mm Conical Head 1.0mm (I recommend having spares)
• 9mm Outer Diameter 1.2mm Wire Dia 30mm Long Compression Spring (I'm guessing here)
• M5 machine screw and nut (a least 25mm in length)
• Female Header 1x40 2.54mm (trimmed down to solder onto ends of the pogo pins)
• hot glue to hold the header/pogo pins in place

Backstory:

Starting with the Instructables post by Eric Tsai (https://twitter.com/Eric_1100). I found inspiration with DIY home automation. Computourist (https://github.com/computourist/RFM69-MQTT-client) cleaned up the programming and added the ability to transmit to end nodes. Then I found a great forum that has simplified the build and offers a great community http://homeautomation.proboards.com/post/2053/thread

This is my attempt to contribute back to the http://homeautomation.proboards.com/ community
