Step 1: Materials & Tools
11.5oz coffee can
Usb Wifi Adapter w/ or w/o usb cradle
Razor knife to cut can with. I'm not blessed with a dremel. :(
Needle nose pliers and/or wire cutters
Duct tape because it has a light and a dark side
Step 2: First, Some Math.
hell yea hazelnut bro
Inside Length 5 5/16 in.
Outside Length 5 7/16 in. (not used)
Inside Diameter 3 15/16 in.
Outside Diameter 4 in. (not used)
And we know:
1 inch = 25.4 mm
1/16 in = 0.0625 (decimal)
So, to use the calculator I found here: http://www.saunalahti.fi/elepal/antenna2calc.php
I needed to do some simple English -> Metric conversion.
Inside Length 5.3125 in x 25.4 = 134.9375 mm ~ 135.00 mm
Inside Diameter 3.9375 in x 25.4 = 100.0125 mm ~ 100.00 mm
The calculator gave me these figures for my project.
Target distance from bottom = 46 mm ~1.811 in ~1 13/16 in
Target depth of insertion = 31 mm ~1.220 in ~1 1/4 in
Target length of can = 138 mm my can is 135 mm. Difference negligible
Hey, I know it was for a real antenna with a Type N connector, but that just simply wasn't available to me. The principle is still the same nonetheless.
My Belkin Wireless 802.11b USB adapter/dongle: 3/8 x 1 5/8 in
Step 3: Marking and Cutting
Don't make the mistake I did and try to cut through the 'seam' of the can.
Don't ask me why I left the label on the can, either. You can see at the end that I just rolled the hole open on the right side to the necessary size. I flattened the rolled points by laying the the can on the workspace and tapping the inside of the can.
Step 4: Quick Test
Step 5: Putting It All Together
Attach the hanger and adapter with copious amounts of duct tape. Hey, it binds the universe together you know.
