Bike Phone Mount - Repurposed 23-25C Tire Tube


I combined ideas from handlebar phone mounts and bag phone mounts. The key to this application working is the nature of rubber and that it has wonderful self adhering properties. When the phone is wrapped at the corners and over bottom of the top tube you can stuff the excess tubing after the wrap and that will adhere to the tubing underneath, given that there is sufficient pressure to hold it all together.

Sufficient pressure is attained if you wrap the phone while applying and maintaining a bit of tension throughout the wrapping procedure. Because the brake cable was constricted and therefore brakes were of limited operability, I had to house the exposed brake cable with a plastic straw, which I cut length wise down the middle and covered in bike handlebar tape. There was still some constriction to the brake cable but they were quite operable.

This phone mount system was necessary because it seems most top tube bag mounts do not fit larger phones such as my LG Stylo 5. Additionally, top tube bag mounts interfere with the shifting mechanism of my bike (Kent 700 RoadTech). For a waterproof system, put the phone in a Ziploc bag before wrapping with the tubing. Touch screen is operable beneath Ziploc bag and beneath the tubing.

Note: care must be taken to make sure that power and volume buttons are not depressed by the tubing wrap. Also, access to the headphone jack and the USB-C port require a bit of pushing the tubing around. On my phone, both ports are on bottom of the phone; the headphone jack would be on the left of the tubing, and the USB-C on right.

See below for pictures of the bike bag phone mount systems that are available on the market.




Phone Mount Wrap Procedure:

I cut a bike tube to 43 inches. Extend a phone length of tube toward the handlebars.


Lay the phone over the extended length of tube and wrap the top left corner of the phone, bringing the tube under the bike top tube and around to the bottom right corner of the phone.

Wrap the bottom right corner bringing the bike tubing around the bottom of the top tube once again, and then over the bottom left corner of the phone.

From the bottom left phone corner, bring the bike tube once again under the top tube and around the top right corner of the tube. Bring the tubing once more around the top left corner from underneath, and you'll have a piece of tubing remaining. Take this bit of tube, fold it in half and stuff it underneath the phone. You'll find that the whole mount system is rather stable.

Learning to be a TN Amateur Naturalist

#1 Google hit for "TN amateur naturalist" http://tnnaturalist.org/ Memphis Chapter, has good contacts from the biggest Naturalist institutions in Memphis. http://tnnaturalist.org/4-Memphis.html Promo of program from TN State Parks https://tnstateparks.com/get-involved/tennessee-naturalist-program The books I got from Memphis Library (Ben Hooks), the 500 section (574) on the 3rd floor. It will be good to reach out to some of the Memphis Chapter folks and see what I get back. Have to think through what "reaching out" means.

Plastic Origami Field Use Microtome

Plastic origami (plastic folder source) worked well to make specimen holder. 2 widths possible by either folding down on bottom to furthest stop or by placing bottom together in slit cut. Slide holder is filled with water and specimen is hand advanced with the slightest of nudges over the length of the specimen holder. Cuts are made on the other side of the glass slide, which holds the specimen holder in place and also acts to create a smooth cutting surface for better quality cut (using standard razor blade). The glass slide has a semi-ovular cut from the bottom using a steel wheel glass cutter (see video). This cut allows the specimen to advance beyond the glass so that the specimen can be cut. Cross sectional cuts of stem are picked up with needle nose forceps and placed on a slide. Extra water was absorbed with Kim wipes separating slides. Clear tape is used as cover slip to secure specimen to slide and then specimen are examined using Carson handheld microscope. ...
