Reduce Hand Stress - Left-Click With Your Foot!
article #1252, updated 31 days ago

Admittedly this is a bit of a contraption, but it has worked wonderfully. I type a whole lot at work, and over time tried a large number of ways to get rid of hand and arm stresses. Eventually, having got my positioning right, I found that an enormous remaining stress was my mouse and most especially the left-click, which we all do a very large number of times per day. So I bought this:

from here:

www.ergoguys.com/pctrac-tracball-w-superiorx-button-control-softwar.html

which is a nice big trackball for multiple fingers or palm (I found the small ones worse, not better, than my mice), and more importantly, those three jacks. It’s one jack per mouse-button. Originally I had thought to bring left and right buttons to foot, but I ended up doing just the left, which has done me just fine and dandy. I initially bought two of these:

www.clearlysuperiortech.com/external-buttons

similarly:

www.ergoguys.com/sbuexsw.html

because they were not expensive; I destroyed the first one (with my foot, they’re not exactly designed for stomping) in a few months, which gave me enough time to figure out what to do. Soon I received a marvelous inspiration, and looked into a “ribbon switch” or “tape switch”. These are industrial components used on conveyor belts to detect items, and safety applications where one wants to stomp on something to get it to stop. So I bought one of these:

www.tapeswitch.com/store/proddetail.php?prod=1100

in the one-foot length to save at least a bit of money, with the aluminum channel for mounting (I think this is needed), mounted it on a 48”×6”×3/4” piece of wood, had my friendly neighborhood electronic musical instrument shop solder me a 1/4” mono phone plug on its wire, ran a long wire from that plug to the 1/8” jack on the trackball…and it works!!!

There is a bit of technique I have had to learn for it to work easily, a kind of bounce of my heel to mimic a rapid left-click; and I do sit now with one shoe off, tread does not help; but I have zero pain in my hands after work these days, which is quite the joy.

Admittedly the trackball and ribbon switch are not inexpensive. On the other hand this trackball looks and feels, inside and out, that it will work for decades, and the ribbon switch is an industrial component, so unless I mounted it badly it will do for a nice long time. The only thing I might have done differently is to get a longer ribbon switch, probably two feet long, though that is luxury, not necessity!

Improve engine lubrication
article #1107, updated 183 days ago

At your own risk!!! For the brave and the risk-tolerant only, put five grams per liter of Hexagonal Boron Nitride, also called HBN:

https://www.bulletcoatings.com/product/hex-boron-nitride-hbn-powder/

in your engine oil. Smooth power, like wow :-) The stuff is actually very non-toxic, it is the primary ingredient in many women’s cosmetics. An extremely fine powder, and extremely slippery. Do NOT put it in any transmission…

Laptops for Missionaries
article #1194, updated 197 days ago

Lately I (Jonathan) have been taking old laptops no longer worthwhile for Microsoft Windows, and setting them up for some friends of mine who travel to the Solomon Islands and Papua New Guinea and other places. They go bearing gifts, digging freshwater wells for people suffering the lack quite a lot; and they go bearing the joy of the Lord.

So far Linux Lite has been the best of several distros for the purpose. It is extremely reliable and hardware agnostic, installs quite rapidly, and has the available breadth of Ubuntu, including helpful language support, while being a very nicely lightweight OS.

Here is my install outline at this writing.

Upgrade (make visible) Snapshots in a ReadyNAS, and Delete Them
article #1147, updated 318 days ago

When ReadyNAS firmware is upgraded, snapshots can become invisible, losing much space. To fix that:

  1. Turn on SSH, in System / Settings / Services.
  2. Using putty, SSH to root@nas , where “nas” is the IP of the NAS, using the admin password.
  3. Do this:
touch /.force_snapshots_upgrade
systemctl restart readynasd
  1. The GUI will report upgrade in progress. Wait for it.
  2. We have now fixed it so we can do things to the snapshots. Let’s make them visible in the filesystem. Browse to Shares, click on the share name (often Backup), click the gear icon on the right, and check Allow Snapshot Access, Apply and OK.
  3. We can now see them at \\NAS\Backup\snapshots. If we create a blank directory on the Windows server’s hard drive, say C:\B, and do the following, we will wipe all of the snapshots on that share and begin recovery of all of the space:
    ROBOCOPY C:\B \\NAS\Backup\snapshots /MIR /R:1 /W:1
    Full recovery of the space actually takes a bit more, there are automatic elements which initiate after the above is done, and also after the next step is done.
  4. Then we run a Balance operation which Netgear recommends. Browse to System, then Volumes, and then click the Gear icon inside the NAS object, and choose Balance. This will take a while, and more space will be recovered. A weekly Scrub and Balance are both recommended. Scrub actually takes longer.

Bicycle Derailleur Adjustments
article #1130, updated 365 days ago

If you bicycle much using the most common shifting systems, you’ll need these. Thus far I am finding the instructions on Liv’s Cycling to be best for the rear, and wikihow or madegood.org for the front. The most important thing yet learned: instructions often get the “H” and the “L” limit screws reversed for whichever bicycle you’re on. Got to check it for each derailleur, by seeing the slight movement per half-turn of each screw. General thoughts:

  1. Mounting position has to be right. This is not very confusing in the various web resources studied.
  2. Each derailleur, front and rear, has an H screw and an L screw. On each, one screw sets the max deflection towards the frame, the other sets the max deflection away from the frame. These are called limit screws.
  3. Cable tension can simulate one of the limit screws. Use the tension caps on the gear control, or (when they are there) the caps on the derailleurs themselves, to relieve tension, to verify that you are seeing reality of limit screws, not the simulation of the cable tension :-) Which screw tension simulates, also varies by make and model and type of derailleur.

BBQ sauce with no added sugar
article #1116, updated 413 days ago

This is “Cornell Chicken Barbecue Sauce”, created in 1950 by Robert C. Baker in order to encourage certain kinds of agriculture, especially that of chicken. The sauce remains extremely popular in certain places. And it has no added sugar, unlike every BBQ sauce this writer has ever seen in many supermarkets.

1 cup cooking oil
1 pint cider vinegar
3 tablespoons salt
1 tablespoon poultry seasoning
1/2 teaspoon pepper
1 egg

Beat the egg, then add the oil and beat again. Add other ingredients and stir. The recipe can be varied to suit individual tastes. Leftover sauce can be stored in a glass jar in a refrigerator for several weeks.

Very simple machines this time: suspenders
article #912, updated 1056 days ago

This post is not for all or even most, certainly :-) But if you want suspenders which snap onto belt loops, rather than the usual variations on alligator clips or buttons, they really exist and work very well, from here:
