@larryd, You have a truly expansive and complete setup in your "lab". What sort of projects do you make that require such a vast array of equipment? No doubt they're some pretty cool projects.
A few past projects:


Completed (maybe) work station with tool set:





Working on animated infinity mirrors.
Edit:
Based on this.

Now now e Thread title says it all e Larry posts elsewhere on arduino stuff.

You would be lucky. Most pills come in blister packs these days.
I know because a relative has arthritis badly and i have to open his pack of arthritis pills. :o

Edit.

To be fair the pharmacy offers a weekly pill popping service where they are transferred to an easy to open daily sliding compartment thing.

He has no trouble opening a bottle of scotch however so long as it does not have a childproof cap like those bottles of bleach.
However he has a 7 yr old grandson to help him with that.

A gadget to cope with those would be useful (the type you have to squeeze and turn).

Any ideas Larry ?.
Transfer the internals into an easily manageable bottle.

Going to make a few of these infinity mirrors:

Further to post 401.

For components like USB connectors, add a horizontal vise to the assembly.

Last addition are two rare earth magnets in cups, horizontal and vertical.
As mentioned much earlier, binder/bulldog clips are great for holding work.
The 6-32 screw fits in a threaded hole in the 1/2" Teflon base.

We all have a set of tools that are not being contained.
Tools can easily get misplaced, soon we have a set missing that one tool we like the best.
You can keep yourself organized by making your own 'Tool Pouch'.

If you have access to a 'Hand Impulse Heat Sealer Machine' you can design your own roll-up pouch.
These 'Sealer Machines' cost about $40-50 and come with replacement heating parts.

These easily seal: 6mil poly, anti-static bags and other sheet plastics.

They can also seal that aluminumized half bag of potato chips. ;)

4 mil sheet plastic takes about 2 seconds to seal with 1-2 seconds cool down.



Below is a 4 mil ZipLoc bag, writing is removed with IPA.
Set the timer dial setting to ~3-4 (1-1.5 sec).
Use a spacer to get even compartments.
A tongue depressor is used.

We have all accidentally dumped a bottle of fluid on our work surface.
These 'Sticky Pads' are great in preventing this from happening.

Moving the top out on an infinity mirror gives a downward image.

Just got a few Arduino Mega clones from Terry (reasonable price!).
http://www.yourduino.com/sunshop/index.php?l=product_detail&p=387

You may need to install an Arduino (here a Mega), in a box/case or other platform.
The Arduino designers made major mistakes in the placement of the mounting holes.
These were placed too close to headers etc.

You can make this happen if you use 2-56 screws.

You can make the washers as in post #290

You can make acrylic nuts as in post#109

I use a slightly smaller version of the computer motherboard nylon push through's that have a thread on them.
You can get the board off if you want just by squeezing the tab on the push through spacers and they are super cheap.

The variations make mounting things a breeze



It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

Those work quite well if there are no through hole components near by.

I find in a year or two the nylon/plastic they are made of becomes brittle.

I have some of the white self stick cable tie mounts here that are over 20 years old and work great alongside the large collection of even older computer standoffs.

Its not so much about age as quality.

If the white ones are not subject to UV they will last a very long time and if its going to get any UV then the black ones.
Same thing with cable ties and other electrical nylon / plastic hybrid parts.

Not poo pooing your method at all for custom items.
But for standard items then off the shelf every time.

Just try ensure my stuff is HDPE or similar as its almost indestructable
