I was taught to plug the entrance up with grass clippings so they have to work a bit to get out. If they're not out in 3 days remove the plug for them. Seems to work.

It looks like a funnel. For filling 55 gallon drums possibly.

I tried the Japanese red variety a couple of years. Some came up & had a few flowers but never matured properly.

Buckwheat is an excellent choice. It reseeds itself easily & can give several crops per season in long growing season areas. It also makes great honey which is certainly a plus.

Other good ones for bees are borage & comfrey.

Those are 1 micrometer spheres.

Look at that strange character again. They are latex spheres used to check astigmatism in electron microscopes.

Anybody care to guess the diameter of these tiny latex spheres?

It's worth pointing out that some of those pix show some defects which is probably why I took them in the first place. The whiskers on the set of leads on the bonding pads is not normal. The splattering on the other is also a defect. The middle picture appears to be a defect with the etch process. "Chips" are made with many layers, each having an etch process done to it. Put some stuff on then take some of it off. Rinse & repeat.

Sort of. Maybe. Possibly. Those are bonding pads that connect an integrated circuit to the outside world before the device is encapsulated. I have no notes about exactly what specific devices are shown. Could be almost any integrated circuit.

Here are some more examples.
