I replaced a doorknob yesterday.

When the condominium was purchased which I have been living in since 2007, the doorknob to the storage room was partially defective. Later on, it could happen that this doorknob would simply fall off the door.

This was unaesthetic, as well as presenting a possible danger, of my not being able to enter the storage room, under the wrong circumstances.

I had made numerous attempts to repair the old doorknob, but doing so would have required spare parts, which the previous owners did not leave me.

I got the impression that this one doorknob had been installed by the previous owners, but that they had already botched the job, and that they had only left me with doorknob components which were unusable.

And so while already having made the trip to the hardware store yesterday, I decided that I could also pick up a new doorknob.

I also installed the new doorknob to the door yesterday without much ado. The only remaining problem is in the fact that the new doorknob isn’t centered exactly as the old one was. This can be common, as long as the hole into which the doorknob has been installed never shows. But it also means that in order to look professional, the door surface around the doorknob needs to have its paint-job retouched.

The new doorknob will never become loose again.

I have not retouched this paint yet.

My new battery required I do an Epoxy Job yesterday.

Yesterday I wrote, that I had received a new battery for my age-old laptop named ‘Venus’. Installing this was more than just a job of inserting it, and thankfully, the battery did fit.

Back in the year 2010 I was experiencing overheating issues with this laptop, in response to which I had attached plastic doorstops to its bottom, to act as spacers, and to allow air to flow. It sits roughly 3/4 inch above its cooling tray. The type of doorstop I used was a simple, convex type, which was also the only kind I could have used.

This required in 2010 that I attach some of these self-adhesive doorstops directly to compartment doors on the underside of the laptop, which can be opened or removed. And yes, one doorstop needed to be attached to the removable battery.

Hence, with the arrival of a new battery, I was 1 spacer short, from having a platform that was stable standing on 4 spacers.

So next, I looked at a local hardware store to see whether I could find an exact replacement for the doorstop which should go on the new battery. But that kind of primitive doorstop was not for sale. The hardware store was willing to sell me fancier ones, which could actually be used as doorstops, because the newer ones all have refinements that will make them look decent in the home. But the new doorstops also require the use of screws to be fastened, while the one I was looking to replace had been self-adhesive.

And so what I finally did – because I wanted to get on with setting up my laptop and not go on a shopping adventure – was just to buy some epoxy glue, which is being sold these days in pairs of syringes which are easy to use. We cut off the tips of the syringes, deal with any air bubbles, and then lay down two lines, of epoxy resin and hardener. Then we mix the two viscous fluids thoroughly with some disposable plastic tool. And we obtain a quick-setting resin, ready to adhere.

I had been able to pry the doorstop off the old battery without damaging it, which meant that I was ready yesterday to glue it onto the new battery.

The only disastrous fantasy I now have, is that the type of plastic used to make the doorstop, may not form a long-term bond with epoxy. If that should be the case, the newly-glued spacer can simply fall off my laptop one day, when I’m handling it, and when I’m least likely able to deal with it.

It is already written, that epoxy glue is not compatible with polyethylene or polypropylene. I’m sure that the laptop’s surfaces are neither, but am not sure about the (cheap) doorstops’ surfaces.

For now, the one homemade spacer has continued to adhere since yesterday, and not only the three, which are attached with the adhesive backing they were manufactured with.

In any case, in addition to the epoxy, I also bought some generic superglue, in case I might need it. But realistically, if the epoxy does not hold, and I’m forced to try repeating the exercise with superglue, my long-term chances of success have already become Nil.

I received a new battery for my Acer Aspire today.

One fact which I did write about, was that I own an old ‘Acer Aspire 5020′, in addition to my other computers, but that the network name of the Acer laptop was ‘Venus’, when it is running in Linux mode.

This laptop was manufactured in 2005, and needed a new battery.

What’s remarkable about this, is the fact that the Lithium Ion battery it came with in 2005, may only have held a fraction of the charge it was supposed to, but still held a charge in 2016. This is because unlike today, in 2005, Acer produced high-quality products. But given the times, I would not buy an Acer today.

The old battery was holding a 1-hour charge in theory, although it would never actually reach that, because my settings forbade the charge from going below 25%.

Now that I received the new battery, I expect that it will hold a 2-hour charge again, and that I can safely set the laptop’s critical level to 15% again. But I do not expect, that the new, gray-market battery, will also last another 10 years.

I needed to restrict my Vacuuming Robot today.

One fact which I had written about earlier, was that I have a “Neato XV Signature” vacuuming robot.

Neato XV _1

This robot has frequently gotten lost underneath my bed, presumably because the lower surface of my box is a canvas sheet which hangs below the sensor-line of the robot’s laser, in a way that’s curved almost parallel to the floor. The robot cannot analyze the geometry which this seems to forbid it, and can therefore sometimes end up in an endless loop. Because I want to be able to trust my robot with vacuuming 100%, when I’m not home, this error required adjustment.

Using great lengths which I have, of the magnetic boundary marker, I now also zoned off the rectangular region which is the entire underside of my bed. The robot no longer goes there.
