Revisiting the Alto Professional Presenter

Late last year I detailed my quest to find a small public address system for use by our local civic association. I settled upon the Alto Professional Presenter, which is a portable, battery operated PA in the form of a podium. What follows are some notes about how I’ve used it over the past nine months, and some recent tweaks to the setup that have made me irrationally happy.

While I was initially quite enthusiastic about the product, that proved to be substantially unwarranted. Out-of-the-box it’s actually quite terrible. It’s a nice idea, poorly executed.

The major problem is the included gooseneck microphone. You can’t turn the device up loud enough to be useful without generating feedback. As a practical matter, the position of the microphone is fixed relative to the front-facing speakers. Also, I suspect the microphone suffered from being physically connected to the podium. The physical connection increases the likelihood of feedback, as vibration was passed directly to the gooseneck.

On “Solar Generators”

Hi. My name is Michael and I am a pedant. I don’t mean to be, but it really can’t be helped.

I come to this admission when faced with an online discussion of “Solar Generators.” I believe this term arises from really poor use of language.

There really is no such thing as a “solar generator.” Except perhaps the sort of installation found in Nevada’s Ivanpah Dry Lake.

Let me break this down a bit:

Generators

Burn some fuel to create motion, which in turn creates electrical energy.

Open Live Writer: Goldilocks and the Three Bears

This blog has been in existence for some 19 years. For most of that time the various posts have been written in Open Live Writer. OLW is the open source successor to Windows Live Writer, which was a free Microsoft app. Last time I wrote about it was ten years ago when the Dot Net Foundation assumed the project and cast it into open source. As in many things, I am anomalous. I still use it routinely.

I was reminded of how anomalous I am when I recently had a problem posting to my site. This has happened periodically. Lightningbase, my long-time host, has various protections in place to keep people from doing nefarious things with the XML-RPC process that OLW relies upon to access WordPress. Occasionally, I have to ask them to tweak the host protections to allow me continued access from OLW.

Instrumentation Options for a Portable Generator

In various online forums, people are routinely asking for help when faced with a generator that’s being overloaded. This may be in the context of a food truck, mobile pet salon or delivering whole house backup power.

It’s believed that management guru Peter Drucker once said, “You cannot manage what you cannot measure.” I have been making a lot of use of that quote when offering answers to such questions. If you are placing a significant load on the generator, you need to monitor the load to know when you are nearing overload. Allowing it to overload is disruptive, time consuming and potentially dangerous. Without hard data to inform your decisions, you’re only guessing about how to address the problem.

Option #1: Built-in Load Monitoring

If you don’t yet have a generator, you might well consider instrumentation in making that choice. For example, my Harbor Freight Predator 9500 was one of the first of a new crop of high-power inverter models that became available in 2021. It does not have any built-in instrumentation. So, it was incumbent upon me to provide such capability externally.

In contrast, a bit over a year or two later a neighbor bought a Pulsar PGD95BISCO from Home Depot. This Pulsar if effectively a cousin to my Predator. They’re both made in China by Chongqing DK power machinery Co.,LTD. The Pulsar model was introduced later in February of 2023. To be competitive it has a few more features that the Predator. One of the nicer features is a built-in load meter.

The built-in LCD shows the output voltage, frequency and aggregate load on the generator in real-time. This is very handy. I wish my Predator had this feature.

Oh, bother. Where art thou? Base Power

I first wrote about Base Power back in May 2024. Inspired by Doug Lewin’s Energy Capital podcast, I signed up for the companies mailing list, in the hope of learning when they Austin-based company would be offering service in Houston. In fact, I’ve signed up twice!

We’ve received literally nothing from the company. Putting our address into a page on their web site they report “Great news! Base is coming to Houston soon! We’ll be installing in your area later this year.”

Back in February of 2019 we bought a new furnace…in a hurry. Our furnace went out during a cold snap. The old furnace died at about 5pm. I called my then favorite HVAC contractor. He hustled over to investigate, delivering a prognosis by 7pm. He rightly noted that the 25 year old Kenmore furnace had given its last gasp. It could be repaired, but getting the parts would take days. The wise choice was to replace it outright.

I was thinking ahead to a new AC unit, so I wanted a top-end American Standard natural gas furnace with a variable speed blower. That would allow us to install a high-efficiency, variable speed air conditioner in the future.

It happened that he had exactly what we wanted on stock. It was sitting in a warehouse, ready to be installed in his own home, which was a new build. His crew installed that furnace in our house the very next morning. By 10am the heat was back on. It all happened so fast. While I doubt we got a bargain, he certainly earned our gratitude.
