It’s simpler and, in a way, more powerful than Bourne shell. Perhaps the secret is I wrote it in the simplest useful language I ever found: Plan 9 shell. Perhaps even keep-alive would be easy if it was structured a little differently.
The whole thing with all its structure and CGI support took about a month, but the server test page – the part of it which serves one page of specialist content – was completed and running within about 3 days of me first starting to learn about HTTP! If you don’t do keep-alive, there’s nothing complicated about HTTP at all. It’s not particularly quick, but it has no problem with virtual hosts or dynamic file generation. I have severe fatigue issues and I get confused over nothing, so nearly all my attempts at programming have failed, but 11 years ago I wrote a relatively full-featured HTTP server in a few weeks. I suppose it’s more understandable on a hardware site, but there’s just nothing to serving basic HTTP. The other thing is HTTP making the headlines.

If you think about my background – all that knowledge of how to do this stuff and all the frustration of not being able to use it – you’ll see how offensive it was when hordes of capable, healthy people declared the rubbish that was the Pi 1 to be a miracle! The thing that really bothers me is all the hype. The one really solid thing I’m aware of in the Pi’s favour is that it’s available in so many countries. Parallel printer ports never went away either, being available as USB add-ons, and they’re configurable as a sort of GPIO.
It’s never even been the most open 32-bit board, as far as I know. The Pi counts as one, in a way, but it’s just one of thousands. Microcontrollers became available to hobbyists at the end of the 8-bit era, and never went away.

That included the PC with its ISA bus, and the ISA bus was still around when the Pi was launched. Every 8-bit and most 16-bit computers had expansion ports you could use for home automation or robots or whatever with only a little bit of external logic. First of all, why is the Raspberry Pi specifically in the headlines? If I’d hadn’t had health and other problems, this is the sort of thing I would have been doing with my 8-bit computers when I was a kid. There are a couple of things I don’t understand, and this seems like as good a place as any to ask about them. Just not as bad as people think because of their experiences with random relay selection. High reliability relays are all over old aircraft and missiles but they were selected for their intended service.
One of the reasons relays have a bad rep is because we tend to think of them as all interchangeable. There are also ways to suppress the arc that eats your contacts including putting a magnet nearby to reduce the effect (no kidding). Whereas a softer material, the spark will erode it, but it probably has better contact resistance so you’d use those for non sparking application (e.g., low power or dry switching). Why not use a tough material all the time? Because they tend to oxidize more. For high spark uses, you want a contact material that is tough. Selecting the right relay for an application can really make a difference. Posted in Raspberry Pi Tagged lawn, raspberry pi, sprinkler Post navigation Once you’ve watered your lawn into overgrowing, you’ll want to cut the grass back. Of course, we can’t think about sprinklers without thinking about those poor cats. We think you could do the same basic thing with HTTP Request Shortcuts, on Android, or any of many other similar apps. An iPhone app called Curler creates a good-looking use interface to call the API. But the basic idea is to create an HTTP server using Flask for Python and exposing a basic Web API.

It looks like the software section of the tutorial is a work in progress. That should be a good basis for your own design. However, there is plenty of information about how he placed the zones and why he made the choices he did. Of course, your yard will be different, so some of the design will change if you decide to implement this yourself. But it also has a hydraulic part, so you have to deal with all three domains coming together. It is an interesting project since it has hardware and software components, of course. The goal: build a low-cost lawn watering system. However, it is a big leap to actually use the Pi to control something and a good example can go a long way to helping you develop your own projects. Running an ad blocker or a VPN gateway is simple and doesn’t require any real interfacing. It is easy to take a Raspberry Pi and treat it like a cheap Linux PC or server.
