Apply some lessons learned in Sci-Fi literature and you’ll come to the same realization I have: Google is going to unknowingly enslave humanity to an artificial intelligence.
I read a lot of science fiction. Generally, the future of technology can be found in great novels if you read between the lines. One of my favorites in this regard is, of course, [Neal Stephenson] who writes cripplingly long books that are totally worth the read due to his brand of fact-backed forward thinking. Look back on my posts here at Hackaday and you’ll see that I frequently apply concepts from his book The Diamond Age to what we see in emerging technology.
Last year my friend [Nils] suggested I give [William Hertling] a try, specifically his Singularity Series which starts with the novel Avogadro Corp. The fictional company is the world leader in free email and data storage. Sound like someone we know? One of the research projects within the company is an email plugin called ELOPe that will parse all past communications and choose topics and phrases that have the highest probability of eliciting a positive response from the recipient. When funding for the project is threatened, the system is turned on. I’d like to avoid spoilers, but let’s just say this puts the system on a path toward enslaving society.
Google is now boasting “Machine Intelligence for You”. It’s a research project based around Gmail which is called Inbox. Inbox has been around for a while but the newly announced feature is an algorithm that reads the email for you and suggests a set of responses. Compared to Avogadro Corp this is only missing two things: the ability to respond automatically, and the directive to protect itself at all costs.
One of the things I liked best about [William Hertling’s] take on an Artificial Intelligence was the low-key nature of the entity. It wasn’t a super-high-level thinker that interacts just like a human would. It was a poor choice by one programmer that led to horrible and far-reaching unintended consequences. No, I don’t really think Google’s Inbox will enslave us. But I appreciate the irony of life imitating art.
[Bob] built this simple device that can best be described as an electronic float valve. He was wasting a lot of water from overflowing water troughs and buckets around his farm. He would usually put the hose in the container, turn on the water valve and carry on with his work. By the time he remembered to come back, the area would be flooded. It’s obvious that there’s many different ways to solve a problem. For example, a simple mechanical float valve might have worked, but it’s not horse friendly and liable to get damaged soon.
The electronics is unabashedly minimal. An ATtiny85 controls a relay via a common variety NPN transistor. The relay in turn switches the solenoid valve. A push-button tells the microcontroller to start the water flowing, and when the water level gets high enough that it touches two hose clamps, the micro shuts it off again.
There’s some ghetto engineering going on here. The electronics is driven by a 9V battery, although the relay and the solenoid valve that [Bob] used are both rated for 12V. He’s not even using any sort of voltage regulation for the ATtiny, but instead dropping the voltage with a resistor divider. (We wonder about battery life in the long run.)
He built all of it on perf board and stuffed it inside a small enclosure, with two wires coming out for the level sensor and another two for the solenoid, and it seems to work. Check the video below where [Bob] walks through his build.
While some may point out the many short comings in this build, [Bob] found the one solution that works for him. Sometimes the right solution is what you’ve got on hand, and we’re glad he’s hacking away and sharing his work. And check out this wireless water level sensor that he built some time back.

What happens when you have a large stash of clear LED’s but you want or need diffused models for a project? You could go buy some more, but [Tyler] says no! Go grab some scrap from the shop, and make yourself a sand tumbler to diffuse the LED’s you already have.
The tumbler mechanism is similar to a rock tumbler, but is crafted out of bits of wood, some rods, a spaghetti sauce jar, and a DC motor which is available out of the types of machines we already tear apart. Once constructed, fine dry sand and the LED’s are loaded in the jar and is set to tumble for several hours.
Once done its easy to fish out the now diffused LED’s, which have a more even glow over their clear counterparts which shoot most of the light directly out of the end. Although it takes time, its a lot easier than trying to manually diffuse LED’s by hand, and if you need more than just a few its a massive labor saver.
Join us after the break for a quick video showing the results of different attempts during the learning process.

For this Halloween, [Dave Dalton] went all out on his [Rick] costume from the cartoon Rick and Morty. He designed and 3D printed a portal gun. No, not from Portal. Rick’s Portal gun, set for Reality C137.
He built it at Kansas City’s makerspace, called the Hammerspace Workshop. A 3D printed shell closely matches the cartoon depiction of the Portal Gun, but besides looking realistic — it actually works! You see [Dave] actually went and stuffed a pico projector inside so the gun would actually project portals when you use it — with sound effects even.
But our favorite part of the video is probably [Dave’s] excellent imitation of [Rick’s] drunken slurs.
I-i-inside this housing here, we-we-we’ve got all kinds of cool electronic gizmos, we-we got some stuff from Adafruit…

Making stuff is hard, especially when you are making lots of stuff. The OpenMV Cam project knows this, because it has hit a problem while putting together their cheap machine vision module. The problem is with the BGA solder balls that connect the image sensor to the main board.
We’ve covered this intriguing project before: the aim is to build a small, cheap module that can run image processing algorithms to easily give robots sight. The sensor is a Ball Grid Array (BGA) package, which means there are a grid of small solder balls on the back that form the electrical connections. It seems that some of these solder balls are oxidized, preventing them from melting and fusing properly with the board. This is called a head-in-pillow defect, because the ball behaves like your head when you lie down in bed. Your head squishes the pillow, but doesn’t merge into it. There are 38 balls on the OV26040 image sensor and even a single bad link means a failure.
The makers of the project have tried a number of solutions, but it seems that they may have to remake the ball links on the back of each sensor. That’s an expensive process: they say it will cost $7 for each, more than the actual sensor cost initially.
A few people have been posting suggestions in the comments for the project, including using solvents and changing the way the sensors are processed before mounting. We’d like to see them overcome this hurdle. Anybody have any suggestions to quickly and cost effectively move the manufacturing process forward?

Making sound with digital logic usually calls for a Digital to Analog converter. Building one can be very simple, and the sound quality out of an R-2R Ladder is actually pretty good.
In the last edition of Logic Noise, we built up a (relatively) simple VCO — voltage-controlled oscillator — that had roughly one-volt-per-octave response. I even demonstrated it working mostly in tune with another synth’s keyboard. But what if you don’t have a control-voltage keyboard sitting around or you want to combine all of the logic-based circuits that we’ve been building with other circuits under voltage control? That’s where the digital to analog (DAC) voltage converter comes in.

When you have an idea, just go build it. That’s the approach that [GordsGarage] takes with most of his projects, and he’s back in the machine shop again. This time it’s with a rather unique oil candle that uses a spark plug as inspiration. We have to say, the results are on fire.
The spark plug candle was fashioned out of a single piece of 6061 aluminum. To create the scale model, first the stock metal hit the lathe to create the “insulator” section of the plug. From there, he milled in the hex bolt section, then it hit the lathe again to create the threaded section. The inside was bored out to create space for the wick and oil, and then the electrode was installed just above the flame.
This is a pretty impressive scale model and has a great finished look. The only thing that isn’t to scale is the gap for the electrode which is completely necessary to keep the candle from getting smothered. It’s an interesting, unique idea too, which is something that [GordsGarage] excels at. And, if you want to scale his model up a little bit, perhaps you can find some inspiration from this other candle.
