Bust A Move Doesn’t Have To Be Such A Grind

PC gamers have the benefit of the mouse and keyboard, which are highly flexible when it comes to input devices for gaming. What’s more, the freedom of the platform means that it’s easy to whip up whatever mad controller you can dream of to best suit the games you’re playing. Enter [Tom Tilley] with the aptly-named Hipster Game Controller.

Yes, this is a controller made out of a coffee grinder. The hand-crank setup makes it perfect for imitating the game board in that puzzle classic, Bust-A-Move. [Tom] interfaces the controller in a perfectly hacky way – the scroll wheel from a mouse is removed from the case and zip tied to the shaft of the grinder, allowing the rotation of the grinder to turn the wheel. The mouse wheel is then mapped as the aim control in the game – it really is that simple. An arcade button is also fitted into a mug and wired into the left mouse button to act as the trigger.

[Tom] notes that while you can fill the grinder up while you play, it makes playing the game very hard work. It’s a hacky build to show that sometimes, you don’t need a microcontroller and lines of code – just a mouse, some wire, and a healthy dose of ingenuity.

And, as it turns out, [Tom]’s been quite the Bust-a-Move fan for a few years now. Video after the break.

Dumb Coffee Grinder Gets Smarter with Time

[Forklift] has a Rancilio Rocky, a prosumer-level coffee grinder that’s been a popular mainstay for the last few decades. It’s a simple machine with a direct-drive motor. Rocky has one job, and it will do that job in one of 55 slightly different ways as long as someone is pushing the grind button. What Rocky doesn’t have is any kind of metering technology. There’s no way to govern the grind length, so repeatable results rely on visual estimates and/or an external clock. Well, there wasn’t until [Forklift] designed a programmable timer from the ground up.

The timer interface is simple—there’s a D-pad of buttons for navigation through the OLED screen, and one button to start the grind. The left and right buttons move through four programmable presets that get stored in the EEPROM of the timer’s bare ATMega328P brain. Grind duration can be adjusted with the up/down buttons.

We like that [Forklift] chose to power it by piggybacking on the 240VAC going to the grinder. The cord through the existing grommet and connects with spade terminals, so there are no permanent modifications to the grinder. Everything about this project is open source, including the files for the 7-segment font [Forklift] designed.

Tea aficionados may argue that creating their potion is the more time sensitive endeavor. We’ve got you covered there. Only question is, one button or two?

A 3D-Printed Coffee Grinder

It’s safe to say that a Venn diagram of Hackaday readers and coffee drinkers would have significant intersection, many of you will be lovers of the bean. Some of you will be happy enough with a spoonful of instant granules and a bit of boiling water, but among your number there will undoubtedly be owners of significant quantities of coffee-related machinery and paraphernalia.

If your coffee enthusiasm extends to grinding your own direct from the bean, then [Christian Pederkoff]’s project should hit the mark, he’s created a rather neat 3D-printed coffee grinder. Sadly the creation of a steel burr and ring was beyond his 3D-printing capabilities so those parts come from a commercial grinder, but the housing, shaft coupler and hopper are all from his printer. Power is from a conveniently available source, he’s made use of an automotive windscreen wiper motor. The whole is a straightforward and easy-to-assemble unit that we think would sit well alongside many readers’ coffee making equipment.

If coffee projects are your thing, we have a few for your entertainment. Another not quite so neat enclosure for a coffee grinder, for example, or a tea-light-powered filter coffee machine for power cut beverage satisfaction.

Cute but Serious-Faced Automata Produce a Pour Over

robot-cafe-cartCheck out the great workmanship that went into [TonyRobot]’s coffee vending version of ROBOT CAFE at Tokyo Maker Faire 2016. We’d really like to see this in action, so if anyone has more success than we did at tracking down more info (especially if it’s video) let us know in the comments below. We spot laser-cut wood making up the clever scoop design (and the numerous gears within it) but simply must know more.

Technically this is less “robot” and more “automata“. The cart charmingly fuses vending machine practicality with a visual display… and a great one at that. The aesthetic of the Robot Cafe leaps over the uncanny valley and fully embraces lovable robot faces.

Coffee is ground by a manual-style grinder into a scoop, which is then dumped into a pour-over filter. The hot water is then raised from below to pour over the grounds. These characters can be reconfigured based on the needs of the venue. The creator page linked above has three pictures of the same cart and same robo-baristas, but they are fishing for sodas instead. The glass bottles are lifted through the hole you can see on the right of the cart’s counter, using a fishing line with a magnet to grip the metal bottle cap.

We were delighted when robot vending machines started to appear — the kind with a big glass window and a gantry that grabs your corn-syrupy beverage. But take inspiration from this. True vending nirvana is as much theater as it is utility.

Laminated wooden case brings a dropped coffee grinder back from the junk heap

coffee-grinder-fix

Instead of giving it up for dead, [Suprise Pink Mist] fabricated a replacement case for the motor and blade of his broken coffee grinder. The original enclosure was made of plastic, which didn’t survive being dropped. There isn’t an image of what those plastic parts looked like, but we have to think they were nowhere near as neat as the replacement.

The first step was to cut a set of plywood discs to the approximate outside dimensions. Since the base of the motor has several different diameters each disc had a void cut out of its center to match. The image to the right shows the motor sitting upside down next to the stacked plywood. The black electrical tape seals around the mason jar ring which was a perfect friction fit with the original bowl of the grinder. Once everything was glued together the outside edges were flattened on a belt sander and the mason jar was screwed in place to house the beans during grinding.
