Collaborate Disseminate
Art is a funny thing. Sometimes, it’s best done in a one-off fashion and sold for a hugely inflated price. Othertimes, it’s more accessible, and it becomes desirable to sell …read more Continue reading Tricks For Mass-Producing Laser-Etched Art
Not every project has to be an AI-powered particle accelerator using lasers. Sometimes simple projects can be very satisfying, and a simple project can be a great gateway to introduce …read more Continue reading A Bubble Machine Built from Scrap
That’s funny. I could have sworn I didn’t run a print job yesterday… but will you look at that? Continue reading What’s *THAT* on my 3D printer? Cloud bug lets anyone print to everyone
If you have a Raspberry Pi and have any interest in its peripherals, you may be familiar with the grinning pirate logo of the British company, Pimoroni. The Sheffield, UK based outfit first established a niche for itself as one of the go-to places for much of the essentials of Pi ownership, and has extended its portfolio beyond the Pi into parts, boards, and components across the spectrum of electronic experimentation. Their products are notable for their distinctive and colourful design language as well as their constant exploration of new ideas, and they have rapidly become one of those companies …read more

Food. A necessary — often delicious — interruption of whatever project you’re currently hacking away at. Ordering takeout gets expensive and it’s generally unhealthy to subsist solely on pizza. With the Sandwich-O-Matic, a simple voice command fulfills this biological need with minimal disturbance of your build time.
Built for a thirty-six hour hackathon, the Sandwich-O-Matic is controlled by a Photon and an Arduino. The backend is running node, hosted on AWS, and Google Cloud was used for voice to text recognition. This thing is a fully automated and voice controlled sandwich building station. A DC motor services the toaster, while …read more

So, wether you’ve blown your house’s breakers while cranking up the power on your latest project or a storm has brought low the local power grid, what do you do if you desperately need coffee with no electricity to power your coffee maker? Make like [austiwawa]: crack it open and bust out the tea lights.
Removing the bottom of the coffee maker is simply done, exposing the resistance heating element. Improvising a jig to hold the coffee maker over an arrangement of five tea lights, the candle flames slowly do the work of heating the element to set the maker …read more
Can you make a spectrometer for your home lab all from materials you have sitting around? We might not believe it from a less credible source, but this MIT course does indeed build a spectrometer from foam board using two razor blades as the silt cover and a writable CD as the diffraction grating. The coolest part is removing the metal backing of the CD.
Hackaday reader [gratian] tipped us off about the course available from MIT courseware called Nanomaker. It boils down some fairly complicated experiments to the kind one can do in the home lab without involving thousands …read more

A personal bartender is hard to come by these days. What has the world come to when a maker has to build their own? [Pierre Charlier] can lend you a helping hand vis-à-vis with HardWino, an open-source cocktail maker.
The auto-bar is housed on a six-slot, rotating beverage holder, controlled by an Arduino Mega and accepts drink orders via a TFT screen. Stepper motors and L298 driver boards are supported on 3D printed parts and powered by a standard 12V DC jack. Assembling HardWino is a little involved, so [Charlier] has provided a thorough step-by-step process in the video after …read more

When I start up a new project, one that’s going to be worth writing up later on, I find it’s useful to get myself into the right mindset. I’m not a big planner like some people are — sometimes I like to let the project find its own way. But there’s also the real risk of getting lost in the details unless I rein myself in a little bit. I’m not alone in this tendency, of course. In the geek world, this is known as “yak shaving“.
The phrase comes obliquely from a Ren and Stimpy episode, and refers to …read more
