Collaborate Disseminate
At this point, there are no shortage of impressive hacks for the Raspberry Pi. [Dilshan Jayakody] recently documented his experience in designing and building an inexpensive FM Stereo Receiver for …read more Continue reading An Inexpensive FM Receiver for the Raspberry Pi
The white cane (and its many variants) is an everyday carry for many visually impaired people. This low-tech tool allows those afflicted by visual impairment to safely navigate the world …read more Continue reading A Digital White Cane for the Visually Impaired
We’re always pleased to see one of our community’s projects succeed, and we celebrate that success in whatever what it comes. But seeing a company launched to commercialize an idea that started as a Hackaday.io project and a Hackaday Prize entry is especially gratifying. So we were pleased as punch …read more
Can you electronically enhance your brain? I’m not talking about surgically turning into a Borg. But are there electronic methods that can improve various functions of your brain? Fans of brainwave entrainment say yes.
There was an old recruiting ad for electrical engineers that started with the headline: The best …read more
If you’ve ever engaged in social media, you’re familiar with the little thrill you receive when your post, tweet, or project gets a like. But, if logging in feels like too much overhead to obtain your dopamine reward, [pt’s] CircuitPython Hackaday portal may be just what you’re looking for. This project creates a stand-alone counter to display the number of “skulls” (aka likes) received by a project on hackaday.io, and of course, it’s currently counting its own.
The code is running on a SAMD51 (Cortex M4) microcontroller and serving up the skulls on 240×320 TFT display. For WiFi connectivity, the …read more
In your living room, the big display is what you want. But in an embedded project, often less is more. We think [bobricius] will agree since he submitted a tiny 4×5 LED display into our square inch challenge. The board features an ATtiny CPU and twenty SMD LEDs in a nice grid. You can see them in action, scrolling to some disco music in the video below.
There is plenty of room left in the CPU for bigger text strings — the flash memory is just over 10% full. A little side-mounted header makes it easy to program the chip …read more

We are anxious to see the finished product of [Mark Omo’s] entry into our one square inch project. It is a 20 megasample per second oscilloscope that fits the form factor and includes a tiny OLED screen. We will confess that we started thinking if you could use these as replacements for panel meters or find some other excuse for it to exist. We finally realized, though, that it might not be very practical but it is undeniably cool.
There are some mockup PCB layouts, but the design appears feasible. A PIC32MZ provides the horsepower. [Mark] plans to use an …read more
No, we’re not talking about spooky feats of General Relativity. But you should know that the Return of the Square Inch Project just got its deadline extended.
If you missed the call the first time around, our favorite user-contributed contest on Hackaday.io is up and running again. Hackaday.io tossed in some good money for prizes, and folks started thinking about what functionality they could cram inside a 25.4 mm x 25.4 mm square. But while one constraint can help bring out creativity, adding a tight deadline to a tight squeeze caused a number of our entrants to ask for an …read more

FPGAs have gone from being a niche product for people with big budgets to something that every electronics experimenter ought to have in their toolbox. I am always surprised at how many people I meet who tell me they are interested in using FPGAs but they haven’t started. If you’ve been looking for an easy way to get started with FPGAs, Hackaday’s FPGA boot camp is for you. There’s even a Hackaday.io chat in the group specifically for FPGA talk for questions and general discussion!
While it is true FPGAs aren’t for everything, when you need them you really need …read more

If you doubt the power of the Hackaday community, check this one out. Stalwart reader and tipster [starhawk] has pitched in to help a friend in need, someone he met through Hackaday.io. Seems this friend’s current living arrangements are somewhat on the cramped side, and while he’s in need of a PC, even a laptop would claim too much space.
So with a quick trip to the store and a few items from the junk bin, [starhawk] whipped up an all-in-one PC the size of a tablet for his friend. As impressed as we are by the generosity, we’re more …read more
