Join editors Elliot Williams and Mike Szczys as they unpack all the great hacks we’ve seen this week. On this episode we’re talking about laser Internet delivered from space, unwrapping the complexity of Charlieplexed circuits, and decapping ICs both to learn more about them and to do it safely at home. We have some fun […]
This year we’ve added something new and exciting to the Hackaday Prize mix. Mentor sessions link up hardware teams with experts from backgrounds useful in moving their product development forward. We’ve assembled a dream team of mentors, and today we’re excited to publish video of the first mentor session which you’ll find embedded below. It’s […]
When I went to a hacker camp in the Netherlands in February I was expecting to spend a few days in a comfortable venue with a bunch of friends, drink some beer, see a chiptune gig, and say “Ooh!” a lot at the exciting projects people brought along. I did all of those things, but […]
Espressif, the company behind the extremely popular ESP8266 and ESP32 microcontrollers has just announced their latest chip. It’s the ESP32-S2. It’s a powerful WiFi-enabled microcontroller, and this one has support for USB OTG. Compared to the ESP32 we know and love, there are a few differences. The ESP32-S2 uses a single core Xtensa LX7 core […]
Whatsapp allows for end-to-end encrypted messaging, secure VoIP calls, and until this week, malware installation when receiving a call. A maliciously crafted SRTCP connection can trigger a buffer overflow, and execute code on the target device. The vulnerability was apparently found first by a surveillance company, The NSO Group. NSO is known for Pegasus, a […]
Join us Thursday at noon Pacific time for the OSH Park Hack Chat with Drew and Chris!Note the different day from our usual Hack Chat schedule! Printed circuit boards have been around for decades, and mass production of them has been an incalculable boon to the electronics industry. But turning the economics of PCB production […]
Cheap nostalgia, that’s the name of the game. If you can somehow build and ship ‘cheap nostalgia’, you’re going to be raking in the bucks. For the ‘musicians’ in the crowd, the king of cheap nostalgia has something great. Behringer is cloning the Yamaha CS-80. and it was announced at this month’s Superbooth. The Yamaha […]
Join Mike Szczys and Elliot Williams as they riff on the coolest hacks from the past week. Clocks and 3D printing seem to keep coming up this week as we look at using an FPGA plus GPS receiver for better accuracy than we’re used to, and we haggle over what to call the robot arms […]
In the first part of this series, we took a look at a “toy” negative-differential-resistance circuit made from two ordinary transistors. Although this circuit allows experimentation with negative-resistance devices without the need to source rare parts, its performance is severely limited. This is not the case for actual tunnel diodes, which exploit quantum tunneling effects […]
