Many of us will own a lithium-ion power pack or two, usually a brick containing a few 18650 cylindrical cells and a 5 V converter for USB charging a cellphone. They’re an extremely useful item to have in your carry-around, for a bit of extra battery life when your day’s Hackaday reading has provided a […]
There was a time when a decent temperature controlled soldering iron took the form of the iron itself and a box of electronics, but now it’s just as likely to be a miniaturised affair with the temperature controller built into a slim and lightweight handle. Irons such as the Miniware TS series have become firm […]
It’s badgelife season, and if you need an idea for a killer piece of wearable electronics, look no further than this PCB Tesla coil. Yes, it’s killer, doubly so if you’re wearing a pacemaker. This project was inspired by an earlier Tesla coil on a PCB project that used 160 turns of 6 mil traces […]
Join us Wednesday, April 17 at noon Pacific time for the 2019 Hackaday Prize Hack Chat! The 2019 Hackaday Prize was just announced, and this year the theme is designing for manufacturing. The hacker community has come a long, long way in the last few years in terms of the quality of projects we turn out. […]
Since the Pi Zero was released, there have been many attempts to add a power bank. Cell phone batteries are about the same size as a Pi Zero, after all, and adding a USB charging port and soldering a few wires to a Pi is easy. The PiSugar is perhaps the cutest battery pack we’ve […]
The common garden slug is a mystery. Observing these creatures as they slowly emerge from their slimy lairs each evening, it’s hard to imagine how much damage they can do. With paradoxical speed, they can mow down row after row of tender seedlings, leaving nothing but misery in their mucusy wake. To combat this slug […]
This is the 2019 Hackaday Prize, the worldwide hardware design contest focused on product development. We know you can build a working prototype, and we still want to see you do that. But a great idea should have reach beyond your own workshop. This year’s Hackaday Prize is about taking your product across the finish […]
My first full day in China was spent at Electronica, an absolutely massive conference showcasing companies involved in electronics manufacturing and distribution. It’s difficult to comprehend how large this event is, filling multiple halls at the New International Expo Center in Shanghai. I’ve seen the equipment used for PCB assembly many times before. But at […]
