While it might be nice to use a $4,000 oscilloscope in a lab at a university or well-funded corporate environment, a good portion of us won’t have access to that kind of equipment in our own home shops. There are a few ways of getting a working oscilloscope without breaking the bank, though. One option […]
Historically, getting files on to a microcontroller device was a fraught process. You might have found yourself placing image data manually into arrays in code, or perhaps repeatedly swapping SD cards in and out. For select Arduino boards, that’s no longer a problem – thanks to the new TinyUSB library from Adafruit (Youtube link, embedded […]
It’s a very brave person who takes a Dremel or similar to the case of their svelte new laptop in the quest for a new connector, it sounds as foolhardy as that hoax from a while back in which people tried to drill a 3.5mm jack into their new iPhones. But that’s what [BogdanTheGeek] has […]
Earlier this month a single person pleaded guilty to taking down some computer labs at a college in New York. This was not done by hacking into them remotely, but by plugging a USB Killer in one machine at a time. This malicious act caused around $58,000 in damage to 66 machines, using a device […]
What if there were something like a KVM switch for your micro programmer, logic analyzer, and other various tools? There was a time when KVM switches (keyboard, video, and mouse, by the way) were metal enclosures surrounding an absurdly complicated rotary switch. This fact has a few applications if you ever want to switch a […]
The keyboard and mouse are great, we’re big fans. But for some tasks, such as seeking around in audio and video files, a rotary encoder is a more intuitive way to get the job done. [VincentMakes] liked the idea of having a knob he could turn to adjust his system volume or move forward and […]
DC power bricks were never a particularly nice way to run home electronics. Heavy and unwieldy, they had a tendency to fall out and block adjacent outlets from use. In recent years, more and more gadgets are shipping with USB ports for power input. However, power over USB has always been fraught with different companies […]
Just for the challenge, just for fun, just for bragging rights, and just to do a little showing off – all perfectly valid reasons to take on a project. It seems like one or more of those are behind this tiny ESP32 board that’s barely larger than the coin cell that powers it. From the […]
