If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current …read more Continue reading Driving a Laser at 200 Volts for Nanoseconds
By virtue of its triple bond, acetylene burns hotter than any other common hydrocarbon when mixed with oxygen, but it isn’t the only flame hot enough for welding. With the …read more Continue reading Welding with Natural Gas and Oxygen
Nautical navigation has a long history of innovation, from the compass and chronometer to today’s computer-driven autopilot systems. That said, the poor compatibility of electronics with saltwater has consequently created …read more Continue reading A Ruggedized Raspberry Pi for Sailors
If you’re planning to make a metalworking lathe out of a CNC milling machine, you probably don’t expect getting a position sensor to work to be your biggest challenge. Nevertheless, …read more Continue reading Turning a Milling Machine into a Lathe
One of the great things about sharing hacks is that sometimes one person’s work inspires someone else to take it even further. A case in point is [Ivor]’s colorimeter hacking …read more Continue reading Further Adventures in Colorimeter Hacking
The rotary evaporator (rotovap) rarely appears outside of well-provisioned chemistry labs. That means that despite being a fundamentally simple device, their cost generally puts them out of reach for amateur …read more Continue reading Building a Rotary Evaporator for the Home Lab
Much of the expense of developing AI models, and much of the recent backlash to said models, stems from the massive amount of power they tend to consume. If you’re …read more Continue reading Image Recognition on 0.35 Watts
When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they can reach extremely fine …read more Continue reading Designing an Open Source Micro-Manipulator
In the 1930s, as an alternative to celluloid, some Japanese companies printed films on paper (kami firumu), often in color and with synchronized 78 rpm record soundtracks. Unfortunately, between the …read more Continue reading The Challenges of Digitizing Paper Films
A business card is a convenient way to share your contact information, but it’s unfortunately prone to being thrown away or forgotten. PCB business cards try to get around this …read more Continue reading Building a Macro Pad into a Business Card
