It is a well-known reality of rescuing certain older electronic devices that, at some point, you’re likely going to have to replace a busted capacitor. This is the stage [Kevin] is at in the 3rd installment in his saga of reviving a 50-year-old Military Tektronix oscilloscope. [Kevin] recently discovered a failed capacitor in the power […]
Today in old school nostalgia our tipster [Clint Jay] wrote in to let us know about this rotary dial. If you’re a young whippersnapper you might never have seen a rotary dial. These things were commonly used on telephones back in the day, and they were notoriously slow to use. The way they work is […]
This project, sent in by [Henk], goes through a few different ways to make a solder stencil using a vinyl cutter, a CO2 laser, and a fiber laser. The project starts with identifying a method to convert the board’s Gerber files to a PNG, which is ultimately used to create a vector file for use […]
[Kalesh Sasidharan] from Sciotronics wrote in to tell us about their project, Stamp: a modular set of template breakout boards designed to make prototyping with SMD components faster, easier, and more affordable. No breadboards, custom PCBs, or tangled jumper wires required. The project has blasted past its Kickstarter goal, and is on track to start […]
If you’re into retro CPUs and don’t shy away from wiring old-school voltages, [Mark]’s latest Intel 8080 build will surely spark your enthusiasm. [Mark] has built a full system board for the venerable 8080A-1, pushing it to run at a slick 3.125 MHz. Remarkable is that he’s done so using a modern Microchip FPGA, without vendor […]
If you’ve ever squinted at a DE10-Nano wondering where the fun part begins, you’re not alone. This review of the Mr. MultiSystem 2 by [Lee] lifts the veil on a surprisingly noob-friendly FPGA console that finally gets the MiSTer experience out of the tinker cave and into the living room. Developed by Heber, the same […]
Business cards are a simple way to share contact information, but a memorable design can make them stand out. [Jeremy Cook] has been experimenting with adding artistic finishes to PCBs, and has recently applied what he’s learned to make some unique business cards. His write-up consolidates some great resources to get you started in making […]
We’ve all made a few bad PCBs in our time. Sometimes they’re recoverable, and a few bodge wires will make ’em good. Sometimes they’re too far gone and we have to start again. But what if you could take an existing PCB, make a few mods, and turn it into the one you really want? […]
We all appreciate clear easy-to-read reference materials. In that pursuit [Andreas] over at Splitbrain sent in his latest project, Pinoutleaf. This useful web app simplifies the creation of clean, professional board pinout reference images. The app uses YAML or JSON configuration files to define the board, including photos for the front and back, the number […]
