When it comes to home-lab reflow work, there are a lot of ways to get the job done. The easiest thing to do perhaps is to slap a PID controller …read more Continue reading A Compact SMD Reflow Hotplate Powered by USB-PD
Bigfoot Turns Classic Sewing Machine into a Leather-Eating Monster
If you try to sew leather on a standard consumer-grade machine, more often than not you’ll quickly learn its limits. Most machines are built for speed, and trying to get …read more Continue reading Bigfoot Turns Classic Sewing Machine into a Leather-Eating Monster
Solder Two Boards at Once With This Dual Reflow Plate
Homebrew reflow projects generally follow a pretty simple formula: find a thrift shop toaster oven or hot plate, add a microcontroller and a means to turn the heating element on …read more Continue reading Solder Two Boards at Once With This Dual Reflow Plate
Start Your Semiconductor Fab with This DIY Tube Furnace
Most of us are content to get our semiconductors from the usual sources, happily abstracting away the complexity locked within those little epoxy blobs. But eventually, you might get the …read more Continue reading Start Your Semiconductor Fab with This DIY Tube Furnace
Internal Heating Element Makes These PCBs Self-Soldering
Surface mount components have been a game changer for the electronics hobbyist, but doing reflow soldering right requires some way to evenly heat the board. You might need to buy …read more Continue reading Internal Heating Element Makes These PCBs Self-Soldering
Stewart Platform Keeps Its Eye on the Ball
Although billed as a balancing robot, [Aaed Musa’s] robot doesn’t balance itself. It balances a ball on a platform. You might recognize this as something called a Stewart platform, and …read more Continue reading Stewart Platform Keeps Its Eye on the Ball
This Found-Sound Organ Was Made with Python and a Laser Cutter
Certain among our readership will no doubt remember attaching a playing card to the front fork of one’s bicycle so that the spokes flapped the card as the wheel rotated. …read more Continue reading This Found-Sound Organ Was Made with Python and a Laser Cutter
PET Bottles Diligently Turned Into Filament
