Fresh hacks every day
The folks over at Adafruit have been busy designing an LED matrix wristwatch for a while now. The circuit works great, but since this watch is powered by a coin cell battery, they'd really like to get the power consumption as low as possible. This means they needed a test rig to measure the consumption of each firmware revision, but how exactly do you build a voltage logger that works with … [Read more...]
LED Neurons [Alexandra Olivier] put up an art installation at Wellesley College that looks like a bunch of neurons built out of LEDs. The neurons are connected to a couple PIR sensors and 'fire' whenever movement is detected. The result is a lot like being inside a brain. Fitting, then, that the installation is called Social Synapses. Last year's big toy was always evil, though Last … [Read more...]
[Swake] tipped us off about a collection of old equipment. The site is packed full of various hardware that was used for electrical and chemical testing, metering, and experimentation. You could use this to identify the dinosaurs found in backrooms of college science departments, or draw inspiration from it. The next time you're laying out a panel, or working on a steampunk-ish project go to the … [Read more...]
We're big fans of surface mount parts. SMD components are cheaper, take less board space, and don't require drilling; all the coolest new parts are only available in SMD packages. Smart Tweezers are an advanced multimeter tool specifically designed to test and troubleshoot SMD circuits. It automatically identifies resistors, capacitors, and inductors, and displays the relevant measurements. … [Read more...]
