Hey all!This is another project log to update the latest developments of OWL (Just in case you forgot, we call it OWL because, well, Open Indirect Ophthalmoscope, OIO).So, since the last time I made a log, we’ve been working on--making an elegant GUI...
Earlier version of the device was reconsidered in terms of following aspects:• Accommodating for different refractive errors • Aesthetics • Ergonomics • Weight distribution OIO ASSEMBLY EXPLODED ASSEMBLY1. ACCOMMODATING FOR DIFFERENT REFRACTIVE ERRORS...
7/29/2013: As I stated; been working on the cabinet for the Mirror universe project. I bought a couple of "project" Bally Star Treks from a fellow pinball collector out of Shertz a few years ago. These have been setting in storage for a while... and...
Quick story. I brought this computer to the Vintage Computer Festival 9.1 last year to show Bil, Dave, and all the other cool people at the event. At the time, I was freerunning the processor, watching the blinkenlight count up. Great stuff, and proof...
Mechanical assembly always takes longer than I think it will. I figured one evening would be all it takes to build this thing, but by the time I figured out the size of the acrylic, cut a wood base for it, tested the layout of the components, then drilled...
After delays, e-test errors, shipping problems, wild fires and 6 revisions. These completely untested hopefully 4 layer PCBs have arrived. I'm probably just being paranoid but they sure look like 2 layer.Also Arrow decided that I didn't want overnight...
With motors in hand, I built up a quick prototype. The X27 motors are designed to only move a small pointer. They draw so little current (under 20ma at 5v) that they can be driven by PIC and AVR micro pins directly. Soldering wires to the thin pins of...
Sooo.... I've been entertaining some new projects due to some recent test cases and I've determined it would be just as easy to update this beast of a project. Current update list:Change the LED type to the WS2812 that we love to use so...
In three words, Hackers love clocks. Not only do we think that digital watches are still a pretty neat idea, we love all manner of timepieces. This episode of The Hacklet focuses on the clock projects we've found over on Hackaday.io.We start with [rawe]...
Hey, did you know that Hackaday.io is continuously being updated and improved? One of the coolest features this week is the new LaTeX based equation editor. That's right, you can now put symbols, equations, and all sorts of other LaTeX goodies into your...
For every computer error, there are two human errors, and one of them is blaming the computer. Whenever a human blames a computer for something, there are two tools, and one of them is the computer.Not all of your nifty tools need to be fancy robots,...
Just about every hacker, maker and tinkerer out there received their early education the same way: A screwdriver in one and a discarded bit of electronics in the other. There is no better way to find out how something works than cracking it open and...
Sooner or later, all of us end up putting on our reverse engineering hats and digging in to a device. It might be that you're trying to keep an old piece of equipment running – the manufacturer is long defunct, and parts are no longer available. It might...
They say necessity is the mother of invention. Have you ever been right in the middle of a project, when you realize that you could hack up a simple tool which would make your current task easier? Maybe it’s a coil winder, or a device to hold .100 headers...
Everyone’s first microcontroller project is making an LED blink. It’s become the de-facto “Hello World” of hardware hacking. There’s something about seeing wires you connected and the code you wrote come together to make something happen...
