Design Considerations
Log from Open Indirect Ophthalmoscope
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...

NeuroBytes v0.92 Prototype
Log from NeuroBytes
Today, the NeuroBytes project takes its first baby step into the 21st century.Okay, ignore the extremely sketchy construction techniques. It's an STM32F0 Discovery board, chosen due to its extremely low cost (under $10) and built-in ST-LINK programmer....

Nginx and Memcached
Log from FLED
With FLED we are trying to make a visualization platform, somewhere all our apps and monitoring tools can send data and where we can then use that data to make interesting visualizations.As such we need to be able to accept data from a variety of sources...

The Design And Construction Of A Backplane
Log from MC68000 Computer
This entire project is a little bit of an odd bird. In terms of electronic sophistication, it’s not too different than any of the other homebrew computers you might see on Hackaday. This isn’t a project that will just sit on my workbench until I die...

Theory of a CPU module
Log from MC68000 Computer
Compared to the 8080, the Z80, the 6809, 6502, and all the other 8-bit microprocessors used in boxxen of yore, the CPU I’m using for this project - the Motorola 68000 is both extremely powerful and extraordinarily complex. The power comes from a huge...

A Long, Long Overdue Update
Log from MC68000 Computer
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...

Prototype and Firmware Complete
Log from "Chad" - The NFC Voting System
I'm happy to report that I have finished the hardware prototype and have the first full version of the firmware done.→InsertImageThat turns out to be a lot of wires. From left to right is the PN532 NFC reader, Arduino, and breadboard. On the breadboard...

Soldering Complete
Log from "Chad" - The NFC Voting System
→InsertImageSo here's the deal. One of my prejudices against Arduino is that it's an expensive board to leave with a project. But this is kind of a one-time thing so I was happy to find the Seeed Studio protoype shield for like $7.95 at the local Radio...

power....
Log from LayerOne 2014 Conference Badge
Arko started putting the rev3 board together last night, we usually build the power section first and measure how it looks, make sure none of the power is shorted in the PCB ( it happens). This board has one always on regulator, its a 3.3V LDO that...

LF Antennas arrived from PCB house
Log from LayerOne 2014 Conference Badge
Just took them out of the box, need to test them and see if they've worked, RF is black magic.The other boards are also out for manufacturing. They should be here this week , hopefully since we have to pre-build a bunch!

anticipation, neoden, parts ordering, BOM.
Log from LayerOne 2014 Conference Badge
we're still waiting on a tracking number for the PCB's, the conference is in just over a week! and i can't finish the code til we get the first one made... oddly enough this hasn't been the closest we've cut it, but its getting there.since there...

fedex and wildfires
Log from LayerOne 2014 Conference Badge
It's wildfire season, but Fedex managed to get our boards from Malaysia to us in good time, unfortunately there was a cock up in the ordering department and they shipped to the billing address, we'd left there about 15 minutes before they showed up with...

First Steps
Log from Analog CPU Gauge
My first steps were to get my hands on a motor. I started with the X27.168 motor, seen here. There are a couple of variants of these motors. The 168 motors have the pins exiting on the back of the motor, while the drive shaft exits on the front....

Prototypes ahoy
Log from Analog CPU Gauge
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...

Designing a PCB
Log from Analog CPU Gauge
I designed my PCB in my favorite software - Diptrace. The motor footprint from switec's datasheet was missing a few key dimensions. It took a bit of measuring with a caliper and calculating hole sizes, but I was able to get all the dimensions correct...
