A working display!
Log from FLED
Finally Ivan screwed the backboard into place. One of the great things about using Foamed PVC is you can basically treat it like wood, it holds a screw well and is easy to cut and saw.With our fingers crossed we switched it on, and to our delight we...

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...

Power And Reset Circuits
Log from MC68000 Computer
Since we're using an ATX power supply for this computer, there is a little magic that needs to happen before it becomes a proper power supply. Besides the usual orange, red, yellow and black wires attached to a 20-pin connector, there are also a few...

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...

Theory of RAM and ROM modules
Log from MC68000 Computer
Although it might make sense to start this project by building a CPU module first, I decided it would make more sense to start with the memory for this system. This serves two purposes: as an explanation of how the 68000's memory-mapped I/O works, and...

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...

You can refactor hardware, right?
Log from MC68000 Computer
I'm in the middle of a few free days right now, and I figured it's time to take a look at this project. Things aren't good. Let's go over what's wrong with it:It's not doneIt's not even close to being doneThe 'not being done' is mostly a result of using...

Dev Tools
Log from "Chad" - The NFC Voting System
I'm exploring the STM32 F3 for this project:→InsertImageLinux Setup→InsertImage- Toolchain: GNU Tools for ARM→InsertImage- Bare metal template→InsertImage- OpenOCD Git repo: git://git.code.sf.net/p/openocd/code→InsertImageTexane Repo:→InsertImage-...

PN532 Reader
Log from "Chad" - The NFC Voting System
Project deadline is 17 days away.→InsertImageThe ElecFreaks PN532 based NFC reader arrived today. Had I realized that all their software samples are derived from the Adafruit board I would have ordered that one to support the open source effort (sorry...

MiFare Write/Read Success
Log from "Chad" - The NFC Voting System
Days until deadline: 16→InsertImageI still don't have the correct tag in hand yet (ntag203). But today I was able to write an NDEF formatted message to the MiFare Classic tag that came witdh the NFC reader. This was all thanks to the Seeed Studio PN532...

Full Proof of Concept
Log from "Chad" - The NFC Voting System
Days until deadline: 13→InsertImageI have had a few productive nights of coding and now have a working proof of concept. After arriving home from holiday at in-laws house I was happy to see the NTAG203 samples I had ordered had arrived while I was gone....

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...

Let's build this thing
Log from "Chad" - The NFC Voting System
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...

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...
