This log includes major upgrades included in the current system.Till now we had been using an older OS incompatible with RPi 3 since the display could have only worked with that image. Additionally it caused the trouble where the onboard or external...
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...
Now we wanted this display to look really sweet since it will be on our office wall for some time to come. To make it look gorgeous we decided to make the frame out of white foamed PVC board, and the front diffuser out of 1/4" thick white acrylic.First...
To drive this system we decided to use a Raspberry Pi and Arduino Micro combination.The Raspberry Pi runs a stack of Nginx, Memcached and NodeJS which then feeds desired LED colors to the Arduino Micro which streams them out over the WS2811 protocol...
The display is looking great, but we really need to make this into more than just a pretty rainbow colored matrix.To do this we decided we wanted to be able to open up the control of the lights to all our developers, and we want to be able to feed data...
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...
We still haven't had time to finish this off completely yet. We do have the driving system working, but its not yet stable and its not yet in the box.In the meantime we figured we'd post some more assembly photos. So here's Jasmine...laying out 1758...
Finally, after much fiddling around, the upgrade to FLED is operational.We're now running a grand total of 1768 LEDs, in a 52x34 configuration. The setup is a Beaglebone Black connected to an RGB-123 48 output cape. The cape level shifts the Beaglebone...
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...
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...
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...
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...
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...
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...
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...
