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...
So we had an idle Friday afternoon here at SupplyFrame HQ and our evil overlord Alek asked us to build something cool for the office.With the restriction of only having a day to build we didn't have many choices in what we could source components for,...
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...
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...
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...
After much soldering....and a little debugging we managed to get the array lit up.If you look carefully you can see the grounding braid we used as a power and ground bus at either end of the strips. We then simply hooked up data and clock (these are...
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...
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-...
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...
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...
