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...
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...
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...
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-...
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....
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...
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...
→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...
