From XOR to MUX
Log from Hackaday TTLers
You might remember my musings with the XOR gate with interlocked NPN transistors discussed at Bipolar XOR gate with only 2 transistors But thinking about how XOR is done with pass transistors in CMOS and the structure often creates a MUX, I wondered...

Solving Towers of Hanoi recursively in 80 nibbles
Log from Exploring the Science Fair Microcomputer Trainer
As Michael mentioned, he somewhat nerd sniped me with the the idea of squeezing a Towers of Hanoi solver in not the Science Fair Microcomputer Trainer. As an avid fan of both the Gakken FX R-165 and the Science Fair Microcomputer Trainer, I could't let...

Analogue Wind Vane With Auto Set Up
Log from Arduino GPRS IOT Weather Station
As the amazing online GPRS Weather Station project continues, we have yet another upgrade to the vast array of sensors with a professional analogue wind vane, kindly donated by Vector Instruments. This device will eventually be hooked into the new, upgraded,...

Pt.1 Sensor Design and Prototyping
Log from WiFi-Enabled Visual Doorbell
Full video on this subject (this is literally the script): https://www.youtube.com/watch?v=Psy6lRcdGtk Introduction Old houses, like my parents’ home, comes wired with simple electromechanical doorbells. They’re a simple electromagnet with a metal...

Jasmine Brackett Hello Everyone. Welcome to this week's Hack Chat! !!!Bhavesh Kakwani WooShulie: Welcome!! We have tons of questions in our sheet already! https://docs.google.com/spreadsheets/d/1ZHahHN4kU0YBjMgrZMU9ntrmdDD8JOUmpHX2mR6Ok0w/edit#gid=0Jasmine...

FLED
Log from FLED
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,...

Adding the electronics
Log from FLED
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...

Software stack
Log from FLED
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...

Oh No! *Pop*
Log from FLED
So just after presidents day we came back into the office and found that the FLED was dead! Turned it on and nothing happened. After eliminating the ATX PSU from the equation it became clear we would need to pull the display down and open it up to find...

A new start....
Log from FLED
So the LEDs have died again. Typical really, we fixed them up just two days ago replacing another blown unit, but it once again died. These really have been the worst LEDs I have ever encountered, bright and cheap, but completely unreliable.Therefore...

1728 leds is a lot more data than you think
Log from FLED
In the original FLED implementation we had a Raspberry Pi inside the case. This Pi ran a NodeJS application that executed the animation code written in JavaScript and provided a web interface for users to create animations within. This all worked fairly...

It's alive!
Log from FLED
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...

Animations!
Log from FLED
So after you have a working LED matrix, you can't stop there. Otherwise you just have a big display running strandtest and that frankly just sucks.We built a Javascript animation engine that we use to drive the display, this runs NodeJS which allows...

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...

BLINKENLIGHTS
Log from MC68000 Computer
This is something I've written about in a front page Hackaday post, but I think it's time to go over a little more of the theory of what I'm doing here. First, a video:This is called freerunning the processor. Basically, it executes one instruction,...
