About a year ago, I created a sculpture titled "Moth Electrolier" (2018) in which I used animated LEDs to represent the trails of moths flying around a bulb at night. Here's a video on Vimeo:This post is about the design of a bus to drive trails of individually...
So it's been a while since I actually did anything on breadWare, but it's always been in the back of my mind and everything I've worked on since has been helpful in figuring out how I should approach this next revision. I haven't routed any traces yet...
A lot of the hardware design is done now and I've sent a couple of PCBs off, so I can document the various bits. Here's the ALU: There are two 64K x 8 EEPROMs, each generating 4 bits of the result. Both ROMs use the same image, but A15 is pulled low...
The following is a non-programmer's attempts to integrate python scripts from Jay Doser into our project using a Raspberry Pi, an H-bridge and an IMU. As you can see, it's in Spanish so if you wish help with the translation, please feel free to contact...
The WizYasep (currently) implements an application-specific network protocol that is simple (hence cheap and easy to use) yet efficient and flexible. Unlike other widely used protocols, WizYasep synchronises the displays very finely to prevent "tear/shear"...
In 2021, a friend of mine gave me an Apple //e that he'd had sitting in a garage for years. He'd rescued it from a place where another one of my friends had been working, probably around 1996. I've spent a few months cleaning and fixing it up; part of...
MCU Pretty early on, I had decided to try using an ESP8266 to drive all the functions of my clock designs. I had already used an ESP01 to provide network connectivity for an Arduino-based clock, and that had always seemed a bit like the tail wagging...
Introduction There's a lot of room for paranoia when stepping from the digital domain with its noise margins, supply ripple and voltage tolerances into areas of analog and mixed signal circuitry. Connectors, analog switches, scaling networks, voltage...
If you've looked at the price of high end graphics cards recently (2018) you'll quickly realise that it will be much more cost effective to rent one in a cloud for $3 an hour. I rented a Tesla 16Gb P100 which has a list price of about $6,000 dollars!...
Project update:What a RIDE this week has been! Every once and a while you put a thing down into the EDA, shoot it off to production buy all the parts everything comes and the thing comes out working, EXACTLY like you thought it would! I...
I have finally fulfilled a goal I had since my original BluePOT project back in 2019 - to add Caller ID support. I know that it's not used by very old phones but I always felt it had to be there for me to claim my gadget was a good replica...
Sensors selection Depending on the sensors you have soldered to your board you will have to comment/uncomment a few lines of code... Open the GTW1 .ino file Full Weather Station Here is the sensors selection for my "full weather Station" //sensors selection...
Now it's finally time to replace the tub and shower combination faucet. My motivation for the replacement is (a) to move from separate hot and cold controls to a single handle, and (b) move from ancient rubber washer technology to modern washerless goodness....
Stephen Tranovich12:04 PMOkay, let's get started! A BIG welcome to @Al Williams for coming on the Hack Chat to talk FPGA with us! Al Williams12:04 PMThanks Stephen and thanks everyone for jointing Al Williams12:04 PMjoining rather Stephen Tranovich12:05...
anfractuosity12:19 PMIs the minimum layer height you can achieve dependent on the resin used (i assume different resins may be more sensitive to the UV light?) along with the stepper motor? Andrew Sink12:19 PMAbsolutely! Andrew Sink12:19 PMThat's a great...
