I've been recently looking for a cheap supply of USB and SD card mounts/connectors to bring the costs of the board down (some SD card mounts from other manufacturers are a few dollars each even in large quantities). I found what seems to be a decent...
In lookng at other developing region projects I ran across the R.A.C.H.E.L. (Remote Area Community Hotspots for Education and Learning) project. https://www.raspberrypi.org/blog/rachel-pi-delivering-education-worldwide/ Essentially they distribute Raspberry...
I am going to write a more substantive log soon, but here, see my testing of Deiter's MT15 logic gates:Video of operation: https://impenetrable.fortress.promo/media/8f4289ee07d7cef0ca89c0265f8393fe93f9aa338107f0fb6fd163afc6279ce0.mp4?name=Husky_1585187742736_MOJXH7018J.mp4...
After assembling the hardware, it's time to get the firmware and configuration in place. Initial install of sketch is via USB upload from Arduino IDE:Plug the USB cable in, look on Arduino IDE for which port has been assigned (under Tools -> Port)...
Got some build pics to share! PCBway ( www pcbway.com ) wanted to make sure that they'd stuck all the polarised parts on the right way around as standards and silk screens vary. Good news is they got it spot on! Now to wait for the rest to be populated....
I just thought about turning a rubik cube into an interface or lock by using 6 encoders as a way to grab the rotation and send those inputs to an rgb 3x3x3 cube or 8x8x8 rgb locomatrix, when ready ;) I'm still sidetracked by my continuum quantum device...
We are using lots of different components. Some are open source and some are not. We are also fortunate to be working with some things that only a hand full of people in the world have. We will try to post reference links from all the...
We have one last software that we would like to add to our server. We have now completed a LAMP server with Seafile personal cloud service but there is one more piece I would like to add to make for a robust development server. We are going to add an...
August 12, 2015: I discovered something interesting on the original antenna design today. I had copied the antenna design from a TI reference design without really thinking about it. When I would use the prototype with this antenna design, the range...
Using Circuits.CC engine I created an interactive web site TERNARO.COM where you can play with different switches of TERNARO configurable logic block (by mouse) and see how they are translated into bitstream (at the bottom) and how equivalent circuit...

Testing Propagation DelayI have previously mentioned propagation delay tests using a 5 stage ring oscillator.So what is that?A 5 stage ring oscillator (web.mit.edu):Here is my implementation:Note: I have not made provision for speed up capacitors in...
The web page is split into three parts: A title bar displaying the makerspace logo; a web cam stream and a control panel. To make the webpage quickly I've used frames, so it may not look too good on all browsers etc. The logo image and index.html need...
Got the new boards back from Advanced Circuits (they rock BTW...attention to detail like few others) and they look awesome. Went with black soldermask this time around and it makes things look so much cooler (much more Hackaday-chic). These...
