Get it? Preparing/cooking a pie? Pi?... *ahem*It's pretty obvious that the Raspberry Pi won't fit into the Mac's casing, so I'm going to be trimming it down. If you're interested in learning more about this process, you can look up 'diet pi' (or, of...
I was looking to get a new PC at work. I wanted to try a small PC, like a NUC form factor with standard components. In end of April 2017, I selected a C292-Z270 I7-7700 mini PC from E-ITX: 120W Power AdapterpicoPSU-150-XT Power supplyASRock FATAL1TY...
What IS The Speed of Light Squared?What IS Distance Squared Over Time Squared... ?What is Time Squared?!Dunno, BUT:Well, Acceleration is Distance Over Time Squared...And Distance Squared is AreaSo might Speed Squared be The Acceleration Of Area?..."The...
As I wanted to make my project better and fully comparable to original Odroid Go (OG) a made few more iterations. Because they are not so different from each other, I decide to cover them in one log and describe just changes which differentiate these...
The biggest issue to getting this thing working has been the Electron Beam Gun power supply. This gun wants 10kv at up to 1.2amps to run it, thats 12KW! Not easy to do. I looked at trying to modify other stuff like ion pump power supplies, built voltage...
Small update: now there are two registers working: A and E. Next step: connect the ALU module and perform operations with them. Video: PS.: probabily due to poor quality breadboards, i'm running into problems of bad connections that are driving me crazy......
Nesta última década assistiu-se a uma proliferação enorme de aparelhos eletroeletrônicos portáteis, tais como: brinquedos, jogos, relógios, lanternas, ferramentas elétricas, agendas eletrônicas, “walk-talks”,...
Last year, I made a badge using a 2.13" Pervasive e-paper display:https://github.com/pdp7/kicad-teensy-epaperIt originally used code from Jarek Lupisinki for a Freescale microcontroller (the Teensy) and later Zach Archer wrote the wonderful FancyEPD...
Another video showing some results of my science weeks of this year's HackadayPrize:The resolution of the sensor stripe I used in the video is 42 micrometers, thus we get approximately 580 sensor pulses per Inch at the Arduino. The resolution of the...
It all started from a simple question, Can we have a precise idea of the quality of the air around us ?We started looking for air sensors and found quite a few that were arduino compatible so yes, it was possible. We first wanted to make an all-in-one...
I have been testing my very dumb arduino code for esp8266 written for dual input filament detector (it knows when filament ends on "spool" or when You want change filament). I'm running smoothiware so any changes in the firmware code made by me would...
It has been over a decade since the last time I needed to program a parallel (E)EPROM of any type. Back in those days there was a parallel port on virtually every laptop and desktop computer. I ended up selling my old parallel port programmer years...
