At work I needed to precisely measure the vibration frequencies of a device. I pulled out a M5StickC that I had laying about and wrote some custom code for it. This is a small ESP32 based micro controller with a built in LED...
Here's the second major routine needed to make working with decimal numerical input possible.Get_Number parses through the text input buffer looking for numerical ascii codes that fall in the range 0x30 to 0x39. These correspond to the digits...
Most CPUs contain some number of internal registers, a subset of which are available for programs to use. These are often not much more than very fast internal memory connected to internal bus(es) and ALU(s), meaning that the the transformation of bits...
Earlier this year.. The CNC mechanics of #Minamil: a minimal CNC mill had been working encouragingly well for a while but depended on a bunch of other stuff that could be integrated into a compact enclosure but wasn't. A few months ago...
This log entry describes a completely new enclosure that I kind of accidentally built in the middle of getting this 3d printed re-do of the CNC mechanics to work well enough to believe that it would actually work. I've copied it here from #"Desk Accessory"...
The log An even better ALU touched a few interesting things but has one fatal flaw : the XOR operation needs the NEGated operand SND, because it is also used by the final stage of the adder! The self-tests don't pass and I now remember why. The optimisation...
The flip-dot infection has spread and there is no cure so let's go with it.The Tetris game is a pretty cool application but then, @menguinponkey started #Game of Life on DIY TTL CPU 'S.A.M.I.R.A.' and... Do I need to explain in details ?OK I will :-)Conway's...
7/08/2018 Now that everything works, I am in the process of refining the design to optimize utility. I got the latest iteration (v.02b) back from OSH Park and built one. Here ready for testing. A closeup view. I added 2.54-mm diameter mounting holes...
I am back! Yes, it has been a while. I have been travelling for a conference and I have been preparing my presentation, some paperwork and finishing other projects. It was amazing!! Coming back to the main subject, I know I did not explain much...
Odroid-U2 doesn't have a Power button, so I made one without modifying the board.And excuse my English.Whole setup requires more power than Odroid can provide from USB ports. I assumed the following:-Odroid- 5V 2A (2x 500mA for USB ports included)-DVD...
Now that the breadboard prototype appears to be working, it's time to make a more permanent (and smaller) version. With a few minutes of googling, I found a website called EasyEDA, that allows you to design PCBs using their online tool. It was fairly...
From the Project Description: "There is some debate about the use of multiple parallel capacitors of different values in filters. The parasitic inductance of capacitors mean that large capacitors that are capable of supplying the instantaneous current...
3.1) VinyGo controller 3.1.1) FS1.1: Power supply The power function allows us to create: +12v, +5V, +3.3V, 0V. Input(s): L0: AC-DC power supply 12v 3a Output(s): +12v, +5V, +3.3V, GND 3.1.2) FS1.2: LCD touch screen Display digital information...
After creating a proof-of-concept with an ADXL337 from Sparkfun and some conditioning with a breadboard, which was super noisy, I went about putting together a schematic for a small PCB. I ended up choosing a FXLN8361Q from Freescale (NXP). Compared...
