The STM32 board was just a hair bigger than the PIC, but the biggest pieces are still the power switch, channel button, & battery. The plan is just to print an L enclosure which scotch tapes around the hot shoe & sticks up. The antenna will...
After a fresh installation of Debian on my Beaglebone Black I was greeted with a console interface that had all the essential tools already installed. It's a development platform after all. They provide everything for I2C devices as well. I had a 24C02...
Back to the workshop for the revenge of the return of the son of the Vintage Ring Oscillator ! This time with a new ally : the ceramic capacitor ! TL;DR : it's 60% faster ! But the V/F curve might look different from @Tim 's experiments... As usual,...
This is an overview of the layout in which KGE works. Get User String (Round 0)Split String Into PairsIf Not Enough Then Add Specially Made Character Which Is Deleted During DecryptionUse Byte SubstitutionSwitch User Strings To IDs and Find Replacement...
Well, I did it. I ordered my first custom circuit boards. I laid out a prototyping board with an ISA bus card edge, sent it to dirtypcbs, and after a month of impatiently checking the mailbox, they arrived. I ended up with eleven boards. After I've built...
At the Sydney 2018 linux.conf.au, Paul Schulz will be giving a presentation about the Cosmic Array and software development. Paul, has been a key person in development of the sound and wireless networking aspect of the Cosmic Array....
I've managed to pull down data samples, label and sort the data and upload that data to an s3 bucket. Once the data has been made available we need to generated the mel-spectrograms, to do this we'll be using librosa to make the spectrogram and saving...
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
Tonight I gathered some reference/research material for this project. Fortunately, several others have done some really great work with this module, so here's credit to them: LTC3780 DatasheetBeyond Logic blog postTemplaro blog postGreat Scott videoJulien...
Yesterday before sleep I replace LD271 IR LED and this morning oficially started data gathering.On the pic you can see my morning glucosis test. Unfortunately the hour is wrong, need to fix it.What I found strange is the variation of measurements in...
Here's the tracking performance over 93 hours. The graphs demonstrate both the frequency drift over temperature and the much more gradual drift from aging. The enclosure appears to sufficiently blunt the cyclic temperature changes, and the...
After my frustration with Vivado, I've done a discrete logic implementation of the "MVP".A hub with 4 connections, with 4 switches, so it's essentially 2 inputs and 2 outputs. Each input can be switched to any one output, no output, or both outputs....
For checking the MT9D111 two wire interface I started wiring the camera module to an Arduino Nano. Then, I programmed the Arduino based on the 16 Bit Register Read and Write Examples in page 9 to 11 of the Developer Guide. Wiring:MT9D111 ------ ArduinoGND...
I got stuck in trying to debug what went wrong in the Fuzix boot.To combat that frustration I've been working on learning Kicad 6 properly, while also trying to design a PZ1 PCB around the Raspberry Pi Pico instead of the Teensy.The Pico is really cheap...
