The (few) shortcomings of CueTools
Log from Music CD Ripper Robot
CueTools.ConsoleRipper isn't perfect - It does a database lookup and, if included in the Online database, tries to write a WAV and CUE file with illegal file characters, eg. Question marks, colons, slashes. It even found a funny character with three...

Boostrapping Lights and Sensors
Log from Bullet Movies
So, part of this project will involve creating very fast light pulses (the photo-flashes), and part will be detecting fast optical pulses (the milk drop and bullet detecting photo-gates). The two, of course, are related in that a fast optical pulse generator...

Step 3 - IMU and BLE functions
Log from Personal Guardian
IMU functions The Arduino 101 Inertial Measurement Unit is fully documented and works well. For the fall detection, the software detects a short period of freefall followed by a shock. Both events are handled via callbacks: void imuInit(void) {...

Interfacing ternary and binary components
Log from Homebrew ternary computer
Ok, now it is kind of proven that binary CPLD (or FPGA) may implement ternary logic, but how we can integrate it with "true" ternary components, especially when CPLD is 3.3V and TRIMUXes are -5V and +5V? Answer is DG403 chips may do the job: Because...

Characterizing the Buck Converter
Log from Solar MPPT Charger for 24/7 "IOT" devices
First up, the latest revision. Small changes from the last version including tightening up various current loops in the buck converter and moving the battery-side transient TVS diode to the anode side of the reverse-polarity protection diode to...

Extracting and purifying PHAs using mealworms
Log from Plastic-producing personal bioreactor system
In the first log I investigated the methods of growing bacteria, and extracting ,then purifying their PHA granules into usable plastics! A major roadblock is the usage of toxic solvents in the extraction and/or purification process. This means...

Joules to photons. Finally.
Log from Coin Cell Challenge...
Ok, sorry about the clickbait title; who can resist the promise of LEDs? I promise a photo of a lit LED in this log, so you don't go home empty handed. This log is a quick one to introduce an intriguing potential alternative to coin cells. I have...

Please, GCC !
Log from PEAC Pisano with End-Around Carry algorithm
I get tired of fighting GCC's weird code generator that won't get a clue from my source code. I'm (still) using gcc6.4.1 (2017, I know) but I don't know how to make it understand basic things... This is critical at my level because any little performance...

Conquering Clocks and Gremlins
Log from Dreamdrive64
PSRAM Challenges The PSRAM presented numerous challenges throughout development. One issue arose from the SSI clock divider, which could only be set to even integers. When the RP2040s were originally clocked at 266MHz to meet N64 SRAM timings and the...

Scientific papers on tree tomography, Part 2
Log from Exploring the internals of trees with sound
First paper: Elastic wave modes for the assessment of structural timber: Ultrasonic echo for building elements and guided waves for pole and pile structures (DOI: https://doi.org/10.1007/s13349-014-0087-2, though that goes to a paywalled copy) by Martin...

FarmBot Genesis V3
Log from FarmBot - Open-Source CNC Farming
FarmBot Genesis V3 exhibits the following changes from Genesis V2: Updated bracket design to minimize the number screws needed, making assembly easier and faster and decreasing the number of partsSimplified cross-slide design combining 3 plates into...

Papers, Please.
Log from Bench Top 5-Axis Mill
I'm in the middle of a literature review in an effort to do two things. One, I'm looking to see what has been done before, and two, I'm attempting to sort out the math involved with designing machine tools well. Below I've the bibliographic entries for...

Counter implementation
Log from VHDL training board
I know lots of hackaday readers are HDL specialist and this content may not be useful, but beginner (including me) needs some struggle just for simple application. Here I would introduce "how to make simple counter" using my training board.The training...

The actual informations
Log from Extension card for TDS3000 scopes
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....

Choosing the UV LEDs
Log from UVA
LEDs come in all manners of sizes, colors and brightness. To be able to choose the most appropriate ones, we need to know what are they going to be used for. For this purpose, we did some market research on UV curing glues. After checking the datasheets...
