BQ25504 Working Like It Should
Log from Ultra-Low Power LiPo Charger via Energy Harvesting
15 July 2018 First a word about packaging. I designed the BQ25504 breakout board to be as small as possible because I had in mind the idea that it would become part of an integrated (hybrid) power source. That is, the LiPo battery, solar cell, and BQ25504...

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....

Log from Reverse engineering the Rotor
First of all, sorry for the delay. Life's been kinda busy and I didn't make any really interesting progress on the project; still, I think I gathered enough material for an update (at least, now you know I'm still alive!).The phoneAnyway, the first major...

The Case of Cases
Log from D-DAQ
See Update BelowContext being more that of the puzzle of cases not one case "to rule them all," but I digress. The past week I've been going through a few catalogs to find an enclosure for D-DAQ's mainboard. Previously, the PCB's form factor was based...

Umbilical Tower Redesign
Log from Apollo Saturn V and LUT
I love it when I can find parts that someone else designed, it saves me time and effort. Aviator67 produced a treasure trove of add-on parts for the farscape1 LUT. After printing and assembling the Level30 floor framing along with the cable tray template...

Migrating to Platform.io IDE (Atom)
Log from The Smart Letterbox
More structured details to come. Some quick notes:Copy the original Arduino .ino file to Platform.io IDE on Atom may cause build issues. Create a new .ino file using PIO IDE and then copy/paste source code from Arduino .ino file to new .ino file. The...

September 28th 2023: I can't make the linear actuator move precisely
Log from Automatic Moving Cricket Wicket
It was dumb to use a DC motor for this project. I should have just ponied up the resources for a high speed stepper. My plan was to attach a rotary encoder to the DC motor to accurately measure the number of rotations. This is not easy....First, I tried...

Frequencies
Log from Voyage 200 Upgrades
For some reason the 47 pF value for the caps is sitting in my mind. Either after 'calibration' the LC meter is so far off that it read both my TI-89's and my V200's caps 51 pf, both ~8% high, or both of them are within their 10% tolerance and reading...

Log from Portable environmental monitor
Putting everything together also requires checking everything separately first. So I did with the MiCS-VZ-89T sensor, and here is the story, also presented on my blog: MiCS-VZ-89 Air Quality SensorA low power sensor that can measure at the same time...

Z80 (CP/M) Writing to SD Card
Log from 3-Chip Z80 Design
Digging into SD card writes means shifting gears from the Boot BIOS source code since the Boot BIOS code only does reads. The CP/M BIOS code (CBIOS128.LST) which does the reads/writes after booting. Here's the BIOS code for writes to the SD Card: 0754...

Breaking AES using a $90 Development Board + OpenADC
Log from ChipWhisperer®: Security Research
Long ago when I started prototyping ideas, I was using a $89 FPGA Board (Avnet LX9 board). The ChipWhisperer system has always supported this board, but it's not as well documented as my newer, fancier hardware. I wanted to make a log post to demonstrate...
