Generating prior art with patents
Log from prism laser scanner
Prior art is of huge importance to the open-hardware movement. It prevents that certain markets become locked for 20 years by patent law. Let's generate some prior art with patents. I claim all the claims generated by rewriting all patents in the world...

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...

Fibonnaci checks out
Log from GTXL Gigatron clone computer with keyboard
Well, I should have expected the Fibonacci code to work since I already checked out all the previous functions of it. So I'm wondering what isn't going to be working to prevent the ROM code from working. I'm running the ROM v3 code because...

Hardware Mock-up Programmed
Log from Terminal-BASIC programmable calculator
I have continued debugging the hardware mock-up. The fundamental target was to program a simple RPN calculator UI with 6 operations plus a number of scientific functions. The integration with BASIC will come later, after all the hardware components are...

Up to date
Log from Gigatron Forth
[This post brings me up to date with the work I've done so far, and corresponds to the state in commit 0e4b928083ae69bb6ae577197ac016e93a77e80e] I've documented my design for the NEXT routines, which I've committed to Github here. It's a little sketchy,...

Nonlinear response to improve usability
Log from Stingray
I should apply a gamma curve to the analog axes read from Classic controller to make the response of the stick more subtle near the center and more steep close to the edges. Classic controller analog sticks provide position information with...

Version 1 Testing
Log from Ultra Low Power Feather Development Board
Version 1 of the hardware arrived, and I have been testing it. Almost immediately, I discovered I had made a connection mistake on the 3.3V regulator, and the system would not run normally from battery power. I desoldered that part, and by providing...

Running a task at max priority
Log from Bare metal second core on ESP32
MethodThe idea is simple, just build the SDK in normal Dual Core configuration, but pin all tasks to the first core. We then can run a task on the second core which should (in theory) run uninterrupted by everything.But: We can't be sure nothing is running...

Tighter C-ving
Log from PEAC Pisano with End-Around Carry algorithm
lBefore I can get my hands on more numbers from the scan, let's go back to 147. C-ving. For the prime 1511 and higher, there is not enough data to get a complete histogram and there are histograms with 3 holes. We already know that the holes are symmetric...

ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

AES-256 Is Not Enough: Breaking a Bootloader
Log from ChipWhisperer®: Security Research
I'd been pushing hard trying to get a demo of how you can break an AES-256 bootloader. This type of bootloader is often used in products for protecting firmware updates and a good demonstration of why you should care about side channel attacks as an...

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) {...

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...
