First attempts at understanding how the video link works
Log from Controlling a JJRC H37 Elfie quad from a PC
I haven't done any further tests with the UDP controls, but I captured some more traffic in order to try to figure out how is the video transmitted between the quadcopter and the mobile phone. The communication seems to be established through port 8888...

Gathering information
Log from WD2002SJ Bench Power Supply
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...

Access SD Cards from the PSoC
Log from 3-Chip Z80 Design
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...

ALU and Instruction Set
Log from Novasaur CP/M TTL Retrocomputer
Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...

Comm protocol between camera and drone controller
Log from Reverse Engineering a ProMark VR Toy Drone
Initially I thought the data stream from the camera board to the quadcopter controller was PPM. This signal is only active when the app is running and the on-screen controls are brought up. The quadcopter has to be power-cycled in order to be controlled...

10/8/23 Update
Log from 1802 MemberChip Card
Here are some "Quickstart" instructions for the Menu, BASIC, VTL2, and Visual/02 programs in Mike Riley's alternate program ROM. They're not a full manual yet, but will get you started and give you a "taste" of vintage programs and languages. A Quickstart...

Finally, some publicity!
Log from RasDash
An article recently published on MOONGIFT, a Japanese developer site, has showcased RasDash! The article is entirely in Japanese and Google Translate won't accept the URL as it has special characters but YANDEX does. Below are some links and a basic...

Timing & camera settings

ETTL protocol with the EOS RP & 580 EX II
Log from Wireless ETTL flash conversion
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...

New Boat, New Autopilot - using an old laptop mainboard!
Log from OpenCPN Chart Plotter /w Autopilot and Waypoints
For quite some time I have been thinking about the possibility to using a laptop to run all the heavy OpenPlotter and OpenCPN stuff instead of using a Raspberry Pi. The performance of the RPi is... well it's usable but it's not a pleasant user experience....

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...

3. Fundamentals of Hexapod Robot
Log from Hexapod Modelling, Path Planning and Control
In this chapter, the fundamental concepts of hexapod robots such as walking gaits, stability, kinematics and dynamics are covered which are essential to obtain a better understanding of the control architecture that is delivered in the next chapter....

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....

20230221a -- File Deleting/Erasing
Log from ROM Disassembly - AlphaSmart Pro
Previously, while rummaging for scan codes, I was correlating known behaviour with key codes. One of those keys was the Clear File key (0x56). I forgot to post about that find, but it's still worthwhile to mention the file clearing operation...

In The Digital Domain
Log from Reverse-Engineering the milight on-air protocol
I also wanted to sniff the communication between the micro controller and radio IC, but couldn't get the case of the remote control open. At the next opportunity I brought the Mi-Light Wi-Fi controller with me and got that open more or less easily:Inside...
