I added the Tindie logo
Log from Hackable Electronics Badge Alternate Logos
At the OHSummit, I was joined by Amber Cunningham, community manager of Tindie. While Hackaday and Tindie have the same overlords ruling over them, we can't really have Amber going around with a Hackaday logo on her badge, can we?...So I spent 15 minutes...

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....

All boards received
Log from NEDONAND homebrew computer
The rest of the boards just came:I think I will connect them together through wire-wrapped "motherboard" (lets call it "NEDONAND-10" ; )All of these NEDONAND components could be tested one by one using PIC microcontroller (connected to PC through RS-232)...

Different SD card MBR formats
Log from OSI SD Card Operating System (OSISDOS)
I tried a couple of other cards and found that they have different MBR formats with no header. I noted this in a previous log. There's an offset at 0x01BE that points to the MBR. My theory is this is true for "bigger" cards. I think the reason I could...

20230216a -- RAM signature stamping
Log from ROM Disassembly - AlphaSmart Pro
Revisiting the RAM signature stamping knowing what I know now, I can better see what's going on and record that knowledge. The RAM stamping routine now looks like this:F723 ; stamp 'ram valid signature' on RAM page 0 and 3 F723 stampRAMsignature_F723:...

Building an EC sensor.
Log from Autodro
The end goal for the Autodro is a complete monitoring system for under $10. This means that cheaper, simpler, less accurate sensors are needed. I've started with a simple EC sensor, and am hoping to design something around $1.So far, I've created a sensor...

Three Dollar EC - PPM Meter [Arduino]
Log from Hacking the way to growing food
This Blog will Cover How to build a cheap EC meter for your aquaponics/Hydroponics or water quality related projects. We are not going to get into what the ideal value of PPM or EC is, Just cover how to measure and quantify a fluid.We will be using this...

Starting with the ESP8266
Log from Wireless remote LCD
This is a big question, where to start with the ESP8266. There is the official SDK path, for the brave. There is the Arduino, Espruino... Well, I tried NodeMCU. Starting with this page https://nodemcu.readthedocs.io/en/master/, there is a lot explained...

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...

ACPI is working now
Log from Porting coreboot to HP Elitebooks
At last, I found a bit in EC RAM that is used to enable EC ACPI, so ACPI is working now. I copied the ASL code from vendor DSDT, and now battery, AC, and lid status change can be detected by OS now.https://review.coreboot.org/#/c/19072/

The bugs
Log from Semyon
One thing I've learned from this project is that programming in C keeps the programmer from lots of trouble - it generates the tedious parts of the assembly for you such as switchcase implementations, it assigns variable addresses for you, makes wise...

Running short fragment of program - but needs a lot of fixing!
Log from Let's experiment: NEC V20 + FPGA
I have squeezed some simple instructions into a 16-byte ROM that writes 0x04 into the I/O address 0x00, and repeats (http://www.homebrew8088.com/):A: MOV AL, 04 OUT 00, AL JMP AThis is then converted into machine code (https://defuse.ca/online-x86-assembler.htm),...

EC or not EC: that is the question
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
For some reason, EC probes are relatively expensive. In most cases they are more expensive than pH probes, which to me seem a lot harder to make. So, I decided to make my own EC probe, as you can see below:The contacts are gold plated Studex ear piercing...

What shall we wrap it all up in?
Log from Commercial home automation
Any enclosure needs to be easy to access yet provide enough space to get all of our cables in and out without being too big. A tough challenge!---------- more ----------Once our technology solution is chosen, we have to mount it, cable it, make it all...

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...
