EC firmware dumped
Log from Reverse engineering Toshiba R100 BIOS
After another long hiatus, I've come back to this project. Let's break this thing!I've etched a new board that lets me access important pins (serial TX, RX, CLK, BUSY ; RST and power lines) without having to fiddle with the previous hacky breakout board.I've...

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...

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....

Peak Performance
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...

[E2] Initial extruder tests
Log from SecSavr Sublime [gd0036]
So I turned off the minimum extrusion temperature so that I can send over a print without heating up the hotend first. It didn't seem like the extruder wanted to move at the start of the print at all until I tried spreadcycle mode. ...

[E2][M] Tweaks
Log from Tetent TestCut [gd0139]
First up, I want to say that the doorstop Tetrinsic shape unexpectedly helped out in this design. Thumb1 would've instersected Finger2 and Fingers2-4 would've intersected the same fingers on the other side if not for this design: Tetrinsic 2.0 didn't...

[E2][T] Thinner solution idea
Log from Tetrinsic [gd0041]
[19 Dec, 14:00] I'm still trying to mine for a solution and I thought about having multiple concentric belt rings instead of 1 solid belt. It turns out that square cross-sectional belt exists and in a variety of lengths: Thus I started to plan...

[E2][R] PCBWay still can't manufacture?
Log from Coaxial8or [gd0144]
[07:00] I wake up and I get this: From PCBWay: Sorry, our factory does not have a suitable cutting tool for processing your parts. You have two options: 1. If the internal groove is not useful, we suggest you remove it. 2. Increase the size of the...

Digital Pot Shots
Log from SpiroBoard Aeroponics pH / EC / Motor Controller
As you can see below, I am breadboarding the new peak detector changes before committing to a new PC board. One of the changes involves using a MAX5387 digital potentiometer to control the square wave amplitude and EC amplifier gain. The...

HACKLET 94 – PI ZERO CONTEST ENTRIES
Log from Hackaday.io Project
Hackaday and Adafruit have joined forces to present the Raspberry Pi Zero Contest. A great contest is nothing without entries though. This is where the Hackaday.io community is proving once again that they’re the best in the world. The contest is less...

Starting the 16x16 Matrix (20" x 20")
Log from IoT Matrix Word Clock
I made a cardboard cutout of a 20"x20" square. I then printed my letter matrix to scale (6 sheets of 8.5" x 11"), combined with tape, and trimmed to fit. I then drilled a hole at each letter in the matrix (256) in a rough location. The hole is sized...

Soldering perfboard
Log from Earth Lander 84
I took a perfboard and soldered up power and the data/address busses of the MCU, SRAM, NVRAM and the address bus latch.I did't really care about the exact order of the bits when wiring them up, I just went for the easiest layout. I'm not really sure...

Part 20 - Patrick Van Oosterwijck
Log from A sci-fi adventure by hackaday.io
Lee awkwardly brought himself to a halt in front of the door to captain Myles’ quarters. He wondered how long it would be before he would become just the slightest bit more graceful in low gravity. Straightening himself, he took a deep breath and pushed...

simple thing that can speed up any ili9341 display in my case additional 20%
Log from spi write up to 64 colors at a time on Arduino!
Since i have been getting the ili9341 display ready for fast 32x32 (and 64x64, 128x128) subsampling of amg8833 sensor the ili9341 display has 4 times as many pixels as the st7735 display i have working at fast speeds. to increase performance i am doing...

1K Challange Laser
Log from 1K Challange Laser
At this point, we decided to abandon the concept of mirroring. If we had had a much more complex design with many more points and more than 1kb, mirroring would have saved us space. Due to having so little space however, the algorithms power wasn't able...
