8-24-20: Wobbly
Log from Harmonic Gear Driven Star Tracker
After some more testing of long exposures ive found that the wobble is nearly repeatable throughout all photos, it always makes a U or V shape. I took a time-lapse of the tracker at 5s intervals and found that the output does in fact wobble. Now working...

Log from Caption CERN Contest
Week 20: 6/17/2015 - 9pm PDT 6/24/2015Anyone who's worked on a major project, be it professional, personal, or for a contest like The Hackaday Prize, knows about marathon sessions. Those times when you put in your all and just push the project ahead...

C-ving
Log from PEAC Pisano with End-Around Carry algorithm
OK I thought that the amount of data in the future would be too large and I decided to do the sieving in C. Using the available scanning data, I could only go up to 2161 : n1=46 and n2=2114.The first hicup comes at 1511 so there is no point in dealing...

Encryption Encryption Encryption
Log from WiiChuck
Looking at the registers I noticed something. the first 24 bytes look like they have data and the last 6 bytes look like they have data. This looks like what a WII peripheral in encrypted mode would look like. The fixed 8 byte pattern repeating every...

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...

Rewrite code with FastLED + Gamma Correction
Log from SkyLight
Today, i rewrite a code of ambient light of arduino module applied FastLED library carefully. Why? there are 3 important thing, 1) the legacy code of adalight is based on SPI that is used by a RF module too. I think move pin in code of adalight from...

Mass production
Log from Ph0xx
For those wondering how we assembled the boards, we compiled a video of all the different steps. We started off with prototype machinery (Mechatronika M10 and Mechatronika MX70), manual solder paste dispensing using a eC-Stencil-Mate and reflowing...

Audio input for 20 cents USD
Log from 1 dollar TinyML
TLDR: Using analog MEMS microphone with an analog opamp amplifier, it is possible to add audio processing to our sensor.The added BOM cost for audio input is estimated to be 20 cents USD.A two-stage amplifier with software selectable high/low gain is...

SATA, DDR3, Verilog Visualizer and Other Stuff
Log from Nysa: FPGA Development Environment
SATA StatusAfter weeks of painful debugging. I have been able to read and write to the hard drive!I ran into an issue though... the speed at which I can communicate with my FPGA to/from my computer maxes out at about 16MBs and the hard drive reads/writes...

Theoretical background of the Linear FCDT
Log from A new high accuracy tilt sensor
The Linear FCDT has three coils, which take place next to each other. The primary coil is usually excited with a frequency of 1 to 20 kHz and an excitation voltage range of 1 to 24 V rms.The cell surrounded by the three coils is exactly half-filled with...

Speeding up by 20%, profitability almost reached
Log from Bitcoin mining on a C64
Computing SHA256 is a challenge for 6502 CPU inside C64. The main problem is that this 8-bit CPU has only three 8-bit registers while 32-bit arithmetic is required. You need at least 4 instructions (one for every byte) for each 32-bit operation. In practice...

HACKLET 99 – SOLDERING TOOLS
Log from Hackaday.io Project
If there is one tool every hardware hacker needs, it’s a good soldering setup. Soldering irons, heat guns, reflow ovens and the like make up the tools of the trade for building electronic circuits. Spend enough time working with a tool, and you’ll find...
