NeuroBytes v0.92 Prototype
Log from NeuroBytes
Today, the NeuroBytes project takes its first baby step into the 21st century.Okay, ignore the extremely sketchy construction techniques. It's an STM32F0 Discovery board, chosen due to its extremely low cost (under $10) and built-in ST-LINK programmer....

Video added
Log from "Connect" to an atomic clock in space! GPS, DCF77
I have updated the detailed description with a video about the menu. Further videos and design description will come.

DCF77 signal reception video added - must see!
Log from "Connect" to an atomic clock in space! GPS, DCF77
On the video below You can see on the oscilloscope how the DCF77 signal waveform looks like. You can also see how the two separate clocks are snychronizing to the DCF77 signal.

The Hackaday Prize: stage 2 video released
Log from "Connect" to an atomic clock in space! GPS, DCF77
I have finished the stage 2 video for the Hackaday Prize. It is an overview about the current status and main operation of the clock.

Want to Hack the Hackaday Prize?
Log from Analyzing the Hackaday Prize 2015
Update: I added that stubborn LibreOffice pie chart at the end ;)What does it take to be a winner? Getting an entry in early sure helps.I think projects with pictures, videos, and clear details, look like they get more attention.Here is the competition,...

A Better Sheet
Log from Analyzing the Hackaday Prize 2015
A new and improved spreadsheet is now sorted by project, instead of by contest, making it easier to sort and analyze (no more double entries!) Get the spreadsheet, it looks much better. Download the new one here. It has presorted sheets for most Skulls,...

Artist's impression of finished product
Log from A Versatile Labtool
So far I've designed a 3D enclosure using SolidWorks. The bottom will be 3D printed for now, and any errors can be rectified before going for an injection mould. The top plate will be laser cut and engraved in translucent acrylic, and added .Figure:3D...

Failure? Yes, that's still an option
Log from BorgCube ROV
After a month away, finally got the ROV back in the tub today.First, the good news. The new tubes sizes and arrangements means the ROV is much less buoyant than before. I was able to remove all the extra lead weight which still left the ROV slightly...

UART protocol cracked!
Log from Model S BMS hacking
As I found in the last post, the isolated UART bus daisychained through the Tesla modules is running at an odd frequency, 612,500bps. This is problematic as it is not a standard PC baud rate. I had an FTDI board lying around so I had a peek at the datasheet...

Prototype time
Log from Shakelet - alerts for the hard of hearing
Since receiving my first PCBs there has been a flurry of activity. Naturally, the first thing I did was to solder one up:Having never used SMD components before I was pretty pleased with the results. For the moment I am attaching the Piezo sensor with...

Hammer Design
Log from hit'em!
The hammer is assembled from 4 main parts: The hammer head.The PCB assemblyEnd pads (x2)HandleThe hammer head is 3D printed. It's designed as a hollow, T-shaped cylinder with rails that hold the PCB and the pads in place. It was printed from transparent...

Design and testing of the PAR sensor
Log from PULSE : Profiling Underwater Light SEnsor
The most important component of the profiler is the PAR sensor which is using to measure downwelling irradiance at the surface and through the water column. In order to measure downwelling irradiance the sensor must measure light across the entire upward...

Solving the Math: Computing the Servo Angles
Log from AutoFan - Automated Control of Air Flow
After the pixel position and size of a face in the camera image has been detected, the horizontal and vertical servo motor angles can be computed in order to point the air flow into the direction of the face. The geometric relationships between the camera...

How Do You Calculate The FWHM of the Instrument Profile?
Log from DAV5 V3.01 Raman Spectrometer
Below is a comparison between a laser scan today (12/26/2016,) and one done on 9/28/2016DAV5 V3 spectrometer; DVD diffraction grating-2770 gr/mm { 1 x 0.19 x 2770 = 5263}{531.94/5263 =0.10}Resolution profile (present) = 0.10nm With a slit width of; 120umWhat...

How goes it up to now
Log from Hoarders Active Load
OK, so I've start this project before submitting it. Best bring it up to date...Firstly I got myself a beefy heatsink (one that was supplied with an AMD Phenom2 I bought ages ago) that would fit into the enclosure and drilled and tapped 2 holes for 2x...
