[Checksum] XOR

Rekent een XOR checksum uit in c++ (bijv voor Arduino). Je kunt het gebruiken om ofwel een zin te decoderen of hem aan je zin toe te voegen. Deze zelfde checksum is gebruikt in...

[2D] Largest Area

This function for Matlab gets all the largest areas from a binary image, larger than a given threshold as a factor [0-1] of the largest found area. function [outim] = largestarea(im,threshold)% Tim Zaman ©...

[3D] Ransac (get planes from point clouds)

[3D] Ransac (get planes from point clouds)

With this code in Matlab you can get planes or surfaces from point clouds (points in space). It uses the RANSAC algorithm and a LSQ function in the bottom. I have made two alrogithms,...

[2D] Reflectance Image Quality Checker

Today I finished the Release Candidate (RC) of the Reflectance Image Quality Checker software. This piece of software allows you to upload an image (.jpg, .tif, whatever) into the website. The website analyses the image through Matlab in...

[GPS] + GPRS to FTP to website

I decided to make the “Sherlock I” which essentially is a GPS monitor that parses the info via GPRS to an FTP server, which converts it to a website with a simple PHP script...

[Flightcomputer] HoHoHo 1

This was the flightcomputer (Arduino C++ based) used for This Project. It gets serial data from TWO GPS devices, the atmel processor of the arduino parses it to a NTX2 443mhz radio output, and...

[SMS] Sony Ericsson PDU

For nothing have I had more requests than this piece of code. It’s use is obvious; forcing a turned on Sony Ericsson that supports a real serial interface to send a sms, receive, read,...

[Flightcomputer] HoHoHo 3

This is the flightcomputer for the infamous HoHoHo3 high altitude balloon flight. It uses GPS serial data from a GPS receiver, strips it and parses it to a NTX2 433mhz radio transmitter. Also, it...

[Radio] Baudot

Deze code in C++ laat je radiosignalen uitzenden in baudot (rtty), ik heb dit gebruikt voor mijn ballon-project met een arduino controller. De gewoonlijke ASCII code is in 8 bit; dat betekent 8 ‘beeps’...

[Radio] Hellschreiber with Arduino

This code in C++ produces a radio Hellschreiber output, with characters as input. The characters are (in this code) static, but it is easy to make it dynamic. The code is rough since it...
