About Zeus WPI
Zeus WPI is the student association for Computer Science at Ghent University. Our goal is to provide a stimulating environment for motivated students looking to expand their skills by engaging in interesting real-world projects.
We organize various tech related talks by experts (eg. professors, PhD's, Richard Stallman, Felix Reda, ...), hands-on coding events and introductory lectures for cool technologies. Together we build interesting applications for Ghent University students (Hydra), for FaculteitenKonvent and 12urenloop, and ofcourse for ourselves.
2023-12-06 • Jasper Devreker • Reverse engineering the ESP32 Wi-Fi hardware registers
The ESP32 is a popular microcontroller known in the maker community for its low price (~ €5) and useful features: it has a dual-core CPU, built-in Wi-Fi and Bluetooth connectivity and 520 KB of RAM. It is also used commercially, in devices ranging from smart CO₂-meters to industrial automation controllers. Most of the software development kit that is used to program for the ESP32 is open-source, except notably the wireless bits (Wi-Fi, Bluetooth, low-level RF functions): that functionality i...
2023-12-06 • Jasper Devreker • Reverse engineering the ESP32 Wi-Fi receive registers and showing off a proof-of-concept
This is the second article in a series about reverse engineering the ESP32 Wi-Fi networking stack, with the goal of building our own open-source MAC layer. In the previous article in this series, we built static and dynamic analysis tools for reverse engineering. We also started reverse engineering the transmit path of sending packets, and concluded with a rough roadmap and a call for contributors. In this part, we’ll continue reverse engineering, starting with the ‘receiving packets’ functi...
2023-05-14 • Tom Naessens • Je raadt nooit wie in '23-'24 ons nieuwe bestuur vormt!
Afgelopen dinsdag kwamen we traditiegetrouw samen in de studententuin om ons huidige bestuur te bedanken voor hun inzet en voornamelijk, om een nieuw bestuur te verkiezen voor het komende academiejaar. De verkiezingen waren spannend omdat er voor bijna alle functies meerdere kandidaten waren. Uiteindelijk is iedereen die dinsdag opkwam, verkozen en dus stellen we met trots ons nieuwe bestuur voor dat Zeus WPI volgend jaar zal vertegenwoordigen: Rol Naam ...
2023-02-04 • Jasper Devreker • We bypass read-out protection on the CC2510
One of our members managed to score some e-ink displays from eBay. These displays are used in shops, where they indicate the price of the items that can be bought. This has two key advantages over regular paper price tags: the text on the e-ink displays can be updated automatically and it’s possible to do fancier graphics. e-ink has an important distinction from the more common LCD screens: they only use power when they change their content. This enables the tags to have a small capacity batt...
