Using a Raspberry Pi as a remote access device for sysadmin or pentesting purposes is a fairly popular concept. Kali 2020.4 made some significant changes to the distro that seems to break a great deal of the content on the web about setting up a reverse shell. After recently upgrading my Kali box, my remote…

Digging on Xojo. It took me less than an hour to whip together a crude prototype that let me achieve four goals: Pick an Arduino (or any serial device) from a list of COM ports. Connect/disconnect on the fly. Read data from the analog pins on the Arduino. Send commands to toggle the LEDs. Save…

So a lot has changed since I last fired up my HackRF. GNURadio hit version 3.8, so did Python. GNURadio deprecated WX GUI and moved to QT GUI elements. My two go-to test flow graphs didn’t work anymore on my Windows 10 machine. So here is what I changed: FM Radio Receiver In the osmocom…

I am starting to tinker with the GreatFET as a possible candidate to be included in my toolbox of embedded development tools. I2C is a protocol I spend a lot of time messing around with, so that provided a good test case for trying out the GreatFET in a real-world situation. As of the GreatFET’s…

Another day (of quarantine), another project. Today explore the latest version of the Arduino IoT Cloud (beta). For the hardware we have the following: MKR 1010 MKR ENV Shield ST LPS22HB : atmospheric pressure ST HTS221 : temperature and humidity VISHAY TEMT6000 : Lux of the ambient. VISHAY VEML6075 : UltraViolet wavelengths A / B…

One of the silver linings of coronavirus quarantine has been time to tinker with development boards long ago acquired yet rarely tinkered with. Such is NodeMCU. I am interested in self-contained devices that rely on little support infrastructure yet offer lots of functionality. So one project I have tackled was the ability to remotely and…

One of the challenging head-scratchers I came up against in learning embedded electronics was analyzing communications that utilized the I2C protocol. One challenge was realizing there was 7-bit and 8-bit address implementations. Not realizing this made for a very long debugging session. It was one those sessions where everything was working, but from my analysis,…
