Multi-Slave Write Access Demo
Log from InterNoC
After a few weeks of days of debugging and a few weeks of life getting in the way a first real-case scenario demo of the InterNoC functionality is presented here... Setup This log presents a demo of the InterNoC hardware design (see Fig. 1) implemented...

Identifying the components
Log from Repurposing an old nixie thermometer
So, time to identify what I have to work with. First the nixies. I had forgotten but there are only 5 numeric nixies, the rightmost 5, which are type ZM1000. The leftmost nixie is a symbol nixie ZM1001 which can display X, Y, Z, +, - and the sine wave...

James Aguirre12:17 PM@0xCoto that's great stuff! Canadian Centre for Experimental Radio Astronomy12:17 PM@Dan Twedt my first paper on SDR radio astronomy was about SETI back in 2004. Dan Twedt12:18 PMThat's awesome! A good magnet to the hobby! 0xCoto12:18...

Exit MIG, Enter LiteDRAM.
Log from BoxLambda
LiteDRAM in the BoxLambda Architecture. Initially, the plan was to use Xilinx’s MIG (Memory Interface Generator) to generate a DDR Memory Controller for Boxlambda. At the time, that was (and maybe still is) the consensus online when I was looking for...

Generalised fault injection
Log from VHDL library for gate-level verification
Christos has modified the original DFF gates to inject faults and evaluate/validate the fault-tolerant memory cells used by the CERN. Meanwhile, I created this library to help with ASIC design, which is a different beast and methodology. I have no bit-flip...

Log from Keeping Ham Radio Relevant Hack Chat
KI6NAZ Josh12:14 PM@Martin Mortensen There are many texting type of modes in ham radio, both VHF/UHF like we get access as technicians and HF where we can make longer distances contacts. One that comes to mind is APRS. Which can send multiple types...

Learning FPGA And Verilog-Beginner’s Guide Part 1
Details from Learning FPGA And Verilog-Beginner’s Guide Part 1
Mimas A7 - Artix 7 FPGA Development Board Introduction Learning electronics can be a bit challenging sometimes, but it is really fun if you have a little patience to read, understand and experiment. FPGAs need not be any different. Let us give it a...

Acquire a USB amplifier/ADC sound interface
Instructions from Nuclear Magnetic Resonance for Everyone
This example uses a Behringer U-PHORIA UMC202HD for the NMR receiver system, it provides a very low noise amplifier, and a 192kHz 24-bit ADC, powered by 5V USB. It is widely available for around $100 USD. The similarly priced Native Instruments...

Satellite CyberSecurity / POC Rouge Ground Station (Recon Only Unless Permission Given)
Log from Cyberdeck for 2024 Challenge
So my cyber deck can or will take the form of three different sizes it depends on how I end up actually choosing to make it more or less portable if I make it in the larger one it would have potentially room to carry all the antennas and stuff but that...

Receive signal from our transmitter
Instructions from FPGA Frankenstein as CW Transmitter
Unfortunately, we cannot use a standard radio receiver to receive our transmitter. First, because of the frequency bands-the frequency of the transmitter is outside the known broadcast bands. Second, because of the type of modulation used. The...

Digital Transistors
Log from Evaluating Transistors for Bipolar Logic (RTL)
Digital transistors look extremely appealing to build discrete logic: They come with integrated resistors so the bias emitter in an RTL gate can be omitted. Furthermore, they are available from many manufacturers in basically any package type, down to...

CSTroN – Monitor powered by an ancient CSTN screen
Log from CSTroN - CSTN LCD monitor
Introduction Back in the last century, when the CRT was still the most common technology for computer monitors. It was quite common to see such an argument: the LCD will probably evolve and produce better images, but it is never going to replace the...

Generalised fault injection - part deux
Log from VHDL library for gate-level verification
The idea progresses while I gather the necessary ingredients for the new version of the library. At this moment I consider getting rid of all the C and VHPI code because VHDL already contains all the required features, I think. Let's start with the fundamental...
