I became really interested in the capabilities of the nRF24L01 radio modules due to their insanely low price ~$2 in quantity, compared to something like a LoRa module ~$25. So you can basically have 10 for the price of one. Now I am not saying these are comparable devices, since the LoRa devices can be… Continue reading Measuring the Range of nRF24L01 Modules with CircuitPython
Since I started working from home I have been thankful to have a Breville espresso machine that has kept me caffeinated through tough problems and tight deadlines. This machine is a combo espresso machine and grinder. This is nice because it's compact but does come with some tradeoffs mainly on the grinder side. It only… Continue reading Improving the Eureka Mignon Grinder with 3D Printed Accessories
The SQRL Acorn is an M.2 form factor FPGA accelerator card originally designed for cryptocurrency mining acceleration. But due to poor performance and little support, it failed, causing a big scandal. Fortunately for us that know how to use FPGAs, we can re-purpose the hardware to do other kinds of acceleration, such as DSP processing.… Continue reading LiteX on the SQRL Acorn FPGA
The idea behind the Helium project really struck me as a unique intersection of radios, decentralization, and cryptocurrency. And as The Peoples Network keeps growing I saw a need to somehow quantify how well your hotspot is doing at its current position compared to the other hotspots around you. This is because the amount of… Continue reading Helium Hotspot Performance Analysis With Hotspots Health

As part of the GNURadio Conference 2021, the Radio Resilience Competition created a custom competition just for the conference. This is similar to the Capture the Flag (CTF) that has been a mainstay of the GRCon. The cool thing about this competition is that it was not just for bragging rites but real prizes! The… Continue reading Radio Resilience Competition at GRCon21
It's that time of year again! the GNURadio Conference is back, in-person and virtual as a hybrid conference this year! This conference is centered around the GNURadio software and its different aspects and community. Focusing on software-defined radio processing and its applications. Each year the conference is held at a different location in the US,… Continue reading GNURadio GRCon 2021
Ignoring whether NFTs or Non-Fungible Tokens are useful or valuable it is an emerging market that combines art and code so why not try making your own with python. The process of creating an NFT will not be done in python only the image generation. I decided to create some pixel art NFTs mostly because… Continue reading NFT Pixel Art Generated with Python
A Vector Network Analyzer (VNA) is an important test and measurement tool for RF electronics. It is capable of measuring both transmission and reflection of an electronic network. An electronic network is just a connection of electrical components, such as resistors, inductors, and capacitors, etc. This is not to be confused with an IP network… Continue reading The Amazing NanoVNA V2
After getting my first Helium hotspot and researching more about the technology I decided to get a second hotspot. But the issue became how to get one, as it can take months to receive one after a preorder. So there is substantial risk in the purchase. My first hotspot took almost 5 months and I… Continue reading SenseCAP M1 Helium Miner Setup
