Remote Radiation Monitoring

Radiation is the transmission of energy through space in the form of a particle or wave. These can be generated by instruments or produced naturally. One of the most common uses of radiation is from radionuclides, or radioactive isotopes, that release radiation during decay, or degradation. These radioactive materials are often used for cancer therapy, research, and energy production.

Outdoor LoRaWAN Gateway

I’ve been heavily involved with sensors and remote sensing for many years. Recently, I’ve become intrigued with remote sensing, and began my exploration with LoRaWAN. However, to start experimenting with sensor nodes, I would need a gateway to receive all my node transmissions (as well as send back any data to the nodes). Below is how I built and implemented my outdoor LoRaWAN Gateway.

Bringing a Vintage Telegraph into the Digital Age

I recently inherited a key on board (KOB) telegraph that my late grandfather used to practice Morse code with when he was a kid (Figure 1). A little bit of curiosity of how it would work and a little bit of displeasure from seeing it sit and collect dust, I began a journey to resurrect the old machine and develop some software to bring it into the digital age. If you’re eager to see the final result, or just don’t want to read, skip to the end for a video demonstration.

Environmentally Controlled Apiary

Ascosphaera apis is a fungal pathogen of honey bees (Apis mellifera) that has been a significant contributor to Colony Collapse Disorder (CCD), a phenomenon that results in the death of a honey bee colony. CCD has been responsible for a significant decline in honey bee populations around the world, and has been attributed to a number of factors, including pesticide use, subpar farming practices, parasitic insects, and pathogen insults.

Mushroom Cultivation Revisited

Update: A newer version of this project has been released. Read More >>

There have been many initiatives undertaken to maximize mushroom cultivation productivity, and although variations exist between species, manipulation of environmental conditions has demonstrated some of the most dramatic effects on yield. Temperature, humidity, and carbon dioxide concentration have been identified as some of the most crucial factors for promoting mycelial colonization, primordia formation, and growth of fruiting bodies, or mushrooms. Additionally, each stage of development requires specific conditions for optimal growth. As such, the more precise these conditions can be controlled, the greater the yields that are possible.
