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.

LoRaWAN Tracker and Mapper

LoRaWAN is a great long-distance, low-power transmission protocol. One of the questions that often comes up after deploying a gateway and nodes is “what’s the greatest distance I can successfully transmit between my gateway and node?” You could watch your Application traffic on The Things Network as you move to strategic locations and see if packets appear. However, an automated approach to this could save time and allow you to cover more ground. To do this, you’ll need a node with a GPS to send its location and software to aggregate the received data on a map to show the node transmission locations. This way you can have the node automatically transmit at a rapid interval as you walk, cycle, or drive to various locations.

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Update: A newer version of this project has been released.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

Distillation Automation v2

With the acquisition of a new distillation unit, I decided to transfer and adapt the Arduino control interface from my previous distillation unit to this one. I wanted a redesign that would reduce size and increase functionality. The 120VAC solid state relays, Arduino, and a resistor were the only components that made the cut into the new design. A 16×2 LDC and a rotary encoder with a push button were picked up for input and feedback. The rotary encoder allows unrestricted rotation as well as having a normally open push button. This, in combination with an LCD, seemed to be the simplest interface with the greatest functionality.
