  • Automated Hydroponic System Build
    Hydroponic farming is a method of growing crops without soil, with the main benefits of environmental and nutrient control, water conservation, and reduction of labor. This technique relies on a number of technologies that the principles of automation can be applied in order to improve yield and consistency. In this article and accompanying video, I’ll […]
  • 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, […]
  • 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 […]
  • 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 […]
  • 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 […]
  • 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 […]
  • Artificial Bat Cave
    In 2012, the Tennessee chapter of The Nature Conservancy constructed an 80-foot, underground artificial bat cave. This was to serve as a site for bat research in order to develop knowledge about bat white-nose syndrome and explore potential treatment methods to help increase survivorship among bats affected by this deadly disease.
  • Mushroom Cultivation Revisited
    Update: A newer version of Mycodo 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 […]

  • Garden Irrigation Automation
    I found the highest and brightest part of my yard, cleared the vegetation, lightly tilled the earth, and laid bricks and 4x4s to walk on. I erected a fence from bamboo harvested in the yard, to protect it from an American bulldog that shares the yard.
  • 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 […]
  • Distillation Automation v1
    I discovered the cheap tabletop distillation unit that I purchased had design flaws beyond mere poor craftsmanship. Further insult was that with the seller’s no refund policy meant it was mine for good. I had been burned, but that didn’t get me down. The flaws were minor, but made proper operation a challenge. However, I […]
  • Moto Security System
    Building a vehicle security system has been in mind for a while, however, a recent surge in motorcycle thefts from my university has forced me to pick up the pace with development. What this circuit does is diable the fuel pump, once the bike’s power is turned on from the ignition, until a magnet must […]
