Humboldt MCU Opportunity Tech Companies Recruiting IoT Developers

One of my goals for this blog is to identify ways for Humboldt microcontroller (MCU) users to earn money and to try to highlight those money-making opportunities for people who are interested in them. It will help Humboldt people and the regional economy if we can increase the number of Humboldt MCU-related paid projects and jobs.

Wired.com had a short July 25 article, "Tech Giants Begin Recruiting for the Next Big Platform Wars", which talked about a technology-economy trend that Humboldt MCU people should be aware of and should look at as an opportunity for projects or jobs. The article says that the Internet of Things (IoT) is going to be a huge revenue opportunity for MCU developers, the next big platform. The killer app for the IoT hasnt come over the horizon yet, and there is no clear leader among companies competing to cash in on the billions of dollars expected to be spent on embedded computing systems and other IoT products and services. Even though no company has a firmly established lead, those organizations who want to have a chance in this race are hiring technical people, including MCU developers, to create and improve their organizations products. As Wired puts it:
Microcontroller (from ti.com)
"The Internet of Things is still young, but it’s real. There are already dozens of internet-connected devices available, ranging from home-automation tools to wearable fitness trackers. And it’s about to start growing at an even faster pace. According a new survey...17 percent of the world’s software developers are already working on Internet of Things projects. Another 23 percent are planning to start an IoT project within the next six months. The most popular devices? Security and surveillance products, connected cars, environmental sensors and smart lights and other office automation tools. The world’s largest tech companies are already in fierce competition to attract developers to their respective connected device platforms. After all, the winners of these new platform wars will define the future of computing."
Two previous technology-economy trend platforms early stages that employed a lot of developers were when businesses started having websites on the Internet and when the iPhone catalyzed a huge market for smartphone apps. New sustainable trends have a tipping point where the trend actually becomes an important economic factor and creates a significant amount of ongoing sales and reliable employment. The IoT appears to be approaching that tipping point, and the Wired article is saying the trend is sustainable and there will be a large number of steady employment opportunities for IoT developers. The Barrons.com article "Silicon Labs Tuned In for Upside" phrased it this way:
"...we dont think IoT for Silicon Labs will turn out to be an overextended hype cycle. Connected/smart-home adoption has parallels to smartphones in 2008, where developers created unanticipated high-value applications on a platform to drive rapid adoption. From that perspective, 50 billion IoT devices by 2020 does not seem unreasonable."
Other recent articles about MCUs, embedded computing and the IoT have also talked about MCU-developer opportunities in the upcoming months and years. So the question at this point is, how can Humboldt developers get involved with the IoT platform to make money? Ill talk more about this topic in some of the future posts on this blog. But for now, Humboldt MCU developers and users might consider doing some or all of the following activities.
  1. Learn a lot about the IoT and microcontrollers and keep up-to-date on these two topics.
  2. Learn more about the IoT and MCUs by designing and building unique projects and document them online.
  3. Use the internet to document and promote your IoT and MCU knowledge and skill.
  4. Teach a class about Arduinos, MCUs or the IoT.
  5. Build and promote interesting MCU / IoT products and sell them online.
  6. Identify and reach out to knowledgeable and interesting people who are relatively well-connected in the IoT and MCU communities.
  7. Use craigslist and other online developer job boards to look for MCU / IoT job or project opportunities and to advertise your availability for MCU / IoT projects and employment.
All the above activities can be done without participating in any of the Humboldt Microcontrollers Group meetings or collaborative MCU projects.

But the above money-making activities can also be done with people who are active in the Humboldt Microcontrollers Group. In my experience, its often more fun and more interesting to work on projects or activities with other people who have complementary or similar knowledge and interests. If youre interested in discussing any of the above IoT money making opportunities, come to the next MCU meeting. Or email me at arcatabob (at) gmail {dott} com.

Kaffir Lime Flowering ✓

Kaffir lime - Citrus Trees - Canada




So Ive just noticed our kaffir lime has started to flower/fruit. To think here in Canada it flowers in march/april is quite different (but I could be tricking myself). The strange thing was, I think this was by accident. A while back I brought a few Meyers from our hot sunroom
( 25c+ )  into our greenhouse  ( 13c ) during the winter and almost instantly they started to flower. This same situation/reaction happened with my Star ruby grapefruit. Now after moving our kaffir lime from the greenhouse into the sunroom there was an instant flowering. So I cant be positive of all varieties of citrus but it seems like they are like other species of plants where cold weather signals them to fruit, almost in a dash to save it genes. This is great for growers in canada with stubborn trees that are harder to flower ( To bad this wont work with bananas tho). Try setting your plant out side for a minute  ( not directly on the cold ground or in snow ) this might  stimulate that tricky tree. Please feel free to comment if this scenario works for you or what trees/plants you have found this trick works with.

The kaffir only gets half light but still fruits
We also noticed a friendly new predator spider the other day, while weve seen one like him thats all black with white stripes, this one was much larger with almost a blueish white on the stripes, not sure if its just more mature but Ive never seen one this size before.

Mutli Phase Humboldt MCU Garden Project

As yesterdays Humboldt Laser Harp post indicated, the microcontroller (MCU) music group project is well under way. So now Im thinking about how to get the second group project started in the Humboldt Microcontrollers Group, one involving gardening.
MCU and sensors for potted plant

Several people whove been at Humboldt Makers Group meetings or the MCU group meetings have said theyre interested in MCUs and gardening. And it seems like lots of other people in Humboldt County might have an interest in ways to improve gardening. There are lots of organic gardeners in the area, and agriculture has been part of the Humboldt economy for much of the areas history. So Ive decided to outline a multi-phase approach to a collaborative project focused on MCU gardening. And a significant part of this collaborative project will be identifying and reaching out to Humboldt people who are involved in gardening or agriculture and might be interested in sharing their knowledge and / or participating in this project.
MCU and hydroponics

Two long term goals I have for the MCU gardening is to be involved with a successful hydroponics system and a successful aquaponics system. There are lots of websites and projects on the Internet that tell a person how to do hydroponics or aquaponics, but Im an engineer, and I like to understand what Im doing. Plus I dont have a lot of money to spend on these projects. So my preferred approach to MCU gardening is to start out small, and get more complex after I understand the technology and green thumb art involved with each part of the MCU garden project.

Below are proposed MCU garden project phases. If we get the right people involved with the project and if we can secure funding of some type for the project, we can move very quickly through the phases or work on more than one phase at a time. So if you know people whod like to participate in this project or know of money that can be used for purchasing electronic components and supplies for this, please contact me at arcatabob (at) gmail {dott} com. These are the proposed phases for the Humboldt MCU Garden group project:
MCU and aquaponics (from dzbc.org.cn)
  1. Grow one plant indoor in soil.
  2. Grow four to eight plants indoor in soil.
  3. Grow four types of plants outdoor in soil.
  4. Grow one tray of plants indoors in hydroponic system.
  5. Grow three types of plants indoors in hydroponic system.
  6. Grow one type of plant in aquaponics system.
  7. Grow three types of plants in aquaponics system.
Phase 1 of the Humboldt MCU Garden project is simple and low cost and will help us learn the basic principles of MCU gardening. Phases 2 through 7 can easily be redefined as we get more people involved in the project and we learn more about what we dont know about MCU gardening.

The first draft design of the Humboldt MCU Garden project includes:
  1. One type of plant.
    LEDs and lettuce
    1. Lettuce is my first choice, partly because of whats being done with optimized lettuce mcu gardening in Japan and other places (see my blog post "LED Lettuce, The HydroTower And LED Humboldt Hydroponics.") We might be able to find useful data about optimum growing conditions for lettuce (light wavelengths, relative humidity, nutrients, temperature, etc.).
    2. If other people who want to participate in the Humboldt MCU Garden project prefer to grow something other than lettuce and have information about good growing conditions for that plant, Im willing to switch from lettuce.
  2. Growing container.
    1. The type of growing container probably wont be too critical for Phase 1. Mainly something large enough to hold the soil and drainage system that will provide good growing conditions for the plant.
    2. A five gallon plastic bucket is one option, especially if we can find a free one.
    3. We need to figure out where the container with the plant and MCU Garden system will be kept. It seems like Phase 1 should mostly be indoors because that means we dont need to have a rain-proof system. But having a Phase 1 container thats easily movable would be nice so we can roll or carry the container outside on nice days.
  3. Growing condition sensors
    1. Light sensor -- very important so we get good photosynthesis (and good respiration?).
      One type of light sensor (from Adafruit)
    2. Soil moisture sensor -- very important because too dry means dead plant and too wet means dead plant.
    3. Temperature sensor -- important for growth, especially during Humboldt winters. Temperature will be less critical for plants like lettuce, but very critical for plants like tomatoes.
    4. Relative humidity sensor (RH) -- RH wont be critical for lettuce growth in Phase 1, but it will be critical as the projects future phases try to minimize water usage and as we try to grow RH-sensitive plants like redwood trees.
  4. LEDs for indoor gardening
    1. RGB LEDs will let us adjust the light if we want
    2. Red and Blue LEDs appear to be used for optimum lettuce growth.
    3. Research and / or people who know plant growth lighting and LEDs are required.
  5. MCU to gather and record sensor data
    1. Which MCU we use for the Humboldt MCU Garden project depends partly on who wants to be involved with the project.
      1. If we can get a sponsor for the Humboldt MCU Garden project, such as an MCU manufacturer or distributor, Ill use whichever MCU they manufacture or distribute!
      2. If no MCU manufacturer or distributor sponsor can be recruited, the MCU will be determined by whoever takes the lead on programming for the project.
        1. If Ed takes the lead, well probably use a Texas Instruments MCU.
        2. If Josiah takes the lead, or if Im filling that role, it will likely be an Arduino or Arduino-compatible.
        3. If someone other than Josiah, Ed or me volunteers to lead the garden-variety programming for this project, that person can choose the MCU type.
  6. Type of soil
    1. Determining what type of soil to use will require research or a project member who has good experience with growing plants indoors in containers.
    2. The type of soil will likely affect other gardening aspects such as what nutrients we need to add and the soil moisture measurement.
  7. Fertilizer and trace nutrients to add
    1. Fertilizer and trace nutrients is another topic that will require research or a project member experienced in the art.
    2. Might want to evaluate whether pH or some other batch or continuous sensor (pH? nutrient analysis?) should be used to track nutrient levels.
  8. Data gathering and analysis
    1. There are no specific requirements for data gathering and analysis for Phase 1 since its such a simple system. However, part of the purpose of Phase 1 is to learn how to effectively monitor growing conditions, so it makes sense to establish good gardening data practices (GGDP) for those growing conditions and different types of sensors.
    2. As part of my goal to get Humboldt people more involved in the Internet of Things (IoT), it would be good to use services like open data bases and IFTTT (If This Then That).
    3. One gardening data goal is to use that data to automatically track, alarm and interpret the data generated by the sensors. It would be nice to generate online graphs and have alarms sent out by IFTTT when growing conditions reach or approach setpoints where action needs to be taken.
The above outline give you an idea of what I think Phase 1 of the Humboldt MCU Garden group project should look like. Next steps for me to get this project rolling are (1) talk to and try to recruit a couple people whove expressed an interest in MCU gardening, (2) promote the project to other people in the Humboldt Makers and MCU group and try to recruit some of them, (3) develop a one-page MCU project proposal that I can use to pitch to potential sponsors, and (4) continue to do research for Phase 1 topics like sensors, nutrients and soil types.

If you are interested in this project or know someone who might be, please email me at arcatabob (at) gmail {dott} com or come to an MCU group meeting or Humboldt Makers meeting in the near future.
