Gravity: Analog Soil Moisture Sensor

A soil moisture sensor can read the amount of moisture present in the soil surrounding it. It’s an ideal for monitoring an urban garden, or your pet plant’s water level. This is a must have component for a IOT Garden / Agriculture. The new soil moisture sensor uses Immersion Gold which protects the nickel from oxidation. Electroless nickel immersion gold has several advantages over more conventional surface platings such as HASL, including excellent surface planarity, good oxidation resistance, and usability for untreated contact surfaces such as membrane switches and contact points.

This Soil Moisture Sensor uses the two probes to pass current through the soil, and then it reads that resistance to get the moisture level. More water makes the soil conduct electricity more easily, while dry soil conducts electricity poorly. This sensor will be helpful to remind you to water your indoor plants or to monitor the soil moisture in your garden.

Fermion: BLE Sensor Beacon

BLE Beacon, also known as Low Energy Bluetooth Beacon, is a small wireless device that broadcasts signals using BLE technology. Due to its broadcast nature, pairing is not required between the beacon and receiving devices. Each beacon contains a unique identifier, detectable by nearby devices equipped with Bluetooth technology, such as ESP32 and smartphones supporting BLE scanning.

This Bluetooth beacon has a built-in 11-bit ADC, Fermion version, and multiple I/Os that can be multiplexed to SDA/SCL while broadcasting over Bluetooth. Users can access sensor data within broadcast range on a Bluetooth-equipped device such as a Smartphone or ESP32. This BLE beacon has a built-in 11-bit ADC and an I2C interface, allowing it to real-time collect and broadcast data from various types of sensors, including analog, digital, and I2C sensors.

SparkFun Triple Axis Accelerometer Breakout – MMA7361

This is a breakout board for Freescale’s MMA7361L three-axis analog MEMS accelerometer. The sensor requires a very low amount of power and has a g-select input which switches the accelerometer between ±1.5g and ±6g measurement ranges. Other features include a sleep mode, signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear freefall. Zero-g offset and sensitivity are factory set and require no external devices.

This breadboard friendly board breaks out every pin of the MMA7361L to a 9-pin, 0.1″ pitch header. The sensor works on power between 2.2 and 3.6VDC (3.3 Volt optimal), and typically consumes just 400µA of current. All three axes have their own analog output.

  • Two selectable measuring ranges (±1.5g, ±6g)
  • Breadboard friendly – 0.1″ pitch header
  • Low current consumption: 400 µA
  • Sleep mode: 3 µA
  • Low voltage operation: 2.2 Volt – 3.6 Volt
  • High sensitivity (800 mV/g at 1.5g)
  • Fast turn on time (0.5 ms enable response time)
  • Self test for freefall detect diagnosis
  • 0g-Detect for freefall protection
  • Signal conditioning with low pass filter
  • Robust design, high shocks survivability

NeoPixels

The WS2812 Integrated Light Source, or NeoPixel in Adafruit parlance, is the latest advance in the quest for a simple, scalable and affordable full-color LED. Red, green and blue LEDs are integrated alongside a driver chip into a tiny surface-mount package controlled through a single wire. They can be used individually, chained into longer strings or assembled into still more interesting form-factors.

NeoPixels don’t just light up on their own; they require a microcontroller, such as Arduino, and some programming. We provide some sample code to get you started. To create your own effects and animation, you’ll need some programming practice. If this is a new experience, work through some of the beginning Arduino tutorials to get a feel for the language.

NeoPixel Stick – 8 x 5050 RGB LED

Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. Each one has constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. The LEDs are “Chainable” by connecting the output of one stick into the input of another. There is a single data line with a very timing-specific protocol.

I am a highly skilled programming language, microcontrollers, IoT, robotics and etc; with over 45 years of experience in various industries. I graduated from McGill University, Montréal, Québec, Canada with B.Sc. and D.D.S. degrees. I started consulting with small and medium-sized businesses in my native Canada in the mid-eighties and by the mid-nineties I was consulting for large corporate clients like Fannie Mae, KPMG Peat Marwick, Chase Manhattan Foreign Trade Division (Hong Kong), Warner Lambert and a variety of other firms in the Washington, DC and New York City area. Later on I worked with clients in Europe, Mexico, and Latin America.

I have worked, lived and traveled all over the world and I am a trilingual (English, French, and Spanish).

Over the years I have been the CTO of various early stage IT startups, the owner of an IT consulting company (desktop, web, mobile, microcontroller and embedded systems) with clients worldwide, in charge of R&D projects to integrate hardware and software solutions in innovative ways, director of technology for a business software development company, designer and integrator of electronic hardware and head developer on a variety of software and technology projects.

I have seen many trends come and go, good and bad, and lived through many major industry changes. I do deplore some of the current state of the industry, and applaud some of the new trends. My wife had been telling me for years to write about the the industry as we discuss things a lot and she always tells me that I was born to teach, or preach when I get excited about a subject. Since my motto has always been to learn something new daily, and that a wasted day is one where you learn nothing new, I decided to share some of that hard-earned let’s call it “Wisdom” for lack of a better term.

I know that I am considered as a dinosaur in this business where you are considered old when you hit 25, but there are some of us old fogies at over twice that, that are still active and can still provide a full contribution to this or these fields. Besides consulting and custom programming, I also offer electronic hardware integration and design, hardware/software integration as well as R&D services. I provide my services worldwide and can work from my office or yours depending on your project’s needs.

Why “The Alpha Geek”?

Alpha Geek

Why “The Alpha Geek”?

I have said “Once a Geek always a Geek” so many time in describing myself. Since I was a small child the main goal in my life has been to learn new things daily. While I write this, on the whiteboard in front of my me in my office, is written in large letters “What new things have you learned today?”. It is a reminder to myself that the day will not be complete until something new is learned. Luckily for me in my line of business you would have to work very hard not to learn something new on a daily basis.

With that attitude in mind since childhood it was very difficult not to grow up and become a full-fledged Geek at an early age. In my early teens I was into photography and processing and printing my own B&W photos in a darkroom I had built with the help of my Mom in our basement in Canada. That was one of my many interests at the time and I can’t even remember how many different “Geeky” things I have done over the years. I got into electronics when I could not afford to buy a proper darkroom timer and I saw some article, probably in some electronics magazine, that explained how to build a simple timer that blinks a LED at one second intervals. After a trip, probably to Radio Shack, to buy a 555 timer IC, a LED, some resistors, wires and a small perforated circuit board. After that I was hooked on electronics projects from that day.

Some years later, while I was an undergrad at university, I was learning mainframe programming in Fortran and assembler programming for some mini-computer I do not remember. Since they were giving us only a few minutes of mainframe processor time a semester a bunch of friends and I bought one of the original Apple 1 kits and I built it for the group and we used that for a few years to supplement our mainframe time. Then followed a Timex Sinclair, a Commodore 64, a Portable Commodore 64, a 128, a PC XT clone with a huge 10Mb hard drive and then hundreds of PCs, laptops, Palm PDAs, tablets and electronic computing devices and gadgets of all kinds.

When I started consulting in 1983 a major part of my time was spent integrating and repairing computer hardware and I even worked for a few years repairing systems nobody else could fix. Nowadays besides programming some business applications on a variety of platforms I still spend a lot of time integrating specialized hardware with software and designing electronic devices of all kind. Since I started with that first simple electronics project over 45 years ago, the Geek in me is still going strong and even though the “Geek” badge is generally used describing the younger crowds I think that a grizzled grey-haired Geek veteran like me deserves the title of “Alpha Geek”. Experience should count for something…

If you noticed I capitalize “Geek” as I think it is a term of respect and not one of derision. I hope that all the Geeks out there will love visiting this blog that will grow to host many projects and features. I also hope that it will help in convert Geeks-in-Training to full-fledged card-carrying Geeks like that first project did for me so long ago.

In the meantime enjoy your stay and let’s Geek Out!

Moteino

Moteino began as a low power wireless Arduino compatible development platform based on the popular ATmega328p chip used in the Arduino UNO. There are now several Moteino development boards including MoteinoMEGA based on the Atmega1284P and MoteinoM0 based on the SAMD21G18 Cortex M0+. For programming you will need an external FTDI-Adapter to load sketches, the advantages being lower cost, smaller size.

Servo Motor

A servo motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servo motors.

Servo motors have been around for a long time and are utilized in many applications. They are small in size but pack a big punch and are very energy-efficient. These features allow them to be used to operate remote-controlled or radio-controlled toy cars, robots and airplanes. Servo motors are also used in industrial applications, robotics, in-line manufacturing, pharmaceutics and food services.

Pololu Adjustable Boost Regulator 2.5-9.5 Volt

This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 Volt from an input voltage as low as 1.5 Volt, all in a compact. A trimmer potentiometer lets you set the boost regulator’s output voltage to a value between 2.5 and 9.5 Volt.

Bluetooth Server and Client

Connect the SparkFun BME280 and CCS811 this is the “Server” board. Upload SparkFun Thing Plus the Server code to the board using the USB cable. When uploading is complete, disconnect this board from the computer. Now, connect the Lithium Ion battery to the “Server”. Next, connect the second SparkFun Thing Plus to your computer and upload the Client code to the board. We have two Arduino sketches to upload to the SparkFun Thing Plus boards. Upload the first sketch to the Server SparkFun Thing Plus and the second sketch to the Client SparkFun Thing Plus.

Microcontroller

A microcontroller is a small computer on a single Metal-Oxide-Semiconductor (MOS) integrated circuit (IC) chip. A microcontroller contains one or more CPUs (Processor Cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips.

A microcontroller is a “Simple Computer” that runs one program in a loop. They are designed to perform a single, specific task. In this guide, we’ll be focusing on microcontrollers that have breakout boards, or a board that makes it easier to connect to and program the microcontroller. On a breakout board, the microcontroller pins are soldered to a printed circuit board, headers or other connectors are added to the PCB, and some basic firmware, or permanent software, is loaded to prep the microcontroller to receive signals.

There are different microcontrollers and it can be daunting to get started, especially if you’re just getting into electronics.

  • Arduino Uno, etc, (5V/16MHz, 3.3V/8MHz) is a microcontroller board based on the ATmega328.
  • Arduino Micro, etc, (5V/16MHz, 3.3V/8MHz) is a microcontroller board based on the ATmega32U4.
  • Arduino Mega 2560, etc, (5V/16MHz) is a microcontroller board based on the ATmega2560.
  • Arduino Due, etc, (3.3V/84MHz) is a microcontroller board based on the AT91SAM3X8E.
  • Arduino Zero, etc, (3.3V/48MHz) is a microcontroller board based on the ATSAMD21G18 ARM Cortex M0+.
  • Arduino Nano 33, etc, (3.3V/120MHz) is a microcontroller board based on the ATSAMD51 Cortex M4.
  • Espressif ESP32 WROOM, etc, (3.3V/240MHz) is a microcontroller board based on the Espressif Xtensa® dual-core 32-bit LX6.
  • Raspberry Pi 4 Model B (5.1V/1.5GHz) is a microcontroller board based on the Broadcom BCM2711, quad-core Cortex-A72 (ARM v8) 64-bit SoC.
  • Raspberry Pi Zero W (5.1V/1GHz) is a microcontroller board based on the Broadcom BCM2837B0 64-bit ARM Cortex-A53 Quad Core Processor SoC.
  • Etc…
