Microcontroller Kits For Students

| 0 komentar |
Microcontroller (MCU) kits for students are of great interest to me for several reasons, but primarily because the Humboldt Microcontrollers Group will be offering one or several Intro To Microcontrollers sessions to any interested Humboldt State University (HSU) students this fall. Additionally, it will be great if we are able to connect with Humboldt County high school students to offer opportunities of interest to them for learning about MCUs.

(There are many middle school students doing cool things with microcontrollers. But there are only so many hours in a week, and a person has to make decisions about how to spend their limited time. My top student priority for the Humboldt Microcontrollers Group is getting as many college and high school students involved with the regions microcontroller community because that makes it easier on parents -- people in those two groups often dont need to rely on parents for transportation. However...  If any middle school students are interested in learning more about microcontrollers, or want to teach us new microcontroller tricks, wed be happy to have them at the bi-weekly meetings of the Humboldt Microcontrollers Group, and wed be thrilled to work with middle school teachers to figure out how we could help with microcontroller basics activities.)

So, back to MCU kits for students. I read an ARM press release yesterday about a new $50 Lab-in-a-box kits aimed at university students for DSP (digital signal processing) audio. While the focus of this kit isnt basics of microcontrollers, it does include an STM32F4 Discovery microcontroller board from STMicroelectronics. The press release says:
"ARM and its Partners will start shipping a digital signal processing (DSP) Lab-in-a-Box (LiB) to universities worldwide to help boost practical skills development and the creation of new ARM-based audio systems. This will include products such as high definition home media and voice-controlled home automation systems...LiB packages offer ARM-based technology and high quality teaching and training materials that support electronics and computer engineering courses. DSP courses have traditionally used software simulation packages, or hands-on labs using relatively expensive development kits costing around $300 per student. By comparison, this new DSP LiB...will cost around $50...The DSP kits, powered by ARM Cortex-M4-based processors, enable high performance yet energy-efficient digital signal processing at a very affordable price. We expect to see them being used by students to create commercially-viable audio applications."
Its not a bad thing that above Lab-in-a-box isnt a basics of microcontrollers kit. Many students may be a lot more interested in a kit focused on practical applications of microcontrollers, such as "high definition home media and voice-controlled home automation systems" than a kit that just teaches them microcontroller basics.

The next step for the Humboldt Microcontrollers Group regarding the ARM LiB kit is to contact a few instructors at Humboldt State University to find out if they are already working with ARM or one of its partners to obtain at least one LiB kit. If it appears no HSU faculty are already working on this, we can ask if they are interested in collaborating with us on an opportunity for HSU students to work with this kit. Two people at or near the top of my HSU list to contact about this are David Marshall and Ken Owens, who did a Robot Camp at HSU last week.

In the its a small world category, the Humboldt Microcontrollers Group will be an especially good partner for HSU or College of the Redwoods for working with the LiB kit. Just last week at the
Humboldt Makers meeting, John H did a fantastic talk and demo about audio with a single-board microcontroller. Part of Johns talk focused on the Wolfson audio card, so the Humboldt Microcontroller community has someone already very knowledgeable about using the audio electronics in the LiB kit. The Wolfson / Raspberry Pi combo picture on the left is from an Engadet article talking about the Wolfson card.

There are other MCU resources aimed at students. Here are a few examples -- these are aimed primarily at universities:
  • Texas Instruments TI University Program
  • Microchip Technologys Academic Program
  • Atmel University Program
  • Freescale University Programs
  • ARM University Program (which includes ARM-recommended development boards for students, as well as other ARM topics)
If you know of other student-focused microcontroller programs or cost-effective kits, please send an email with a link or other info to arcatabob (at) gmail {dott} com. It would be great to create a list of good microcontroller student kits and programs for Humboldt students to choose from. Id like to have at least three or four low-cost MCU Basics kits for student intro sessions, and it would be nice to have three or four other higher-cost kits for more involved MCU projects or workshops.

Because most teachers arent microcontroller experts, and because they are already responsible for cramming more stuff into their class time than is humanly possible, the Humboldt Microcontrollers Group might be able to offer opportunities outside the classroom for students to learn how to use Arduinos and other microcontroller-focused electronics. 

If youre a student, an instructor, or a parent of a student in Arcata, Eureka, McKinleyville, Fortuna, Trinidad, Blue Lake or any of the other fine parts of the Humboldt region who is highly interested in electronics or microcontrollers, please contact me. We can discuss ways to get you or your student(s) more involved with the Humboldt microcontrollers community.

TI LaunchPad Microcontroller

| 0 komentar |
At the May 29 meeting of the Humboldt Microcontrollers Group, Ed and Nick were discussing the Texas Instruments (TI) LaunchPad microcontroller (MCU).

This MCU was also in a few news articles recently, so I decided to do a little research on this item and see if its something worth buying for future electronics projects or experimentation.

Automation recently had an article titled "Prototype Internet Of Things Apps for $20?" This article states:
"...Texas Instruments has released it newest LaunchPad microcontroller—the Tiva C Series Connected LaunchPad. According to Texas Instruments, this MCU enables engineers to prototype a range of cloud-enabled applications, bringing expansive connectivity to any new or existing LaunchPad-based application. And it retails for $19.99. The peripherals on this MCU platform can reportedly run multiple communication stacks simultaneously, allowing engineers to develop network gateways that can connect multiple endpoints to the cloud.  Example applications include sensor gateways, industrial communication/control networks and cloud-enabled devices, as well as home automation controllers..."
At $20, the above mentioned version of the TI LaunchPad is about $10 less expensive than an Arduino Uno. And the LaunchPad MSP-EXP430G2 is only $10. Because Im very early in the learning stages of how to use MCUs and what the various features are used for, I dont yet know how to compare the TI LaunchPad to the Arduino Uno or to the many other MCUs available from DigiKey or one of the other electronic component vendors.

A May 30 article titled "Texas Instruments do-it-yourselfers show off creations at annual event" talks about a few DIY projects TI employees have done with their microcontrollers:
"...Fernandez recently created an LED light system that turns his kitchen into “a European nightclub.” He attached an LED light strip to his kitchen cabinets, programmed it using a TI microcontroller developer kit called LaunchPad and sends Twitter hashtag messages to change the color...TI test engineer Luis Flores uses a smartphone to scroll LED light images or text across sunglasses. He used TI microcontrollers, a Blue Tooth interface and a microphone. Zwerg created his low-water, switch-controlled outdoor shower with a 12-volt battery and a microcontroller. He takes it every year to the Burning Man festival in the Nevada desert...Leonardo Estevez, a researcher at TI’s Kilby Labs who has been making beer for 20 years, wanted to create a better brewing process. So, he developed a smartphone-controlled microbrewery kit based on a TI LaunchPad. Is the beer any good? “The neighbors have never complained,” Estevez said..."
Ill do some more research tomorrow and also ask Nick and Ed if theyll consider collaborating on a blog post about the specific advantages of the LaunchPad vs other MCUs.

Your Favorite Microcontroller Blogs

| 0 komentar |
Your favorite microcontroller (MCU) blog or blogs may be included in the list shown below. If not, please send website addresses for the MCU blogs you like best in an email to arcatabob (at) gmail {dott} com.

Most people probably dont have a favorite MCU blog. However, regularly reading a quality MCU blog will be well worth your while if you want to:

  1. Be aware of new MCU-related product releases.
  2. Learn new tricks and skill for using MCUs.
  3. Be exposed to different MCU projects that you might want to copy or hack.
  4. Become aware of other MCU users whom you might want to connect with.
There are two basic types of MCU blogs; ones that have a narrow focus, such as and Atmel blog or an Arduino blog, and ones that cover a wide spectrum of MCU topics, manufacturers, skill levels and applications. The Humboldt Microcontrollers Community blog tries to present a fairly wide spectrum of topics because the primary goals of this blog are to connect MCU users with each other in the Humboldt region and to increase the number of people in this area who use microcontrollers.

Below is the start of a list of blogs you should consider reading either frequently or every now and then. A post on one of these blogs may spark your interest enough that youll buy a couple new components, develop new programming skills, or start working on a project you would never have done if you hadnt read the blog post. Some of the blogs have more than just MCUs, but are pretty relevant to someone interested in MCUs.

Below is a variety of blogs -- see if one or several of them are your cup of tea.
  1. Evil Mad Scientist
  2. Adafruit Industries Blog
  3. uC Hobby -- Making things with Microcontrollers
  4. SparkFun Blog
  5. Official Arduino Blog
  6. Make: Magazine Blog
  7. Hackaday
  8. tronixstuff
  9. Embedds
  10. Atmel Blog
  11. TI MSP430 Blog
  12. 43oh -- MSP430 Projects
  13. Dangerous Prototypes
  14. Embedded Lab
  15. Electronics Lab
Tomorrow, June 26, is the next Humboldt Microcontrollers Users meeting, from 6 to 8 PM at 1385 8th Street, Arcata, California. Ill check with people at that meeting to see if they have favorite MCU blogs that arent on the above list. Hope to see you at the meeting!
