A Lecture By A Fun Guy

Many people hear “fungus” and think of mushrooms. This is akin to hearing “trees” and thinking of apples. Fungus makes up 2% of earth’s total biomass or 10% of the non-plant biomass, and ranges from the deadly to the delicious. This lecture by [Justin Atkin] of [The Thought Emporium] is slightly shorter than a college class period but is like a whole semester’s worth of tidbits, and the lab section is about growing something (potentially) edible rather than a mere demonstration. The video can also be found below the break.

Let’s start with the lab where we learn to grow fungus in a mason jar on purpose for a change. The ingredient list is simple.

  • 2 parts vermiculite
  • 1 part brown rice flour
  • 1 part water
  • Spore syringe

Combine, sterilize, cool, inoculate, and wait. We get distracted when cool things are happening so shopping around for these items was definitely hampered by listening to the lecture portion of the video.

Microcontroller Lectures By Bruce Land

[Bruce Land] is no stranger to Hackaday as you can see from his Hackaday.io profile, if you aren’t familiar with his work [Bruce Land] is a Senior Lecturer at Cornell University. One of the courses he teaches: Digital Systems Design Using Microcontrollers (ECE4760) was recorded in 2012 and again in 2015 and the videos are available on YouTube.

AVR to PIC32

[Bruce Land]s previous set of ECE4760 lectures (2012) used an Atmel ATmega1284 AVR Microcontroller for the laboratory portion of the course. This means the lectures are also based on the AVR and if you haven’t watched them through a few times you should do. The recently updated set of lectures is based on the Microchip PIC32, more specifically the Microstick II.

Open Curriculum

You can follow the ECE4760 rabbit hole as far as you want with all the available content provided by [Bruce Land] on his ECE4760 course webpage. You can watch the ECE4760 lectures on YouTube, try your hand at the homework assignments, and work through the labs at your own pace.

New Lectures = New Shirts

One area that [Bruce Land] is unmatched and arguably uncontested is his shirt collection, we are continuously impressed with these original works and wish they were available for purchase (wink/hint c’mon [Bruce] throw us a bone!). If you don’t know why the rest of us aren’t able to obtain the wonderful shirts [Bruce Land] wears you clearly aren’t subscribed to [Bruce Land]s YouTube channel, you should rectify that wrong and log some ECE4760 lecture hours starting with the video after the break.

Demonstrating Science At Harvard University

What if there was a job where you built, serviced, and prepared science demonstrations? This means showing off everything from principles of physics, to electronic theory, to chemistry and biology. Would you grab onto that job with both hands and never let go? That was my reaction when I met [Dan Rosenberg] who is a Science Lecture Demonstrator at Harvard University. He gave me a tour of the Science Center, as well as a behind the scenes look at some of the apparatus he works with and has built.

Cornell ECE 4760 Lecture Videos Now Online

Whenever we hear about ECE 4760 we take notice. That’s because a ton of fantastic hacked together projects have resulted from the class. It’s offered at Cornell University and focuses on designing projects based on microcontrollers. We look at it as a ‘how to connect everything to your microcontroller’ guide. The good news for you is that 34 lecture videos from the Spring 2012 ECE 4760 class are now available to watch for free online. When coupled with the course webpage itself (which outlines the reading, labs, and homework) this turns into an opportunity to work through the entire course on your own schedule.

If you need a brief preview, here’s a couple random things we’ve seen as final projects from the course: a digital saxophone, a handwriting decoder, and a haptic feedback unit for building your biceps.

We’re still working our way through the Nand2Tetris project, but we’re putting these lectures on our watch list for later.
