Video: Getting Your Feet Wet with Programmable System On Chip

 

Ever since I received my PSOC 4 Pioneer kit from Cypress I have wanted to play with this little mixed-signal Programmable System-on-Chip (PSOC) developer board. I love developer boards, providing that they are priced in a way to entice me to not only open my wallet but also make time in a busy schedule. I think my kit was free after winning a swag bag from Adafruit that they themselves obtained at the Open Hardware Summit and gave away on their weekly streamcast. Ultimately it was the invitation to beta test datasheet.net which also was included in that pile of swag that led to my getting involved with Hackaday.

What is Programmable System On Chip?

So what is a PSOC 4? A quick summary is that it’s based on an ARM Cortex reduced instruction set processor (RISC) and is somewhat capable of supporting shields based on the Arduino footprint, and it also uses a bright red PCB that I have come to associate with a Sparkfun PCB. What doesn’t show is the fact that this programmable system on chip has programmable analog function blocks in addition to programmable digital logic blocks. There is also some supporting input/output circuitry such as a multicolored LED and a capacitive touch sensor directly on the PCB.

This is an intriguing amount of programmability, so much so that Newark/Element 14 highlighted a “100 projects in 100 days” event on it.

Enter the IDE

Over the years I have had to create or install many Integrated Development Environments (IDE) that linked hardware to software. Knowing that you had to, and how to, implement an IDE was part of being an engineer. Nowadays with the Arduino type environment the user has an IDE pretty much as soon as they click on the executable which I find to be one of the best aspects of the genre. It was so quick in fact that I was able to get my teenaged son into writing his first program even before he remembered to do massive eye-rolls and make sounds of utter disdain. He did give up however, just shy of learning how to have the Arduino make sounds of disdain on his behalf.

We’re Not Joking Around; Something BIG is Coming

Hackaday Something BIG LogoCountdown timer, a special presentation on the first of this month, and now there’s been some weekly mystery posts. What are we playing at? We’re not playing. This is real.

That timer is now below the 10-day mark and with every passing minute we become more giddy about the unrelenting awesome that is to come. Want to know what we’re talking about without waiting until the end? Are you a clever person? Then you might just be able to figure it all out. Try to unlock the clues from past weeks, and hit the Freenode ##hackaday channel on IRC if you need some hints (we’re certainly not going to post spoilers here).

We wouldn’t mind some help with a whisper campaign as well. Spout your conspiracy theories, and your delight at solving our puzzles to whoever will listen. Get it right and you can do the “I told you so” thing for the rest of the…. oops, that would be telling.

Building the Internet of “Thing” at FTF2014

It’s official: all the hype around IoT is starting to get a bit annoying. Not because there’s anything wrong with building Internet-connected devices, but because so many people are trying to jump on the bandwagon with the same old “Future: brought to you by Megacorp #07″-mindset. Recycled visions of estranged professionals, with their homes, offices, business meetings and hotel rooms, all powered by the latest “one IoT platform to rule them all” – are back on. Even though the mythical “Smart” refrigerator didn’t changed the world back in 2001, I guess that there’s no harm in trying it again. After all, we have seen this working out great in software, with redos of dot-com era ideas turning into massive successes a decade later.

Developed on Hackaday: Olivier’s Design Rundown

The Hackaday writers and readers are currently working hand-in-hand on an offline password keeper, the Mooltipass. A few days ago we presented Olivier’s design front PCB without even showing the rest of his creation (which was quite rude of us…). We also asked our readers for input on how we should design the front panel. In this new article we will therefore show you how the different pieces fit together in this very first (non-final) prototype… follow us after the break!

MountainBeest – A Theo Jansen Creature Comes Alive in My Garage

About a year ago, a member of my family sent me a video featuring [Theo Jansen's] StrandBeest, knowing that I was interested in all kinds of wacky and hackish inventions. My initial reaction was something to the effect of “wow that’s a neat device, but that guy is a little crazy.” For better or worse, the idea that this was an incredible invention turned over in my head for some time. Eventually, I decided that I needed to build one myself.  Apparently I’m a little crazy as well.

Theo’s original beest runs on a complicated linkage system powered by wind. He was nice enough to publish the linkage lengths or “eleven holy numbers,” as he calls him at the bottom of this page. He doesn’t, however, really explain how the connections on his PVC power transmission system work, so I was left to try to figure it out from his videos.  As you’ll see from build details and video to follow, this isn’t trivial. Keep reading past the jump to learn the adversity that I encountered, and how it was overcome in the end.

VCF East Wrapup MegaPost

Header

VCF East, the fabulous retrocomputing festival held in Wall, NJ this last weekend was a blast. We had a great time, dropped t-shirts and stickers to just about anyone who wanted one, took a lot of pictures, and shot a lot of video. Now that it’s over it’s time for the post-mortem, with one insanely long post.

We saw some very cool stuff that merited its own post, and much more that we simply didn’t have time to video. The previous posts from VCF East:

There’s still tons more, including a tour of the retrocomputer museum that hosted VCF East. The biggest talk was from [Dave Haynie], lord of the Amiga giving part three of a multi-year talk on the soap opera that was Commodore International.

Heroes of Hardware Revolution: Bob Widlar

Bob Widlar (1937-1991) is without a doubt one of the most famous hardware engineers of all time.  In fact, it would not be an exaggeration to say that he is the person who single-handedly started the whole Analog IC Industry. Sure, it’s Robert Noyce and Jack Kilby who invented the concept of Integrated Circuits, but it’s Widlar’s genius and pragmatism that brought it to life. Though he was not first to realize the limitations of planar process and designing ICs like discrete circuits, he was the first one to provide an actual solution - µA702, the first linear IC Operational Amplifier. Combining his engineering genius, understanding of economic aspects of circuit design and awareness of medium and process limitations, he and Dave Talbert ruled the world of Analog ICs throughout the 60s and 70s. For a significant period of time, they were responsible more than 80 percent of all linear circuits made and sold in the entire world.
