Took this screenshot while I waited for the AddOhms Q&A #02 Video to finish rendering. What could I be pondering?
Think you can do without Pull-Up Resistors? Only Chuck Norris doesn’t need them.
IoT (n): Internet of Things
- Things that connect with the internet, to share information.
- Devices that communicate with each other.
- No wait. Nothing does. It’s the Internet Of Nothing!
It continues to amaze me how few Internet of Things (IoT) devices actually communicate with each other. Isn’t Internet connectivity suppose to make it EASIER for things to talk? Computers have been communicating with the Internet for 45 years. Why can’t Light Bulbs from two manufacturers do it?
At some point someone has to come along to “fix” this situation. What is that solution going to look like and how much longer do we have to wait? Let’s get out of the HealthKit era of things talking to each other.
While I was attending a material science conference, I learned the value of listening to something new. The paper I came to see was finished, and the next was about to start. It was titled, “Additive Manufacturing.”
I almost left!
What a dull phrase, right? Well, I was stuck in the middle of a row with four people on either side of me. So I decided, it was a good time to catch up on Reddit. What I didn’t realize is “additive manufacturing” is what almost everyone else in the world calls “3D Printing.” Plus, this presenter was talking about doing it with metal!
When you think about it, most extrusion-based 3D printers are laying down material one layer at a time. In other words, they are manufacturing an object by “adding” material. See the connection? Most people probably lump 3D-printing into rapid prototyping and additive manufacturing into a “real” production process.
One more story.
At SXSW one year, I attended an event held by Shapeways. Objects they made were all over the venue, and they looked incredible. Plus, some were for sale. My favorite? Super Mario Bros related stuff. Do a search for “Mario” in Shapeways marketplace for some neat things to add to your desk.
Use de-caffeinated Silicon, of course!
I am not a fan of relying on the Autorouter in EAGLE — or any PCB CAD software for that matter. When laying out a board, I’ll use the autorouter to get an idea if the part placement is going to work or not. In this case, I was reminded how much autorouters suck! Even after running for while, the autorouter could only route up 50% of the nets (signals).
Never Trust The Autorouter
It only took me about 20 minutes to start over and finish the manual layout. I still want to clean it up a little, but over all, I beat the Autorouter.
What is the board anyway?
In January I visited Tokyo on my annual work trip. While there, I ran over to Akihabara to check out a used media store called Traders. The multi-level store (like all those in Tokyo) sold used video games and movies. Each floor featured different platforms. My favorite was the 2nd floor which was all retro 8, 16, and 32 bit systems. Piles of Famicoms (NES), Super Famicoms (SNES), Mega Drives (Genesis), and other systems were all around. In the middle of the floor were racks of cartridges.
While there I picked up a couple of Rockman (Mega Man) carts, Super Mario brothers, and even Adventure island.
A US-based NES can play Famicom games since the basic hardware is the same. However, the pin outs are slightly different. Also, US-based NES systems look for a lock-out ship (CIC) that Famicoms don’t have. Fortunately I ran across a project that uses the ATtiny (AVRCICZZ) to emulate the lockout chip. So armed with that and some pinouts, I’ve created an adapter.
Keep subscribed, after a few more touches, I’ll post the EAGLE files as an Open Source Hardware (OSH) project.
Fun with the meme generating. When it comes to adding decoupling caps, Make It So.
