I wired up all the VCC and GND pins on all discrete components, as well as the chips. Here’s what the bottom of the board looks like so far: I’m not spending a ton of engineering time on this circuit. So I didn’t do my due diligence and compute how much power each chip used … Read moreNibbler – Power Wires Complete
I finished arranging and soldering the wire wrap sockets to the board. I also wired up the VCC and GND buses. Here’s a photo of the latest version: The bus bar running down the side is ground, and the one running across the top is VCC (+5v). I have mounted most of the discrete components. … Read moreNibbler – Ready to Wire
The circuit for the 4-bit computer called Nibbler is simple. It only has 17 ICs, which means it can be easily assembled on a prototype board with wirewrap sockets. Or so I thought. First, it’s tough to find the variety of wire wrap sockets needed. Amazon actually sells a few, but you have to watch … Read moreNibbler – Getting the parts organized
Introduction I recently (like a few months ago) stumbled onto an article about the Nibbler. It’s a 4-bit computer built out of discrete logic. There is no microprocessor, so this is lower level than slapping together a minimal system with a Z-80. Here’s the original article if you want to see what I’m attempting: Nibbler … Read moreA 4-bit Computer
It’s been more than a year since I checked in, so I thought I’d post something to let anyone following this blog know that I’m still alive and kicking. I’m still working full-time in the industry. My company uses Kanban, Azure services as well as our own servers. We’re on .Net 6 for most of … Read moreIt’s been a while
I’ve done some blog clean-up and removed obsolete articles, including ones with meager traffic (like next to none). The good news is that you won’t have to rummage through articles that don’t apply anymore and I don’t have to maintain any code repos for them. The bad news is that you may have arrived here … Read moreChecking in…
I wanted to drop a post and tell everyone that I’m still around and this blog is still active. After I moved to Utah hiking consumed my summer months. My wife and I are filling our bucket list! We also bought a new house, so it’s been time consuming to repurchase everything that we needed … Read moreI’m Still Here
If you’re an entrepreneur struggling with technology, you’re not alone. Although we are always connected with a device in our hands, we’re not all experts, and there is a lot to learn. Fortunately, when you do not have time to fully understand every possible bit of technology you need to run your business, there are … Read moreThe Entrepreneurs Quick Guide To Tech and Tech Help In Today’s Digital World
This is a bit of a rant about the declining quality of today’s software and technology in general. One program that I use a lot because I hike and take thousands of pictures, is the image viewer. When I want to take a quick look at an image or flip through a series of images, … Read moreThe Sad State of Technology
Introduction I’ve been working with the IOC container pattern since 2013 and it is now baked into .Net Core. Obviously, the IOC container is the standard going forward (assuming something more fantastic doesn’t supersede it). I have a selfish reason for liking the IOC container pattern: I am a proponent of unit tests. Though I … Read moreIOC Container Memory Profiles
