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 more Nibbler – Power Wires Complete Categories Digital Electronics , Nibbler - 4 Bit Computer , TTL Logic Leave a comment Nibbler – Ready to Wire April 27, 2024 April 20, 2024 by Frank DeCaire 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 more Nibbler – Ready to Wire Categories Digital Electronics , Nibbler - 4 Bit Computer , TTL Logic Leave a comment Nibbler – Getting the parts organized April 27, 2024 April 7, 2024 by Frank DeCaire 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 more Nibbler – Getting the parts organized Categories Digital Electronics , Nibbler - 4 Bit Computer , TTL Logic 2 Comments A 4-bit Computer April 6, 2024 February 4, 2024 by Frank DeCaire 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 more A 4-bit Computer Categories Digital Electronics , Nibbler - 4 Bit Computer Leave a comment It’s been a while August 6, 2023 August 6, 2023 by Frank DeCaire 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.

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 more Checking in… Categories Uncategorized 4 Comments I’m Still Here April 6, 2021 April 6, 2021 by Frank DeCaire I wanted to drop a post and tell everyone that I’m still around and this blog is still active.

One program that I use a lot because I hike and take thousands of pictures, is the image viewer.

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.
