I admit it: I'm a total geek. I love electronics, programming, 3D art, vintage Apple hardware, and whisky. I'm always juggling half a dozen projects. I also enjoy documenting it all: my successes, my failures, my experiences... and everything geeky along the way.

Flashing a Nixie with an Arduino

blogEntryTopper
I’m in the very early stages of prototyping a nixie clock. I picked up some MJE340 power transistors to switch on some IN-3s. I can then use a digital pin on my Arduino to turn on the IN-3s through the transistor. I’ll then have myself a blinking colon for my nixie tube clock. Read More...

IN-12 Nixie Breakout Board

blogEntryTopper
After a long month of waiting for PCBs, nixie pins, nixie sockets, and resistors....I was finally able to assemble my IN-12 Nixie Breakout Boards. Too bad the pinouts are backwards and half the digits don’t work. See, this is why we prototype! Read More...

GPS Clock Prototyping, Part V

blogEntryTopper
Wow, has it been a long time since I worked on the GPS clock. A whole 8 months! The prototyping and PCB design was completed a long time ago. I just didn’t want to order the PCBs until the code was complete. The PCBs cost $60 bucks from OSH Park. That’s a lot of money to spend on PCBs that might not work, so I really wanted to make sure everything was solid. I just keep getting distracted with other projects. It’s time to just bite the bullet and finish it. Read More...

Bench-Top Power Supply, Part 2

blogEntryTopper
Finally! After waiting 3 weeks for my ATX Breakout Board to arrive, I got to work on my DIY bench-top power supply. I really like the way it came out. It’s going to come in especially handy with all the upcoming nixie projects I have in mind. I’m going to get a lot of use out of it. Read More...

The 2014 Scottish Games

blogEntryTopper
My wife kicked off with the kids to her friend’s house for the weekend. While I’d love some peace and quiet to work on PCBs, 3D renders, and code, I figured I’d bugger off and do something too. While I treasure my “me time”, this is also the weekend that the Capitol District Scottish Games are held. Any excuse to wear my kilt. Gotta represent! Read More...

Bench-Top Power Supply, Part 1

blogEntryTopper
My wife came home today with her friend’s 12 year old junker of a Dell. The machine is toast. The motherboard is shot. The only thing left to do was gut it for parts. The only real gem out of the lot was this 250 watt ATX power supply. I’d love to make use of Dangerous Prototypes’ ATX Breakout Board and make a bench-top power supply for prototyping. Read More...

Got My Nixies Powered!

blogEntryTopper
Ohhhh yeaaah!!!! It only took me a decade, but I finally got one of these nixies fired up! As I mentioned in my previous post, I picked up a new nixie power supply kit off eBay for under $10 bucks. It worked like a charm. Read More...

Nixies!

blogEntryTopper
I’ve been wanting to build a nixie clock for over 15 years, ever since I saw the TTL nixie clock my Dad build in the 70s. Being a young lad, I was very apprehensive in dealing with the high voltages required to fire nixies. I just never had the guts. Back in 2001, I figured I’d start out small and design a TTL clock using 7490s and 7-segment LEDs. The whole clock runs off 5V and there’s zero chance of being electrocuted. It’s been a long time coming, but I think it’s finally time to bite the bullet and make a nixie clock. I’ve learned so much over the past few years working with the Arduino platform, that I’ll be able to apply what I’ve learned from all my other clock projects. Read More...

Upgrading My Old 7490 Clock, Part V

blogEntryTopper
I did it! I finally finished upgrading the clock internals and the enclosure. I think it came out amazing. I just can’t believe after all these years that this clock finally looks like something I can be proud to display. I’m really happy with the results. Read More...

Upgrading My Old 7490 Clock, Part IV

blogEntryTopper
The last prototype Arduino board I made for the 7490 clock rework didn’t turn out as well as I had hoped. The board did what it was supposed to do, but the implementation wasn’t that great. The more I thought about it, the more it became clear that the Bare Bones Arduino boards I designed months ago were the perfect solution. After all, it’s projects like these that inspired me to create the Barebones Arduino in the first place. Read More...
