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.

Large VFD Clock - Part II


blogEntryTopper
The good thing about making a lot of clocks is that after a while, writing the code become a bunch of cutting and pasting. The code for this clock closely mirrors that of both of my nixie clocks as well as my LCD clock. I just had to make a few small tweaks. After about two hours, I had all the code written for the time mode, date mode, and alarm mode. Read More...

VFD AC Filament Driver


blogEntryTopper
If you remember my last VFD clock, I attempted to design an AC filament driver for the display. I searched online for a solution and discovered the LM9022 VFD Filament Driver. Like the name suggests, it's specifically design to supply an AC signal to VFD filament from a DC source. It seemed too good to be true. Read More...

Large VFD Clock - Part I

When I set out to make my last VFD clock, I decided to drive the tubes with a MAX6921 chip. However, I couldn't for the life of me figure it out. I looked at a bunch of other projects online and tried to reverse engineer them, but I just couldn't get that chip to do anything. In the end, I gave up and decided to just drive the whole thing with transistors. With a new, more complicated clock in the works, it's time to figure out this chip. Read More...

IN-19 Nixie Thing


blogEntryTopper
While waiting for the paint to dry on my IN-14 Nixie Clock, I decided to tinker around with a small board idea to do something with this lonely IN-19 that I have. When I bought the IN-14s for my clock, the eBay seller threw one in as a way to make up for a delay in shipping. It's a cool little tube. But what would I ever use it for? Read More...

VFD Breakouts


blogEntryTopper
In order to start prototyping with my new VFDs, I need to make some breakout boards for them. Experience tells me that there's no easy way to jam them into a breadboard. Read More...

More VFDs!!!


blogEntryTopper
I just put the wraps on my last clock, the IN-14 Nixie Clock, and I already can't wait to start another one! I found some really huge ILC1-1/8L 7-segment VFDs on eBay. They're almost 4" tall. The digits themselves are 2.25" tall. Massive! Read More...

Nixie Clock V2 - Part III


blogEntryTopper
I'm really happy with the way that this clock came out. It's so much nicer than my IN-12 clock. I can't wait to get started on another one! Read More...

Nixie Clock V2 - Part II

blogEntryTopper
This clock is coming along nicely. I know I designed it a few months ago, but I shelved it for a month to wrap other things up. Now that I've decided to go ahead with it, it's been less than a month and it's almost complete! Read More...

My First 4 x 4 Speed Cube


blogEntryTopper
My son wants to get into speedcubing too. I picked up a 2x2 and a 3x3 for him. I wasn't going to buy myself anything, but I just couldn't resist picking up a 4x4 while I was at it. Read More...

Nixie Clock V2 - Part I


blogEntryTopper
I left off last time with the notion that I'd be able to create a new IN-14-nixie clock based off the design that I used for my IN-12 nixie clock. The plan was to use the main controller board as-is, and combine the driver and display boards. This proved to be more difficult than I had anticipated. The routing of the high voltage traces left much to be desired, simply due to the lack of real estate. I decided to not only use the original controller board, but the driver board too. After all, OSH Park gives you three boards for each order, so I have some left over from the last clock. I might as well use them up. Read More...
