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.

3D Printing is Awesome!

After waiting a few extra days, my patience was rewarded with the delivery of 3 rolls of filament. I think I've gotten the hang of PLA, but as far as ABS goes, I'm going to quit while I'm ahead. Read More...

Finally got a 3D printer!

After many, many years of putting off the purchase of a 3D printer, I finally bit the bullet. My wife ordered one for me and had it shipped overnight so that I'd have it for the 3-day holiday weekend! Read More...

Drobo Upgrade - WD Red Drives

blogEntryTopper
The other night I noticed that Time Machine failed to complete a backup to my Drobo. There was some weird error about the Drobo being set to read-only. I fixed it, but it reminded me that I had an old 640 and 750 Gig drive in there that needed to be upgraded.

GPS Clock Assembly, Part III

blogEntryTopper
I've been working on this clock for a long time, and a lot of effort has been put into it. I've learned so much from this project. I do have to admit some parts of the code aren't as elegant as they should be, but it works. With the code complete, all that's left to do is try my hand at designing a 3D printed joystick for the 5-way switch. Read More...

GPS Clock Assembly, Part II

blogEntryTopper
If you’re following along, you know that version 1.0 of my GPS clock was a total bust. I somehow managed to screw up the PCB. I had the FTDI RX and TX lines tied to the wrong port on the ATmega2560. There was just no way to rework the board. Besides, I like to keep my final projects looking neat and clean. Rework wires are just a big no-no in my book. That meant that I had to fix the error on the PCB and place another order. I got my boards and most of my parts. I soldered together what I could. So far, it looks like it’s going to work!

128x64 LCD Teardown

I don’t know what I’ll do with it, but it’s better than just throwing it out. Maybe it’ll come in handy one day. Just remember, never throw anything away unless you’ve torn it apart first! Read More...

Arduino as ISP Shield

blogEntryTopper
Many a time have I had to set up my Arduino UNO as an ISP in order to burn the bootloader to either another Arduino or an SMD project. It’s a pain every time having to look up the pinouts and construct a cable each time. Having a shield is so much easier than messing around with jumper wires and DIY homebrew cables.

More Nixie Tube Experiments

blogEntryTopper
Moving right along with the nixie tube experiments... I decided to add a 74595 shift register into the mix and attempt to shift out some data to two of my nixie breakout boards through a 74141 nixie driver.

Driving a Nixie with a 74141 BCD Decoder

blogEntryTopper
In order to drive a nixie, you can use a 74141 BCD decoder. Sure, you can use transistors, but you’ll need a bunch of them. You can drive all 10 nixie segments off one 74141 chip. All you have to do is feed it a number in binary and the chip lights up the corresponding cathode on the nixie; the same way you’d drive a 7-segment display with a 74247. Read More...

IN-12 Nixie Breakout Board, Part 2

blogEntryTopper
Rev 1 of my IN-12 Nixie Breakout Board was an abomination. Upon realizing that the nixie footprint that I used for the PCB was completely wrong, I immediately re-spun the board. I got it right this time. All ten digits light up when the corresponding pin is grounded on the 10-pin header. Read More...
