With a look inspired by old nixie tubes and with capacitors protruding through the surface like vacuum tubes, the Foxie Clock is a fun, colorful way to display the time at your desk, office, or anywhere. Brightness, color, animations, and time are all adjustable directly with 4 buttons on the back, with easier configuration via an iOS/Android app using Bluetooth in the near future.

#### What is it?

Welcome to the Foxie Clock, a fully open-source RGB clock with nixie-like edge-lit acrylic digits. Or... an RGB pixel display clock, if you like!

#### Why did you make it?
I love the idea of edge lighting. LEDs and edge lighting are a match made in heaven.

#### What makes it special?
It's retro and modern. Easy to hack. Want to make your own case? Do it. Make revisions to the design? Do it! Completely open source. The case (, PCB, firmware, and even the app (currently in the works) are all available at

  • Wood cases and PXL mode

    Will Fox08/18/2020 at 01:20 0 comments

    In the progress of working on the wood cases a few months ago, I quickly realized that I would need to either befriend a photographer or learn how to do it myself, otherwise it would be too slow and expensive to do anything. So, time well spent, I think.

    So, I've finally (sort of) launched the wood cases. I made several red oak cases, and I'm trying to clear those out before I start making more cases out of more exotic wood... so if anyone wants a 1-of-8 red oak wood case, now's the time.

    Finally, I've really tried to give the PXL mode the love it deserves. It's taken quite a bit of work and testing to get to the point where I'm ready to start shipping these. I love the PXL mode with the fading transitions between numbers. (Sorry, no video of this just yet... learning one thing at a time!) 

    I'm posting photos on FB and Instagram now, but here are a couple to look at before you head to :)

  • Lots of fun incoming for Foxie RGB pixel mode clock!

    Will Fox07/25/2020 at 17:57 1 comment

    One of the coolest things about the Foxie Clock is the versatility to be both an edge-lit display and a RGB pixel display. I haven't been able to put as much time into this project as I've wanted until now -- I'm full time Foxie Products!

    I've committed several improvements/fixes/features in the last 24 hours, and in addition to that, I've been working on making the "pixel mode" as good as the edge-lit mode... which needed some mechanical design work to get there.

    I designed a new "stand" that wraps around the existing 3d-printed case, and then use a "dark smoke" special acrylic for the cover, and I think it looks pretty fantastic! It does require a right-angle USB-C cable, which I will be providing with Foxie Clock orders that include this "stand"

    In addition, I also added an option that can "flip" the display, which works for both edge-lit and pixel display modes (see below picture)

    This new stand and the acrylic lid will start shipping with all Foxie Clocks soon, with a minor price increase (don't worry, you can still remove the stand/pixel lid if you don't care for it).

    P.S. I haven't forgotten about the wood cases or the app. It's been an absolutely ridiculous several months (outside of COVID-19), but I'm back on track now. More soon!

  • Foxie Clocks are shipping again!

    I'm now shipping Foxie Clocks again. Later this week, Wood Foxie Clocks will be available too.

    Stay safe, healthy, and Foxie!

  • More improvements coming!

    Will Fox03/29/2020 at 16:42 0 comments

    Like everyone, I'm at home adjusting to this new normal.

    I have had a list of things I wanted to improve some things for the Foxie Clock for some time now.

    1. Digit assembly sucks. I'm sorry. It just does. Peeling paper off 60 pieces of plastic is the worst.

    2. Digit thickness variance in the raw material has made the clocks less than perfect for some people. I'm sorry about this too. I tried to "fix" this as much as I could with the 3d-printed digit positioners, but they aren't the best fix possible.

    3. Even though 3D printed cases are awesome, I also really enjoy woodworking and I wanted to see how I can combine woodworking, 3d printing, and laser cutting.

    Let's tackle these one at a time. I've come up with a better design for cutting the digits that vastly improves assembly time by keeping them all attached as long as possible. It is possible to peel nearly all the plastic off the back of these in one shot, and due to improvements in the 0, 4, 6, 8, and 9, it is much easier to continue to peel up the plastic for these. In my experience, this reduces total digit peeling time by about 40 minutes, or more than 50%. One final change I will be making to this is to change the number order slightly to streamline assembly.

    Second, digit thickness variance and rigidity of the assembled digits. One of the things I tried was a narrow strip across the top of the digits:

    However, I really didn't like this for several reasons:

    - It makes it much more difficult to read the digits off-axis (that is, not directly from the front), which is one of my favorite parts of the clock. It is also prone to clouding up the digits, which is completely unacceptable.
    - It is a terrible idea to suggest super gluing at the top of the digits to people for assembly, due to badly clouding up the digits.

    So, I tried the "digit positioner" idea between 2 sets of digits again, but with clear acrylic and gluing them at the base (FAR less prone to clouding up the digits), and it was MUCH better. Unfortunately my first attempt made the "teeth" between the digits far too long.

    This made little bright rectangles at the bottom of every other digit when they're lit up! Not great. After further iteration and making the "teeth" much shorter, I came up with a design that holds the digits rigidly and doesn't add distracting rectangles. 

    So, all future clocks will ship with new clear acrylic digit positioners that are meant to be glued in place with a drop of superglue at the base of each digit. This also has the affect of permanently placing the digits in the lid after assembly.

    I also have decided to provide the option of pre-assembled sets of digits for the clocks for people that want to open the Foxing box and get Foxie as quickly as possible. That will be available in the near future.

    Finally, let's look at some exotic wood! (snicker) In the previous picture, I'm sure it was noticed that this was a different case design...

    Here is a close-up from the side:

    This is leopardwood, and looks incredible in person. It has various reflective bits, imperfections, and a ton of character, even after careful sanding. Also, this was the very first one I assembled and glued, and it isn't perfect either :) I've improved my assembly skills and 3d-printed (of course!) jigs since this case was created.

    I will be launching a new Wood Foxie Clock product line, using Solid Oak as the standard (but beautiful!) wood option. Cases made from exotic woods such as Leopardwood, Purpleheart, Padouk, and Wenge will also be available. These cases are for those that want to really want their clock to stand out. I'll also be offering custom laser engraving for your own message on the back of the case.

    Lastly, as indicated in the log a few weeks ago, the mobile app. It runs on both iOS and Android (8+) and is close to being ready to launch. I'm holding off on it for a bit for some further polish, but intend to launch it around the time I start shipping again.

    Thank you for reading and...

  • Foxie Progress!

    Wow, a project log entry?

    I'm getting pretty close to the launch of the app. I've uploaded a couple of pictures of it running on iOS and am doing further testing/development with Android this week, hoping to launch within the next 2 weeks.

    In other news, I'm also working on a new wood case design that should be quite a nice option for people not enthusiastic about the 3D printed cases.

I'm planning to add scheduled color/animation/brightness change capability to the clock sometime in March/April as I'm working on the app... I like setting the clock to dark red at night and restoring it to bright/cycle colors in the morning.

Will Fox wrote 02/19/2020 at 18:47 point

Thanks Ken! Yeah, everyone has different taste in colors. And brightness. I run mine on minimum brightness at night usually on the "cycle flow left" animation setting, and I've gotten used to it, even though I used to like to sleep in the dark :)

👍 I like the look of this. Finally a change from amber only nixies to any colour. But not blue in my bedroom.
