"If you are searching for an affordable Nixie tube clock you may be interested in the Nixie Tap"

Hackster News

"Unlike many Nixie tube clocks that aim for an elaborate steampunk or cyberpunk style, Nixie Tap is as minimalist as it gets... But Nixie Tap isn’t just a pretty face, it is also WiFi-connected and has a number of functions thanks to a built-in ESP8266."

"Außerdem ihnen stecken noch ein ESP8266, ein Erschütterungssensor und ein USB-Anschluss in dem schicken Kästchen. Das Open-Source-Gerät kann damit als "Schalter" in zahlreiche eigene Projekte integriert und umprogrammiert werden."

Nixie Tap is part of the Microchip Get Launched 2019 design competition!

A Nixie Clock as Beautiful as it is Functional

Nixie Tap is a compact, no-frills Nixie clock. It's powered via a micro USB connector, so that you can power it via any USB port or old phone charger. It also has Wi-Fi, so it can automatically synchronize with an NTP time server once connected to a wireless network.

We made the Nixie Tap to look good on our desks, and hopefully, it will look good on yours.

What is a Nixie Tube?

Nixie tubes are an early form of display technology from the Cold War era. Designed for military and scientific use, these tubes are now harder to come by. We've worked hard to make Nixie Tap a worthy home for these ever-more-scarce tubes.

An Attractive Open Source Option

There is something magical about Nixie tubes. Watching digits and dots change almost has a meditative effect, and it keeps your eyes glued to the orange numerals. As soon as we fired up the first digit, we knew we had to have an entire clock. We set out looking for a pre-existing kit or finished product. There were simple constraints:

  • It should be a finished product which blends into our living rooms
  • Its enclosure should be made of natural materials
  • It should be open source

Although there are countless Nixie clock kits, finding one that ticks all these boxes is not a simple task. For us, this was a clear call to action, and we decided it's time for such a Nixie clock to be brought to life.

Designed for Hackability

While Nixie Tap is a great clock, I've also made it easy and fun to hack on. To the extent possible, everything is open source, and the latest files can be found in the project repository.

IFTTT Integration

You can connect Nixie Tap to your IFTTT account it into an input device capable of triggering any of hundreds of events. Just give your Nixie Tap a gentle tap to kick off that Rube Goldberg IoT machine you've been dreaming of.

Easily Programmable ESP8266

The control center of the device is the beloved ESP8266. It coordinates the Wi-Fi, display (via SPI), real-time clock (via SPI), and tap sensor (via digital input) to make everything run smoothly. Arbitrary code can be uploaded from your choice of development environment using the same micro USB cable that supplies power (included).

Custom USB Nixie Power Supply

Special care was taken to ensure that the unit runs from 5 V from a standard USB port. Initially, the prototypes used a power supply unit (PSU) bought off of eBay, which were hard to get and proprietary. So, we decided to design our own PSU, and ended up with one of the first open source, high-efficiency USB Nixie PSU designs. We hope other people use it in their own projects!

Warm Walnut or Cold Metal

To keep the premium look that Nixie tubes themselves have, we designed the enclosure around traditional materials: walnut and aluminum.

Walnut

Before the final version, we tested a few types of hardwoods (walnut, mahogany, wenge). Each of these had its own characteristic pattern, and we ultimately chose walnut, as it gave the most consistent pattern quality. The enclosure is machined from a single block of walnut, and finished using oil.

Aluminum

For those of us who like metal, we prepared a special version. This one is heavy, cold, and black. It's machined from a single block of aluminum, and anodized in black.

Enclosure 3D Model

Setup & Modes of Operation

On first power-up, Nixie Tap will serve a hotspot called NixieTap. Within this hotspot, you can manually override the time and date, set keys for IFTTT integration, and enable or disable operating modes.

By default, the unit has four modes of operation:

  • Time
  • Date
  • Temperature
  • Cryptocurrency price

To change between the modes, just gently tap the Nixie Tap. Each mode can be turned on or off by accessing the Setup menu.

Manufacturing Plan

We're putting the final touches on Nixie Tap. As it stands right now, it is fully operational. In fact, you can produce it yourself using the files from the project repository. If this Crowd Supply campaign meets its funding goal, here's what we'll do next:

  1. Build Production Validation Test (PVT) Prototype: To make Nixie Tap just right, we'll spend some time polishing everything before entering production.
  2. Enter Full Production: In this phase, our subcontractor orders components and assembles all the electronics. Afterwards, we individually assemble and test each unit to make sure you get a premium product.
  3. Ship to Backers: After we make sure your units are perfect, we'll ship them to the Crowd Supply warehouse, and then they'll be shipped to you.

Shipping & Fulfillment

Nixie Taps will be shipped to backers using Crowd Supply's fulfillment service, so parcels will be shipped to backers from their warehouse in the USA. Delivery within the US is free. Delivery outside the US will incur a surcharge during checkout. For more information, please see Crowd Supply’s guide on ordering, paying, and shipping.

Risks & Challenges

As Nixie Tap is a relatively stable product, the primary challenge is in scaling production. What worked for fewer than ten pieces may not work for 100 pieces. To reduce risk, we use experience from our day jobs, and rely on the same proven supply chain. Any deviation from the plan will be communicated in advance.
