Jürgen from NixieKits.eu is working on a new design for a line level preamplifier. This new device will have the same footprint as his headphone amp and he has been kind enough to share the schematics so far. The cool part of this design is that will support a range of tube with both 6v and 12v filaments. For example the ECC81 / 82 / 83 (12Ax7) have a 12V filament. All "newer" tubes, e.g. ECC88 / E802CC... and all Russian types (6N1P...) have a 6V filament.
Paraphrased from the seller: This is a hand crafted, radio controlled clock. Each clock is one of a kind and only the highest quality components are used. The buyer may customize the clock with any LED color or size of their choice.
One of the things that this website doesn't have enough of is CRT / Oscilloscope clocks. Thankfully, I found an eBay seller who is happy to help fill the void. eBay seller al-truism has been selling scope clocks for a while and I've been watching them as his designs progress and he is offering them pretty regularly via eBay and directly from his website. For those who are a little more adventurous, he sells the board directly as a kit. His website has lots of great work and his YouTube channel shows the devices in action - go check it out.
From his site:
These oscilloscope clocks display a digital face for ten seconds and then an analog face for ten seconds. This helps to reduce the "burn-in" that otherwise will inevitably occur on crts displaying the same image for too long. Many of the parts are recycled from used electronics, which makes them kind of "green". The base and shroud are homemade from plexiglass. These scope clocks have a "shifter" that will move the display on the screen slightly every 6 seconds. Also , the display alternates every ten seconds between analog and digital face. This helps to greatly reduce the burn in that can result from the display staying in the same spot continuously. The Nixie clocks are "faders", which means when the numbers are changing, the number that's going is dimmed while the number that's coming is brightened. This produces a "morphing" effect that kind of makes them appear to melt into the next one. The oscilloscope clocks are user programmable with preset sleep / wake mode , which will turn the display on and off at preset times automatically, while still keeping time, thus conserving the crt usage and extending its lifespan.
Here is a cool 4 digit numitron clock based off of what appears to be an ardunio. Based on the GitHub description:
Good news, the USB powered Magic Eye Winker from NixieKits.eu is finished! It is based on the same dimensions as the tube board from the Magic Eye VU-Meter (50 mm diameter) this gadget does only one thing: "Winking".
It is powered via USB * and all 6V heater tubes can be fitted. Solder bridges on the bottom side will connect the signals according to the socket needed for the tube.
These tubes can be fitted:
EM80 / EM81 / EM84 / PM84 / EM85 / EM87 / EM800 / EAM86 / 6BR5 / 6DA5 / 6E2 / 6E3P / 4FG6 / 6FG6 / 6DH7 / 6HU6
* it can also be powered from an external battery pack up to 18V, so it is possible to fit tubes with different heater voltages like the UM80 with 19V for example

The TubeClockDB / Tube Clock Database is a collection of nixie clocks, vfd clocks, vacuum fluorescent clocks, crt clocks, scope clocks and oscilloscope clocks. We will feature just about anything: fully assembled clocks ready to purchase, kits, or even individual nixie tubes.
