The instrument panel of a contemporary vehicle is ablaze with the glow of LCD shows. These fashionable, digital shows are much more versatile than the analog gauges and mechanical dials they’ve changed, however they’re additionally, nicely…boring. Flooring the accelerator of a muscle automobile simply isn’t the identical when the RPMs are proven on a glorified pill pc, fairly than the needle of a bodily gauge that’s wildly whipping into the pink zone.

David Forbes is an aficionado of basic automobiles who additionally has a penchant for all issues Nixie tube. Lately, he had the concept of mixing these two loves of his. So he outfitted his classic Volvo PV544 with a model new Nixie tube instrument panel that appears prefer it has been there because the automobile was manufactured. And technically, it might have been there—Nixie tubes existed at the moment.
The instrument panel could not have the ability to stream music or play video games like in a contemporary automobile, but it surely does almost all the pieces else. It shows engine RPM, automobile pace, battery voltage, complete mileage, coolant temperature, and oil stress—all within the superb pink glow of Nixie tubes.

To make this work, Forbes needed to introduce some fashionable tech. The prevailing, mechanical instrument interfaces had been linked to a customized circuit board. These inputs are interpreted by an onboard processing unit, which in flip drives the Nixie tubes, displaying acceptable measurements.
This isn’t essentially a simple construct; interfacing with outdated analog elements and dealing with the 200 volts required to drive the Nixie tubes complicates issues a superb deal. However with a 3D printer, a microcontroller, a handful of Nixie tubes, and a complete lot of endurance, it’s attainable. Try the main points on how Forbes made it occur to see if this challenge may also be best for you.
