The instrument panel of a contemporary vehicle is ablaze with the glow of LCD shows. These trendy, 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 automotive simply isn’t the identical when the RPMs are proven on a glorified pill laptop, quite than the needle of a bodily gauge that’s wildly whipping into the crimson zone.

David Forbes is an aficionado of traditional vehicles who additionally has a penchant for all issues Nixie tube. Just lately, he had the thought 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 automotive was manufactured. And technically, it might have been there—Nixie tubes existed at the moment.
The instrument panel could not be capable of stream music or play video games like in a contemporary automobile, but it surely does almost every little thing else. It shows engine RPM, automobile pace, battery voltage, complete mileage, coolant temperature, and oil stress—all within the wonderful crimson glow of Nixie tubes.

To make this work, Forbes needed to introduce some trendy tech. The present, 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 applicable measurements.
This isn’t essentially a straightforward construct; interfacing with previous analog parts and dealing with the 200 volts required to drive the Nixie tubes complicates issues an excellent deal. However with a 3D printer, a microcontroller, a handful of Nixie tubes, and an entire lot of endurance, it’s attainable. Try the main points on how Forbes made it occur to see if this venture may additionally be best for you.
