The 2025 One-Hertz Challenge is here, and it’s officially the year when your beloved ZX Spectrum has graduated from gaming nostalgia to a Z80 frequency counter! Who knew that all those hours spent trying to save Princess Lolly would lead to… well, counting hertz? Talk about a glow-up! From pixelated adventures to measuring frequencies—because why not? I can already hear the cries of “But where's the fun in that?” echoed from basements worldwide. So, dust off that black plastic box, friends. It's time to embrace the thrilling world of electrical oscillation. Who needs games when you can have a vintage calculator? #ZXSpectrum #OneHertzChallenge #TechNostalgia #FrequencyCounter #GamingEvolution
