Looking for awesome birthday gift ideas for guys? Look, we’re not saying Grandad’s garden shed provides the latest in home styling inspiration, but you have to admit this retro clock is a pretty good look for his bedroom or office. The brilliant vintage design appears to be an old-fashioned voltmeter, but instead one dial shows hours and the other minutes with a smooth analog motion. The aluminium housing features knobs for Time set, Calibrate Meter 1, Calibrate Meter 2, and “Twitchy Needle” display mode. Oh, and did we mention that it’s hackable too? The lock fuse on its Atmel ATtiny 24/44/84 family CPU is unset, making it the perfect gift for engineers and tinkerers alike.
