The duct tape that holds everything together is the ultimate finishing touch as well, and we canвЂ™t really justify spending too much on fit and finish for a project that tosses itself around oneвЂ™s room. doesnвЂ™t really know why he had this idea, but itвЂ™s goofy and fun. When it does, it activates a small servo which knocks it off of its wall, rendering it unarguably useless. Powered by a small battery driving a Raspberry Pi, the single-board computer runs OpenCV and is programmed to recognize any face pointed in its general direction. ItвЂ™s difficult to tell if this clock was originally broken when he started this project, or if many rounds of checking the time have caused the clock to damage itself, but either way this project is an instant classic. But instead of simply powering itself off when turned on, this useless machine dislodges itself from its wall mount and falls to the ground anytime anyone looks at it. has followed this idea in spirit by putting an old clock he had to use with his take on a useless machine of sorts. Even though thereвЂ™s no real point, theyвЂ™re fun to build and to operate nonetheless. Useless machines are a fun class of devices which typically turn themselves off once they are switched on, hence their name.

It seems like everyone is making their own unique timekeeping device these days. If MakeTime outlives its time as a clock, all of the unused GPIO of the 328P are broken out to a single pin header, allowing it to be repurposed in other projects for years to come. To make the entire thing Arduino compatible, the microcontroller is an AtMega 328P, that can be connected to through the micro-USB port and CH340 USB-UART IC. designed the clock with hacking in mind, opting to build it with components that many are already familiar with, such as a DS3231 RTC and WS2812 LEDs. The second purpose is as a development platform. By using 24 LEDs, MakeTime achieves a timing granularity of 2.5 minutes. Rather than displaying the time with digits, MakeTime harkens back to round dial clocks by illuminating RGB LEDs along its perimeter to show the position of the minute and hour вЂњhandsвЂќ. MakeTime serves two purposes, the first and most obvious one is as a clock. is bringing the round face to digital clocks with his time-keeping piece, MakeTime. Most clocks these days have ditched the round face and instead prefer to tell time through the medium of 7-segment displays. But if you simply like your clocks with their electronics exposed, check out this free-form LED clock or this neat circuit sculpture clock.Д¬ontinue reading вЂњDrunk Wall Clock Uses Convoluted Circuits To Display TimeвЂќ в†’ Posted in clock hacks Tagged clock, ESP32, raspberry pi, vga We love projects like this that accomplish a simple task in a convoluted way, and thereвЂ™s no shortage of needlessly complicated clocks, whether physically drawing the time or using machine-learning data. Mounted on a round panel of recycled wood, it makes a beautiful wall ornament for any hacker lab. This fits well with the overall aesthetic of the clock, which consists of a heap of PCBs held together with cable ties and electrical tape. The clock got its вЂњdrunkвЂќ label because the process of repeatedly running the date command and parsing its output is slow and prone to hiccups, resulting in a display where the seconds advance in a somewhat unsteady manner. The resulting вЂњNTSCвЂќ signal is then fed into a small TFT display that shows the time. could have simply hooked up a VGA display to this, but instead went for another layer of complexity by converting the VGA signal to something resembling composite video, using nothing more than three resistors. This is a little PCB with an FPGA that emulates an OLED display and outputs the image to a VGA connector.

The вЂњFPGAвЂќ part is where it gets weirder: the ESP32 is hooked up to a VGA1306 board. It then telnets into the system, logs in, and requests the current time using the Linux date command. That mouthful is an accurate description of what it does: at the heart of the device is an ESP32 that uses WiFi to connect to a Raspberry Pi. Here at Hackaday we can never get enough of odd clocks, and weвЂ™re delighted to see вЂ™s creation called the Wifi-Telnet-FPGA-NTSC Drunk Wall Clock.
