The top of the rotary encoder has been capped off with a sold metal knob, which combined with the enclosure made of stacked laser cut 3 mm acrylic sheets, really gives the device a very sleek and classy look. Put together on a piece of perfboard, the handwired circuit also includes an Adafruit PowerBoost 500 Charger, a 3.7 V 2500 mAh LiPo battery, a IS31F元731 Charlieplexed PWM LED driver, and a piezo buzzer. But you probably wouldn’t have been reading it about it here, so we won’t trouble ourselves with such thoughts. Were there better things he could have spent that time on? Possibly. Looking for something with a bit more style than the traditional kitchen timer, decided to take the last couple of months to design and build his own take on the idea using a rotary encoder, 16×9 LED matrix, and a Teensy 2.0 microcontroller. Posted in clock hacks, Microcontrollers Tagged 3D printed case, 7-segment display, atmega328p, kitchen timer, rotary encoder, TM1637 This Brutalist kitchen timer project is a nice addition to some of the kitchen timers we’ve featured in the past, including a minimalist LED matrix timer and a Nixie timer with keypad. It looks like the 3D printed case was sanded down to give it a smooth matte surface finish.Īll the project files, including the STLs, OpenSCAD code, and KiCAD design, are available on GitHub. ![]() On the back of the case is a power switch and USB-C connector for power. The internals are driven by an ATmega328P powered from a 18650 cell with a DW01-P battery protection chip and a TP4056 chip for charging. The case for ’s kitchen timer is 3D printed with openings for a TM1637 four digit, seven segment display and for a KY-040 rotary encoder with knob attached. ’s exploration of the idea is a clean, Brutalist kitchen timer. It helps you to keep track of cooking time, ensuring that your dishes are cooked evenly and accurately when making your favourite recipes.A kitchen timer is one of those projects that’s well defined enough to have a clear goal, but allows plenty of room for experimentation with functionality and aesthetics. Using a kitchen timer can make cooking and baking easier and more enjoyable. Rotary timers are simple and straightforward to use, while magnetic kitchen timers are great for busy kitchens as they can be easily attached to any metal surface. Other Salter kitchen timer models include mechanical rotary kitchen timers and magnetic kitchen timers. Digital kitchen timers are great for multitasking as they can be used to time multiple dishes at once. With a digital timer, you can easily set the countdown timer and be alerted when the time is up by an alarm sound or a flashing light. The most popular Salter kitchen timers are digital models, which are designed with easy-to-read LCD displays. Salter kitchen timers come in a variety of different styles and designs, making it easy to find the perfect timer for your kitchen. They can be useful for timing the boiling of eggs, boiling pasta or rice, and for making sure your food is cooked at the right temperature. Kitchen timers can be used with a wide range of cookware & kitchen appliances, including ovens & slow cookers as well as stovetop pots & pans. ![]()
