Smartphones can be multi-purpose portable devices that have compatibility in their pocket. But it’s rarely necessary to leave all the distractions of a smartphone and use a device that only fulfills a few responsibilities well. Some other people turn to “dumb phones” to communicate, while others use portable Android devices with less distracting screens to read without distractions.
The ePiPod, on the other hand, is a modern edition of a portable music player similar to the iPod. It’s a pocket-sized device for listening to music and not much else. Developer “Drhatch” built the ePiPod with a Raspberry Pi Zero 2 W as the brains and a small e-ink demonstration for the demonstration. Although you can rarely buy the ePiPod, you can find everything you want to create your own on a HackADay tasks page.
The task relies heavily on another DIY portable music player we talked about in 2018: the PiPod. The main differences are that the original model used a Raspberry Pi Zero and a 2. 2-inch LCD screen and 320 x 240 pixels. While the new model comes with a 2W Raspberry Pi Zero with increased processing power and wireless capabilities, and a 2. 13-inch LCD screen and 250 x 240 pixels. 122-pixel color-swapping e-ink display and a fast refresh rate to reduce power take-off and sun visibility.
Like the original Podd, the new edition of E Ink is a traditional PCB with a 24-bit DAC (digital-to-analog converter) and a 3. 5mm audio jack, a USB port for charging, and a microSD card for storage.
There are five buttons on the map to navigate menus and play music, volume buttons on the side and they all run a simple operating formula with VLC taking care of music playback tasks.
According to Drhatch, it was pretty straightforward to update the demo with a few tweaks because it uses the same SPI interface as the original. But Drhatch has made some software and hardware tweaks to expand the e-paper demo and increase battery life. For example, the ePod’s operating formula is based on the Raspberry Pi Bookworm Lite and the Raspberry Pi Zero 2 W has been set so that the processor now runs at 150 Mhz instead of 1 GHz by default.
While the original PiPod could run for about 2 hours on a 1200mAh battery, the EiPod has up to five hours of battery life.
