A particularly popular type simply puts some keyboard switches on a plate to provide a certain type of clicky satisfaction. [wjddnjsdnd] took that concept a step further, building a keychain-sized fidget toy <a href="https://www.instructables.com/GameBox-Clicker/" target="_blank">that actually has games on it.</a></p>

The key switches are notable in this case for being magnetic shaft keys. Rather than using a mechanical switch to indicate a keypress, the keycap instead merely moves a magnet which triggers a signal in a hall effect sensor beneath the key. In this case, the build uses A3144 hall effect sensors, which are read by the Arduino Nano running the show. The Nano is also hooked up to a small SSD1306 OLED display over I2c, which it uses for displaying the game state. There’s also a TP4056 module to handle charging the attached 380 mAh

Comparing a Clone Raspberry Pi Pico 2 With an Original One

<div><img alt="" class="attachment-large size-large wp-post-image" height="625" src="https://hackaday.com/wp-content/uploads/2026/01/raspberry_pi_pico_2_clone_comparison_pfister_blog.jpg?w=732" style="margin: 0 auto; margin-bottom: 15px;" width="732" /></div><p>Although [Thomas] really likes the Raspberry Pi Pico 2 and the RP2350 MCU, he absolutely, totally, really doesn’t like the micro-USB connector on it. Hence he jumped on the opportunity to source a Pico 2 clone board with the same MCU but with a USB-C connector from AliExpress. After receiving the new board, he set about <a href="https://pfister.dev/blog/2026/pico2-clone.html" target="_blank">comparing the two</a> to see whether the clone board was worth it after all. In the <a href="https://www.youtube.com/watch?v=MxgPmbocAF4" target="_blank">accompanying video</a> you can get even more details on why you should avoid this particular clone board.</p>
<p>In the video the respective components of both boards are analyzed and compared to see how they stack up. The worst issues with the clone Pico 2 board are an improper USB trace impedance at 130 Ω with also a cut ground plane below it that won’t do signal integrity any favors.</p>
<p>There is also an issue with the buck converter routing for the RP2350 with an unconnected pin (VREG_FB) despite the recommended layout in the RP2350 datasheet. Power supply issues continue with the used LN3440 DC-DC converter which can source 800 mA instead of the 1A of the Pico

ESP8266 (and ESP32)

These little modules have taken hobby electronics by storm, so of course I grabbed a few of them and have been hacking away quietly on both the ESP8266 and the ESP32.(...)

Forever will stubbornly say "eye too see", not "eye squared see".

I get it, and sure, that's great, but no. Can't make me do it.
