This is just a quick heads up video, The Raspberry Pi Foundation just released the all-new Raspberry Pi 400 Personal Computer Kit and it looks amazing! Powered by the same BCM 2711 CPU that comes in the Raspberry Pi4 but it’s clocked at 1.8Ghz out of the box as opposed to 1.5Ghz! It also has 4GB of ram 2x USB 3.0 ports 1x USB 2.0 AC wifi and full access to the GPIO and it will run basically any OS that the pi 4 can but it comes with a 16Gb Micro SD card pre-loaded with Raspberry Pi OS.
This is something that Raspberry pi has never done and I’m looking forward to testing out the Pi 400 soon.

How to use millis() function to multitask in arduino code.
In this video I am looking at using millis function in the code. Describing the advantages it has over using delay function. This video is also introducing the concept of multitasking in Arduino code.
Minimal metal detector made with an Arduino and a coil of wire
For an easy DIY metal detector setup, look no further than this project by creator “rgco.”
The handheld device uses a 20-60 turn coil of 26AWG enameled wire, connected across an Arduino Uno or Nano’s pins 8 and 10. A series of pulses is continuously sent out by pin 10, which are delayed in reaching pin 8 according to the inductance across the coil. As this coil approaches other metallic objects, the effective inductance changes, thus varying the delay in the signal reaching pin 10.
This effect is sensed by the Arduino, outputting chirps on a buzzer as audio feedback when metal is nearby. To convert it into a practical device, the Nano configuration is stuffed into a Tic Tac container, with the coil held at a distance with two skewer sticks.
A Massive Upgrade Makes the Classic Super Nintendo Super Scope Work on Modern TVs
Despite a renaissance in outdated gaming tech, there’s a small blip in the history of retro gaming hardware that has all been all but abandoned in the emulation scene: light guns. The way the technology worked simply isn’t compatible with modern TVs and screens, so if you want to get something like the Super Nintendo’s Super Scope working again, you either need to find an old tube TV, or perform a monumental hack on the hardware like Andy West did.

AM/FM/SW Radio Receiver – Si4730 / Si4735
This Arduino radio receiver has an attractive look and nice features using an inexpensive color TFT / Arduino and fell componets.
It includes the indication of the frequency in large numbers in the style of vintage seven segments, two bargraphs for indicating the signal strength, selection of 7 BW filters for AM, indication of the wavelength of the band, 2 color themes, Stereo/Mono indication and 14 bands for coverage of LW / MW / SW / CB, ranging from 100kHz to 30MHz and the commercial 64-108MHz FM band.
