  • Automating Pool Monitoring And Chemical Dosing | Hackaday

    The project uses a TI SimpleLink wireless-enabled microcontroller to run the show, which allows data to be offloaded to a base station for graphing with Grafana. The system can monitor pH levels as well as ORP (oxidation/reduction potential) levels using probes attached via BNC connectors. Based on these readings, the device can dose chlorine into the pool as needed using a peristaltic pump driven by a TI DRV8426 stepper motor driver.

  • $99 Lepton FS module cuts the cost of FLIR thermal cameras by half - CNX Software

    Thermal cameras based on FLIR Lepton modules are pretty cool, but also quite expensive. Teledyne FLIR Lepton FS offers a much more cost-effective solution with the non-radiometric 160 x 120 resolution micro thermal camera module going for $99, or about 50% less than other FLIR thermal camera modules.

    The lower cost was achieved with some tradeoffs, notably a reduction of thermal sensitivity and scene dynamic range, as well as up to 3% inoperable pixels. But Ron Justin, GroupGets founder, told CNX Software that the lower specs are more than worth it for users only needing an imager, as opposed to a radiometric sensor.

  • Raspberry Pi Weekly Issue #374 - Raspberry Pi <3 LEGO Education

  • Bring That Old Hi-Fi Into The 2020s | Hackaday

    It’s a distressing moment for some of us, when a formerly prized piece of electronic equipment reaches a point of obsolescence that we consider jettisoning it. [Jon Robinson] ran into this dilemma by finding the Kenwood Hi-Fi amplifier his 17-year-old self had spent his savings on. It was a very good amp back in the day, but over two decades later, it’s no longer an object of desire in a world of soundbars and streaming music boxes. After a earlier upgrade involving an Arduino to auto-power it he’s now given it an ESP32 and an i2S codec which performs the task of digital audio streaming as well as a better job than the Arduino of controlling the power.

  • This Arduino Terminal Does All The Characters | Hackaday

    The job of a dumb terminal was originally to be a continuation of that performed by a paper teletype, to send text from its keyboard and display any it receives on its screen. But as the demands of computer systems extended beyond what mere ASCII could offer, their capabilities were extended with extra characters and graphical extensions whose descendants we see in today’s Unicode character sets and thus even in all those emojis on your mobile phone. Thus a fully-featured terminal has a host of semigraphics characters from which surprisingly non-textual output can be created. It’s something [Michael Rule] has done some work on, with his ILI9341TTY, a USB serial terminal monitor using an Arduino Uno and an ILI9341 LCD module that supports as many of the extended characters as possible.

Hardware

RaspberryIn a recent episode of our weekly Raspberry Pi podcast, The PiCast, we had the honor of featuring developer and Artist Geeky Faye Art who’s been hard at work creating a huge BMO figure, a character from the show Adventure Time, with a Raspberry Pi inside. According to Geeky Faye Art, the goal of this project is to create a figure that looks like BMO, talks like BMO, and runs OctoPrint, an open-source system developed just for the Raspberry Pi to help manage and control 3D printers.

Inside BMO, you’ll find a Raspberry Pi with a dedicated screen where BMO’s face usually is. A speaker is mounted inside the body for audio output. A custom PCB was developed to make the front-facing buttons functional. These buttons look just like the originals found on BMO and are printed using PLA filament.

The Coolest Raspberry Pi Projects You'll Find

Filed under
Hardware

When it comes to DIY maker technology, few bits of hardware have had the versatility and outright longevity of the Raspberry Pi. Launched in 2012, the Raspberry Pi is a silent, energy-efficient, single-board computer that fits inside the palm of your hand—or inside just about anything you might want to make computer-controlled.

The Pi planet has seen four main releases of Raspberry Pi boards, along with various mods and variants, over the last decade, with the Raspberry Pi 4 Model B the latest and greatest revision. (That will stand, at least, until the Raspberry Pi Foundation reveals the next rumored Pi model in 2022 or 2023.)

Some of the older pre-Pi 4 models, though, are still available for less than the cost of an entrée at your local diner, and the creativity they have spawned is near limitless. Let’s take a look at some of the best Raspberry Pi projects we’ve seen in 2021.

Hardware

This explanation article is for beginners in The Free Software and GNU/Linux Community. You will certainly meet terms like amd64, i386, and ppc64el as choices when getting copy of a software or an operating system. In short, these terms refer to choices of computer's CPU products (also known as processors) which would determine choices of software and operating systems that you can run on it. In practice, knowing these terms may benefit you to select correctly software and operating systems for your computer. Now let's start learning!

Most PCs and laptops today are amd64. Most PCs and laptops produced in 1990's and before 2011 are i386. Several latest technology computers aimed for the future and could be replacing amd64 and i386 produced as ppc64el. For example, PCs with Intel Pentium 4 or AMD Althlon Classic are all i386 (also known as PC 32-bit) while today PCs with Intel Core 2 Duo and AMD Phenom onwards are all amd64 (also known as PC 64-bit).

  • An Open Source Game Boy Printer That Doesn’t Print | Hackaday

    While we’ll admit seeing your Game Boy Camera shots come out on a little slip of thermal paper was pretty neat back in 1998, anyone who’s still using the Game Boy Printer these days is probably more interested in getting their images in digital form. Which is why the open source NeoGB Printer is so exciting.

    A collaborative effort between [Rafael Zenaro], [Raphaël BOICHOT], and [Brian Khuu], the project combines an ESP32 development board and some common components with their GPLv3 firmware to fully emulate the Game Boy Printer hardware. Once plugged into your Game Boy, any of the 110 titles that support Nintendo’s paper-pushing peripheral will recognize the NeoGB Printer as the real deal and happily send along the image.

  • Mapping Dance syncs movement and stage lighting using tinyML | Arduino Blog

    Being able to add dynamic lighting and images that can synchronize with a dancer is important to many performances, which rely on both music and visual effects to create the show. Eduardo Padrón aimed to do exactly that by monitoring a performer’s moves with an accelerometer and triggering the appropriate AV experience based on the recognized movement.

    Padrón’s system is designed around a Raspberry Pi 4 running an MQTT server for communication with auxiliary IoT boards. Movement data was collected via a Nano 33 BLE Sense and its onboard accelerometer to gather information and send it to a Google Colab environment. From here, a model was trained on these samples for 600 epochs, achieving an accuracy of around 91%. After deploying this model onto the Arduino, he was able to output the correct gesture over USB where it interacts with the running Python script. Once the gesture is received, the MQTT server publishes the message to any client devices such as an ESP8266 for lighting and plays an associated video or sound.

  • This tinyML device counts your squats while you focus on your form | Arduino Blog

    Getting in your daily exercise is vital to living a healthy life and having proper form when squatting can go a long way towards achieving that goal without causing joint pain from doing them incorrectly. The Squats Counter is a device worn around the thigh that utilizes machine learning and TensorFlow Lite to automatically track the user’s form and count how many squats have been performed.

    Creator Manas Pange started his project by flashing the tf4micro-moition-kit code to a Nano 33 BLE Sense, which features an onboard three-axis accelerometer. From there, he opened the Tiny Motion Trainer Experiment by Google that connects to the Arduino over Bluetooth and captures many successive samples of motion. After gathering enough proper and improper form samples, Manas trained, tested, and deployed the resulting model to the board.

Raspberry Pi Tablet Gets Radio Surgical Enhancement

Hardware

We always get excited when we buy a new tablet. But after a few months, it usually winds up at the bottom of a pile of papers on the credenza, a victim of not being as powerful as our desktop computers and not being as convenient as our phones. However, if you don’t mind a thick tablet, you can get the RasPad enclosure to fit around your own Raspberry Pi so it can be used as a tablet. Honestly, we weren’t that impressed until we saw [RTL-SDR] add an SDR dongle inside the case, making it a very portable Raspberry Pi SDR platform.

The box is a little interesting by itself, although be warned it costs over $200. For that price you get an LCD and driver board, a battery system, speakers, and an SD extension slot with some control buttons for volume and brightness. There’s a video of the whole setup (in German) below.
