Making an audio frequency counter using an RP2040

The AUDIODiWHY blog wanted to build a clock multiplier for the bench, but needed a way to accurately read frequencies of incoming signals. Between 10hz and 100K.

The firmware for the reader is based on a cool RP2040 counting algo by Jeremy P. Bentham–see his blog post here and github page here.

I modified it a little, but not much, and made it display observed frequencies on a small OLED display using David Schram’s open source C library for SSD1306’s: here.

A few minor code changes were needed, for instance, the frequency reading algorithm put the frequency value into an integer in memory, but for the  Schram1306 library I needed a string.

Check out how it was done in the post here.

I am using AI to automatically drop hats onto New Yorkers @j_stonemountain

James Steinberg on dropofahat.zone writes:

I am a simple midwesterner living in the middle of New York City. I put my shoes on one at a time, I apologize when I bump into people on the street, and I use AI inference to drop hats on heads when they stand outside my apartment. Like anybody else.

I have extremely high foot traffic outside my window. I see a sea of uncovered heads in the sun. I believe DropofaHat.zone will become the first of many window based stores. Here a busy New Yorker can book a 5 minute time slot, pay for a hat, stand in a spot under my window for 3 seconds, have a hat put on their head, and get on with their extremely important, extremely busy day all within a single New York minute.

As far as the mechanism used:

The Dropping Mechanism was the simplest thing to get working. I had a Raspberry Pi and an stepper motor lying around so I decided to put them to work.

I literally copied code out of an Adafruit tutorial for the stepper motor. This is a single Python file on the Raspberry Pi that the computer will run when the AI determines someone is standing in the right spot and ready to receive their hat.

Benchmarking TensorFlow and TensorFlow Lite on Raspberry Pi 5 #piday #raspberrypi

Alasdair Allan has done some solid work over the past years benchmarking machine learning accelerator hardware. Now he turns his attention to the Rasperry Pi 5 on Hackster.io:

Running the benchmarks on the new Raspberry Pi 5 we see significant improvements in inferencing speed, with full TensorFlow models running almost ×5 faster than on they did on Raspberry Pi 4. We see a similar increase in inferencing speed when using TensorFlow Lite, with models again running almost ×5 faster than on the Raspberry Pi 4.

This roof-mounted Raspberry Pi tracks flights and photographs the aurora borealis

Ashley Whittaker shared this project on Raspberrypi.org

An Alaska-based maker sees your flight tracker and raises you with a two-for-one: a flight-tracking, aurora borealis-photographing, roof-mounted setup.

A Raspberry Pi 4 wearing a PoE HAT is the brains of the operation, while a Raspberry Pi High Quality Camera wearing a fisheye lens looks up and captures amazing light shows in the Alaskan night sky. Raspberry Pi-compatible sensors for radio and for visible light tell the camera when to kick in and start photographing the sky.

Feather of the Day: Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier #Adafruit #Feather #PiDay

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit RP2040 Prop-Maker Feather with I2S Audio Amplifier!

The Adafruit RP2040 Prop-Maker Feather: an all-in-one combination of the Feather RP2040 with a Prop-Maker FeatherWing with a few tweaks based on feedback from expert prop-builders. Perfect for fitting into your next prop build! This Feather will unlock the ‘Imagineer’ inside all of us, with tons of stuff packed in to make sabers & swords, props, toys, mini robots, cosplay pieces, and more.

We looked at hundreds of prop builds, and thought about what would make for a great low-cost (but well-designed) add-on for our Feather boards. Here’s what we came up with:

• Terminal Block NeoPixel Port – With easy-to-use screw terminals you can quickly connect and disconnect your NeoPixel strips and rings. This port provides high current drive from either the Feather Lipoly or USB port, whichever is higher. A 5V level up-shifter gives you a clean voltage signal to reduce glitchiness no matter what LED chip you’re using. You can also cut power to the entire strip instantly to reduce quiescent power, thanks to a separate control transistor. Works with any and all NeoPixels (SK6812 / WS2812 family)
• MAX98357 I2S 3 Watt Class D Audio Amplifier – Drive any 4-8Ω speaker, up to 3 Watts, for sound effects. Audio comes out on two of the terminal blocks so you can screw in any wires to a speaker you like – we’re partial to this small 3W speaker or this enclosed style 3W speaker, both come with pre-attached wires. Thanks to the I2S digital inputs, you’ll get excellent audio quality
• Triple-Axis Accelerometer with Tap Detection – The LIS3DH is our favorite accelerometer, you can use this for detection motion, tilt, or taps. Here’s an example of a lightsaber that makes sounds when swung or hit. We have code for this chip in both Arduino and CircuitPython.
• Extra Button or Output Pin – One more pin on the terminal screw block can be used for button input or digital output, for activation or a simple LED.
  Servo Connection – Plug any hobby servo with 3 wires into the 0.1″ spaced header, and you can have quick motion control.
• Low power mode! The power system for the NeoPixels and speaker amplifier can be controlled by a pin to cut power to them, so you have lower power usage when the prop is in sleep or off mode (but can wake up fast by listening to the button press or accelerometer data).
• At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8 MB of onboard QSPI FLASH and 264K of RAM! There’s even a STEMMA QT connector for plug-and-play of I2C devices.

Making faux stained glass LED art for denim wearables

GeekMomProjects shows a work in progress: an LED stained glass type design that will adorn the back of a denim jacket.

The LEDs were diffused with hot glue!

Hot gluing in progress. It looks super janky from the back but hot glue works better for diffusing the LEDs inside the 3D printed shells than any other medium I’ve tried. The industrial size hot glue gun was a worthwhile purchase!

Google and Harvard Team Up to Make the Most Detailed Map of Human Brain Ever #ArtTuesday

The mapped complexities of the human brain paint a pretty picture. Based on 1.4 petabytes of raw data, google scientists of mapped a cubic millimeter of the human brain. Originally published by Nature picked up by My Modern Met:

The human brain is one of the most significant objects in the world, and also one of the most complex. Yet that three pounds of tissue that mediates every moment of our lives, every decision, every reflex, every emotion, is essentially still a mystery to scientists. A recent joint effort by Harvard and Google research teams has extracted an incredible amount of data from just 3 mm of brain tissue. With machine-learning modeling, the team created the world’s highest-resolution brain tissue map. This brain map lets researchers see 57,000 cells and 150 million synapses, which are connections between the neurons.

MicroMac, a Macintosh for under £5 on a Raspberry Pi Pico

Matt Evans writes:

This all started from a conversation about the RP2040 MCU, and building a simple desktop/GUI for it. I’d made a comment along the lines of “or, just run some old OS”, and it got me thinking about the original Macintosh 128.

The £3.80 RPi Pico microcontroller board: The RP2040’s 264KB of RAM gives a lot to play with after carving out the Mac’s 128KB – how cool would it be to do a quick hack, and play with a Mac on it?

A Raspberry Pi RP2040 microcontroller (on a Pico board), driving monochrome VGA video and taking USB keyboard/mouse input, emulating a Macintosh 128K computer and disc storage. The RP2040 has easily enough RAM to house the Mac’s memory, plus that of the emulator; it’s fast enough (with some tricks) to meet the performance of the real machine, has USB host capability, and the PIO department makes driving VGA video fairly uneventful (with some tricks). The basic Pico board’s 2MB of flash is plenty for a disc image with OS and software.

Desk of Ladyada – RP2040 Adalogger, C6 Feather, Floppy and some RS-232 #DeskOfLadyada #adafruit @adafruit

This week, we worked on some testers and a few small designs. First up is the RP2040 Adalogger Feather which worked first try, so we’re already on to the tester – using our classic RP2040 brains, we’re now able to get a tester going in under an hour.

Next, we’re circling back to our floppsy interface board: we wanted to stock some floppy drives but found that a bunch of the ones we ordered don’t have an index pulse, so we designed a little test sketch to let us know if we are able to read MFM sectors.

We’re also still testing the ESP32-C6 Feather. We love using a TFT FeatherWing because it lets us verify I2C and SPI functionality – we’re dilly-dallying a bit but hope to send these PCBs out in a week or two.

Finally, we designed an IR transceiver, updated HUSB238 Type C PD, and designed two RS232 level shifters!

And this week on The Great Search – Finding a pin-complete RS-232 transceiver

Setting up a Firewall on your Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi

In Dungeons and Dragons, a fire wall is a wall of fire create by a magic user as a defensive measure that can also cause damage. In software, a firewall is essential protection for your operating system. In the world of dining, a raspberry pie is a tasty fruit-filled pastry. In the world of Adafruit, we’re a done with this bit! Here’s an article on installing a firewall on your Raspberry Pi, via Pi My Life Up:

Setting up a firewall on your Raspberry Pi helps protect a bad actor from potentially causing issues on your device or accessing services you don’t want to be accessed.

Most Linux operating systems, such as Raspberry Pi OS, already have a firewall built into the kernel. This is controlled by the somewhat complicated nftables. Nftables allows complicated firewall routing, but for most users, it can be a bit daunting.

Feather of the Day: Adafruit Feather RP2040 CAN Bus Feather with MCP2515 CAN Controller #RP2040 #Adafruit #Feather

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit RP2040 CAN Bus Feather with MCP2515 CAN Controller – STEMMA QT!

If you’d like quickly get started with CAN bus interfacing, with no soldering required, our Adafruit RP2040 CAN Bus Feather comes ready-to-rock with a microcontroller, CAN chipset, and terminal blocks for instant gratification. The controller used is the MCP25625 (aka an MCP2515 with built-in transceiver), an extremely popular and well-supported chipset that has drivers in Arduino and CircuitPython and only requires an SPI port and two pins for chip-select and IRQ. Use it to send and receive messages in either standard or extended format at up to 1 Mbps.

Messages are sent at about 1 Mbps rate – you set the frequency for the bus and then all ‘joiners’ must match it, and have an address before the packet so that each node can listen in to messages just for it. New nodes can be attached easily because they just need to connect to the two data lines anywhere in the shared net. Each CAN device sends messages whenever it wants, and thanks to some clever data encoding, can detect if there’s a message collision and retransmit later.

We’ve added a few nice extras to this Feather to make it useful in many common CAN scenarios:

• 5V charge-pump voltage generator, so even though you are running 3.3V on a Feather board, it will generate a nice clean 5V as required by the internal transceiver.
• 3.5mm soldered terminal block quick access to the High and Low data lines as well as a ground pin, without any soldering.
• 120-ohm termination resistor on board, you can remove the termination easily by cutting the jumper marked TERM on the top of the board.
• CAN control CS, Reset, Int, standby pins connected internally so you can use any FeatherWing without pin conflicts.

At the Feather’s heart is an RP2040 chip, clocked at 133 MHz and at 3.3V logic, the same one used in the Raspberry Pi Pico. This chip has a whopping 8 MB of onboard QSPI FLASH and 264K of RAM!  There’s even room left over for a STEMMA QT connector for plug-and-play of I2C devices.

Feather of the Day: Adafruit Feather RP2040 with DVI Output Port #RP2040 #Adafruit #Feather

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather RP2040 with DVI Output Port – Works with HDMI!

Wouldn’t it be cool if you could display images and graphics from a microcontroller directly to an HDMI monitor or television? We think so! So we designed this RP2040 Feather that has a digital video output (a.k.a DVI) that will work with any HDMI monitor or display. Note it doesn’t do audio, just graphics!

It’s kinda like we took our RP2040 Feather and DVI Breakout board and glued them together. You get all the pins for use on the Feather, the Lipoly battery support, USB C power / data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, a DVI output that can be used CircuitPython or with the PicoDVI library in Arduino or Pico SDK

Note that the DVI video generation uses one full core, both PIOs, and 150K (320×240) or 190K (400×240) of SRAM. It’s kinda maxed out so be aware of the remaining resource limitations.

We also connected the HDMI-connectors I2C pins to the SDA/SCL of the Feather (through a safe level shifter) so you can read the EDID EEPROM of displays, and have broken out the CEC and Utility pads. The Hot Plug Detect pin is also available on the very end of the 16-pin header. Read this pin to know when a display has been connected!

Because it’s part of our Feather ecosystem, you can take advantage of the 50+ Wings that we’ve designed to add all sorts of cool accessories. Plus that built in battery charging and monitoring you know and love is here.

NEW GUIDE: Pico W YBox3 #Arduino Compatibles #AdafruitLearningSystem @Adafruit

A little over a decade ago, the YBox2 Kit was all the rage. It used a Parallax Propeller chip with Ethernet to connect to the Internet and display custom widgets via a composite video output. Years later, it felt like it was time to revisit this project concept with new hardware. The next generation YBox, the YBox3, uses a Raspberry Pi Pico W to run Arduino code that connects to WiFi and displays custom widgets via DVI output with a DVI PiCowbell.

Media Player With Raspberry Pi – Retrofited Vintage Clock Radio @Raspberry_Pi #PiDay #RaspberryPi

One of the disadvantages of having a smart phone is that we lose our need for technologies of old. Wasn’t it nice to wake up to a clock radio playing a random song, rather than a beep from an everything device that can lead us from alarm to doomscrolling with the flick of a thumb? On the other hand, these dead media devices can be repurposed in very cool ways. darkfly over at instructables has great project that turns a vintage clock radio into a media player. Here’s more:

I wanted to make a multimedia player with an above average sound system and a touch screen. I really had no idea of what I wanted the system to look like. After thinking of several design concepts, the answer came to me one day while walking through a thrift store. I realized that I didn’t need to create a unit to install the components in. I would simply repurpose an old object to serve as the case/frame for my multimedia center.

With this new idea in mind, I started looking at every single item as a possibility. I had many ideas about what to use; everything from wooden crates, old nightstands or even an old vinyl record. I know some ideas sounded crazier than others, but it seemed to be a fun direction to take this project in. Then I noticed something that I thought would work quite well, a vintage Philco clock radio. When I first noticed the clock radio, I fell in love with its old charm. It seemed like the perfect case/frame for my creation.

See project!

Tutorial: Add 12v Programmable Cafe Market Lights to your Outdoor Space

Add colorful, arduino controlled lights to your outdoor space. Install outdoor cafe market lights with edison-style bulbs and addressable LEDs inside, and control them with code to create an amazing ambiance in your yard.

These lights require 12v, and most microcontrollers need 5v power. This guide will show you how to use a QT Py SAMD21 and a DC Power BFF add-on to power both the lights and the controller from one power source.

From the guide:

Cafe-style light strands with edison bulbs are a beautiful way to decorate your patio. They are a fantastic and classy way to light up any outdoor space. Wineries, bistros, and night markets use them to create a cozy, intimately lit space that’s warm and inviting to diners, and they look fabulous in backyards of just about any size.

These lights are a programmable, addressable version of the cafe market lights you can find at the hardware store. Add Arduino or CircuitPython code and you can turn your lights on in party mode, sending warm rainbow animations across your yard.

These lights require 12v power, and also need to hold up in an outdoor environment. This guide will focus on how to power a 5v microcontroller and 12v lights from the same setup, and also show how to use a waterproof enclosure to keep your lights safe from rain and weather.

For the recent birthday party, Kauzerei had the great idea to build a DIY drum machine as a present, to allow them to play the bass without having to gather a jam session group. He recruited Thomas Buck for electronics design brainstorming and to write the firmware.

The drum body consists of a tambourine with a 3D printed frame attached, with three hand-wound solenoids mounted on there. The positioning and different hammers create some (slightly) differing sounds.

The electronics are made with a Raspberry Pi Pico (or Pico W in this case, although WiFi or BT are not used yet). This keeps the future option of a USB Midi input open.

The user interface consists of four buttons, each with an LED above, and a clickable rotary encoder, as well as a power switch and an 128×64 SSD1306 OLED display. To drive the solenoids, three step-up converters create ~16V from the single Li-Ion 18650 cell. Their output is then switched to the solenoids using MOSFETs. A small TP4056 module handles recharging the battery.

Repairing a mug with Japanese kintsugi #ArtTuesday

Fredrik Flornes Ellertsen provides a tutorial for Japanese kintsugi, repairing ceramics with a distinctive gold finish. Fredrik’s special mug was the target:

Kintsugi is the traditional Japanese art of repairing broken pottery. In Kintsugi, one uses natural lacquer mixed with various ingredients such as wood powder, polishing compound, and even bread dough to repair cracked pottery. The mended joints are then highlighted by dusting the final layer of lacquer with gold or silver.

See how this method is used to save precious objects and make new unique art pieces in the tutorial here.
