Pi Extension board "PiEBridge"

"PiEBridge" is an extension board for microcomputers similar to the Raspberry Pi (Pi), which is designed to be a helper for the DIY-maker in all his activities - Pi, together with PiEBridge, can perform a variety of functions:

universal programmer

software and hardware debugger for target systems

PCB fusion furnace controller

smart-home controller

as well as do many other useful things

You might say Pi already knows how to do these useful things, so why does it need more extension boards? Here is the answer to that question:

PiEBridge transforms the Pi's 40-pin I/O subsystem into more practical 6/10-pin lines for many applications and provides signal integrity for these lines

adds the simplest controls and indications (button, pedal, and LEDs)

has a programmable 2.5...5V power supply for external devices

"Naked" Pi is usable in two extreme configurations - either just a box controlled externally via SSH or a desktop computer with a monitor, keyboard, and often even a mouse. In addition to these typical use cases, PiEBridge allows you to use the Pi as a standalone software automaton to perform random repeating tasks with minor interactive operator participation.

PiEBridge is plugged into the Pi extension connector (compatible with family models with a 40-pin connector) and installed vertically. For this purpose, the Pi case (if available) must have a corresponding cutout on top.

When used as a programmer, PiEBridge can work with most known 6-pin and 10-pin connectors, and GND and Vcc can be randomly connected to their pins to ensure compatibility.

The programmable power supply for external devices is programmable on/off and programmable in the range of 2.5 - 5V with an accuracy of about 2%.

Deb-packages for PiEBridge have been created and compiled into a repository:

general-purpose, providing configs and libraries for working with controls and indications, as well as with the power supply

special purpose, e.g., applications for MCU and FPGA programming and debugging

auxiliary purpose, for example, for repeating operations automation (like mass-production function for firmware flashing). In this case, the user can use settings that provide autonomous launching of the necessary software when the Pi is turned on, and then (after finishing its work) its simple parking and shutdown by pressing and holding the button for a long time.

metapackages, which cause installation of necessary software and configs for the selected role and allow to simplify preparation for work

Improvisation using no-input mixer, stylophone, loopers, and my drum synth (pure data on raspberry pi) + midi controller. I have updated my drum synth patch to add a (non-quantised) tap-a-pattern function for the kick drum hence the wonk.

The visualisation is a Lissajous figure, produced by software called PrettyScope.

Do you have any tips to be more punk in 2025 specifically for minors?

Hey, great question! Let's take a look at our list and see what still applies and what we can flip around for you.

Cut fast fashion - Still applies! Try clothing swaps with friends.

Cut subscriptions Analyze your media consumption - Do you tend to play phone games that are psychologically manipulative? Are algorithms taking you to content that makes you upset? Track your screen time, think about what's being sold to you, and resist only consuming the media that is fed to you.

Green your community self - Forget touching grass, find ways to touch dirt. Spend time outside in nature. Go for hikes, look at trees, track how plants and animals change over the seasons. You're part of the natural world, so go connect with it!

Be kind - Still applies! Try handing out more compliments.

Intervene - Still applies, and especially applies to bullies, including teachers. This can be as simple as saying, "That was a really messed up thing to say. I think you owe X an apology."

Get closer to your food - Still applies! Try packing your lunch.

Use opensource software Reject Web 2.0 - Before you try to learn Linux, people your age need to start by learning some basic computer and coding skills. My generation was given computer classes and had social media that encouraged custom coding. Yours has been deprived of this education and given prepackaged web content. Reject AI. Right click + inspect element + fuck around. Learn Raspberry Pi. Become the cyberpunk hacker you want to see in the world.

Make less trash - Still applies! If mom won't let you start a compost in the backyard, propose starting one at school!

Get involved in local school politics - Know what's going on with your school board, with school administration. Start an underground, uncensored school newspaper with the real dirt.

DIY > fashion - High school is where a lot of adults learned their bad habits about keeping up with appearance/fashion demands. Refuse to buy in now and make homemade the new cool.

Ditch Google - Still applies! And also check your app settings to see if you have apps with unnecessary permissions.

Forage - Still applies!

Volunteer - Still applies! There might be fewer opportunities for minors, but you'll never know until you ask. Don't be afraid to be the only young person at the volunteer session.

Help your neighbors classmates - Offer to study with students who are struggling. Become someone people can trust to tell if their home situation is difficult. If you have friends who don't get enough to eat at home, bring them home for dinner. Check on people.

Fix stuff - Still applies! This can be a fun activity with friends, too. Let's all hang out and see if we can fix this busted stereo!

Mix up your transit - Still applies! Is taking the bus considered lame at your school? Do it anyway.

Engage in the arts - Still applies! Pay attention to art events that your classmates are putting on. Go to the school play - or join! Stop in the art classrooms to see what people are working on.

Go to the library - Still applies, public and school libraries! Talk to the librarians - they know things. Find out if there are after school programs you can take advantage of.

Listen local - Even more local! Stop by the band room after school to listen to practice. Does someone in your school have a band? Listen to them, cheer them on! Start a band! The great thing about punk music is that you can be really, really awful and still sound punk as hell.

Buy local Barter local - Lots of young folks don't have much control over or access to money, but that doesn't mean you and your classmates can't engage in barter. Figure out what you have to offer that other people might want, and trade for stuff you want. I used to cut hair and pierce ears in exchange for weed and rides to the mall. Maybe you can sew a friend's jacket in exchange for them bringing you a homemade lunch.

Become unmarketable - Still applies! PLEASE do this.

Use cash Steal ethically - Before engaging in shoplifting, make sure you know who you're stealing from! Stealing from Walmart is morally correct. Stealing from a family-owned grocery, a local coop, or a local artist? That fucking sucks, dude. Don't do it.

Give what you can - And only what you can. We ask a godawful lot from teens. You're in school all day, you're doing extracurriculars and maybe working and doing homework. You probably don't have a lot of money. You probably don't have a lot of time. But maybe you can bring your elderly neighbor's trash cans up from the street. Find the small actions that you have space for.

Talk about wages - PLEASE! If you have a job, this applies to you even more. Why? Because the adults working at your minimum wage job probably can't afford to be rabble rousers, but what do you have to lose except your shitty part-time Panera job?? A teenager who doesn't actually need their job to live has the opportunity to be the voice of truth in any workplace.

Think about wealthflow Resist indoctrination - Education systems are being gutted. Algorithms are feeding us misinformation. Cocomelon probably gave you ADHD or some shit - Jesus. It's a mess. Do what you can to practice critical thinking, expand your literacy, read stuff that seems boring. Start a book club or philosophy club with your friends. Ask who's profiting from a given situation. Resist knee-jerk reactions. Becoming an educated, thoughtful person is one of the greatest acts of resistance a young person today can engage in.

TLV320DAC3100 first bops 🔊🎶💃🕺

OK, after many hours spent with Claude on writing a driver for the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/TLV320DAC3100IRHBR/2260591), we finally have it configured using our driver, and playing an MP3 stream on this ESP32. This I2S DAC has a particularly complex PLL and audio-routing system, so it's not one where you can just pipe in I2S data and have it magically play. One nice thing we got working on is the MCLK, which is generated from the BCLK, so it'll work great with anything from an Arduino-compatible to a single-board computer like Raspberry Pi. We're hoping to get the headphone detection working next so that we can turn off the amp when the headphone is plugged in. Also, it should be able to control the volume from the headset buttons. Also, we want to get the internal beep generator going so we can make tones separate from the audio stream for UI notifications.

Out of curiousity, how did you get into doing this sort of computer work? Especially more low level stuff. :]

How can other people get into it / what would you like to see people make in the future in this area?

- Aspiring Programmer

I was an extremely poor kid, in middle school I learned about piracy which led to me getting into FOSS software for media conversion so I could load a bunch of media onto my psp. A short time later I learned about cfw, custom firmware, for psps when I was trying to figure out how pirating games for the system worked, that led to my first hardware hacking, at the time you needed to make a "magic battery" in order to save money on hacking the system which luckily for me I was able to do with a busted battery. That was really my big start because it was so exciting to be a poor kid with access to tons of games and media all of a sudden. Since then I've been very interested in firmware work and embedded systems, though I definitely didnt know thats what it was at the time.

For getting into software/hardware hacking/programming in a similar way I'd seriously recommend getting a cheap SBC, something like a Raspberry Pi Zero or just a Raspberry Pi is a good place to start especially since there are tons of projects for those boards that you can hack on and tons of very useful programs like pi-hole which does DNS ad blocking.

As to what I'd like to see people do: more projects dealing with media on these kinds of systems, video djing, glitch art, etc, because usually you're limited to something like VLC for media.
