Solder Scroll – Ergonomic Adjustable Solder Dispenser Tool #3DPrinting #3DThursday

victordesigns shares:

A 3D-printed ergonomic solder feeder you wind manually like a pen. Roll solder onto the integrated spool, feed it through the main body, clip in the spool, and you have one-handed solder dispensing. Includes remixes from the community. By Victor

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

smolutils: like coreutils but smaller

Daniel Palmer has developed smolutils, “because for space constrained targets, even uclibc + busybox isn’t very usable due to space.”

For nommu, every process loads its own copy of everything because there is no virtual addressing to allow sharing of common physical pages. So every process has its own copy of uclibc and busybox and even if that is ~100K you will end up using a lot of memory just getting booted and might not be able to allocate a big enough single block to run anything. Maybe FDPIC solves this but that doesn’t seem to be supported on m68k.

To date, only a subset of Linux/Busybox shell commands are implemented. Work is progressing.

NEW GUIDE: Adafruit ADS7128 8-Channel ADC and GPIO Expander #AdafruitLearningSystem @Adafruit

The Adafruit ADS7128 8-Channel ADC and GPIO Expander is a bit of a Platypus of the I2C expander world: hard to categorize as just an ADC or a GPIO expander since it combines the capabilities of both! Featuring the aforementioned ADS7128, it can run on 3.3 or 5V logic and power, and all 8 I/O pins can individually configured to perform either 12-bit SAR analog input, push-pull or open drain digital output, or digital input.

The Adafruit ADS7128 8-Channel ADC and GPIO Expander guide has everything you need to get started with this ADC. There’s pages for overview, pinouts, CircuitPython, Arduino and resources for download.

NEW LEARN GUIDE: USB Morse Code Key with CircuitPython #CircuitPython #AdafruitLearningSystem @Adafruit

 

The TinyUSB library underpins many CircuitPython’s USB capabilities. It’s what lets CircuitPython act as a storage drive, CDC, HID, MIDI and more. Starting with version 10.3.0-alpha.3 CircuitPython has added support for USB audio types. This guide demonstrates usage of the USB microphone capability to generate tones and output them to a computer or other digital audio equipment. You can connect a basic key to tap in Morse code live, and use the generator function to automatically convert strings into beeps and boops.
