Friday Hack Chat: Perfect Purple PCBs

We’re doing a Hack Chat this Friday at 12:00 pm US PDT!oshparkhackchat.png

Friday Hack Chat: Perfect Purple PCBs

Every Friday, we gather ’round the hot air gun over on Hackaday.io, invite some cool people over, and get them to talk about what they do. This is the Hack Chat. It’s become a tradition, and already we’ve had a ton of awesome people walk through our doors.

This week, we’re inviting [Drew Fustini] and [Dan Sheadel] to talk about what OSH Park does, how they became the first place that comes to mind when you need a PCB. They’ll explain why the boards are purple, environmental regulations for PCB manufacturing in the US, shared projects and tips and tricks for creating the perfect board.

Hackaday Prize Entry: Internet of Fidget Spinners

Last week, everyone on Hackaday.io was busy getting their four project logs and illustrations ready for the last call in this round of the Hackaday Prize. These projects are the best of what the Internet of Things has to offer because this is the Internet of Useful things [..]

This is a PoV fidget spinner, which means the leading edges of this tricorn spinner are bedazzled with APA102 LEDs. Persistence-of-vision toys are as old as Hackaday, and the entire idea of a fidget spinner is to spin, so this at least makes sense.

Hackaday Prize Entry: Sub Gigahertz RF

For his Hackaday Prize entry, [Adam] is working on an open source, extensible 915 and 433 MHz radio designed for robotics, drones, weather balloons, and all the other fun projects that sub-Gigaherts radio enables.

The design of this radio module is based around the ADF7023 RF transceiver, a very capable and very cheap chip that transmits in the usual ISM bands. The rest of the circuit is an STM32 ARM Cortex M0+, with USB, UART, and SPI connectivity, with support for a battery for those mobile projects.

LiFePO4wered/Pi+

Patrick Van Oosterwijck created this board to power the Raspberry Pi with a LiFePO4  battery:

LiFePO4wered/Pi+

Many IoT and other projects are based on the Raspberry Pi, but usually little thought is given to the power supply. Most project use generic cell phone adapters or USB power banks, which is fine for one-off projects where the duct taped parts and cabling don’t matter and it’s expected that SD cards will die because power was removed with the Pi running.

But when you need reliable non-stop operation for your prototypes, or you’re ready to turn your project into a good looking product, or you want to use different power sources such as solar, it’s time to look for a serious power manager for your Pi.

Built on the solid foundation of the #LiFePO4wered/Pi, this project provides Pi bootup and shutdown management based on button or touch, input voltage, battery voltage and time, all while making sure the Pi always performs a clean shutdown before power is removed.

CPLDuino

Jeremy g. designed a mashup between an Arduino Uno and a Xilinx 9536XL CPLD:

CPLDuino

The XCACDV3, CPLDuino is a single board solution to meld Atmels ATmega 328 RISC microcontroller with a Xilinx XC9536XL1 CPLD. Allowing for rapid prototyping of digital circuits without the need for a breadboard. The CPLDuino is capable of passing information from the on board ATMega328 to the CPLD and vice versa, allowing for real-time data monitoring. Thanks to the on-board CP2102 USB to Serial UART, data can be viewed and manipulated via the virtual com port.
