Modems have been around for longer than the web, and before we had Facebook we had the BBS scene. Somewhat surprisingly, people are still hosting BBSes, but have fun finding a landline these days. [Blake Patterson] is one of the leading aficionados of retocomputers, and recently he took it upon himself to review an interesting new…
Exciting project by Alex Wulff on Hackster.io:
This whole circuit is the same size as a regular poker chip, but with an added surprise: lights!
Spice up your poker games with these cool blinking chips. They can be programmed on the fly to have a certain number of the LEDs illuminated to indicate value, or you can have the lights blink in a cool pattern. They make great playing chips for championships or great prizes to hand out to the winners.

Brian Rutkowski’s impressive LED spinner project was a crowd pleaser!

Simula made several new friends:
We were excited to get a look at the purple PCB inside:
We were excited to meet Jose Ignacio Romero who had designed the Low Power Continuity Tester for the One Square Inch contest on Hackaday.io last year. He brought many projects to share including this color memory LCD board:

What is the Tinusaur project about? Here we will explain it to you step-by-step.
Brian Benchoff writes on Hackaday:
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.

We are pleased to announce that OSH Park, the purveyors of perfect purple PCBs, have become sponsors of the FOSSi Foundation’s activities. We are very grateful for their support and would like to recognize this by listing them on our Sponsors page at the Bronze tier.
We are actively looking for sponsors for the Foundation, if you’re interested in learning more about our activities and why we are looking for sponsorship, then please visit our sponsorship page and for more, see our detailed sponsorship proposal document.
More information on the FOSSi Foundation:
Inspired by the success of open source software, the Foundation will help bring about IP and tools of comparable quality to proprietary offerings, and which are developed according to an open source model by a highly collaborative and inclusive community. The FOSSi Foundation will address the issues the field currently faces; fragmentation, legal uncertainty, design quality, and high barriers to entry.
FOSSi has launched LibreCores:
gateway to free and open source digital designs and other components that you can use and re-use in your digital designs.
FOSSi also organizes the ORConf:
[Ross Fish], [Darcy Neal], [Ben Davis], and [Paul Stoffregen] created “the Monolith”, an interactive synth sculpture designed to showcase capabilities of the Teensy 3.6 microcontroller. The Monolith consists of a clear acrylic box covered in LED-lit arcade buttons. The forty buttons in front serve as an 8-step sequencer with five different voices, while touch sensors on the left…
General Instrument’s AY-3-8910 is a chip associated with video game music and is became popular with arcade games and pinball machines. The chip tunes produced by this IC are iconic and are reminiscent of a great era for electronics. [Deater] has done an amazing job at creating a harmony between the old and new with his Raspberry…
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.
Tindie is a great place to find uncommon electronic components or weird/interesting boards. [Xose Pérez] periodically “stroll the isles” of Tindie to keep up on cool new components, and when he saw Panasonic’s Grid_EYE AMG88 infrared sensor, [Xose] knew that he had to build something with it. The awesome find is an 8×8 IR array…
