Web the RIPper

Most people remember bulletin board systems as having chunky text-based graphics. One developer tried fixing that, but RIPscrip ran head-first into the web.

Today in Tedium: Bulletin boards, love them or hate them, quickly became relics of their time for a few reasons. One of the most visible, for obvious reasons, was the graphics. Say what you will about the gracefulness of a text interface with colorful ANSI graphics, but for many consumers, it could simply not compete with the literal photos and graphical user interfaces of the World Wide Web. Bulletin board operators, some of whom had built out sizable businesses around their onetime hobbies, were aware of this problem, though, and were trying to help build a second life for their systems that modernized them for the next generation. And that meant getting graphical. Problem was, the digital climate was moving too fast even for nice graphics. Today’s Tedium talks about efforts to give BBSes graphics and why RIPscrip, as the most popular effort was called, might have been secretly ahead of its time.

WhatsApp Halloween-Themed RFID Talking Doorbell w/ RGB Eyes

Despite the fact that making a hilarious yet not deceitful joke with a jack-o’-lantern on Halloween night is not unobtrusive, I decided to create an exceptional event for my guests on Halloween when they ring the doorbell by designing a jack-o’-lantern doorbell with intriguing features. And, not surprisingly, I only let some of my closest friends know about my new doorbell features by giving them registered RFID tags (entrance permits) to make my other guests frightened even a little bit 🙂 In detail, this doorbell talks to the guests and informs the user via WhatsApp when the guests ring the doorbell or show RFID tags or cards.

First of all, to make the doorbell talking with the guests after an interaction, I generated voices from texts for each occasion I wanted the doorbell to talk. You can get more information about how to create voice files over text files in the following sections.

The GPRino is a $300 ground penetrating radar

Ground penetrating radar systems, which can be used to sense the density of objects under the Earth, are normally seen as a fairly exotic piece of equipment. Naturally, such devices cost thousands of dollars. Mirel Paun’s “GPRino” prototype, though, aims to accomplish this viewing task for the comparatively paltry sum of $300.

The GPRino uses antipodal Vivaldi antennas to see into the ground, under control of an Arduino Mega. Onboard visualization is handled by an LCD shield, and collected data can also be transmitted to a PC for further analysis.

This Oscilloscope Tester Keyring Puts ‘Scope Troubleshooting Powers in Your Pocket

The Engineering Octopus has launched a keyring with a difference: As well as helping you keep track of your keys, it doubles as a means to quickly test an oscilloscope — hence its name, the Oscilloscope Tester Keyring (OTK).

“All electronic engineers love to show off the fact that they are electronic engineers, and what better way to do that than with a keyring! Not only will the bare electronics be noticed by many, it’s also a fully functional oscilloscope tester,” The Engineering Octopus founder Max writes. “The OTK generates a pure, analog, sine wave (via a Colpitts oscillator) at approximately 10MHz (+/-2MHz). It has a DC offset, which allows you to test almost all functions of a oscilloscope, and carry it with you everywhere you go!”

α-WaLTR Turns It Wheels Into Triple-Bladed “Legs” to Navigate Uneven Terrain — and Even Stairs

Built as part of a military program but with wide-ranging use-cases, α-WaLTR goes where other wheeled robots fear to roll.

Researchers at Texas A&M have designed a compact four-wheeled robot for whom stairs and other uneven terrain pose no problems — thanks to wheels which can transform themselves into “legs” on demand.

Dubbed α-WaLTR, for the Adaptable Wheel-and-Leg Transformable Robot, the robot has been built as part of DARPA’s Offensive Swarm-Enabled Tactics (OFFSET) programme under the leadership of grant awardee Associate Professor Kiju Lee. “Through this new project,” Lee explains, “I will develop unmanned ground vehicles with agile and versatile locomotive capabilities for urban military operations.

Using ESP8266 WiFi Module with Arduino Micro

Although the ESP8266 01 WiFi Module has a wide support and a good community crowd, the Arduino Uno board takes advantage of it’s ease of use and beginner-friendly layout over Arduino Micro for being one of the most used boards for cheap IoT solutions. As a result, there aren’t many tutorials documenting how to use the module with this board. So here’s a short & simple tutorial for people getting started with IoT and want to use the Micro+ESP01 combination.
