3D Print Your Way to a Modular MIDI Playset

Have you ever wanted to experiment with MIDI, but didn’t know where to start? Or perhaps you didn’t think you could afford to properly outfit your digital beat laboratory, especially given the average hacker’s penchant for blinkenlights? Well worry no more, as [Johan von Konow] has unveiled a collection of DIY MIDI devices that anyone with a 3D printer can build on the cheap.

The LEET modular synthesizer is made up of a keyboard, drum pad, chord keyboard, arpeggiator and a step sequencer that plug into your computer and interface with industry standard digital audio workstation (DAW) programs. The down side is that they don’t do anything on their own, but this simplification allowed [Johan] to really streamline the design and bring the cost of the build down to the bare minimum.

Jeff Geerling Squeezes 4.15Gb/s From a RaspberryPi Compute Module 4 Using a PCIe Network Card

Jeff Geerling has succeeded in pulling over 4Gb/s of data from a Raspberry Pi Compute Module 4, by hooking up a four-port Ethernet card to its PCI Express bus — and the same may well be possible on a modified Raspberry Pi 4, too.

Launched last month, the Raspberry Pi Compute Module 4 takes the core technology found in the popular Raspberry Pi 4 Model B and brings it to a system-on-module (SoM) form factor. The biggest shift from the original design, though, comes with making the USB 3.0 ports optional and replacing them with a fully-functional PCI Express Gen. 2 lane — suitable for all manner of add-on boards, providing you can find suitable drivers for the Arm architecture.

Nintendo Flex Is The New Gameboy You’ve Been Waiting For

The Gameboy is without doubt the most recognised console of all time, so it’s about time a new gameboy concept was produced, just so we can tease our nostalgia nerves and internally cry on the inside knowing this thing will never truly exist. But it’s always nice to see what artists and graphic designers come up with.

Update: The new Gameboy you may be looking for is the Analogue Pocket release that was revealed not too long ago, and has a release date for May 2021.

The designer known as YJ Noon wanted to redesign the old classic into a metal Gameboy with a slight curve, using fresh metals, and modern day technology to transform it into something totally unique. There isn’t much detail or specifications on the new Gameboy itself, but we’ll take you through what could be its features.

ESP32-C3 WiFi & BLE RISC-V processor is pin-to-pin compatible with ESP8266

When we reported about ESP32-S2-MINI modules last September, we also noted Espressif teased us with ESP32-S3 and ESP32-C3 with close to no details. ESP32-S3 is expected to be a multi-core WiFI & Bluetooth processor with AI instructions/accelerator, but there were no details about ESP32-C3 at all, and we only found out it would be a RISC-V processor several weeks ago.

But Twitter user Johnny Wu posted a screenshot in Chinese and its translation claiming ESP32-C3 was finally released by Espressif Systems. [Update: The datasheet has been released. See comments.]

ESP32-C3 WiSoC is pin to pin compatible with ESP8266, works with ESP32 development framework (e.g. ESP-IDF), supports Wi-Fi & Bluetooth LE 5.0 connectivity, and integrates 400KB SRAM & 384KB ROM. It features a single32-bit RISC-V (RV32IMC) core @ 160 MHz, and consume as little as 5uA in deep sleep mode. Pricing will also be similar to ESP8266.

Control a wheelchair using an EEG headset and Arduino

In an effort to help provide paralyzed patients with an easier way to operate their wheelchairs, these makers have developed a system that uses an OpenBCI brainwave cap to collect electroencephalogram (EEG) and electromyography (EMG) signals, literally from a user’s head. Data is then sent to a PC running OpenBCI software and passed along to an Arduino Uno via Bluetooth for control.

MeLE PCGO 2 It’s A Fanless Mini PC Stick With 8GB Of Ram!

In this video, we test out the all new MeLE PCGO2, A Fanless Mini PC Stick with 8GB of Ram and powered by the Intel Celeron J4125 CPU! Capable of 4K resolutions and it runs Windows 10, Linux, and even Android On paper this looks like a nice little totally silent Mini Stick PC but how does it really perform? IS it any better than the Chuwi LarkBox or the Lark Box Pro? test out some 4k video playback from YouTube and PLEX and finally wrap it up with some PC gaming with games like Sky rim, Overwatch, and even CS-GO.
SO is it worth buying? Let’s find out

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.
