Make your own power bank out of any (1000 mAh or over) lithium battery! Are you a fan of bi-directional USB-C? Hey, so are we! This awesome little board goes both ways - the USB-C connector is both an input to charge a lithium battery at 1.0-1.2A and an output that provides a boosted 5V from the battery at 1.2A!

Engelbart's demo also featured an input device known as the keyset, but unlike his other innovations, the keyset failed to catch on. The 5-finger keyset lets you type without moving your hand, entering characters by pressing multiple keys simultaneously as a chord. Christina Englebart, his daughter, loaned one of Engelbart's keysets to me. I constructed an interface to connect the keyset to USB, so that it can be used with a modern computer. The video below shows me typing with the keyset, using the mouse buttons to select upper case and special characters.

Look, I’m just going to come out and say it… this Giant USB Button is probably too big! It’s 228.6mm x 228.6mm x 120mm (which is 9″x9″ x 4.725″). The thing is, when someone asks me to build something for them, and it seems interesting, I can’t really say no. And I did say “no” this time, but mainly due to the tight deadline. I said I would need about twice as much time as requested and luckily the client came back with “We can do that!” So I got to work…

Can some chargers damage my device? Yes. Not all, but definitely some. The damage is caused by the RG35XX Plus mistakenly detecting that some USB C chargers are an external device (like a USB gamepad) that needs power, and trying to apply 5V to the charger itself. This can result in either or both the RG35XX Plus and the charger to heat up - sometimes just a bit, sometimes enough to damage components or the nearby battery. Read below for an explanation about how this happens. If I want to be safe, what chargers are definitely going to be okay to use? Anything that uses a cable with USB A on one end, and USB C on the other. The voltage and current rating of the charger itself makes no difference. This doesn't mean that no other setups will work (for instance, most tethered USB C chargers, or non e-marked C<->C cables will), but using an A<->C cable is the only straightforward way for most people to be sure. Is there a mod to enable charging on all USB C chargers? Yes, but you lose the ability to power other devices from the USB C port on the RG35XX Plus, and it involves soldering tiny SMD components. Is this relevant to other RG35XX family devices? Probably, but I don't know - I've only had a look at the RG35XX Plus. Specifically, mine is marked as a "RG35XX Plus V6.0, 2024-01-09" inside on the PCB.

USB Insight Hub plugs into your computer through a USB Type-C connector and exposes three USB 3.0 downstream ports, each with a 1.3-inch screen that displays relevant information about the attached device. That information includes operating system enumeration name (COMx, TTYx, or drive letter), voltage, and current. USB Insight Hub also allows you to control the individual activation and deactivation of the D+/D- USB 2 data lines to force enumeration and control the power of each downstream device. A small application running on the host computer extracts USB information from the operating system and sends it to the Hub over USB.

Ventoy is an open source tool to create bootable USB drive for ISO/WIM/IMG/VHD(x)/EFI files. With ventoy, you don't need to format the disk over and over, you just need to copy the ISO/WIM/IMG/VHD(x)/EFI files to the USB drive and boot them directly.

Direct drop in replacement controller. Perfect if you have a dead controller, or you want to tinker with extra options without modifying the stock controller, or you just want a programmable internal USB connection.

This blog post explains how to fix the no permissions error the Android Debugger displays when running the adb devices command Linux. The solutions presented here have been tested and found working on Ubuntu Lucid, but they should also work on other Ubuntu and Linux versions as well.

I've been noticing more and more consumer gadgets(Phones/MP3 players) are making use of a Mini USB plugs connect to their charger. I figured why not try adding it to my DS Lite. As it turns out it's a fairly straight foward hack as the pinout and spacing are almost identical between the two connectors.

HoRNDIS (pronounce: “horrendous”) is a driver for Mac OS X that allows you to use your Android phone's native USB tethering mode to get Internet access. It is known to work with Mac OS X versions 10.6.8 (Snow Leopard) through 10.9 (Mavericks – see notes below), and has been tested on a wide variety of phones. Although you should be careful with all drivers that you install on your computer, HoRNDIS has been tested at least well enough for the author (and many others) to run full time on their own personal computers.

Stay away from super-cheap AC adapters built by mystery manufacturers. Spend the extra few dollars to get a brand-name AC adapter. It will be safer, produce less interference, and your device's touchscreen will perform better.

All modern TVs support HDMI-CEC a technology that allows devices to talk with each other over the HDMI cable, using this feature this adapter will send and receive remote key presses to XBMC or MythTV or Windows Media Centre or any other app that supports libCEC on your PC

Communicating with a host computer can allow a simple Arduino-based system to gain access to a wide variety of devices and information. Most people link an Arduino to a host using serial communications across a USB connection with custom code running on the host to send information to the Arduino or receive it in return, but giving your Arduino the ability to pretend to be a keyboard or mouse opens up a whole world of possibilities because it means your Arduino can interact with software that was never intended for external control. That could be desktop software such as a game or a web browser: your Arduino could "type" into a web form and submit it on your behalf, or act as a custom controller for a game!

Project log for developing USB expansion shield for Arduino and associated code.

We've seen monitors with touch input and displays powered only by USB, but combining both those features into a single unit would make for something truly unique. We've gotta hand it to Mimo Monitors for pulling it off -- the Magic Touch and Magic Touch Deluxe deliver 10.1 inches of capacitive interactivity using only a single USB 2.0 cable. The panel itself offers a resolution of 1024 x 600 for keeping video chats out of your way, displaying email or monitoring social networks. The Deluxe version also adds a two-port USB hub but, if you plan to charge your devices through it, you'll have to hook up the optional AC adapter. Sadly, while they can act as a secondary monitor regardless of OS, you'll need a Windows 7 machine to take advantage of the touch capabilities -- and even then it's single touch only (though, the panel itself is technically capable of four-point multitouch). Both models are available to pre-order now for $300 (Magic Touch) or $330 (Magic Touch Deluxe) with delivery expected before Christmas. Check out the complete PR after the break.

I wanted to add vi cursor keys and mouse keys to HHKB. Original HHKB controller is not programmable and firmware source code is not open. So, customizing HHKB needs to replace original controller with programmable one. I used Teensy++ as alternative controller. Though a Teensy has enough ports to drive HHKB, Teensy++ has clean pinout and it makes programing and wiring easier. I should look into this to see if I can fix the PS/2 HHKB that I apparently fried with a USB adapter.

Inspired by the allegedly Windows Android x86 demo with a 23 inch multi-touch screen by Martin Drashkov (see second video below), I decided to give my own version a spin.

This is revision 2.0 of USB Host Shield. Thanks to new interface layout it is now compatible with more Arduinos – not only UNO and Duemilanove, but also big Mega and Mega 2560 work with Standard variant of this shield out of the box. No more SPI re-wiring and code modifications – just solder included stackable connectors (2×3 ICSP connector’s female side should be facing down), plug and play!

Our USB IR Transmitter/Receiver is a standard USB device that can transmit and receive the infrared codes supported by LIRC (Linux only) and WinLIRC (Windows only and beta). Combined with (Win)LIRC, this device can communicate with most home electronics, such as TVs, stereos, DVD players, receivers, and their associated remote controls. When used with MythTV, you can turn your computer into a TiVo-like media center.
