I finally finished the next version of my TinyLoadr AVR programming Shield – and it’s not a shield. It’s a standalone USB programmer, so you no longer have to have an extra Arduino laying around. The best part? It’s the same price as the shield was!

Banguino brings the most popular hobby and DIY development platform in the world into a single chip DTX module and offers full backwards compatibility with the most used worldwide Arduino board – the model ‘Uno’.
Bonus features include an on-board power supply to generate +5V and +3.3V to the user’s external circuit, a microSD connector and additional 10 configurable digital I/O ports. There are also two software controllable LEDs on board as well as a USB-to-UART bridge. Banguino provides a highly integrated solution for building simple or complex circuits and benefiting from the large variety of already existing Arduino-compatible code.

Espruino Pico has everything you need pre-installed. It can be used from virtually any device with a USB port so you can get started in seconds.
Today, we’ll be discussing Rigol’s MSO2302A Mixed Signal Oscilloscope from the MSO2000A series. Starting at $1,239, this oscilloscope features 300 MHz bandwidth, with 2 giga-samples per second, a memory depth of 14 megapoints (Mpts), with an option up to 56 megapoints. The large 8 inch high resolution screen typical to Rigol scopes allows for easy review of your data. 2 channel input and has an ethernet connection for networking and USB ports to interface with computers, save waveforms to USB storage devices, or print directly to printers.

Ever wanted to visualize your brain activity in real-time? Move an object on a screen with your mind? EEG devices are fantastic fun and allow you to do such things!
This tutorial will show you how to make an illumino: an easy-to-use recreational EEG device hidden inside a comfortable beanie, that turns your brain activity into an array of colorful light. Colors and brightness are manually selectable and adjustable via a small discreet pushbutton switch. The custom Arduino software is accessible via a USB port, allowing you to easily change it as you wish. The hat also works fine without the lights, should you wish to use it only as an EEG device. I recommend using Processing to create beautiful real-time moving graphical visualizations of your brain activity (code included in tutorial).

USB connected TI TMS320F28027 based ZRLC Tweezers with
Most Digital multi-meters measure Resistance and Capacitance and LC-meters can measure Inductance and Capacitance. Presented here is a ZRLC meter which can measure Resistance, Capacitance, Inductance and Complex Impedance.
The hardware is built around a TMS320F28027 micro-controller an 8-port-analog-switch ADG714 from analog-devices and a Microchip rail-to-rail dual operational-amplifier MCP6022.

ajoyraman posted a tutorial on how to make a DIY USB-matchbox oscilloscope, an instructable here:
In order to economize on the cost of an enclosure while still providing an aesthetic unit the Aj_Scope2 is enclosed in a large size cardboard matchbox enclosure.
The USB connection to the PC is on one end while the Audio-Jack for the signals to be monitored is on the other.
A ‘Busy’ LED is provided on one corner at the top and a ‘Reset’ switch is provided diagonally opposite.
The ‘Reset’ switch provides a restart of the micro-controller is the worst-case of hang-up. This typically occurs when the operator selects a trigger threshold which is out of limits with respect to the waveform being observed. If the Aj_Scope2 is operated correctly this switch is seldom used.

If Arduino is your development platform of choice the tiny self-contained MicroLink board offers some interesting features. At just 50 x 32 mm it contains an ATmega328, an SIM800H quad band GSM module and on-board USB and battery charging capabilities. It has all the peripherals necessary to allow wireless remote control and monitoring and can use any standard 3.7 V LiPo battery for power which is charged when the USB port is connected. The charge state can be checked at any time from a remote location.

RFID keyboard emulators are able to significantly simplify tracking of goods.
“Replacement” of a keyboard in a form of an RFID module connected to a USB port works very simply – UID of every tag, which will appear in its range will send to a computer – the same way as if we typed it in by a keyboard. SL040A also enables to choose, whether we want the reader to send only data, or also a „CR“ character after every UID (as if an Enter key was hit). It means, that if we already have a software to type in open (for example Excel), the reader itself will fill the cell with data and move the cursor to another cell. SL040A is even able to read data (not only UID) from Mifare tags.
SL040A is also interesting by one feature – on a request from our company SOS electronic, the producer started to produce also the black version SL040A black. Thanks to the above-standard close relationship with the producers, we´re able to supply you even various special customized versions.
Detailed information will provide you the SL040A user manual.
