Low Voltage Metal Sensor directly compatible with Arduino type computers for Robotics, Hobbyists, & Engineers without using magnets.
The Low Power Non Magnetic Inductive Proximity Sensor is a Great way for Engineers, Makers, and DIYs to easily detect low permeability (non iron) metals such as aluminum. Why aluminum? Aluminum is widely available, inexpensive, very thin, and easy to apply. With a small piece of aluminum attached by tape or glue to almost anything, it can be detected by this Low Power Non Magnetic Inductive Proximity Sensor. Other low permeability metals such as copper can also be easily detected. This sensor is not to be confused with low cost magnetic sensors which obviously need magnets to operate.

Here’s an interesting open source project on Kickstarter the Re:Load Pro by Nick Johnson of Arachnid Labs:
A constant current load for testing your projects. 6 amps, 60 volts and 25 watts in a workbench-friendly package with a USB interface.
The Re:Load Pro is an active load. It acts as a current sink, always drawing the same amount of current regardless of the voltage across it.
Active loads are incredibly useful for all sorts of electronics testing requirements. You can use one to see how a power supply performs under load, check if a battery lives up to its manufacturer’s specifications for capacity or current draw, test motor drivers, or a variety of common constant-current tasks, such as testing LEDs, or even doing electroplating. With computer control of the load, you can even do your own IV-curve tracing.

High-performance Easy-to-use Mini Power Modules for Makers. Innovative circuitry enables positive/negative supply in one module.
PNMini is a family of high performance, easy-to-use DC/DC Power Modules for DIY electronics.
PNMini can be used as positive supply or negative supply. If both positive and negative supply rail are needed, just connect two PNMini modules together. No hardware changes are required.
PNMini is available in a small PCB package that enhances thermal performance and allows for hand soldering or plugin use. It provides +3.3V/-3.3V, +5V/-5V, or +12V/-12V output directly to your circuits requiring no external components.

The MicroView is the first chip-sized Arduino compatible that lets you see what your Arduino is thinking using a built-in OLED display.
You’ve never seen an Arduino™ compatible like this. With a built-in OLED (Organic Light Emitting Diode Display) you can see what your Arduino is thinking without having to connect it to your computer.
No more cryptic “Hello World” LED blink sequences or shoehorning oversized displays onto your tiny Arduino™. Development is much easier when you can see what’s going on.

Small USB development board for Android. Smartphone powered, USB 2.0 communication, direct connection, open sourced API.
It’s an ARM Cortex-M3 development board that connects directly to your Android smart phone micro USB port. It’s powered from the phone so it has enough power for all sorts of applications without extra batteries, and when the device is connected to the phone the appropriate application starts up automatically.

Watching fireflies is one my most memorable childhood events. Every summer, I would look forward to watching fireflies dance with their seemingly random blinks. I marveled at how a living creature could produce light all on its own. Even today as I share this experience with my children, I look forward to each season of fireflies.
TinyGlo was made to continue the experience of watching fireflies well after the firefly season has ended. Instead of having to wait another year to see them again, you can now bring the firefly like light show into your home and have a similar memorizing light show every evening.

A do-it-yourself Delta Robot kit that’s fun to build, sharp to look at, and a great point of departure for your own project!
Want to make your own delta robot? Do you support the global onslaught of adorable little yellow machines? If you answered yes to either of these questions… then we have the best product to offer you!
The kit includes all of the delta’s mechanical pieces in grey and neon yellow plastic (the yellow fluoresces under black light!), all of the spacers, brackets, ball bearings, and hardware required to assemble them, and the electronic components, PCB and wire harness needed to wire it up and give the delta power.

DSLogic is an interesting open source 200MHz logic analyzer project on Kickstarter.
Most of electronic instruments are designed in professional fashion. They are dedicated, traditional, well functioned, and most importantly, expensive. They are usually only available and affordable to academic and industry. Individuals, however, are not lucky enough to get the best electronic instruments as they want. This is how we are inspired to make DSLogic. [...]
DSLogic consists of DSLogic-Core and extension modules. DSLogic-Core is a re-configurable circuit board based on FPGA technology with maximum 200MHz sampling rate and 64Mbit on-board memory. DSLogic-Core can work alone as a fully functional logic analyzer, along with various extension modules. DSLogic can also work as oscilloscope, data acquisition system, protocol analyzer and even RF analyzer.
