0-10V Volt monitor project has been designed around LM3914 IC, It is an easy and less expensive project which instantly visualizes voltage level. The project is based on the popular LM3194 IC from Texas instruments. Handy 0-10V DC Voltmeter can be used as a voltage tester.
The LM3914 senses the voltage level at the input pin and drives the 10 light emitting diodes based on the voltage detected on input connector. Circuit works on 12V DC. J1 Jumper is used to select the DOT mode or bar graph mode.

This project provides you a simple and easy solution to connect / convert your Microcontroller input/output to be connected to the serial port of the Computer.
This projects build around popular MAX232 level shifter IC to do the Level Shifting (Voltage) between 5 V and 12 V DC.
An Onboard 9 pin female D connects this PCB to the Serial Port cable (not supplied with the Kit). Connector J1 connects to the Host for power supply and serial In/Out signals.
A Provides data from the Computer to the Host (RXD)
B Provides data to be sent to the Computer from the Host (TXD)

Using Part-Sim we can verify the response of this RL circuit, and our calculations for the initial, final, and the transition between those conditions. While analyzing this circuit’s response on paper and in Part-Sim, we must use the initial conditions (time and V) and component values. In Part-Sim setting up the switch is the hardest part; with the simulation requiring set up of a voltage controlled switch and AC source with a pulse to get the correct behavior in the circuit. Web based Part-Sim allows you to simulate and verify your calculations any time.

EAGLE users have long asked for a simple 3D export that would allow them to cross their designs from the electrical realm into the mechanical realm. The current crop of solutions have suffered from either limited applicability or generated a format that wasn’t widely accepted among mechanical CAD tools. The purpose of this blog post is to inform users of a new tool that can finally fulfill this long requested need.
CadSoft has partnered with SimplifiedSolutions Inc. to create the IDF-to-3D tool.

This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30 minutes without changes and a bluetooth connection to control the lamp with a smartphone or tablet. So, if you continue reading the post, you’ll see what we develop!

Following on from the release of their PSoC 4 BLE chip at the Electronica Exhibition last year, Cypress Semiconductor Corp are extending their play in the Bluetooth market with the introduction of their new EZ-BLE module. The module contains the PSoC 4 BLE chip together with two crystals, an on-board chip antenna, RF shielding and passive components, all in a compact 10 mm x 10 mm x 1.8 mm form factor so that designers using the module can apply to add the Bluetooth logo on their products by referring to Cypress’s Qualification Design Identification (QDID) 67366, a unique serial number assigned by the Bluetooth SIG. The module is compliant with wireless regulatory standards in the U.S., Canada, Japan, Korea and Europe and offers a significant saving for designers in development, testing and certification costs.
