The background bits The proposal for this roadtest plus was written around the TI TPS92512 which is an LED Driver Buck converter. The idea was to design a 4Channel Lighting solution along with a variety of LED panels. In addition to RGB Lighting...
Update: The LEDs I thought broken are still working without head, I can't stop laughing... it's like walking without a head...I think the head dome thing is act as lens and the Würth Elektronik LEDs are hardcore even after the solder heat and...
Traditional reflow systems use a conveyor that physically moves PCBs through various IR heated zones to achieve the desired time versus temperature profile, but this is not well suited to a (very) small prototype operation like my house. In my last b...

Update: I am working on the soldering WE's SMD LEDs with my tricks and ideas. You know what? it really looks cool and works great...but... I don't think I can do the thermal protection with the board I have etched, it seems super hard and as ...
This update in the LED Road Test explores reflow soldering of Würth Elektronik power LEDs. Reflow systems generally try to use a temperature profile to heat the work up to soldering temperature. Here is a plot of a typical thermal profile:This profil...
Update: Ihe kit is gone. Hi, I'm finished with the Ultrasonic Sensing RoadTest, and would like to hand over the evaluation kit to a fellow enthusiast.If you are interested in learning how to measure liquid levels and liquid identification w...
NEW UPDATE: Please check end of the blog post... I am working hard to finish this project lately...Here is the update of my previous schematics and the final PCB design of the board. Instead of 2N2222A BJT transistor I am using ...
This is the last post of this roadtestThe initial idea was to transmit a unique code using the visible light. This has applications in indoor navigation (in museum, shops, etc) I got a working prototype (I will publish a video in the next days),...
Hi,well,,,, i liked write a review, but i got an error message: "unknown error" - i can't find a button "review" ?Unsere Software-Entwickler finden Sie diesen Code dann sinnvoll, wenn sie mit dem Problem befassen müssen: D1449...
In these post I will note down my impressions about the components of the kit I used in my project, namelyMSP430FR4133 LaunchPad Development Kit (MSP-EXP430FR4133MSP-EXP430FR4133)TPS92512 Buck Regulator MSP430FR4133 LaunchPad Development Kit (MS...
This is my proposal for the LED Road Test+ sponsored by element14, Texas Instruments and Würth Elektronik - in case people are curious about what it took to get selected as a participant: LEDs have long been an interest of mine, in fact my first...
After introducing the structure of a camera-based Android application, let’s have a look at the algorithms implemented to decode VLC data smoothThe smooth function applies a moving average to the data captured by the camera according...
While I am working on the PCB of my Smart Headlight circuit design, I got the sparkling idea about thermal protection for Würth Elektronik's LEDs. Würth Elektronik's LEDs has thermal pad contact on their high bright LEDs to control heat dissipation, ...
It took a while for me to post my blog... just had to face some issues and The Christmas celebrations. I have managed to do my schematics of my Smart Headlight circuit. The 3.3 voltage, GND and ADC channel 8 goes through the ST1 scre...
The TDC1000-TDC7200EVMTDC1000-TDC7200EVM evaluation module has 4 main partsThe TDC1000 analog front-end and a pre-programmed MSP430 microcontroller on the board, a 1MHz Piezo Ceramic sensor that plugs into the board and a GUI client for on your...
This is an almost 100% off-topic blog in the TI Ultrasonic Sensing RoadTest series. I'm going to create a KiCad component for the TDC1000 with the KiPart utility. Creating a 28 pin component takes quite some click-and-navigate work with th...
The receiver of the data encoded and transmitted by the MSP430 LaunchPad will be decoded by an Android smartphone running a dedicated appThe app basically captures camera frames in preview mode and analyzes data.In this post, I will talk a litt...
