Today I am proud to announce the winner of the dLight giveaway.
There were 30 participants. I want to thank them for their kind words about my blog. This positive feedback is really important to me and keeps me writing. I was also very pleased with the enthusiasm for the dLights in the reactions. Most people said the dLights were cool. I hope we’ll see some nice applications of the dLights in the future.
The winner of this contest was drawn by my son from a basket containing 30 small papers, each with the name of one of the participants. And the winner is Leon Overweel! Congratulations Leon!
Leon is a talented NXT builder and you might know him from his website World of Mindstorms. I am curious to see what creative uses he’ll come up with.
Today Dexter Industries launched their latest product, an all-color LED called the dLight. I was involved in the development of the dLights so I got them early. I can also give away one set of dLights to one of my readers. More on that later. Let’s take a look at the dLights firs in this video.
I mounted three dLights underneath Agilis, one under each leg pointing to the wheel. I programmed the dLights to give a color that corresponds to the wheel speed of the particular leg. I think the result looks cool.
If you look closely to the sensor ports in the video, you’ll notice that only one is in use. This is one of the great benefits of the dLights, you can daisy chain them. So one free port is all you need to give a robot multiple lights. One set contains four dLights plus the cables to chain them.
As said, I can give away one set of dLights. If you want this set you just have to reply to this message before the first of April.
You’ll find more info about the dLights on the website of Dexter Industries.
Currently I am developing a new sensor that will be on the market this summer. Although I do not want to give away too much details I would like to share some insight in the development process.
Few months ago I got this idea for a new sensor. Something unlike all the sensors that are available today. I think you’ll want it when you see it. I discussed this idea with John from Dexter Industries and we decided to develop the sensor together. As I had a pretty good idea of the functionality of this sensor we could start selecting parts right away. Once we got the part list together John started drawing a schematic for it. From this we ordered some prototype boards. John soldered all the parts on it. I’m still amazed how he did that. Man, these parts are small!
A prototype serves as a proof of concept and also to find any design errors. There are always design errors. In this case we forgot to wire the power line. As a result the prototype was dead. Luckily John managed to add the wiring for the power line and the sensor came to life. It immediately was clear to us that the sensor was what we expected it to be. I wrote a driver for it and started testing. How very nice! My 10 year old son liked it very much, he even built a test device for me.
There are some other small errors on the prototype that are being corrected at the moment. When these are fixed we can start thinking of a first production run. Once this is on its way I will show the sensor to you and organize another giveaway
I’m pretty sure you’ll like our sensor, so stay tuned.
