RobotShop Acquires LetsMakeRobots.com

RobotShop.com announced today the acquisition of Let's Make Robots (LMR), a website that brings together the world's largest community of robot makers and enthusiasts.

RobotShop, the leading source for robots and robot parts on the web already hosts one of the largest communities of robot and drone enthusiasts. In 2010, in order to better serve their community by providing free information and articles accessible to all, RobotShop acquired GoRobotics.net, one of the most popular and oldest blogs on robots. GoRobotics has since been fully integrated with the RobotShop community and is considered the #1 source of knowledge in robotics for robot lovers. Following the acquisition of Lynxmotion in 2012, a pioneer of educational robotics since 1995, Lynxmotion.net, one of the most vibrant forums of the early days of robotics development was also integrated with the RobotShop community, providing a single platform for all robotics enthusiasts to share knowledge and projects.

“RobotShop exists in order to serve makers and users of robots. It's our community and our customers that allow us to become better every day.” said Mario Tremblay, CEO of RobotShop. “We plan to work with members of the LMR community to provide all the tools, features, privileges and resources to enable them to create, innovate, share, inspire, and even be recognized and be paid for their input and contributions. In this sense, we have a multitude of ideas, projects and programs that we want to put in place, but we will first and foremost listen, communicate and take into consideration the opinions and desires of the LMR and RobotShop communities. Together we will build robots and push the evolution even further.”

LMR was founded in 2008 by Danish tech-wiz, Frits Lyneborg and is undoubtedly the #1 hobby robotics community. LMR includes a variety of features including robot profiles, a blog, forum, product reviews, challenges, a "Chill out" area as well as a real time public chat for members that is present throughout the platform. Recently a Beta marketplace was put in place that allows members to buy and sell new and used parts between users. LetsMakeRobots is animated by a spirit of friendship and the place has become a favorite gathering for the most brilliant, ingenious and creative “geeks” and “nerds”.

“The Lets Make Robots project has been a large part of my life for the last 7 years. I cannot count how many friends I have made though the site, and it’s hard to put words on the spirit of ‘togetherness’ that seems to live by itself within the members of LMR.” Indicates Frits Lyneborg, creator of Let's Make Robots. “What started out as a few friends, has turned into a global community with an absolutely enormous amount of data and daily visits, very difficult to manage by a small team. What RobotShop offers is a solid base and I’m confident that with a strong partner that has a genuine interest in all things robotics, the Let’s Make Robots community will be able to flourish and expand.”

If you want to create the 100 watt OCL audio amplifier circuit. I want you to consider this circuit as one. It uses STK4231 IC products to create a simple, small and best economical.

How it works.
The STK4231 is Hybrid IC of Sanyo, in the family of STK4201II. Can provide a high power output to 100 watts per channel. And When connected to the bridge adapter with output altitude of about 400 watts is incredible.
-Built-in muting circuit to cut off various kinds of pop noise.
Greatly reduced heat sink-due to case temperature 125 degrees Celsius.
-Excellent cost performance.
As this circuit, we can design the OCL amplifier 100 watts each channel. Will see that, this circuit consists of only a few external components.
-The capacitor C9,C10 is used to reduce noise at high frequencies.
