Some new cool robotics hardware to check out!

We are now selling our custom robot slewing bearings individually for those who need them. They come in two sizes, 120mm slewing bearing or 140mm slewing bearing.

Do you need to mount stuff, possibly your PCBs? Pick up our Metric Nut and Bolt Variety Pack or the Standoff Variety Pack to help.

Finally, we have our gooseneck solution for mounting cameras on robot arms or for mounting stationary cameras or sensors. Goosenecks are awesome for quick and easy positioning without having to build complex custom mounts for each situation.

200 watts home power inverter project using SG3526N

Posted: 08 Jun 2013 01:42 AM PDT

the-protection-circuit-of-200-watts-home-power-inverter

I’m been talking about the the 200 watts home power inverter projects many articles. Include the following article. 1. Simple working principle of the inverters 2. Operation of 200 watt inverter diagram 3. An oscillator of the 200 watts power inverter 4.The output circuit of 200 watts home power inverter. Today we see the protection circuit. Which is divided into three parts are: 1. the overload output current protection circuit, 2. The output overheat temperature protection circuit 3. the Battery checker. If there is malfunction occurs. The protection circuits have to stop the operation of IC2-SG3526N. Which is the frequency generator to stop the output transistors. As prevent damage that may have occurred. In addition, also has check circuit voltage from battery that is the power supply to the circuit. All checks will stop the the circuit. And diplay with the D1-LED. 1. the overload output current protection circuit have [...]

RK-1, a wifi Arduino mobile robot for iOS & Android devices

Posted: 05 Jun 2013 09:51 AM PDT

Today’s Kickstarter shout out is for RK-1, an adorable wifi arduino bot to be controlled by smart phones and tablet devices.

From the project page:

The RK-1 is a fun mobile robot, that uses an ad hoc wifi connection, which is controlled using your iOS or Android device.

The control board on the robot is built on the Arduino hardware/software architecture, which is open source, and the controller software and hardware will also be available open source. The idea is to give the community the ability to make Arduino projects mobile. There is no end to what you can do- you can add sensors and actuators to this fun little device and control it remotely.

I have implemented a new and amazing way of controlling the robot using swipe gestures.

1 MHz time base using ceramic filter 10.7Mhz

Posted: 05 Jun 2013 11:43 PM PDT

Normally in micro computer system will use a crystal as frequency generator. Although now the crystal will be cheap down. But then still is an expensive components,when compared to other devices. And I like to modify the electronic devices that remove from the old PCB to reused always. Because it enables us to save. And reduce environmental problems as well. I checked the old board about radio receivers. usually found one interesting device is a ceramic filters. It could replace the crystal. Help us to save, and electronic skills also improved. In the production of high frequency. Digit numbers behind Of frequencies is rarely important. However, the need for precision is stability. Which the ceramic filters has this feature. From circuit As circuit shown can Can produce precisely the frequency of 1.07 Mhz Therefore, applied to micro-processor. The circuit consists of the generators section are N1,N2,P1,R1 and ceramic filters. The [...]
