  1. Dear, this is a tiny MCU which I designed by myself. I also create an ARM controller for 4 servo motors or all types of LEGO motors. I hope to get your suggestion.
  2. Watch the Footage A colourful pixel is two or more tiny LEDs with different colour put very closely. When some LEDs are on, others are off, or all are on, you will see a different colour thinking it is only one pixel. What a romantic time when coming across the colourful pixel in an Ice-cream Van under Arthur's Seat in Edinburgh!

    [MOC] Vinyl, Turntable and Phono

    Thank you so much! We will be great friends! Maybe making old things resurgent is a way of creation.
  4. Watch Footage With the resurgence of vinyl over the last several years, a whole new generation is getting into turntables. Turntable Cartridge Moving Magnet Moving Coil Moving Iron A look at vinyl record grooves at around 1000x magnification. You can see the waveforms of the music itself… Vinyl Diameter:12”;10”;7”. Rotational Speed:8-1/3 rpm;16-2/3 rpm;33-1/3 rpm;45 rpm;78 rpm. Time Capacity:LP[Long Playing] with 12” and 33-1/3 rpm;SP [Single Play] with 10” and 78 rpm or 7” and 45rpm;EP [Extended Play] with 12” and 33-1/3rpm or 7” and 45rpm. Reproductive Quality or Level of Fidelity:high-fidelity;orthophonic;full-range. The number of Audio Channels:Mono;Stereo;Quad. Internet of Things Controller Music, after all, is something that brings joy to our lives. Vinyl gives us a way to increase the joy factor and explore music in new and exciting ways. That joy is the essence of the vinyl revival. It’s why people are gleefully purchasing records again. Copyright © Camellia Café 2016-2021 Camellia Café and its LOGO are registered trademarks.

  5. Wonderful! Awesome! Both your idea and art products are interesting to me. Dear, I agree with your idea. The old fashion computer has it's value. It is a fundamental tool for children learning computer knowledge, such as binary and Ascii. Besides, when quantum mechanics computers are coming, old fashion computer will give a transparent compare between classic computers and quantum mechanics computers. What’s incredible is, I have a similar experience with you. Learning and working in both the electricity and the chemical industry. Just do as you wish! You are not old. You have a young spirit and positive thought. You will have great success!
  6. Thanks so much for your encouragement. Besides, it is not based on Arduino. I designed an MCU with lego motor control functions and the Internet Of Things(MQTT) in this model. Let's enjoy LEGO jointly! Bingo! Sannner is also a big screen. Thank you!
  7. Watch Footage ASCII Code Binary Operation We don't fear Coronavirus, We have masks, We have the vaccine, What's more important, We have hope. Happy Chinese OX Years! Copyright © Camellia Café 2016-2021 Camellia Café and its LOGO are registered trademarks. Please kindly visit Camellia Café

    [MOC] Motorcycle with Sidecar

    Thanks for getting your message. You are right. It is based on Creator. I also put a chip into it. It has functions for Internet of Things. I can drive it from a mobile phone via Wi-Fi or 4G. Thanks for your suggestions.
  9. Sidecars are a great way to enjoy a motorcycle. One can carry items safer than they could be compared to being on two wheels. + Steering + Differential and Locking + 2 Cylinders Engine + LED Light Camellia Café presents a particular designed Motorcycle with Sidecar model being controlled by Mini controller. One steering servo motor is used to steer. One DC motor is used to as power. Wi-Fi technology is used to control this model via the local wireless network. MQTT technology is used to control this model via a wide wireless network, then, you and your children could manipulate this model anywhere with iOS, Android or Windows Devices.

    [MOC] Beemo with Touchscreen HMI

    Haha, thank you so much! Please watch my video on Youtube. I want to make a still Droid with a touchscreen. He could control LEGO motors with a display screen. It is original from BOM(Beemo) in comics Adventure Time.
  11. Please kindly watch on YouTube! A touchscreen is one of Human-Machine Interface. It is an input device and normally layered on the top of an electronic visual display of an information processing system. A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, keyboard, or other such.
  12. Please kindly watch this video:
  13. Camellia Café MCU (Micro Control Unit) gives children or students initial knowledge of Electronics. In Camellia Café MCU Laboratory, you will get basic knowledge of Electronics, Mechanisms and Software programming. Servo motor is widely used as an actuator of autonomous cars, robots and droids. A Servo Motor is a self-close loop. But only have a high performance motor is not enough. The motor-driven chips, encoder and algorithm play important roles. All keep servo motor with high accuracy in speed / torque, degree / position, time period feedback control. With Wifi Bluetooth/BLE and Cellular, it will be feasible to manipulate them from PCs, Pads and phones. What’s more, this make it easy to connect to Internet and Cloud Database. Mechanism is the body of Autonomous Cars, Robots and Droids. It is the mechanism that fulfills the movement. Gear, Belt or Chain and Linkage are three major transmission mechanisms. This is a simple gear transmission. Due to different teeth of these gears, the speed is reduced with torque increased. Chain or belt is another type movement transmission. It could transmit movement in a long distance. Worm gear is a special gear. It can only transmit from worm to spur. The reverse is infeasible. Linkage is a third type of movement transmission. Crosshead is another key element. However, we are familiar with numbers and letters. Only with Binary, it is hard for a robot to communication with us. It is the ASCII code that instructs a robot to recognize or display letters. Program, or called Code, is the body of the algorithm. It is the program and code that instruct Autonomous Cars, Robots and Droids to perform their action. No matter Assembly Language, or Objective Oriented / Procedure Oriented Language; no matter C, C++, Basic, Java, or Visual C++, C#, even Swift, Python… Don’t worry about so many types of platforms and codes. If you master one of them, you will be familiar with others. When working, you only need to decide which code language is asked as the hardware / platform requires and as your preference, even new type code is coming, after learning in a very short time, you will get that new and get done with your program. Different hardware and different platforms support different code languages. Some hardware such as the controller MCU in Camellia Café Model uses language which is very close to C. Windows support a lot of languages, C, C++, C# and Visual C++ are fittest. Visual Studio is their develop tool. Android (based on Linux) phones and pads use Java. And the develop tool is Android Studio. iOS or Mac OS (based on Unix) which is in your iPhones, iPads or Macs use Objective-C or Swift. Their develop tool is Xcode. Welcome to Camellia Café !
  14. Delta Robot is one of Parallel Robot: Parallel robot uses several serial chains to support a single platform, or end-effector. The end effector (hand) of this linkage (arm) is directly connected to its base by a number of separate and independent linkages working simultaneously. A Parallel robot arm is designed so that each chain is usually short, simple and can thus be rigid against unwanted movement. The off-axis flexibility of a joint is also constrained by the effect of the other chains. Errors in one chain's positioning are averaged in conjunction with the others. A further advantage of the Parallel robot arm is that the heavy actuators may often be centrally mounted on a single base platform. This reduction in mass along the arm permits a lighter arm construction, thus lighter actuators and faster movements. This centralisation of mass also reduces the robot's overall moment of inertia. A drawback of Parallel robot arm is their limited work space. Another drawback of Parallel robot arm is their nonlinear behavior: the command which is needed for getting a linear or a circular movement of the end-effector depends dramatically on the location in the work space and does not vary linearly during the movement.
  15. 6 Axes Robotic Arm is a Serial Robot Arm. Serial robot arm is designed as a series of links connected by motor-actuated joints that extend from a base to an end-effector. It has a large workspace with respect to the size of the robot and the floor space it occupies. However, as Serial robot arm is an open kinematic structure, it has the low stiffness. And its errors are accumulated and amplified from link to link. It also needs a perfect counterbalance design to carry and move the large weight of most of the actuators. 1. Yellow: this servo motor is the first axes. It rotates from -180 degree to +180 degree in the horizonal plane. 2. Green: this motor is the second axes. It rotates from -45 degree to +30 degree in the vertical plane to make the robot arm move forward or backward. 3. Blue: this motor is the third axes. It rotates from -15 degree to +30 degree in the vertical plane to make the robot arm move upward or downward. 4. Red: this servo motor is the fourth axes. It rotates from 0 degree to 360 degree to make the robot arm spin. 5. Orange: this servo motor is the fifth axes. It rotates from -90 degree to +90 degree in the vertical plane to swing the robot wrist. 6. Purple: this servo motor is the sixth axes. It rotates from 0 degree to 360 degree to make the robot wrist spin. Counterbalance There are four ways of counterbalance: 1) Counterweight, 2) Springs, 3) Balanced links and 4) Pneumatic cylinder. A gyroscope can be used to sense the tile of the robot or droid, the controller then predict trends of unbalance, and adjust counterbalance system. ARM Controller Camellia Café ARM Controller controls 8 Servo Motors or DC Motors. Just enjoy it! Camellia Café
