Servo (Radio Control)

Servos (also RC servos) are small, cheap, mass-produced servomotors or other actuators used for radio control and small-scale robotics.
Radio control servos are connected through a standard three-wire connection: two wires for a DC power supply and one for control, carrying a pulse-width modulation (PWM) signal. Each servo has a separate connection and PWM signal from the radio control receiver. This signal is easily generated by simple electronics, or by microcontrollers such as the Arduino. This, together with their low-cost, has led to their wide adoption for robotics and physical computing.

Small Stepper Motor

Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3D printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use. These small steppers are a great way to get things moving, especially when positioning and repeatability is a concern. This is a Bipolar motor.

Pros

Excellent position accuracy
High holding torque
High reliability
Most steppers come in standard sizes

Cons

Small step distance limits top speed
It’s possible to “skip” steps with high loads
Draws maximum current constantly

PIR Motion Sensor

Passive infrared (PIR) sensors are motion-detecting devices used in security systems across the world, even though you may not see them, they probably see you.

This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low.

Pololu Adjustable Boost Regulator 2.5-9.5V

This powerful, adjustable boost regulator can generate an output voltage as high as 9.5 V from an input voltage as low as 1.5 V, all in a compact, 0.42″ x 0.88″ x 0.23″ package. A trimmer potentiometer lets you set the boost regulator’s output voltage to a value between 2.5 and 9.5 V.

Lithium Ion Battery – 2.5Ah

These are very slim, extremely light weight batteries based on Lithium Ion chemistry. Each cell outputs a nominal 3.7V at 2500mAh. Comes terminated with a standard 2-pin JST-PH connector – 2mm spacing between pins. These batteries require special charging. Do not attempt to charge these with anything but a specialized Lithium Polymer charger.

EMF Meter

EMF measurements are measurements of ambient electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics. In fact probes should not perturb the electromagnetic field and must prevent coupling and reflection as much as possible in order to obtain precise results.

EMF probes may respond to fields only on one axis. Amplified, active, probes can improve measurement precision and sensitivity but their active components may limit their speed of response.

ADXL335 Triple Axis Accelerometer

Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors – the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption – only 320uA! The sensor has a full sensing range of +/-3g.

Project #1 – The AcceleroSynth – Mk1

Apr 3, 2012 @ 15:03


We are finally ready for our first electronics project, The AcceleroSynth. It is an microcontroller-based (Arduino) music synth that is controller by a 3 axis analog accelerometer. It will be both a hardware and a software synth. This is the announcement for the project and in the coming days I will post the BOM (Bill of Material), schematics and Arduino code with the first assembly video. The project will first be assembled on a protoboard, then a soldered version will be built either on a perfboard or on an Arduino ProtoShield. If there is enough demand either a PCB or an Arduino Shield will be built for the project and sold here. More on that later. The first installment on the building of the project should be up on a few days.
