Not Just Arduino-talks
Back to Not Just Arduino page
This is a "wish list" of topics our members would like to hear about. If you want to come talk to the group or if you are just interested into attending a session please add your name on the page. The format is up to you, it could be a very short presentation or a more hands-on demo. Sessions are open to everyone.
Below are a few examples of topics about power control and design in low voltage circuits, I'm sure some of them overlap. Feel free to add more talks and leave some comments.
|The mathematics of electronics, Watts, Ohms, Farads, Coulombs, Amperes, Volts||Paul Maidment, Bradley Wood, Matt Wheeler, James Cadman||Ohms law; resistors, capacitors in series and parallel; Kirchhoff's laws, Power equations.|
|How to measure, control and limit current||Paul Maidment| Bradley Wood, James Cadman||This is quite a big area: from basic resistor usage, to transistors, mosfets, relays, triacs, etc. Might be worth splitting out into sub-sections. -- Bradwood (talk)|
|How to design for the power requirements of your circuit/project||Paul Maidment| Bradley Wood, James Cadman||.|
|How to design your project for lower power usage||Paul Maidment| Bradley Wood, James Cadman||.|
|How to reduce power consumption via programming (applies to most microcontrollers)||Paul Maidment| Bradley Wood, James Cadman||would be nice to cover the ATMEL's uC's SLEEP capabilities. -- Bradwood (talk)|
|OpAmps -- what they are, with practical examples||Bradley Wood, James Cadman||.|
|Wearables 101||?||Bradley Wood, James Cadman||Lilypad, Flora, handling conductive materials, power, etc|
|Filter circuitry -- what they are and why you might want one||Bradley Wood, James Cadman||Low Pass, Band Pass, High Pass, etc, etc.|
|Accelerometers -- tips and tricks for dealing with them||Bradley Wood||Bradley Wood, James Cadman||Setting range and frequency. Calibration. High or Low pass filtering. Sensing tap, tilt, freefall, etc, etc. Accelerometers in the context of other IMUs and DoFs. Sensor Fusion. Kalman filters|
|Low-level ATMEGA overview||Mentar (not expert, just using it for the robot arm)||Bradley Wood, James Cadman||Timer0, 1, etc. Interrupt Pins, and writing ISRs, Hardware overview and onboard capabilities (i2c, spi, pwm, etc, etc). Interesting registers, how you might manipulate them, and why. Basically -- a synopsis of the ATMEGA328P data sheet in a nice digestable format.|
