The PIC32MX250F128B has a myriad of peripheral features that makes this cheap little 28-pin 32-bit microcontroller extremely powerful. However, it does lack a digital-to-analog converter (DAC). A simple approach to digital-to-analog conversion is to...
Techniques ReviewWe are going to consider only time series analysis in this section. There are reviews of "complexity measures" (Feldman and Crutchfield 1998, Daw, et.al. 2002). Kuusela, et.al. (2002) compare the results of ten different complexity measures...
Hardware:Our wide format plotter project got off to a flying start late last year (December 2013) with the main printer framework, electronics and most of the custom software completed within the first three weeks.The next month was spent tweaking both...
Whilst I never really grew up playing pinball machines (arcades are a different story), I had the opportunity to play a full size, fully functioning White Water pinball at my previous job. I was hooked and wanted to keep playing after I came home. Thus...
****PLEASE NOTE: While this system does nothing more than add an additional “button” to open/close the garage and does nothing to defeat the safety IR Beam on the door, I can’t say for sure whether the system is completely safe as the garage...
BackgroundWe modeled a subset of the swarm as individual bees. Each bee had an interal state (dancing, scouting, etc) as described below Each bee is placed randomly on a square region, and does not move while it is with the swarm.Each bee has a discrete...
Greetings fellow Enthusiasts Let me introduce myself. I'm Bones MacGyver. I like to make sparks.I'm going to do my best to help out the community with their battery woes.By no means am I a battery expert. But I have used and abused MANY Ni-Cd cells (and...
The controller uses a simple protocol, which allows an application (robot, etc) to configure exactly what is desired. The robot can request to enable / disable joysticks and buttons, and can adjust the poll frequency and maximum analog transmit...
Since we started, Stubby has grown from a simple, direct-driven 2 DOF (degree of freedom) per leg frame to a mechanically-assisted 3 DOF per leg design with a full inverse kinematics engine (which allows the processor to calculate custom foot positions...
Programming model for Surfaces The method used here is to package each geometric primitive (e.g. sphere) as a Matlab 'struct'. Geometric primitives are then grouped in a 'cell array'. The cell array is ultimately passed to the renderpatch function for...
We all have seen the 3D printers around the world.Well.........I'm feeding this one with steroids!Some technical info:-4 NEMA23 1,7A per coil stepper motors, two on the Z axis-20x20 extrusion Structure, very sturdy-X axis powered on two sides, belt driven...
Current program features: -run a wood stove at a user defined temperature by controlling the stove air damper with a servo-will shut the stove down to a slow burn when the room temperature reaches a user defined setting-incorporates an over temperature...
Ghosh and Jain (1) showed how to charactize a simple, closed, piece-wise linear curve as a Fourier series in a single parametric variable. Such a formulation allows (see Tsow and Land below): interpolation of curves by sampling the parameter more densely.morphing...
