Chess, Women and Music - Electronics

http://ivan.blogs.chimerical.com.au/category/Electronics.aspx

Programming, like chess, women, and music, has the power to make men happy" - Gerald Weinberg. The standard parallel port pulsing setup in Mach3 uses a set kernel speed (25-100kHz) and this is the rate at which it decides to output a step pulse (or not). It is therefore also the maximum pulsing rate. The implementation details are specific to Mach3, but how would you determine an even pulsing pattern? Is a way to achieve this. This could be expressed as:. Var accumulator = 0.5; loop (X times). 1 12345678...

Cheap FPGA Development Boards | Joel's Compendium of Total Knowledge

https://joelw.id.au/FPGA/CheapFPGADevelopmentBoards

Cheap FPGA Development Boards. Joel's Compendium of Total Knowledge. Cheap FPGA Development Boards. What to look for. I bought Avnet's $49 Spartan 3A development board but it was discontinued not long afterward - right about the time when I decided I needed a few dozen more. I've since done some extensive research (thanks, Google! To find a comparable thrifty thrill. External non-serial memory (DDR/Flash etc.). Things that are relatively easy to add, and are not so much of a big deal to wire up yourself.

Follow Along As I Build a CNC Cutting Table. Vertical and Horizontal Welding Practice Project →. Reconsidering the Electronics…. August 26, 2013. After consulting with folks on WeldingWeb. I’ve redone my trusty electronics comparison chart. A new entry that I was previously unaware of uses Mesa Electronics’. Breakout cards and torch height control with Keling stepper motor drivers. It also uses the open source Linux CNC. Instead of Mach 3. Misc Cables, Switches, Cooling. Included 2 yr Warranty. Sorry, yo...

Random Tech Makings: January 2009

http://randomtechmakings.blogspot.com/2009_01_01_archive.html

Random things I play with; At the moment it seems to be a lot of metalwork, with snippets of electronics and programming. Saturday, January 31, 2009. I bought it from. Bomond Trading Co Pty Ltd. 49 Orchard Rd, Brookvale, NSW 2100. 1/2 inch (12.7mm) ACME threaded rod (aka leadscrew), 10 tpi (10 turns per inch). This is rolled rather than ground so it's less accurate. Wednesday, January 28, 2009. Looking at http:/ www.linengineering.com/site/products/4118.html. And extrapolating a bit, my motor would be so...

On 5 day California/Nevada/Arizona roadtrip. Hydrogen – anderswallin.net. Uniform distribution on unit circle – 蜗牛角上争何事，石火光中寄此生。 On Uniform random points in a circle using polar coordinates. On scipy.stats.chi2.ppf() without scipy. 1,502,263 spam. A new spindle for our Opti CNC mill. Jari has been busy planning and building a new spindle for our CNC mill. The project is now about half-way so I thought I'd take a few pictures and write some text. So far we've been using the stock spindle on the Opti BF20.
