Pretty clean CDROM CNC build

Posted on October 31, 2016 by robertwilkie

This has to be one of the cleaner looking builds of a CNC with CDROM motors.  Not so sure about the $10 cost bit.  Servo is $1-2, arduino nano can be another $6-8, and L293D are another $3 each. http://hackedgadgets.com/2016/10/28/diy-cheap-cnc-machine-using-dvd-drives/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+HackedGadgets+%28Hacked+Gadgets%29

Xerox shrank 5.4% in 10 months in Rochester NY

Posted on October 31, 2016 by robertwilkie

Around 300-400 people roughly.  Since a layoff of that size would have made news easy, Xerox must have been having lots of little layoffs over the past 10 months to reduce staff. http://www.democratandchronicle.com/story/money/business/2016/10/28/xerox-cuts-345-jobs-rochester-area-2016/92902066/

Retro-fitting a smoke detector

Posted on October 28, 2016 by robertwilkie

Interesting build.  They author basically is adding bluetooth support to the smoke detector, the trigger is the pull on the battery when the alarm goes off.  Me…I would use an ESP2866 instead (just as cheap and wifi) and TI….well I … Continue reading →

Posted on October 28, 2016 by robertwilkie

Yes I know you can get a tester for $5, but this one is stuck to the rear window so you can see it while in the car.  Only thing I would do differently is to have a bypass on … Continue reading →

Nice Homemade plotter

Posted on October 28, 2016 by robertwilkie

Pretty nice plotter build.  I am surpised the author just  didn’t use the base of an old inkjet printer instead.  But whatever works right.  I like the bluetooth add on too. http://www.instructables.com/id/CNC-Drum-Plotter/

bike wheel with spoons to generate power

Posted on October 27, 2016 by robertwilkie

This was too funny.  I like the simple way of fastening the spoons on.  Not so sure I would waste a bike wheel hub on this, but maybe a gear to a motor system?   Wait he spent $60 for the … Continue reading →
