I am an old retired person, formerly a mechanical designer, mostly process, packaging and assembly machinery. No experience with consumer products, robots, toys, mobile stuff or electronic circuitry. I am currently a member of the Yahoo beam discussion group and have contributed a few suggestions for mechanisms, but mostly just "listen" to discussions about nervous network circuitry problems and try to absorb a bit of it. I am also interested in piezoelectric devices without knowing much about it and corresponded for a while with Dr. David Pearce while he was doing development at University of Birmingham and later while he was employed by 1 limited, a development and licensing company that has developed a piezoelectric sound projector and a piezoelectric lens focusing device for miniature electronic cameras of the type used in cell phones and R/C models. My reason for wanting an account on ROBOTS.NET is to find people that might be interested in developing kit toys to use the Elliptec piezoelectric motor. I am not trying to sell anything to anyone, but might be able to contribute notions for modular components and some mechanisms that could be driven by motors of this kind.
Recent blog entries by Frank McNeill
I finally found a way to get a free web site, thanks to information on a diary entry by Scienceboy2. The web site is still a blank page because I'm still trying to learn how to develop it.
Meanwhile, I have done what hermit crabs do by moving into an shell on Yahoo Groups. To find an empty shell, select a group category and go down toward the end where there are groups without any members, messages, files, photos, or links.
Although not very religious, I went to the end of a list for "religion" to find an empty shell at: http://groups.yahoo.com/group/ina56e/ to add files. The subjects of the pdfs are: (bamboo ship models and pop-pop boats) (some mechanisms for bug legs) (dome-shaped houses) (tube-shaped houses) (piezoelectric stuff) and (insect flight mechanisms)
Anybody who is interested in these things is invited to download files.It will be necessary to join as a member, which will take a minute or less. If you decide to "unjoin" just click on an e-mail address that will be sent to your mailbox as an automatic message from a moderator.
Best wishes to all, Frank
Spent, or misspent most of the afternoon trying to set up a Yahoo freebie website that went well until I tried to upload a file to it and caused my little iMac to freeze. Restarted and went through the same drill several times with the same results‧' f r e e z e and r e s t a r t. Talk about the frustrum of a cone, which is nothing compared to the frustrum of a conehead like me.
I couldn't even find a delete button to dispose of the wreckage which is probably floating around on a server somewhere as an electronic Sargasso Sea crowded with abandoned and broken websites.
I wanted to put up several files with sketches and descriptions of notions I've come up with over the years but wasn't able to do this today. Meanwhile anybody that would like to see sketches, etc. of an "improved Lego brick" with a positive attachment feature and several versions of a gearmotor based on the motion of a wobbling coin can either ask for a file that could be sent as an e-mail attachment, or sign onto of beam robotics at: http://groups.yahoo.com/group/beam/ in order to go to the files section for one titled buglegz.pdf with stuff about a mechanism cobbled together from a "Swedish wheel" and a smiley face for generation of a "D" shaped path to drive various pantograph linkages for articulated legs that could be driven by a reversible gearmotor. Two reversible gearmotors could drive four, six, eight or more legs per side.
There is also a "leg path generation.jpg" schematic that was added as an after thought: and a "good vibrations.pdf" that's mostly about stuff batted back and forth by David Pearce, a piezoelectrics whizz kid who was a research scientist at University of Birmingham when the exchange began and a product development guy at 1Limited, a development and licensing company until David decided to leave and pursue another career. Some of the helimorph-based products David helped develop will eventually become stuff that can be picked over for the construction of piezo-junkbots.
Meanwhile, I hope somebody will develop a small driver for Elliptec resonating motors that could be used in kits based on the use of improved Lego brick things described in a file with sketches and descriptions of wobbler gearmotors with the title "wobblers.pdf" There's also stuff about an articulated arm that could be driven by three gearmotors, servos or hydraulic rotary actuators and some other stuff that somebody might have a use for.
I tried to stir up interest amongst the beamsters in notions for hotbotics devices based on equipping little metal "pop-pop" boats with servos for rudder control. These little boats sold for a buck or less before WW2 when I was still a kid, but seem to have disappeared during the war, or shortly afterwards.
There are still a few shops in India and China that make them and several dealers in the US and elsewhere that peddle them if anybody wants to buy one. One possibility would be to use a thermoelectric generator instead of a battery. I will put some sketches and descriptions together for anybody that is interested in notions for little metal steamboats that might be rigged for robotic or R/C control.
