Date: Thursday, June 15, 2000 6:00 PM Subject: John Cole's Mini-Mini Lehman Hello All, I would like to share the good news for those who have been looking for = an inexpensive seismograph to purchase. John Cole of Pearland, Texas, = went to a machinist with his own design for a MIni-Mini Lehman and had = him make up six or eight of the little fellows. John and I live only = ten miles apart and John presented one to me for test purposes. I think = the results have been outstanding. I run mine with a 16 second period = and you can look at my (FC2) recording of the 6.3, 6/11/00, Antarctic = Ridge Earthquake posted on the PSN event list to see the results. John = also presented one to Don Wheeler who lives near Monroe, Louisiana. His = Mini-Mini Lehman recordings are posted as DW2. I think John is = mechanically gifted and he has experimented a great deal with the = Lehman. He is not in this for a profit but only to recover some of the = money used in developing this little machine and for the satisfaction of = knowing he has developed something that could be used in the class room. = He feels strongly that he has a design that could readily be used by = amateur seismologists and by teachers in the public schools and I agree = with John. We both say this with the qualification that the teacher = should not be a complete "klutz." He/she should have a little bit of = mechanical aptitude. I am attaching a picture of the little fellow that = has the footprint of less than two sheets of typing paper. Go to my web = site SEISMOLOGY IN FRIENDSWOOD, TEXAS, USA at: = http://freeweb.pdq.net/fxc/ for more information and an additional = picture. You will find it has some unique features such as a guitar = tuner screw that does away with the akward turnbuckle.
