Good morning all

@ Jb

no my reed do not arc.

are your diodes the right direction ? my voltage is very low , about 1.2 to 1.6 volt and current very low too. On previous test by using 4.5 volt battery , without protecting diode , the reed does arc and will not work long because than it became black in the center and than it glued itself and stop working.

@ 4Tesla

Thanks and please feel free to do one of those it is a very interesting machine.

For info Yesterday evening i could not prevent to make a test before sleeping. So i took back the AA non rechargeable battery (originally 1.5 volt) which run my previous test for more than 18 hours and was at 1.2 volt . After one day rest this battery went up to 1,26 volt. I use it for the new test.

so 1.26 volt yesterday 23.30  at 46 rpm. And this morning after 9 hours the rpm are 25 and the battery is at 1.24 volt. For my very crude proto i think it is very interesting. An as i mentionned in my previous post the reed switch must be very fine tuned, and it is not my case at the present. And another problem is that the reed are magnetic and they make a braking cogging when the magnet bypass. Is it an other mean to get the effect without reed ?? Is there a difference between reed switch (tube) and reed relay as Ossie seams to use in is design ??

To most of the "replicants" - you still do have BEMF - so it will not work ;]

DOH! Thanks that is what I wanted to know, I'll reduce the voltage.

Hi All,

Please see the excellent replication work of Jean-Louis Naudin as follows:

Back in 2007, Sean gave a presentation To University College Dublin (UCD)

At the very end of the first video (last 10 seconds), http://www.youtube.com/watch?v=nqoZWaK4AtY , Sean says it's not really an engineering problem, but is a problem with "tape price".

I'm not sure if he said "tape price" or something else.  If I understood him correctly, then what could he be referring to as "tape price".  Could he be referring to a tape wound core?

I'm in Ireland so the accent is more familiar to me. I believe he says "tape drives" referring to a magnetic effect being noticed before in old fashioned tape drives.
