;D
in the works.......
ist
this will consist of the 3 freq gennys bolt sudjuested from jameco i will mod 3 varibale pots like gk i will add my fender tube amp i will add places to monitor the 3 freqs and diffrent outputs i will add 3 small bread boards to the set up for ease of changing caps i will add a powersuply to the unit and also i will add chip sockets to the freq gennyes to allow ease of chip replacement if they blow it will be an all in one tube powered controler board for tpu freq finding and tuneing of coils
like i said the most important tool of all for all tpu researchers!!!!
william
so i have put a few hours in on my rack today and here is a picture with my power supply built in and i mounted 2 bread boards that i had kicking round it is all plexy i love that stuff lol!!! i will keep plugging away at the rack i expect it wont take me long to finish ;D
ist
ah the quiet times ........
so i put more time in on the rack and today my gennys arrive i have decieded to add an extra 12v regulated power supply to the mix it can be used for powering external amps and such this is being designed for much more than just the tpu
so yesterday i studied the schems for the xr 2206 freq gens and i saw that we only need a 4 way switch to change the freq range so i added a switch board to control this i also added 3 outputs for each freq genny and 2 inputs also i added the triangle/sine wave selector switch i will be adding 6 variable pots 3 for freqs and 3 for amplutude
well a pic of where im at with the board
ist
no rest for the wicked !! lol!!
just got my freq gennys so it is back to work on the new toys ;D
well thease kits are kool and easy got the 3 xr gens done and thought i would take a pic because b4 too long verry few will understand what the hell is inside this little box because it will soon get verry harry under there ;D
ist
nice looking setup, looks alot like what giantkiller has going on. keep us posted!
<removed>
hello all
3 freqs are mandotary!!!!
when force feeding and always until we have a poperly built coil then the coil will make the 3rd on its own and then we will only need 2 freqs but!!! if the freqs are as close as i think they are humm......
then maybe just 1 freq genny and a crystal or somthing like it to make the second freq from the first
and dont forget the coil makes the third ;D
ist
just wireing it all up it will take a wile i have decieded to use ribbon wire from a computer to hook it all up because my bottom will swing open to work on the gennys with ease so i will need neat flexable wire and ribbon wire fits
<removed>
what cable?? not sure i follow you corss talk is a bad thing interferince i get that but hummmm....
ok here is a pic b4 i go any further on the wireing will interferience be a problem with the ribbion wire i have chosen ?
please let me know as i do not know if it is a problem i may have a solution i have some cat 5 dirrect bariel sheilded cable but it is a real treat to work with it is gel filled for frost and such cold but if i can avoid working with it then that would be great so some one let me know if it is a must for cables to be sheilded in a set up like this
thanks
it seams somthing is still missing from the mix to have a working ring
now that is assumeing i have the right amp! the right freq gennys! and the right ring but still somthing is missing not the mag eather
now anyone got a guess what is still missing ?!?!?!?!?!?!
i hope so cuz im almost at wits end thinking what is missing the only thing i can come up with is phase!!!!! hummm.... maybe the phase invertor !?!?!?!?!?!
but not so sure just yet
comments??
ist
well i got the ribbon wire done and run but i still have to find 4 more pots 2 of each 1m 50k i added the freq gennys on a hindgs door for easy access a bit more soldering and then it is the freq genny's power supply and it should hooked up in split rail mode like a computer power supply so i will use 1 of those and it will be in an external case to the board
so not that much left on this peice of the puzzel ;D
ist
ok guys
pick her apart lets get this right
rf interferience is a bg problem with what is showen here so....
ideas to fix the problems cat5 dirrect barieal cable sheilded for all siginal carrying wires and they must be grounded so i guess i could use coax but man there are around 75 wires in this mix + so coax ok maybe for some of it
the box the freq gennys should be mounted inside an alum box? to pervent RF interferience? and all wires that carry signal to and from the generator should be grounded to the box and to the power supply? then we could use the gens any where outside the ring and they would not suceptial to interferience? of any kind
and that is the main diffrance between tube generators and ss generators the shielding with tubes we need not worry about the sheilding because interferience is not a problem could that be because the tube is sealed in a vacume? and ss are not
well anyone wanna help me get this thing right? my rack so i can use the ss freq gennys with a tube amp outside the ring or do i have to build a all new tube unit i know i should have done this from the start but here we are
speek up
ist
ok guys
i have gathered my thoughts on this rack it will have to be changed and im happy this was brought to my attention b4 i got too far with it ;D
thank you
now the gennys will be in seperate alum boxes or steel i perfer alum as i work with the stuff so also i will use coax and cat 5 i will still use the knob rack for tuning but will have the freq gennys enclosed in a seperate unit with only shielded wires comming from it to all adjustments and input and output hard to work with but i can do it we can just say my rack just grew in size
well makeing some changes........ any other issues that anyone can see that must be dealt with ??
i cant leave this project and i dont know why??
ist
so i rounded up some more materials for my second atempt at the rack ;D this time with interferience in mind
well gonna put this rack to rest 4 now
i got the sheilded box almost all togather so hopefully there will be no interfeirence when it is compleat it is not as tidy and kool looking as the last 1 but if it works who the hell cares right we want the first public BANG who will do it there is far more than enough info out here to make the first force feeding bang if i can get my shit togather i will try it out
if i was to use ribbon wire inside the steel box will that cause crosstalk between the gennys? i want to use the ribbon for my 4 way selector switch as it needs to bend and cat 5 will be verry difficult to make the bends with out kinking
well back to work on this new box
ist
ding ding
round 2
the new box
almost all ruffed in ;D
hey in looking for a power supply and some rf connectors i just happin to have a wooah!! score ;D i took apart a rca dirrect tv reciever and i found 2 verry nice ferroite rings
1.25" x 5/8" a lot bigger than i have so far
Offset

a posible solution
for offset
or phase what you want to call it
wind 3 trigger winds for the input of the next gen ;D see do you get what i mean or do you want it out right??
hell here it is we have 3 coils of say 5-10 turns to detect when to fire the next coil or sig genny!!!!!! thease coils are located @ 3 diffrent places around the coil but you know what we arnt there yet ;) but soon!!!
ist
so when you first start it then what it is a cat chaseing its tale it will only take a pluse or 2 to start we must bring our siginal out of the center of the ring to close the loop after first or second fire and recycle recycle recycle recycle how??? with our mic of course or is that our balum? hummmm
I meant DC Offset, only important if your doing DC Coupling on the output stage for having a simular Ground, or if you want to offset a signal to more positive or negative when combining

so you speak of the power supply
for the gennys ??
as in a split rail im not right up on all the electronic terms
like 5- gg 5+ i was going to use the ground as sheilding for my siginal carrying wires
i did find a power supply i hope to use for the unit but we will see
ist
the outputs of this supply are
+3.3
+3.3
+12
+5
+5
gnd
gnd
gnd
+22
-5
i was gonna try the +5v gnd -5v to power my generators if no luck i will keep looking i have quite a pile of stuff kicking around this place kinda of wish i i never threw out those 30 sat recievers i had for forever but you always need it after the fact :)
a question for all the smart guys here
lets look at cat 5 ethenet cable
if you notice they are twisted in pairs then sheilded when i was installing wireless internet i was told that there were less losses in siginal when the wires were paired and twisted
so my question is this can i use a twisted pair of cat 5 1 wire for siginal and the other as sheilding 1?!?!?!?! this is for inside of my box only all out side connections are made with coax input output test and read points there 19 external connections on my box 13 output points and 6 input
ist
i dont see how i could go wrong useing cat 5 inside my box the more sheilding the btter ;)
oops is that some kinda of secreat hummmm!!!! well for results in the force feeding part yes it is when useing ss outside of the ring with a tube amp yes this is not the right path :( not the way sm wants :( it makes me sad that i have to do it this way but here we are but just cuz i want to keep it real!!! i will do tubes too as i get more money to play with when i am compleatly finished this project i will totaly understand each and every aspact of this unit :) and that makes me happy then i will teach it to those that want to learn it to better them selvs and save a few bucks
but those of you that want to do it the right way like sm would like please use tubes the path will be easy for your scucess ;)
why do you think we need to use tubes!?!?!?!?!?!
We're not likely to ever re-engineer the T.P.U. without first starting with tubes as SM suggested.
I think you won't see anything useful without floating grounds. Common grounds kill O.U.
the main part of my mess is a tube powered amp as i think and know ss gennys can be used and well they are used but extra mesures will have to be taken to get it to work so if i have no luck with ss in my early tests no loss i will do tubes as well
ist
here is a layout drawing of the freq genny i am currently wireing
ist
The ECD is a floating ground design and produces dangerous output using solid state digital input.
--giantkiller.
been busy soldering still a bunch to do but almost there :)
ist
back at it .......... now only 27 more wires :)
as you can see i left lots of room inside the cd rom cases well so i can add aditinal sheilding if need be like if i have to encase each freq genny seperatly in a tin box and add more or better sheilded wires in this box to get this to work i was also of thinking of putting the whole thing in a sat case after i get it producing perfetc sine waves with no interferience from the coil so....
why will we get inter ferience from the coil? well what do tubes do diffrently ? why wont soild state work outside the ring ? hummmmm
why must our ss controld be inside the ring and the sencitive ones be in the center of the ring? well in the center of the ring the verry center there will be no flux am i wrong? ok so if there is no flux then there will be no interferience and even if there was flux or is flux than if it was sheilded it really wouldnt matter right
so tubes and ss what is the diff? well this is only a thought i have no idea if this correct but magnetics!!
ss will fail with high magnetics tubes do not no?
ist
ran out of solder the other day got some more today so i hope to finish the wireing tonight lastnight i noticed on my scope i have a built in 12v offset power supply ;D so no need to serch for one of those
all wired and soldered just some small wires on the pots left im still short 4 pots i may have to solder the surrface mount ones in to get them running and setup
the mess heres the pic
ist
you guys finish it!! cuz i aint!!
