  • Theremin World - Topic: Goals for a TW Theremin
    the EW adjusts the reference oscillator and this is not the best place to do this Fred s idea tunes the antenna circuit which is better Keeping adjustments to a minimum has always been preferable The important adjustments are setting the pitch and volume oscillators to the resonant frequency of their antennas and can be done with an RF probe and volt meter Very easy to build and use One of the goals of this project is learning how a heterodyning instrument works I think documentation is at least as important as circuit design If the builder understands how the antenna circuit interacts with the oscillator tuning will be much more intuitive High gain in an oscillator is both a blessing and a curse The currents in a resonant circuit are much higher than in the bits driving it This can lead to instability due to component heating surprisingly fast even in low powered circuits The goal is just enough gain for reliable operation Uncle Bob s EW oscillator has a lot going for it but obviously we don t want to rip it off There are plenty of other proven designs although I think it would be best to avoid taped inductors Higher frequency s do require smaller linearizing inductors There are compromises The linearizing inductor forms a series resonant circuit with the antenna and hand capacitance As we move up in frequency the inductance needed goes down but the antenna capacitance says the same therefore the pitch range goes up because the ratio between L and C is greater Higher frequency more octaves If we go too high we run into the AM broadcast band A theremin operating on the same frequency as a 10 000 watt transmitter would not be a happy thing I don t think we can eliminate linearizing inductors To be playable a series resonant antenna circuit is needed Rob link Report Post Posted 9 28 2012 5 34 14 PM 7 dewster From Northern NJ USA Joined 2 17 2012 threads posts w0ttm good points I m hoping we could think outside the box a bit for this project Is there really no way to avoid adjustable inductors and capacitors The EWS has multiple interacting adjustments inside and outside too many really I d like to just turn it on and have the pitch and volume sections in the same state they were last and not have to adjust it at all other than for brightness tone etc Some retreading of past designs is unavoidable but borrow too much and one finds oneself on the same roads making pretty much the same decisions that everyone else has That may or may not produce a simple robust responsive and easy to build design but it is a rather uninspiring process IMO If we tried higher frequencies we might run into whatever the heck is going on in RS Theremin s designs link Report Post Posted 9 28 2012 6 55 32 PM 8 w0ttm

    that the position of this additional pole in the curve can be adjusted Dewster are you up for v2 of your simulator Btw in practice jumping to the 2nd resonant frequency which is the lower one occurs only when the self resonant frequency of the series circuit by linearization coil s and the antenna is greater or equal the self resonant frequency of the oscillators tank circuit without antenna attached In the Etherwave Standard Plus Pro the higher one is used and intended link Report Post Posted 3 22 2012 2 44 16 PM 5 RS Theremin From 60 mi N of San Diego CA Joined 2 15 2005 threads posts dewster said This makes me wonder if RS Theremin s designs are jumping to this second higher resonance I see the second resonance on the bench with my AFE but I don t see the peak voltages associated with it Want a real simulator I will send you a 900 kHz oscillator board already constructed and pre tuned to a gold coil antenna along with an old RS detector pre amp board I have old stuff left over from research You just need to furnish a good earth ground and small camera tripod 1 4 20 to suspend the base board with pre mounted antenna Remember your first construction project when life was simple Think Legos I have the pieces Lev Sergeyevich had a favorite toy department Detskii Mir in Moscow where he found his electronic parts in his later years He often visited when the sun was shining We never know what is possible with the human spirit Lord forbid it might just be something fun There is the possibility the Lev Antenna which is a gift is not for everyone Christopher link Report Post Posted 3 23 2012 3 30 47 AM 6 dewster From Northern NJ USA Joined 2 17 2012 threads posts Thierry This simulation is a good starting point Unfortunately the parallel winding capacitance of the linearization coil is not yet taken into account although it can have a very strong impact on the tone spacing close to the antenna I worked on it some more I added a second linearization coil and all three inductors now have parasitic capacitance and DCR http www mediafire com axhjc9fwk4l10dt Also two selectable tank excitation modes It s nice to have a more accurate simulator but it is a bit more cumbersome to use with all the parameters I hope it isn t too off putting RS Theremin the EWS has a strong EM field reading of the 278 kHz the oscillator freq detectable with accuracy to just over two feet away from the Ant If I do the same experiment with the Lev Antenna you can only get a freq reading if the plastic part of the probe in your hand is pressed against the coiled antenna The RS Theremin Lev Antenna response is still out to 4 and linear What are the LC values you

    have a waiting list of people who are asking how to get a Pro some folks want a backup instrument eBay is another choice but with this kind of rare and valuable instrument I d be VERY careful about selling it The last option is a private auction house They re going to charge a large commission though If you do decide to give it to a great home for 50 please let me know first link Report Post Posted 3 21 2012 1 28 11 AM 3 SewerPipe From Flying with the Phoenix Joined 3 9 2011 threads posts I ll give 50 00 and pay the shipping just kidding as Jason said your Theremin is worth far more than that Can t blame a guy for trying thou Have a Blessed day Dana link Report Post Posted 3 21 2012 7 17 22 AM 4 Thierry From Colmar France Joined 12 31 2007 threads posts I have been the man in the middle for several Etherwave Pro transactions in Europe in the last time That means that people asked me to check calibrate and eventually upgrade the instrument during the transaction The sellers got depending of the instrument s condition and if it was already upgraded with the EPVM1345 module between 2250 recently for an instrument which had some scratches and needed the pitch rod to be replaced and following calibration and 2700 for an instrument in mint condition but not yet upgraded about one year ago The buyers paid these amounts plus shipping costs plus a fee for my check repair calibration upgrade efforts The total never exceeded 3000 link Report Post Posted 3 21 2012 8 23 24 PM 5 matrix1 Joined 3 20 2012 threads posts Hi therry are you living in Europe may be in France can you inform me about the upgrade and the EPVM1345 module Well I have to confirm that I am really ready to lose my EPro and my Perspehone as well and lot of my analog synths bought during 30 years for an good sounding Grotrian Steingraeber acoustic piano and eventually martenot ondes and depend of money feed back Vibraphone but I can confirm that mind is in really excellent cosmetic and electronic conditions If people here would be interesting on my Theremin I would prefer to sell it here than Ebay or even private auctions Thx every people for your light sorry for my poor English language and thx for your very low price private joke proposition guys 50 UDS could be a good price for my Epro but please don t ask me to include shipping costs thx link Report Post Posted 3 22 2012 6 36 58 AM 6 Thierry From Colmar France Joined 12 31 2007 threads posts matrix1 Oui j habite dans le nord est à Colmar Si vous voulez prendre contact n hésitez pas à m envoyer un mail à theremin arobase tfrenkel point com N oubliez pas de me communiquer votre numéro

  • Theremin World - Topic: Idea for Theremin Staccato Pedal
    lab next time im allowed into my house and see if I can find one or the circuit for one The above could have problems operating with a plate on the floor What makes capacitive volume circuits complex is the requirement for range and linearity The pedal wont need much range I would think Have just seen specification of 2cm so this is mostly redundant I guess 6 for maximum volume The law might be a problem It would be much easier if foot down was maximum volume I think foot physiology probably makes for more extreme movement with the foot close to the floor than when its raised which is really the opposite of what is needed if minimum volume is near the floor To get a linear response with minimum volume at floor level one probably needs to compensate both for the capacitance effect increasing inverse square as the foot gets closer making the change more rapid and for the foots mechanical inclination to being more rapid as it gets to floor level what one needs if floor soft is change to be slowest as the foot is lowest Probably requiring quite a lot of curve bending the 2cm specified in the diagram removes any issues about foot control but could cause difficulty in other areas It might be difficult to keep the field so small may need more like 4 or 5 cm If floor loudest then things might be almost right without any compensation It could still be snappy but would also allow for control of dynamics I think that an uncompensated floor soft scheme would almost be an on off control with extremely little control over dynamics Fred PS I would be happy to build this for you Even happier if it was interesting enough to put into production and some competent seller was to market it or better still take the whole process of purchasing manufacture marketing off my hands and give me a commission Just been looking at the ZVEX pedals 200 up Information on the Wah pedal How it works The probe circuit generates a small one or two inches high bubble of RF energy at about a million cycles per second above the copper plate Lol someone else who thinks bubbles Ok 1MHz 2 sensing Thats REAL simple As your foot or hand or any wet or metallic object for that matter approaches the copper plate the RF field is disturbed and the circuit reacts by increasing the brightness of an LED which drives a photoresistive cell and controls the Z Vex wah circuit The wah circuit is actually the Seek Wah sound circuit without the sequencer control It s also the same wah circuit as the one in The Drip guitar that I make The only difference is the boost circuit in this Wah Probe model Adjustments The simplest one of these is the volume level of the drive knob just set it so that when you kick on the wah it s doing its stuff at the right intensity It goes from slightly lower than the normal guitar volume to completely bonkers when turned up all the way I personally don t think it s necessary to turn it up all the way in fact it seems to pretty much obliterate the wah sound but to each his own Abuse those transistors please The next adjustment is the RF field screwdriver adjustment on the bottom of the pedal If you turn it in the direction of the arrow usually to the left for that one it will make the probe circuit more sensitive and set the bottom setting of the wah higher and higher It s best to hold the pedal completely upside down so that the cords are dangling away from the antenna with your hand and arm completely away from the antenna and strum your guitar s open strings you probably have to have it on a stand or strapped on thru the Wah Probe Gently adjust the RF pot with a tiny screwdriver in the direction of the arrow until you hear the wah get to the level you d like it to be when you are not putting your foot near it There s a region where the sound of the guitar is kind of muffled and the wah kicks in after your foot gets near the pedal which is how i ship the unit If you like the wah to be partway cocked into the lower wah region just park the adjustment right where you like it As you get closer to the unit it will wah higher The other adjustment isn t too intense it s the LED current control You can usually leave this one at exactly halfway That s how I usually ship the unit If you think the wah is too bright when your foot is all the way on it just turn this control to the left to make it a little duller at the top end I ship it so that with a pair of heavy Doc Martins the rock and roll shoe of choice for many musicians my foot will make it go from muffled to very bright And it all looks really crude and low tech So question What are is the maximum tolerable sensing range assuming 2cm is the minimum No other questions really The big one is about floor soft or floor loud and how important this is But with 5cm span either is possible floor loud would be easiest technically and be less difficult to tune less subject to drift link Report Post Posted 4 11 2014 7 10 55 AM 3 GordonC From Croxley Green Hertfordshire UK Joined 10 5 2005 threads posts Thank you for your thoughts Fred I should make it clear that I have no intention of rushing into this I would like to garner as much feedback as possible before a prototype is constructed both regarding the technicalities
