Ramsnovice Max Klare incorporates uphill climb in direction of stand out within crowded TE house (by SilasEckley)

The Los Angeles Rams include put in seriously inside the limited conclusion level within just the ultimate several seasons. Among Colby Parkinson, Tyler Higbee, secondyear playmaker Terrance Ferguson and Davis Allen, starter Max Klare is following inside of line in the direction of generate sufficient taking part in period inside the RamsTEheavy is L.A. moment directly restricted close preferred inside the NFL draft, moving No. 61 in general in just April. This arrives once Ferguson was taken 46th all round inside of past year is shifting in direction of comprise his operate lower out for him if he targets in direction of stand out within this wealthy grouping. Hel unquestionably consist of an uphill climb. Regretably, his functional expertise as a obtaining TE not in the direction of point out surviving the Purdue Boilermakers could possibly maybe produce him stand out in just the towards terrible Boilermakers in direction of greener pasturesKlare attended St. Xavier within just Cincinnati, Ohio, and devoted towards the Purdue Boilermakers out of superior faculty as a threestar recruit. He selected the Boilermakers around universities together with Duke, Japanese Michigan, Ga Tech and the regional Cincinnati the duration of his to start with 2 many years at Purdue, absolutely nothing of take note transpired for the more youthful restricted close. He performed within precisely 2 game titles in the course of his freshman marketing campaign inside of 2022. Then, the right after 12 months, he was upon his path in direction of perhaps breaking out in advance of ache a seasonending destruction within just a 4419 gain higher than of the harm, Klare was a respected concentrate in just shortyardage circumstances. Purdue quarterback Hudson Card sung his praises in the direction of Sam King of the Lafayette MagazineCourier, a indication of nearly anything one of a kind towards occur inside of 12 months 3:e 1 of the most straightforward limited finishes that Ie been near. He a fantastic participant. He can block and he on top of that operates some of the perfect routes that Ie been close to. He results in my everyday living basic and he relocating in direction of do some unique experienced the ideal period of his collegiate profession inside of 2024, foremost the staff with 51 receptions for 685 yards and 4 touchdowns, which was the sixthhighest having yardage all round through a TE in just software package background. In accordance in the direction of Purdue Sports activities https://www.dallasteamshop.com/collections/shemar-james-jersey, he completed 8th in just the FBS in just having yards through a restricted stop and was the 9th substitute Huge 10 TE given that 2000 toward history at minimum 680 obtaining returned against destruction with a vengeance in opposition to FCS Indiana Country within just the year opener with a fivecatch, 71backyard manufacturing. Afterwards inside of the year, Klare furthermore recorded a careerhigh 133 yards towards the Preventing Illini.

Even though in just Columbus, Klare labored toward increase his avoiding. Currently being with a contending software package appeared in the direction of carry out his easiest, as he took effortless consideration of his Buckeyes coasted in the course of the every month period undefeated ahead of backtoback losses towards Indiana in just the Large 10 Championship and Miami inside of the University Soccer Playoff. Both equally of people groups confronted off within the nationwide championship, with the Hoosiers coming out upon was nevertheless a profitable period for Klare, even if he overlooked out upon the championship glory. He finished his lone calendar year at Ohio Nation participating in all 14 online games, which include 11 begins, completing with 43 receptions for 448 yards and 2 touchdowns. Even with the insignificant dip within just generation when compared towards his previous year at Purdue, he gained firstteam allBig 10 top of that, he experienced one particular yr of eligibility staying, nonetheless elected towards input the 2026 NFL draft.

That on your own is a in addition and a minus for the incoming the as well as facet, Klare was drafted towards the ideal workers, just one that works by using several restricted finishes at any offered season. Provided L.A. determination toward the level, a receivingfirst TE these as Klare will possibly perspective the sector further more normally than not. As for the minuses, for a single, the Rams picked out Ferguson within just the moment spherical of the 2025 NFL draft, which will supply him precedence upon the market along with veterans which include Parkinson and performed within just 14 video games past period, nevertheless wasn upon the industry as considerably as you consider.

Setup for EV plus — amps (by DreadVox)

A small powered monitor, keyboard amp or acoustic instruments amp are good for home practice and small venues. For home practice you also might consider a headphones amp. Guitar amps are less suited because of the high output level of the Etherwave theremin.

Some suggestions: Behringer KXD12 or KXD15 Ultratone, Vox VX50KB (very lightweight), Roland CM-30 Cube Monitor, Roland KC-80, Behringer Eurolive B105D (small and light weight, can be mounted on a microphone stand, has built-in MP3 player and Bluetooth audio streaming for backing tracks), Boss Acoustic Singer Live LT, Hughes & Kettner ERA C.

It depends on the power supply that is with it how the theremin needs to be grounded, the USA model gives grounding through the power supply, while in Europe and I suppose other locations as well, the power supply doesn't provide grounding, so it expects grounding from the amplifier (or otherwise).
Sometimes one can get away with just using a long cable between theremin and amp draped on de floor to provide enough earth grounding, when there is not too much electromagnetic interference around.

Keyboard amps are pretty good for Theremin. I use to split signal taking one channel into keyboard amp the other into bass amp. Very full sound.

Setup for EV plus — amps (by guillaume)

Welcome to the madhouse 🙂.

If you're only playing at home and small venue, you can get away with a smaller speaker (I've tried and would recommend spark Mini and Sony xb21 or 31). I also have a monitor (Adam t5v) which is great and suitable for large venue (eg. Church size).

It's a monophonic instrument, I don't think there's any benefit to having a pair of speakers.

Feel free to update your TW profile to include your location, there could be other players around you that you're not aware of!

Setup for EV plus — amps (by miss hemulen)

Hi there,
I’m new for theremin and currently building my setup. I’m professional musician and completely clueless when it comes to STEM… be patient please 😅 I’m doing my best!
I got Etherwave Plus (serial number 9000) and mic stand. I’ve just ordered also ESPE01 mod which friend of mine will install for me (engineer).
The instrument needs calibration which I’m going to do but currently I’m struggling with amplification. I think I’ll go for monitor but not sure which one, and should I get one or a pair? I have opportunity to buy pair of Yamaha hs5 monitors in very good condition and price. Do you think they are suitable? I’m afraid they’ll be too loud for small venue (I’ll be practicing at home which is really tiny)…
I feel so lost in all this technic stuff around theremin, really hope you’ll help me!

LCD Dimmer

Revisiting the LCD backlight dimming circuit. The old one was pretty simple, just slightly filtered PWM, with the frequency placed at the highest hum filter notch (200Hz / 240Hz). This caused interference for one kit builder, so more filtering seemed to be in order.

Above: improved LCD backlight dimmer circuit.

The candidate began as a second order low pass filter based on the single transistor Sallen-Key topology - which can be formed by disconnecting C1 from ground and connecting it to the emitter of Q2. This turned out to be a bit noisier than a simple 2 RC filter, so I went with that. I added input buffer transistor Q1 so the impedance could be increased, and C1 & C2 were then reduced to conveniently smaller values. The buffer also raises the turn on voltage to roughly 1.4V, which is close to the center of the PWM signal driving the input, so we use a PWM duty cycle of 50% for off, and 100% for full on. Very little power is dissipated by Q2 or R6, so these can be non-power types such as 2N3904 and 0805 (I have yet to encounter a modern transistor that is as versatile as the 2N3904). R4 is to protect Q1 and Q2 when C2 discharges at power off. R5 is to prevent self oscillation. I breadboarded the circuit and drove the input via a function generator and it behaved just like the sim.

"Though I have to say... 31 years is a pretty good run!" - Jason

Indeed, internet years are like dog years! Thank you Jason for this wonderful resource. I spent days looking for CSS specific working code for the photo and video galeries on the D-Lev web page, and an LLM spit it out in like a minute. Currently discussing Theremin physics and reverb design with Claude and ChatGPT, even the free versions are pretty informed and smart.

Password reset should be working again (by jason)

Hey folks. I've been locked out of my own site here for about 8 months and finally made time to get that sorted out. Along the way, I fixed the "forgot password" feature. So if you've been locked out too, I apologize. Hopefully you can rejoin now.

The site is still limping along, but it's running out of space which will cost another $60/year for an upgrade. Please keep clicking those ads and shopping through our affiliate links to help keep us afloat.

I'm still building the site on an old 2014 Macbook Pro running a copy of Windows 8 in Bootcamp. It's built using dev tools from 2015. I'm honestly shocked it's all stayed working this long. Now that AI is a thing, I'll experiment with getting Claude or Codex to help me modernize the platform. No promises, but it's honestly the best chance we have of porting this to a more modern platform to continue running.

Though I have to say... 31 years is a pretty good run!

Early electronic music before 1945 Substack site with extensive theremin history (by JPascal)

Great to having you here in the forum. Your articles shed light on the significance of Lev Termen’s early contacts and visits in Germany. Abram F. Joffe, the director of the institute in St. Petersburg, had studied under Röntgen in Munich, and G. J. Goldberg was Lev Termen’s technical and business partner through his father’s company, Goldberg & Sons: In the 1920s, the Berlin-based company served as the German licensee and business partner for Termen’s high-frequency sensor technology and the Termenvox devices.

I am looking forward to more of your excellent investigations.

The newspapers of that time carried a statement by Lev Termen, who had held out the prospect of producing instruments licensed to Goldberg in Germany. Well, things turned out differently. However, demonstration units for the Trio ensembles were produced in Germany, and I would be very interested to learn the current whereabouts of these units or their technical details. In the images featuring Goldberg, the two devices with different designs and geometries can be seen.

Encoder Autopsy

Got a wild hare (hair?) to take apart a couple of encoders to see what makes them tick. Jumping right in:

Above: Inexpensive generic PEC11 encoder bought off eBay, which is full height. Note the triple contacts, one on each side to contact the continuous inner section of the toothed conductor, two per side to contact the the toothed section. The contacts appear to be dry. Note also generous milky grease on the detent spring. The internal shaft extension is plastic.

Above: Expensive Bourns PEC11H-4115F-S0020 encoder, which is low profile. It similarly has two contacts for the continuous inner section, but only one per side for the toothed section. The shaft is metal all the way through, and there is only a bit of grease on the detent spring. Notably, there is some form of grease on the conduction side too.

Above: Closer views of the generic encoder (left) and Bourns (right). Note there is much more lube on the detent side of the generic encoder. Note also the small plastic shaft end insert on the Bourns which actuates the pushbutton dome switch.

So, what to make of the above? I think the reason the Bourns has such noisy rotary switch contacts is due to the single contact per side on the toothed section. Dual contacts make continuous conduction more likely. The noise could also be due to the grease or whatever being on the conduction side, though that may be there intentionally to extend the life? The Bourns is supposedly a 100,000 cycle unit, but the batch I bought was so noisy that they're pretty much unusable [LINK]. I wonder if putting some DeoxIT on the contacts might fix the Bourns, or make the generic units last longer?

Max Headroom

Throughout the project, I've been worried about bad DPLL lock, which is possible due to the strong harmonics associated with square wave drive. One way to reduce the number of bad lock scenarios is to reduce the operating range of the DPLL, but this has consequences that I didn't anticipate. Touch the antenna and the LC resonant frequency is instantly and dramatically reduced, but it takes finite time for the drive frequency to catch up, and during that slew other resonant frequencies may be stimulated and locked to. Limiting the upper or lower range doesn't help, and might actually exacerbate things. Starting the DPLL at the nominal frequency is a good first step though.

Anyway, now that these scenarios have hopefully been laid to rest via the new hardware / software watchdog, I though it was time to take a fresh look at the lock range. I decided to remove the lower range limit altogether, and after some testing this appears to be both a simplification of the logic and a good move. The maximum frequency limit being so close to the smaller inductor resonance has bothered me too, someone could attach a very short antenna and be operating even nearer to the limit. So I added some headroom here. The granularity of this adjustment is by octaves, and adding another one doesn't seem to change the operation. So this appears to be a good move as well. In summary: YAY!

Early electronic music before 1945 Substack site with extensive theremin history (by ghost elektron)

Thanks DreadVox and JPascal,

My research on electronic music pre-1945 and Theremin style devices moves beyond Termen's time in Germany, and I'm most interested in the 1928-1934 period. There was a lot of activity involving Thereminists who were trained at the Berlin Theremin laboratory/School of Electrical Music, and who then performed across Europe until 1930 - and elsewhere until the early 1940s 1941. The two most interesting figures were Evgeny Henkin and Martin Taubmann who I have extensively researched and written about on the Song of the Atom Substack publication. Most things written about Taubmann in the past were totally incorrect. I aim to publish more material on these topics soon, though I have written quite a lot already ...

Thanks for your interest in Song of the Atom! I aim to only publish material where I can add new information to the various histories that are already out there.

Building a theremin for a robot voice (by josh craig)

Theremins use oscillators and filters to make their sound. Changing the way you control the theremin turns it into another synthesizer.

Much of the sound of the theremin comes from the way your body directly interacts with the circuit via the electromagnetic field which gives it the organic and hyper expressive quality that seems part-biological and part-mechanical.

I believe this blend is something many people creating a voice for a robot strive for. Ben Burtt achieved this with R2-D2 by vocalizing into different patches on an ARP 2600.

I think your best bet of achieving a theremin-like quality is having a small stylophone on your controller that interacts with an oscillator inside the robot. It won’t sound as organic or unruly as a theremin can, but as far as physical logistics go, it’ll probably be the right design choice.
