Testing an XRay tube bought from Aliexpress. this device have a very crude design and spills radiation everywhere. Nevertheless it works as intended! 30cm of concrete floor 4m distance results in 0.5uSv/h dose ration I've received for a total of 40s during my various experiments because there is a big aperture on the floor for the stairs and 50keV XRays bounces on the walls!

Un bel giocattolo... mi ricorda i circuiti che taravo a metà degli anni 80' (12GHz), solo che il substrato era di allumina e la taratura si faceva ugualmente con alcuni pezzetti di allumina, da sovrapporre alle strip ed incollare in sede. Anzichè un'antenna a tromba, vedrei più pratico collocarli nel fuoco di una parabola offset per ricezione satellitare.
Eh si... gli oscillatori DRO sono lo standard de facto per gli oscillatori a bassa potenza e basso costo degli LNB e di questi semplici rivelatori doppler per antifurto. Il substrato è FR4... misurati danno qualsiasi frequenza nel range 10.5-10.7Ghz con potenza misurata fra i 16 ed i 21mW su 50R
Nice website but, please, put references to your site and to the material that you use in the description
Can you show all the set-up? Circuit for the tube and the detector (a fluo screen?)
Ciao, il video mi è piaciuto ma ammetto di essere assolutamente ignorante di elettronica ed ancora di più per elettronica a queste frequenze. Mi piacerebbe vedere cosa si può fare con questi moduli. Tu hai parlato di modulare la frequenza per trasmissioni ma quanto possono trasportare lontano? Tra l'altro ho capito bene che questi moduli devono "vedersi" per comunicare?
Si la comunicazione avviene solo quando fra i moduli vi è diretta visibilità ottica quindi, fra due monti sono possibili collegamenti di anche 200km e più!!! I 10Ghz poi non hanno quasi rumore in banda quindi possono essere usati agevolmente per link punto-punto a bassissima potenza. A breve proverò a mostrare come fare un RTX completo basato su questo modulo... attendo l'arrivo di qualche modello dalla Cina. Al momento ho provato a fare dei link con un RTX WFM (1Mhz di deviazione FM) con Gunnplexer e la cosa funziona ma devo ottimizzare la catena di media frequenza
Хороший звук. 👍
Hope not tested in Romania where x-ray tubes are considered military equipment.
what kind of detector is it?
Very +rad creation
Very nice!
Yup. I've an old but reliable XRay ion chamber made for radioprotection. No scattering cause the tube is very directional and the "irradiation" chamber walls are fully covered by almost pure lead sheet in 2.5mm thickness that absorb everything.
hello my ruclips.net/video/ld4oCdEuafk/видео.html
you should consider some type of lead enclosure
now you need xray film. try xraying random stuff like flowers, watermelons, pumpkins and see how they come out. xray flowers come out pretty cool
So how many of these would it take to build a reasonably effective death ray?
awesome! whats the name/model of a tube?
Aliexpress marks it as "8ma"
The green dots appearing all over the camera image weren't reassuring
Hehehhe that's completly normal phenomenon
0.5uSv/h? Not great; not terrible
did he died
Huh? Did you mean did he die?
@@CajunReaper95 died is correct here
No I cannot die, I'm a cyborg 😂
Nice video, but I wouldn't trust that cheap geiger to assess the dose rate and danger :S
It's a geiger counter... it cannot be trust by its own nature, its error anyway could be no more than ±30% at least. Even with 100% error 0.4uSv/h is really a don't worry dose rate. Usually I prefer to use pancake geiger in beta flux mode to have an idea about what's happening and estimate the flux/danger. Distance, concrete and lead sheet helps to reduce risk at minimum. Sadly properly calibrated ion chamber or scintillator for low energy xray are hard to find... I rely on a Mirion personal dosimeter that is not worth showing cause it almost doesn't even detect <1uSv/h ±50keV xrays. I will make a video of it in front of the beam maybe
@@lucianioanpapadopol9401 Ohh, I see :) I'd definitely watch more videos on this topic!
There’s a reason people who work with nuclear materials use dosimeter badges as the gold standard for radiation dosage. Geiger counters just tell you if you need to leave ASAP. I’d never trust one for long term doses. Either way, X-ray tubes like that aren’t very dangerous unless you’re using them day in and day out. Early X-ray technicians got terrible problems from cumulative doses, but patients at worst would get a sunburn.
Youre still getting dosed with scattered x-rays. Do you have a counter that's sensitive to lower energy photons perchance?
I want to make a geiger counter. I wanna know which tube is better sts6 or sbm20 i can get the sts6 for 2/3 the price of sbm20.
Ottima recensione. Che film hai usato per l'ultima foto? Grazie
Si può fare anche senza cavatappi. La pellicola esce comunque senza problemi.
Buen chip
Скорее всего для CB он переделан. Убрано всё лишнее, ну и напряжение побольше на анод подкинул. Для 4 ватт в катод, вполне для CB сгодится.
What screen is that ?
Grazie per il bellissimo video. Ho sviluppato il mio rullino, ma ho notato che la Hp5+ ha parecchia grana, che pellicola iso 400 mi consigli che non abbia questa grana cosí evidente? Grazie 😊
УМ-3 это. Армейский усилитель для Р-105- Р-109, там 6п15п в доайвере стоит.Только почему-то он у него разобранный .Работает от 20 до 50 Мгц. Был такой у меня в 90-е годы.
for the past 4 months i’ve been forcing the lens to close without pressing the button lmaooo:( it works still so i’ll be careful from now on

I am getting ready to fire my ²⁴¹Am at my CsI(tl) in a vacuumed pathway. I want to investigate the energy/air density ratio for use as a cheap and handy vacuum gauge. We all know those fat, lazy alphas don't travel far in air. How well and how far in a high vacuum? Can I detect the change in ballistic trajectory over several feet? Is there much, if any, influence from a magnetic field upon the neutral helium nuclei path? I am too clumsy with ²⁴¹Am. I had 15 replaced smoke detectors donated by maintenance man. Now I only have 5 pellets left.
