Would this be the same for the FT8900R

I honestly don't know but some viewers indicated that its the same for tue 8900

Great video. I'm interested in replicating your power supply for use in an electrospinning device that requires between 10 - 30 kV. However, most commercial power supplies (such as the SKE EF020) limit current to around < 1 mA. Is it possible to reduce the current in your design whilst maintaining high voltage?

@BalticLab 8 күн бұрын

You can limit the current to 1 mA by adding a current limiting resistor in series. Just make sure its appropriately rated for the voltage and the dissipated power.

I am a student studying flicker noise, is the y-factor method valid for measuring flicker noise?

@BalticLab Ай бұрын

Hi! That's probably not a good method for measuring flicker noise as thermal noise us the reference, yet all test equipment will bring it's own flicker noise issues with it.

If you have a FLIR camera, you can try to see the beam itself. Perhaps some smoke is needed too.

Is this under black light or is this emitting light with hydrogen peroxide?? So pretty! I mixed rhodamine b and fleuroscine with rubbing alcohol but never hydrogen peroxide..

@BalticLab Ай бұрын

It's an aqueous solution with NaOH and hydrogen peroxide. Basically the standard luminol recipe except with multiple, unstirred fluorescent dyes at once.

Those bubbles slow down the etching a lot. If an aquarium air pump is added to mix the etchant the process takes minutes. I've built a flat tank from acrylic for this purpose, it reduces the amount of liquid needed and placed the outlet of the air compressor at the bottom. The liquid gets stirred extremely well.

@murad19882003 Ай бұрын

Nice setup, these Chinese laser tubes are cheap but dangerous due to their highvoltage wiring and safetyless HV power supply. 30kV with no proper HV shielded cable and a return path to the power supply housing is a deadly combination. Water ports are fragile. Life time is abit over 1 year then to the trash. Beam has usually side lobes and not pure gaussian, so this thing good for average quality production in job shops.

@murad19882003 Ай бұрын

An RF supplied CO2 laser is much safer and compact and servicible but more pricey.

Very interesting video! Not sure if this would be something you are interested in or have the time for but I would really appreciate much simpler and in detail versions of these videos. An "explain me like I'm five" version so to speak. Questions to answer could be: What actually is a LNB? What does it do? How does a horn antenna/waveguide work? How does the amplification work? And how does the signal look like that is being amplified? What does K-Band mean? There are a lot of channels explaining the basics of electronics but I think application-oriented explanations would make these theoretical lessons much more interesting. I know your channel is probably for viewers with more knowledge about electronics. So it's just a suggestion :)

@BalticLab Ай бұрын

Actually a great idea. With the depth and complexity of RF I will have to think about how to best do that, whether it's gonna be a 1 hour video or 10 segmented videos. Maybe a combination, a teardown vid followed by derrivatives of interesting features in the design.

Are the 38khz sidebands AM modulated? (prior to FM modulation of the whole signal for transmission) If so, that's kind of funny that FM stereo contains an AM component.

@BalticLab Ай бұрын

It's double sideband modulation for the 38 kHz subcarrier. This modulation type stacking actually happens a lot. FM subcarrier modulated onto an AM signal is used in aviation VOR stations for instance.

@ChipGuy 2 ай бұрын

Interesting IC. It replaces the dielectric oscillator, mixer, amplifier, voltage comparator and 22kHz detector. 20 years ago this would all be discrete components.

fyi, a CO2 laser is around 10 micron (mid-ir) wavelength and cannot be frequency-doubled to produce green light. to achieve this effect, your source laser must be around 1 micron in wavelength.

@BalticLab 3 ай бұрын

4 kW? That would pose extreme challenges if it's supposed to be a PCB design. Even neglecting any components on the PCB, just the dielectric strength of the PCB itself would have be extremely large.

Nice Video of Wilkinson theory! If I am making a combiner for 88-108MHz, how do I make the combiner wide enough to pass the Full 88-108 RF spectrum?

@BalticLab 3 ай бұрын

Large bandwidths and Wilkinsons are somewhat challenging. For that you'd have to employ an intermediate impedance and basically do a multi-stage Wilkinson with stepped impedances.
