I emailed these guys and they stated that they are working on a true TS-200 that use USB PD instead of Quick Charge. With that we may get far higher power going through usb c.

[@franciscomendozabalderas18]

The TS80 was called TS200 in the prototype stage.

[@Thorhian]

Francisco Mendoza Balderas yes, I know. I emailed them last month. The TS-80 uses quick charge, not USB PD.

[@IanTester]

Sweet.

[@christianhunt7329]

[@Thorhian]

Christian Hunt They refused to give an ETA for it, and stated they needed more time to work on it. I would be surprised if it came out this year, especially after working on this power supply.

[@Patrik2166]

[@sasodoma]

Too bad that they again didn't implement USB-PD. Though admittedly the QC 3.0 is a lot easier to do, USB-PD can do up to 100W, which would be really useful with this as well as their TS-80 soldering iron.

[@MrSopuli3]

The ts80 is still great in my opinion, mine has been working great after i flashed a new firmware to it

[@ionstorm66]

I'd rather have the DC barrel jack than USB-PD.

[@sasodoma]

@@ionstorm66 The power supply has the barrel jack as well and for the soldering iron you have the TS-100 if you prefer the barrel jack.

[@GnuReligion]

Wow, this does look very slick. So, you over-boost, capacitor smooth, smooth with ferrites, then use an RC filter with a series pass transistor? Did not see a monster diode, so it must be fully synchronous. Looks like it has some huge multi-layer ceramics. They make 107s now. Lots of brainpower went into this design! Seems like the feedback loop time would suffer -- but I guess the whole thing is so high frequency that it does not. Must be running at >1MHz. Glad you took the time to "screwdive" right into it. Am putting that word into my collection of favorites.

[@timthompson468]

Very interesting gear. Sometimes efficiency is relative. I was playing with an old Philbrick +/-300V tube based linear power supply, and they touted efficiency in their data sheet. There was no switching pre-regulator in those days. I don’t recall how many watts the filaments consumed.

[@Nono-hk3is]

Your quadrapedal drone is awesome, but I'm not in love with the deployment mechanism.

[@MostlyPennyCat]

Some sort of STOVL system? With a ramp? And a little pop out wing pack on the silly little thing. Oooh, and a remote sensor pack, width radar and flir.

[@Arcgateway]

I would recommend trebuchet for maximum deployment efficiency

[@XtianApi]

I have their electronic load. It's very nice. Battery powered, has sense wires and dissapates a ton of power and actively cools it. You legitimately freaked me out and startled the hell out of me when I saw that tentacle come out

[@omarsharif4181]

Excellent video with honest intelligent reasoning and analysis. Keep up the great work!

[@thetechgenie7374]

You can set the input limit current. Just long press the menu button on the power supply and it the first option and set current lower, so won't draw 4 amp on a power bank.

[@BrendaEM]

That looks a lot like a turbomolecular pump, for getting rid of those last pesky air molecules. You spray, set traps, and once you have air molecules, and what is worse, too few for Brownian motion, you got to fling them out one by one.

[@shazam6274]

Hints to remove the noise in switching power supplies. There are several FETs for the switches, which can have the noise significantly reduced by adding an "asymmetrical, bi-directional RC filter" (resistor in parallel with another (resistor & series diode) ) in series with the gate. This alone can reduce the noise by an order of magnitude. To get to uV noise levels, measure the noise frequencies with a spectrum analyzer at various loads. Amazingly, most will be in the 50 to 200 MHz range. Use a de-tuned parallel resonant inductor filter (~ 0.5 uH || 5 pF || 4.7 kOhm for starting values)) in series with the output, ~ -40 dB in the FM band. Calculate and simulate all you want, but the values will have to be optimized empirically. Fun Facts: 1) Even though the switching frequency of the power supply is dozens to hundreds of kHz, it is the rise and fall of the switches (and rectifier diodes) which generate the noise in the above (and higher) bands. 2) Rectifier diodes, when starting to conduct, generate a high current pulses in these bands regardless of switching frequency. 3) Because of the VHF (and higher) frequencies involved, you can add all the capacitors and inductors on the output and still have a lot of noise.

[@jan_wh1tey]

I've had a minor obsession with trying to detect very-low-frequency sound (infrasound and below) for a couple of years now. Unfortunately, it's been hampered by my thoroughly corroded brain and my spotty-at-best knowledge of electronics. But your laser experiment gave me an idea: picking up sound with some sort of absolute position indicator. A high-resolution linear encoder, perhaps, or a rotary encoder attached to the vibrating object with a piece of steel wire on a pulley. Now I just have to learn to read resistor color bands, remember the names of the terminals on transistors, and, most importantly, get off my lazy arse and actually solder something once in a while. But when I get there, infrasound.
