Miniware MDP XP Micro Wireless Power Supply

[@KissAnalog]

Awesome video - and amazing product!!! Way to go!!! The ripple is often confused with the noise spikes riding on it. The ripple is actually the charging and discharging waveshape on the caps -ripple;) those spikes are noise and can look worse with test leads and loop area in the measurements. Place a small cap, like a 1 uF at the input to the measurement and it should drop. Also you can use the BW limit on the scope to reduce this noise. Many manufacturers will claim ripple at a max bandwidth. Cheers

Thanks. You interested I'm playing with it, Eddie? Email me if you are [e-mail].

[@1959Berre]

About the word "pressure" instead of "voltage". The official symbol for voltage is not V, but rather U, which is derived from the Latin word "Urgere", meaning"to press, to push". In fact the current is "pushed or pressed" through the load (like a resistor), which makes perfect sense.

[@michaelpadovani9566]

Agree with Kiss Analog comment, i think you're picking up noise on those larger peaks and not ripple. Great review and check of the product overview. For me i would rather have a bigger PS with easier to turn knobs and bigger display. Wouldn't need RF but the graphing and logging feature is cool.

[@mtkoslowski]

_Old school electrical engineering classes introduce voltage as “electric pressure.”_

[@wrex7044]

Would be interesting to know the temperature and ripple after 1 hour @18V 5A.

[@Mainbusfail]

Keep taking your Lasix and take care of yourself friend. I hope you are doing well. Thanks for the video on this little guy, pretty slick PSU.

[@pulesjet]

What are the other O Scope functions ? Surely it has some basic scope modes ?

[@learnelectronics]

Impossible to know. It shipped with no information no instructions and there is nothing online.

[@pulesjet]

@@learnelectronics The Chines Excel at that. It's like they don't know them selves.

[@impmeister1]

First thoughts when I saw the price was; "that's expensive..." Then I remembered that I will travel alot between the two sides of the great pond. It got alot cheaper after that idea, so I will keep this puppy in mind. Thank you for the review.

[@georgechambers3197]

Wireless remote power supply seems a bit of a novelty to me. Sure you can add modules but in the end, you can get one device with everything builtin probably for a lot less money. Neat to look at and probably play with but hardly essential for the workbench. 😁 I don't do Bangood anymore either, the shipping has gotten so slow it's worth the extra to buy from Amazon. Thanks for the video!

[@markgreco1962]

Got mine on amazon I LOVE IT! Love you’re vids Wireless if the table is full and you want to take a rest or a noisy area.

[@bigbadalphawolf9330]

Nice review video of this mini power supply product.

[@markgreco1962]

Do you own on of those USB C type wall chargers has 3 outputs? 5v 9v 12v My Issue is that when i use this wall charger it doesnt power my MDP... are my chargers crap or doesn't the MDP use this protocol.

[@learnelectronics]

I do own one of those, and like you it does not work.

[@markgreco1962]

learnelectronics Thanks for checking

[@Hasitier]

I like that type of little portable supply although I could not imagine a use case where I need to control it wirelessly. And then for 200 bugs with such a ripple it’s a no go. Better waiting for the mycro supply from Dave Jones? I’m sure he can do better.

[@mikeoliver3254]

That is a sweet looking power supply. I wish I could pick up one of those units. Great video Paul .

[@MCsCreations]

That's a beauty! 😮 Some day I'm going to get one to keep in my backpack! Fantastic review, dude! Keep them coming! 😃

[@keithking1985]

That guy who has that electro noobs channel done a video on them. There a really nice little power supply.

[@GeorgeJFW]

Cool device definitely out of my price range but I like the idea of being able to upgrade it with different modules. Great video!

[@mtkoslowski]

Junk From Work : For about $390.00 you can get a great Siglent SPD3303x-e power supply which is a great programmable power supply.

[@flemmingchristiansen2462]

cool device did you check you own power supply for ripple? nice format i hope they keep the format throughout the product line, that would be neat

[@learnelectronics]

My power supply has a maximum 80mV ripple.

[@simeonmihaylov6123]

Linear power supply for like 20-50$ is the way to go. Heavy - yes. Promising a lot of mistakes - definitely. The reason why this thing is so nasty at the output is probably because it's a switching power supply, which is what they do - a lot of noise. But if someone wants an expensive toy to show off - just buy it and enjoy.

[@yurkshirelad]

Apart from portability, I don't see the benefit of this over a much cheaper bench supply. Unless I'm missing something obvious?

[@akai454]

I'm learning Easy EDA and I'm using Your tutorials , THank You :)

[@1959Berre]

This is the thing I would buy when money was not an issue. $200 for a 5 A power supply is a hefty price. So, I will keep on drooling.

[@weerobot]

Never has a Power Supply looked so Sexy....I'm getting one...Marco Reps..KZbin....got less ripple...

[@mtkoslowski]

Thank you for an interesting demonstration and review. I however consider it a novelty item - I’ll stick to my cluster of regular power supplies. 😕

[@whitehoose]

It's certainly a looker. Personal thoughts; I like my DPS5005, not the cleanest supply in the box but good enough for what I do. If I kill it I can just get another, I've already hacked it and added wireless and a different front end for no better reason than I could. I certainly wouldn't dare defile this little beauty or risk killing it without a lot of thought. I don't think I can cope with that sort of responsibility. Looking at my TS80 ... in your hand it's a sensual experience, but as a soldering iron it's a bit of a prima donna. The qc3 "thing" is a bit of a joke. If you don't have just the right type of power source the Iron won't work .... What use is a hammy hammer? A soldering Iron is, or should be the basic pixie wrangler's tool next to a screwdriver (I note their's needs batteries and costs £70!), I use buck and boost to push my luck with dodgy power sources - that adds to the fun and the satisfaction when it works. I can see that there is room for the modular wireless approach - and I can see for some this will be the answer to some difficult setups. I've also struggled with portability issues but I did see mention of qc3 as well - it's not my favourite bit of the ts80 - I hope it's under control now. I don't do the sort of work that warrants this sort of extravagance any longer. Now I get my kick from NOT having all the latest gear and still making lamp come on - lamp goes off.

[@bblod4896]

This is the second time I've seen this supply, guess the manufacturer is going after KZbin electronics video producers to push their product. Interesting, perhaps for a test lab. Thanks for the look Paul. 73s.

[@vegtersbaas]

Suddenly most youtubbers are reviewing this. Though my DPS5005 is still going strong :)

[@davidpyper1688]

Neat device, but I have no use for it. It seems like something one would buy and play with a few times then set it on the shelf and for get it.

[@doughy67]

Good video nice device but way to expensive for a hobbyist.

[@TheGFS]

such a sexy little PSU =) most def getting one of these

[@1959Berre]

Setup sucks. You are picking op noise, do not connect the probe via another lead which acts like an antenna. In induces all kinds or parasitic noise.

[@hobbyelectronics6630]

This exemplifies EVERYTHING wrong with so-called "test Equipment". It is a silly little toy, not user serviceable, pointless features, menus within menus and it needs a power supply. I have an old linear power supply that doesn't need a power supply or require a manual just to figure out how to turn it on. I have the schematic and I can actually buy the parts necessary to repair it, if it ever breaks. I would rather focus on what I am doing , than fight my test equipment. You could buy a bench full of old test equipment for $200. Well "I don't get it" pretty much sums it up.

[@learnelectronics]

Me either. I'm not endorsing it. I'm just showing it.

[@hobbyelectronics6630]

@@learnelectronics Fair enough. I appreciate the reviews. I want to stay informed about new equipment good , bad or indifferent. On another note my KSGER just arrived today. I totally blame you for that indiscretion....joking of course.

[@veryboringname.]

It really depends on your usage. A basic linear PSU can be like an old analog scope - does the job perfectly for lots of people. But some people might find a DSO more useful.

[@beamer.electronics]

Great video thanks. Just a (shot-in-the-dark), thought; your electronic load could be introducing additional noise - try a resistor?

[@coldfinger459sub0]

Interesting. A fun little toy potentially. Definitely not any good for audio or sensitive ic component circuits way too much ripple. 👎🏻 maybe when they release a 2.0 version after they correct some of their problems. As it stands between $60 to $90 and $90 would be pushing it on a good day downhill with a back wind.
