Multicomp Pro MP710081

Bench Power Supply Road Test

The Multicomp Pro MP710081 bench power supply is a great power supply for use in electronic project videos because it is totally silent and it packs a lot of functionality into a very small footprint, which allows more room for other apparatus and tighter zoom on the complete project.

The USB to banana plug adapter is described in a separate blog that includes manufacturing files:

  • Ah, now we are talking...

  • I can relate.  I've made videos on YouTube.  I have all these ideas in my head but when I look into my camera I become self conscious and forget what it is I was going to say.  Your video came across as very authentic.  I laughed when you plugged in the power supply and then realized that you trapped yourself.  I also chuckled during the unboxing when you started to casually toss all the packing material onto the floor.  So these human touches combined the information you presented made for a really enjoyable video.

  • Very enjoyable and informative video.  Also assessing the product in terms of how suitable it is for videos was definitely very unique.  Even if you aren't making videos the products compact size is definitely a benefit.  Being nice and quiet is also a plus.  I like how you measured the voltage drop over the USB cable.  When it comes to measuring small resistances I think your technique is more accurate and reliable than using a multimeter.

  • Good advice, nice to know there are other humans out there...Relaxed

  • I've been expected to create more video content at work, so I've read quite a few "How To" blogs.  Some of the guidance really resonates... like "perfect doesn't always deliver".  A little bit of being human makes the content creator more relatable and, therefore, the content is more trustworthy.

    As the content creator, we have a tendency to WAY overthink things - including the things that we wished that we had included.  There's only so much time before the viewer drifts off.  Hit the high points and move on.  Leave them wanting more, not bored or saturated.  As to the transitions and edits... even the polished YouTubers have them.  Don't hold yourself to a Hollywood movie standard.

    Some of my perfectionist tendencies, I can't shake.  I do write a script and use a teleprompter.  I'm probably 95% accurate with reading the script.  It helps me feel like I have flow - but mostly it gives me an opportunity to edit my thought NOT in the midst of recording.  Dave's recommendations are excellent however...

    Great video.
    What makes it great?
    Did it achieve its purpose?
    Did you succeed in teaching the viewer why to use a benchtop power supply?
    Did you successfully demonstrate how to do a few useful things with the benchtop power supply?
    Did you provide compelling arguments for purchasing the Multicomp Pro MP710081 Power Supply?

  • They asked for a different format Relaxed - I am curious to see what the other 2 road testers do.

  • That was one of the strangest power supply review I've ever seen. I mean that in a good way. Upside down Very original.

  • Thanks for taking time to articulate detailed feedback. It will help improve future blogs.

  • Most of the road test video above worked well as a facing the camera format production. I think though it would have benefited from a few close-ups of the PSU when you were talking about specific features, e.g. the three sets of outputs at 02:56, the adjustment controls at 03:20, the display at 08:50, and the USB circuit board at 12:30. Especially for viewers not watching in full HD resolution or watching on smaller displays. 

    The setting up of the PSU at 14:13 would have benefited from being framed from your point of view as the equipment operator, however you talked through what you were doing which helped the viewer understand what was going on even though they couldn't see it. It should be less frustrating for you as you aren't having to adopt unnatural positions to operate equipment. 

    The Sammy Semaphore demo had a slight issue in that the motion of Sammy's arms and the updating of the torso text display tends to distract the viewer from the PSU display. I've watched this part a couple of times and have had to replay it each time to observe what the PSU was actually displaying. An action replay of a close-up of the PSU display may help viewers here who missed it.

    The only other thing I'd perhaps mention are your jump cuts are quite noticeable where you have done retakes.

    Have you got much control of the shutter on your camera? Some cameras have a synchro scan mode that allows you to dial in the shutter speed in small increments to closer match the update of the display readouts to reduce the flicker.

  • That seems to be a successful formula. It will take some work for me to get good at it.
