Thanks Chris I was just looking at these on BG this morning actually. Great timing :)

What you said about soldering in reference to Murphy's law; it's absolutely true and happens with me too often. Sometimes I solder pads or wires very neatly and evenly which also so shiny that I could see my face on it. The moment I start feeling great about it, I'd find that I did something really wrong; may be forgot to insert a sleeve, a washer, nut, or a cap. Some might say it's my negligence not doing it correctly at first. But I always try to give extra care to do the soldering and wiring perfect except this happens often.

Exactly !!! LOL !!

Besides sometimes forgetting something that should have been put over the wire before soldering I also find that while I was focused on soldering the heat shrink has slid close to the iron and shrunk. So I have to desolder, get the heat shrink off and do it again. Almost always the solder joint the first time looked absolutely great.

wow. I've been holding off getting one of those supplies because of no case. looks great! More quiet fans are pretty cheap if the noise bothers you. fan noise doesn't bother me. Some noise seems right when I'm in the lab.

I know right? It's funny that it was seeing the case that made me buy it :)

Old video but just wanted to mention that this type of casing is used for many types of electronics and can be open from a side like a book, and closed too. No need to slide the halves into the slots.

wow! I did watch your 1st vid on the 5015 and went out & bought one - loved it but, as you know, it was unwieldy w/o any case. My new one just arrived today & searching for an assembly for it, ran across your vid on it. I don't know how i missed the vid when you 1st put it out 'cause I'm a big fan and have just finished going through your quad for beginners series (also great). anyway, I'll be using this as I put this puppy together later on this week. thanks for all your videos. are you still using the CNC with the water cooling unit? thanks again, Russ from Coral Springs, Florida, USA

Thanks for this. I'm going to get one of those cases

Now I watched this video ...thanks for the update. Again...have you used these to charge a Lithium battery?

I'm considering buying one, I'm wondering could you test a homemade electromagnet with it? Like just wind wire arround a nail and hook it up directly to the power supply and set the power to like maybe 6 volts, I want to know if it works because my previous buck converter type things never worked with a electromagnet

Thanks for sharing this, a bit late to the pardy, per usual, but I found it useful and enjoyable... 👍🏻 😉 🐍

If your having trouble with solder joints not looking good, especially if you are reflowing existing solder, try adding a bit of rosin flux before reflowing. The flux residue is messy but it can be cleaned off with alcohol or acetone.

Sorry was getting excited, thought this was a replacement 100 volt dc power supply for your cnc router motor. Will have to go back and check your videos on that because I never got rid of the same issue you had with missing steps when using the same spindle and power supply you had. Great video anyway, thanks

Missing steps was not the problem I had. Mine was completely losing contact between the arduino and the laptop. Missed steps could be because your motors are not powerful enough, or the frame is not rigid enough, or you're trying to move too fast. Perhaps you could give bluetooth or some other wireless method a try.

whilst correct, you're better off just adding a thermostat so it's silent unless it's over x degrees. I screwed my thermostat to the same TO220 existing screw.

nice assembly follow along. i was thinking could use 14 even 16 gauge wire for how short the distance is. this would help with assembly not dealing with stiff wires. i guess it depends on how many amps for how long.

I have just started fabricating a case for mine, but bigger so as to hold the 600w SMPS to drive it, I might get the pre made case for the 5A one I haven't yet used, after seeing your video. Looks good, I can fit the 180w 36v board in the back. The auto start enable is very good if you want to use it for integrated applications where it just needs to work all the time, in a power failure it will re start by itself. Anyway, another good video, cheers.

Just like it used to say on my school reports: "must pay more attention"! After I watched this video I thought "I like the look of that, I wonder what it costs", so I watched it again, and at 1:30 there was a pic of the complete unit showing the price of US$19.99. If I had paid attention, I would have worked out that price is for the case only! It seemed too good to be true... and of course it was! Still, I do like the look of it. :o) Apologies to anyone I confused.

I wanted a case that was large enough to put a transformer and bridge rectifier in it so it can be plugged into a wall socket.

I have a similar model however mine can be controlled by computer via Bluetooth and USB. When you order it the usb and Bluetooth are options available for a little more money. The software is a bit odd but a free download. Also it’s possible to put in a switch to turn the back fan off. It’s worth pointing out that if you want to power this from the mains you need a separate DC power supply. Banggood sell these.

Sadly, the case kit is no longer available

Are those new units have some additional protection to not be killed easily? Otherwise they are not worth money.

I like the idea of having the unit boot up but not yet turned on to provide power... something of a safety issue to force me to turn on the power with that power button once I have double checked the values that are about to be introduced into whatever this unit is hooked up to. If this unit were last set on some higher values than the circuit can deal with, and power was applied the instant the unit is given connection to power, then the hooked up circuit might get fried. Thinking of those times when things are turned off at night, new circuits are plugged in "ready to go" except that the power supply unit has not been set to the new circuit values... switch on... SMOKE!

I build my own, using modules in some of them, and like to control the voltage and current with pots then get on with what I wanted to do. I like many of your other videos but not this one eg "Which memory, will it save, do I switch off or on, does it delete all settings"?

? That would depend on what power output and input voltage you have... from the specs on the product page: Input voltage range: 6.00-60.00V Output power range: 0-750W If the maximum output power is 750W then the maximum input power is also about 750W. So the maximum input current will be 750 divided by the input voltage.

iforce2d it wasn't clear that you need to push the bolts into the fan holes first.

You really should thread the wires through the holes and secure them mechanically by bending them around the posts. Soldering is not a secure connection by itself. Whenever the solder joint would break the wire should stay in place.

Isn't it a regulator. It doesn't come with a transformer.

Everybody complains about the fan noise, I don't get it. I think it fine.

It is a nice case. But since it has no room for a transformer, a rectifier and some filter caps, you can not use it to build an AC powered unit.

I ordered from Banggood $20 for the case

Wow, that case looks really nice! I did not expect this level of fit and finishing. For what is included it is still reasonably cheap. At the end: you switched off the PSU without leaving the setting screen the first time. I think you said yourself you have to be careful what buttons to press for the settings to be saved. If the fan annoys you, there are several things you can do: First get a new fan ;) . Maybe the included one is just crappy and loud (although most small ones are). Better way would be to add temperature control, so it only runs when needed (you could also hook up the second fan to that). There are simple circuits with just an opamp or NE555, a transistor, NTC and a few resistors for on/off control with hysteresis. Or you could go for temperature speed control. Most circuits you find that do voltage controlled PWM (at 5V) should be useable with slight adaptation. E.g. 3 opamps, (two to create a triangle wave and a third one to compare to a voltage derived from the NTC) is an easy one. A quad rail-to-rail (because of the low voltage) opamp (like an LMV324, you could say that's the rail-to-rail version of the LM324), the NTC, a switching transistor and your usual assortment of small parts like resistors and capacitors is all you need.
