content: I agree. An SSD is by far the best and most noticable upgrade you can make for *any* computer that still uses spinning rust as a main drive, regardless of whatever OS may be installed.Though anything older than Windows 7 might degrade the lifetime of an SSD, since TRIM support is quite important.Mind you, HDDs still have their place. SSDs larger than one or two Terabytes are in my opinion still too expensive to be used as bulk storage, and not everything actually needs the performance of an SSD.

content: Quote from: Ranayna on December 02, 2020, 12:01:43 pmYou can just run a TRIM-free-space utility periodically on 3-6 (NT/2K/XP/Vista) anyway, which is fine for most applications still being done on older OSes, though it is not obviously quite as good as having proper TRIM-on-delete support.It's even not a bad thing to do every once in a while on recent versions if you're doing system maintenance and clean-up anyway. Delete all temporary files, bogus logs, old system restore or downloaded updates, etc. then turn off your pagefile (shouldn't be running a pagefile on a SSD anyway!) and hibernation file, etc. then TRIM.

content: I actually never noticed those three went hole at the minus pole as they’re usually somewhat covered by the wrapping label. And when a battery has leaked you're really not that keen on handling them.I just looked at two several years old completely empty AAA cells - but that has not leaked. The holes are clearly there and looks open from the outside - you can i.e. stick a needle into them. So the went mechanism is not like on electrolytic caps where the top of the casing is designed to rupture - but on batteries there must instead be some kind of seal behind the holes - and it’s when that seal fails or opens prematurely that causes battery incontinence.

It lists videos from both EEVblog channels and is convenient for me: when I'm in the mood for EEVblog I go to EEVblog.No new videos have appeared on the frontpage over the past couple of weeks. I assumed this meant Dave was having a break for a bit, which is more than fair enough.As it turns out however: new videos have been going up, but posts on the main site for them have not been. Is the frontpage extra effort? Is this an accident?

content: give that a paint job with aluminum primer and some nickel paint and it will probably last longer next time. Paint is the best protector here. Dremel flap wheel would clean up the old glue well3m scotch bright pads will clean that up no problem (preferably drill mount) and prep it for painting. Unpainted metal suck. If its something that needs to look like real metal put some mothers magnesium and aluminum polish and car wax (requires maintenance). I have an aluminum table base thats outside in the rain for 1 year under a small table (its not well protected) and it only has minor hazing after 1 year, I have no doubt if I put mag polish and car wax on it before the winter it will look great next year (it was done to a mirror finish).You will be surprised how well mothers mag and aluminum polish can clean up crusty aluminum if you use a buffer of some kind, I got stuff that I thought I would need to sand and completely refinish to near mirror look with it (used proxxon tool bases).I think its worth doing because the backing strip is beefy, that is a high quality heat sink and undoubtably your power system is more advanced and it might be more pleasant to the eyes with 50hz lightingKeep in mind the green kitchen pad is not the best tool here, that might require a brown hardware store pad, and using that mag polish with the pad does still seem to improve removal rate (chemical help), that stuff does some kind of reaction with the aluminum oxides. Worth getting a small buffer for the car anyway, that will pay itself off with wax jobs.. just don't fall too deep into the finishing hole from car finishing guys (OCD like crazy).I can't stand any flickering lights because it reminds me of old yellow city lighting... screw that crapI made something similar for indoor lighting using high quality strips on aluminum flat bars. Not perfect but worth it because I got 100% coverage under the rafters.

content: I bought used shelving, for a lot less than that price, though I did need to use 2 13mm spanners ( and a 13mm socket to make things faster) to assemble it, but it was less than $50 for a similar amount of shelving. I did not have to buy the bolts though, had plenty of them already. Plenty of places have used shelving, and this is a big way to save money on the shelf storage, as you generally are not too worried about appearance of the shelves, just that they are reasonably clean, free from flaking paint and no major rust.Dexion style sheet steel shelving is long out of patent protection, so there are multiple clones of the bolt together system that are, to the most part, nearly drop in replacements for the original Dexion system, though many of the newer ones use M6 bolts and nuts instead of M8, but you can often use the 2 in the same rack row with minimal issues.

content: I have similar shelves. Check if there is wobbling of the sides as a parallelogram. Mine had that issue and was easily fixed using strapping. I suggest go out to Bunnings buy a reel of steel strapping used to reinforce house frames and trusses. Unroll the strap and use a couple of Tek screws to secure it in the rear of the frame, ie: the side against the wall. Works a treat, as triangular sections are very strong and it won't move.https://www.bunnings.com.au/abey-australia-30-x-0-8mm-x-6m-galvanised-punched-strapping_p1090034?gclid=EAIaIQobChMIgaCdq8y_6wIVRw4rCh0MGA_5EAQYASABEgJda_D_BwE&gclsrc=aw.ds

And it's reasonably linear so can be mapped in software reasonably well.In this case with say a 10mohm Rds it's going to be an order of magnitude lower than the sense resistor, and then temp coeff is like a few percent of that over say a 50C range.I deliberately didn't want to go into a tangent at that point.

(and then you can add it or before that obviously send it to someone to proofread if you want to make sure)Apparently you can enable subtitle contributions from the video settings panel but oh dont mind it, that makes my name appear on the credits but i dont really care about credits and besides my youtube account is my real name wich i dont want floating around on the internet.

It was also nice to hear some familiar things from my work with a quantum computer (and to know that what he was talking about was Grover's algorithm (the sort/square root part) and that what puts the qubits into superposition is the Hadamard gate).If anyone's interested, awhile ago I made a tutorial video on how to use IBM's quantum computer (which is free to use) and a tutorial on quantum computing (BTW, in case it needs to be said, neither one is me in the video thumbnail picture - I don't work at IBM, etc. - that's IBM's website that you go to in order to use their quantum computer):

However i want to build a SMPS and also control the current (0-10A) and voltage (0-50V).Can I follow a similar approach? Im thinking on building a SEPIC dc converter and want to control the current and voltage. I then want to display the set values as well as the output values of the current and voltage. So i may use a mirco controller... Any advice on how to approach this?

content: Since I can't resist a short rant about the state of USB drivers on Windows and how that whole process was way harder than it needed to be...It has always been a mess but I wish companies like ST would try alittlebit harder, like not placing their device under 'USB controllers' when it's not a USB controller. Microsoft could also have tried a bit harder, like not letting drivers into their auto-install database that put things in the wrong place. ST could also have bothered to put their vendor and product ID in the DFU application note, and maybe include the word 'driver' at least once.Can't be bothered making a github account, but it would help to raise an issue onhttps://github.com/free-pdk/easy-pdk-programmer-softwareabout adding Windows instructions for DFU, either to use the ST tool which should work with the auto-installed driver or provide Zadig instructions. It currently says to follow a guide on the dfu-util site which I can't find; it just links to a libusb page which also doesn't say how to use Zadig, and even the Zadig homepage doesn't mention the 'list all devices' option.

Only downside like you say, slightly lower efficiency of 96lm/w vs 130-140lm/w for competing panels.Plastic seems to be called "prismatic diffuser":https://diffuserspecialist.com/wp-content/uploads/2018/08/p12.pdfWhich is ~90% efficient. I'm going to assume thats taken into account in the lm/w figure of the panel. So the LEDs themselves are closer to 110lm/w.
