[@astrogirl1usa]

Thanks Dave! My son is 17 and very interested in electronics. Watching your videos are the first thing, after eating, that he does when he comes home from school. :)

[@Tangobaldy]

Esd protection is important. A few years back i pulled a expensive graphics card out its bag. I felt the spark and the card was trashed. Dave your videos are awesome.

[@OpenGL4ever]

Depends on where you live and what the atmospheric humidity and temperature says. For small electronic parts, ESD is a must, but for larger boards it's not that important and when your atmospheric humidity is high, static charges won't build up that much.

[@stclairstclair]

Thank you dave, At one point my bench was tied directly into main earth ground, I understood this was bad when i watched Daves "how not to blow up your oscilloscope" video, this too was a nice reminder and understanding of such a simple mistake on my part, Dave America loves you!

[@jimmiechorkc2467]

Dave, for the power strips: look into rack mount power strips. I have one mounted under my bench, 12 plugs, and it works great.

[@QuantumFluxable]

It feels so good hearing a person speak English yet not use Imperial. :)

[@milanfixer]

Yes! I've heard a guy say: "It's in metric, so it's useless." Lmao 😂😂😂😂

[@companymen42]

Technically, the US is metric, but the Senate committee to switch from Imperial to metric was never funded.

[@edwardmonsariste4050]

Milan. The only metric that I understand is the size of a 2 liter of Mountain Dew. Yeah, job security for my dentist...

[@mikeadler434]

👍👍

[@vhfgamer]

@@milanfixer Metric exists to be converted to real measurements, so that it may be used.

[@drewc9947]

My first woodworking project is building workbench/pc desk over the US Memorial Day weekend, since I got some extra time off. I can’t wait I tied a washer to a string, held my arms bent at the elbow, and measured how long it was from the crease of my wrist to the ground. My bench top will sit just below that, so I can stand and type. Gotta be ergo!

[@gosubreboot713]

That's funny, I've just taken up electronics as a hobby after stumbling across Dave and mjlorton. Yesterday, I built a couple of shelves and a workbench and then saw this vid today. Feel like I'm wired in. Love the safety aspect added in to the vid, it's important for all us noobs just starting out, wish there were more though.

[@Nicholas2011ist]

I live in chile and it's like any other country. What do you mean by a strange place? We may be a small country, but I still love it. Cheers Dave, Keep the vids up.

[@BenChilds]

Dave, might I suggest a low shelf addition to that workbench? It would give you added storage space as well as a place to put more gear / tools and the added weight to bottom of the table would give you some extra stability It could be done cheaply with a few added brackets and lower quality plywood to keep the cost down.

[@electronicsNmore]

That lab would be a playground for me. :-) I like that work mat. Good video

[@Iamfatbrain]

EEVblog is the best, keep doing your thing ;)

[@quincy8557]

Very professional job Dave

[@alro7779]

4:58 Actually I am a Chilean viewer, Dave! Greetings from Mexico! You rock!

[@pd1jdw630]

Somehow when Dave said “talking heads shots” a song popped up in my head.

[@Britec09]

I be looking to build something like these in my new workshop, thanks Dave

[@williamvaughan1218]

dam man I like what you got present already nice.

[@Satelitko]

I like how you say "I damaged myself" instead of "I hurt myself". Like you don't feel pain or like you're some kind of robot.

[@poprawa]

In Poland is recommended to have a residual-current device cutting off power while ~25mA is driven by main earth line, you can be shocked by this line but its impossible to kill you so you can be connected to main earth without resistance and its pretty much safe.

[@ItsEverythingElse]

I would still double screw each angle bracket side. It doesn't hurt and I would think it would help stability at least a teeny bit.

[@JGARCIAR85]

Nice project and beautiful family.

[@ecercuit]

Hi Dave, I really likes your contents. You inspired me to share my Electronics knowledge and experience on KZbin. You're on my top featured channel. I worked with Rob Weir at EMC Tech and Austest you previously feature on your content. I have built also an Electronics Workbench. I have used the same ESD mat you have and I will do content on this mat to demonstrate ESD testing on the mat using ESD Gun, 500MHz oscilloscope and possibly a HV differential probe and how does it differ from the one sold on eBay or Amazon. Nice one Dave!

[@Landrew0]

The more space you have, the more you seem to need.

[@Wes8761]

Gotta love that back to the future plate 😂

[@antonwictro1627]

you should/could put the planks between legs in an 45-degree angle to create triangles that would stabilize the built ten-fold.

[@Videoneer]

+100 awesome points for the Hack a Day shirt!

[@redtails]

11:11 starting to look more and more like your old garage, to be honest. Well, it's not a bad thing, lots of space to put stuff, lots of it within reach

[@Vandwo]

11:20 saw some Java book there, hehe, Anyway great job as usual, Dave never disappoints us. Find your tips and advice's always useful!

[@nicksokolov6024]

Dave , could you use steel ?, I used 40x40 welded section with Marine ply decking on wheels, stuff on top use 30x30 Aluminium extrusions, IKEA for robotics. You are a guru on electronics and you are absolutely right about bench space.; "there is never enough space". Aso mention - project boxes - sometimes one needs to pack up a project into a Fischer type box waiting or hunting for a part. Keep doing the EEVblog . You speak my lingo. I did love your drone repair video and your expertise in flying it .

[@KamFiction]

Hey Dave, I just wanted to let you know that I used this video to calibrate an audio band-pass filter I'm using for a real time RSA audio encryption project. :D

[@spelunkerd]

I didn't realize ESD matting is so expensive.

[@EEVblog]

spelunkerd The good rubber stuff is, yes.

[@tra757200]

Missed your little helper on this build.

[@BurnabyAlex]

14:40 you could get a watch repair shop or leather shop to make your watch strap out of anti static strap material. I once tried measuring the ohms per meter of a bench mat at work, and had to measure a few mm apart to get a good reading.

[@jusb1066]

check into the water based varnishes, they dont smell at all, and are just as resistant as the old oil bases, plus cleanup is so easy, it applies so easily with a foam brush, perfect and dries in about 30 minutes. i would seal the surface myself for spills, it also helps with rubber feet, suction cups etc to grip and should help your mat slip less

[@berni8k]

I built a new workbench about half a year ago and yes water based parquet varnish is the bees knees for this. Does not smell at all, drys really quick and makes the surface really easy to clean. Also as a bonus once this kind of varnish cures over a month or so the surface becomes really hard so it becomes very scratch resistant and protects against dents if you drop heavy stuff on its edge. This helps a lot on such a soft wood as pine.(My old small bench was made of pine because it was really cheep here, but i found its too easy to damage. You can leave a mark in it using your fingernail if you try) But using a hard wood and varnish makes it resistant enough to drop a hammer on it without damage.

Hello from New Zealand

[@JBGecko13yt]

Thanks for the idea! I made a similar bench tonight from lumber

[@xjet]

Believe it or not Dave, those 70mmx70mm posts probably cost less in Australia than here in NZ. That's the stupid way our economy works :-(

[@EEVblog]

***** I'd believe it. We have a few things like that.

[@city4593]

Soooo... I followed Allan's advice and got Hyezmar's Woodworking Bible. It's great for beginners, and has some advanced stuff too.

[@aserta]

You could mount the scope on a square that has the round base's circle tangent to the 4 centers of the square's sides. With screws. Then, that piece could be mounted to the bench on the back side of the bench with one of those flat plates with many screw holes you can find in pretty much any decent hardware store. I did the same thing with my mini bench press drill. Didn't want to drill the surface so i made something very similar. P.S. you can adjust the distance from the wall by simply making one side of the square longer. edit: i can draw it if you want.

[@USWaterRockets]

What's being "censored" on the whiteboard at 11:30 in the video? Something is "fuzzed out".

[@JustinAlexanderBell]

Doesn't that defeat the whole purpose?

[@USWaterRockets]

He can say what it is without giving away anything private.

[@lmiddleman]

Dave reveals a few things when he swings stuff out of the way near the end of the video. I can make out "... MONITOR PROJECT" and "MEMRISTOR". Fascinating.

[@USWaterRockets]

Good find!

[@tsusec]

you can se on 0:58, that on the board are som words.... but what it says, IDK !

[@kalhana_photography]

Thanks for the video! I'm quite paranoid about ESD as well. Got a mat from Farnell for quite cheap (1687904) is rubber conductive/dissipative one and feels ok quality but it keeps trying to roll back on it self, I have taped the edges with fibre tape. The one you use seems to be well behaved, I guess that's why it's quite expensive. Mine came with 4 studs on the 4 corners, the ones that are on the closer edge are handy to plug your wrist cord into while the one at the back is connected to mains earth.

[@Morkvonork]

I build my shopbench out of multiple 60€ kitchen under cabinets. That way you can have not only have stuff cluttered on top of the bench but you get drawers and doors to clutter too :-)

lol, just had a thought. I remember one of your lab clean-out videos you said you were a hoarder, now you're hoarding benches :P

[@DavidAndersonJC]

If you can, I would be very interested in a more complete description of your grounding setup, and general suggestions as to proper grounding for an electronics lab setup. Very relevant to my interests at the moment as my plugs lack mains earth (50s construction for the lose!), and as I look to upgrade that I'm also trying to figure out what other measures I should take to have tip-top clean grounding for my hacking. Thanks for the videos, always very informative and entertaining!

[@Wesshaw1996]

I love your show keep up the good work

[@toolhog10]

Excellent video.

[@rubber20021]

esd is a great precaution to design in and use, but nowadays the actual semiconductor is buffered... but still a great idea to use...the just in case may always happen!

[@sakohq]

Dave, protect your desks with water-based varnish, there are some on the market designed for protecting children children toys, so You could even lick or bite Your desks :). They are not smell at all!!! I love them :)

[@holderbee7811]

Hi! I have to stop watching EEVBlog videos for a while.. too addicting! But I'll catch em all up later Dave

[@MyCatTookOverMyChannel]

Can you do a video showing how to properly mount power strips?

[@KX36]

Yeah, I was wondering when you have that many power strips is there a way to hook them up and reduce the radiated 50Hz? Probably not I suspect...

[@UberAlphaSirus]

KX36 SWA with star earthing would be a good idea. But your right we won't see it. earth loops a plenty etc etc

[@TheChipmunk2008]

[@UberAlphaSirus]

***** Terminating would be fun to watch :D

[@JustinAlexanderBell]

The previous desk never looked very sturdy, I notice if you bump into it a bit the whole thing wobbles.

[@AllenSunnyD]

I don't know what varnishes/stains you use but the ones here i get in the states dry over night and have absolutely no smells or oders.

[@HillOrStream]

Wondering about those lab stools, where you got them, how much in cost and any ESD considerations to them?

[@necessaryevil8615]

I always thought that the Australians use the SI-system, but then you mentioned your height in feet. By the way, isn't plain wood anti-static enough, at least for the most components? Yes I know it can be worth to spend that kind of money on matting, but it is still a lot of money!

[@cemx86]

I thought that you were putting the new bench perpendicular to the existing bench. My thinking was that it would allow more room in the aisle. Then again, you could add a seventh bench at the end to form a U. My 2 cents (USD of course).

[@enkisonofanu2301]

It's wobbly

[@JesusvonNazaret]

make another "cleaning the lab" timelapse video, maybe with viewer support ;)

[@94PeterQ]

Should I plug my ESD mat to my wall outlet (ground pin)? My oultlet should be checked? If your answer will be yes - How I can check this (for security reason)? Second question is how I can grounding with alternative method opposite to wall outlet if I don't have devices dedicated for electronics (I am beginner). Maybe some video about that. I am from Poland so I have 230V wall socket with european version. P.S. Sorry for my English ;/ I still learning...

[@dermeister992]

Chilean wood.... i want one of these oscilloscope :D

Dave, I'm curious: what do you do about fumes? I see no windows present. And I'm so worried about fumes that I usually refrain from soldering stuff - and I love it. And you look like a military guy, haha!

[@xamesm]

Do you use glue for any of the wood connections?

[@doodh_jalebi]

Oh! I see a JAVA book at 9:20 !

[@RyanUptonInnovator]

Those grounding panels off ebay do not seem to have their button connectors linked to ground.

[@proluxelectronics7419]

I would not recommend wiring the earth into a standard wall plug as the wire is easily stressed and internal conductor damaged. Buy a ESD molded plug with a press stud earth fitting made for the job.

[@BefetaRemaneMedalicho]

[@cemx86]

How much in total did the materials cost you for this bench (minus the labor of course)? The top is solid (expensive) pine? Not plywood? Is there a reason for the extra expense for the solid pine besides look?

[@EEVblog]

[@fohdeesha]

[@abeleski]

Hi Dave. That mat does not seem to be available anymore and so your link is broken. I am trying to find some for myself.

[@Nichoalsziv]

The backing needs to be grounded so the disipative side can dissipate its charge to it? I don't really get how that works or if i am understanding it correctly.

[@EEVblog]

Stragemque Correct.

[@mshahabas]

don't you have 'Type A' 30mA RCD installed in your labs mains input? for even more protection?

[@mshahabas]

I meant 'more basic protection'

[@OpenGL4ever]

EEVblog Dave, you will need a "Gratnut" and "Gratleiste" (don't know the English words for those two things, but here is a picture of both de.wikipedia.org/wiki/Datei:Gratung.svg ) in your tabletop. Without such thing your tabletop will warp and curve in the long run. I also highly recommend to use at least some sort of linseed oil to protect the table from woodworms and Liposcelididae. en.wikipedia.org/wiki/Woodworm en.wikipedia.org/wiki/Liposcelididae In it's natural unprocessed form lineseed oil will dry very slowly but it won't stink much. But you will probably not have a none dry oily table for weeks, so i recommend to use a industry lineseed oil product or wood finish based on lineseed oil, those dry with the help of additives much faster but they might stink for 3-4 days, but it will at least protect your tables in the long run. en.wikipedia.org/wiki/Linseed_oil#Wood_finish In the end it is better to use some sort of wood protection. And the right oil, like lineseed oil doesn't stink as much as Lacquers.

[@TheLameTechGuy]

I think its time for him to get a bigger lab.

[@PiotrSarnacki]

Probably that's a silly question, but why is it a no-go to chain ESD mats?

[@peeeepsi]

+Piotr Sarnacki As long as they are all connected to the same ground level I dont know why it would be?

[@tankgrrl]

+Piotr Sarnacki Because the loss of any leg in the daisy chain removes protection for those points further down the chain.

I have a question or two, I'm building my work bench covered with ESD mat which is connected to ground, and I'm using a 30V 5A bench PSU. Now is it right to work with PSU over ESD Mat or I'm grounded? Is it safer that my feet touches the ground or not? and last question, how dangerous is 30V 5A PSU?

[@Thorsummoner0]

Woah, where do you get a piece of wood that wide? Out wood is all made of sawdust and glue in the States!

[@EEVblog]

Thorsummoner0 It's smaller strips glued together at the factory.

[@USWaterRockets]

In the USA, why not just get a nice piece of maple plywood? 4'x8'x0.75". It's about $80 from a good home improvement store. Pine is pretty awful for a table top because it is too soft.

[@ChrisRovers0]

You can generally buy glued together "project panels" at most big box stores.

[@USWaterRockets]

Yes, but the maple plywood is so much denser and harder that it won't get all dented from working on the top surface. Pine is so soft.

[@Thorsummoner0]

My comment was somewhat sarcastic, cynical of the cheap crap that cheap manufactures sell. Doesn't plywood often come with a MDF core though?

[@AdminTechnopedia]
