content: I have owned the Palette 2 from Mosaic for a few months. And it is a really cool concept. It takes up to 4 filaments and cut/splice them into one multi-color / multi-material strand that is feed to a normal single-color 3D printer. This allow multi-color prints, or more important to me, multi-material prints which I use to print water soluble supports for complex objects.But some of the design decisions have seriously made me drop my jawI have often wondered how someone able to make the mistakes found can be smart enough to actually make a product at allAnd it appear that their standard move when someone question this design perks is ass up, and head into sandSo I went ahead and made a couple of videos analyzing the design of some of the key components of the device, and demonstrating the awesome results they leads toMy latest video is the most thorough one, analyzing the filament buffer system, and various other bits and pieces:And this one is about how they designed in a trap in the filament path which can cause some spectacular failuresAnd here is the playlist where I add all Palette 2 related videos:https://www.youtube.com/playlist?list=PLyiqJefkCvt11gphUmheejue75AnW6E5mI bought a 3D printer to make cool enclosures for my electronics projects.

content: I watched an EEVblog youtube video, (video below,)detailing a fairly priced microscope (image below).The scope can be raised or lowered, andthe board can be shifted left to right under the microscope, butlarger boards will hit the stand if the technician wants toshift the board toward or away from themself.We purchased itfor our technician who nowadays has poor eyesight, andit works great, but many of our PCBs are very large;larger than is easy to work with under this scope.Is there any known simple attachment,such as (but not limited to) a slider with a tightening screw,which would attach to the unit and implement this additional degree of freedom?Slightly unrelated:We thought a track system would be perfect,such as those used in 3D printers, (see second video below,)(Has anyone ever tried this? A gliding microscope on a track systemwhich can effortlessly lock into any position, likely with a digital display?)but really any robust solution would do.,,

Graffiti on the front of my bench courtesy of the little one.Got to low in power and you will always want moreSeriously bear in mind your eye safety and guard the gantry area from casual glances even if you are using glasses yourself others may not be. And buy decent glasses not the rubbish ones offered with the lasers.
micron mesh size for vacuum pump protection? - Page 1

timestamp: May 03, 2019, 04:55:53 am
content: I want to add some hardware to a vacuum pump, mainly a bleed and a pressure gauge. I might as well put filters on it, especially on the bleed.What mesh/micron size pourous metal foam filter would work to protect the pump but not clog? I think two would be a good number to use, a fine and coarse one.

author: Kleinstein
author_rank: Super Contributor
timestamp: May 03, 2019, 08:31:32 am
content: A filter in the vacuum is difficult because it would represent quite some flow resistance and often has a large surface area. So it would be a slow thing.So I would better have the filter at the air side. There are commercial fine filters for compressed air. Two stages sounds like a good idea, though the troublesome dust is likely still that part that passes the coarse stage anyway and than slowly degrades the fine stage. With not that much air needed (compared to the compressed air needed for paint spraying) to fill the vacuum chamber I would expect the filter to last very long.

timestamp: May 03, 2019, 09:42:14 pm
content: I meant to have the filter in the vacuum bleed (vacuum level decrease) valve. It should not require high flow but I will do the math on the filters I have in mind with pressure drop. I was just wondering what would work well to protect the actual pump from damage so I know what pressure drops to calculate for different insertsI can clean what its connected to, but if I want some particular pressure for a long period of time, it would be good that the bleed air is filtered because that will suck in alot of atmospheric crap (not a nicely cleaned chamber).

beat cost of buying ground blanchard steel by having someone do it for you? - Page 1

content: So I need some ground flat bars for my welding table. I bought a few but there was a problem that occured between me and the plate manufacturer, so I just have two cross bars that I bought a while back. On top of these cross bars I want to lay ground flat bars and have pins at regular intervals that stick out of the side bars that I can put the top bars on to change the spacing between the plates on my table.I would want 3x 6x36 inch flat bars, and 1x 12x36 inch flatbar, so I have 6 inches of free space I can shuffle around. At a thickness of 0.75. The idea is you can lift one of the plates up and put it ontop of a different pin set (i.e. if you want to make a mostly solid surface that is 30 inches long), or if you want a 12 and equally spaced 6's. 5x36 might be accpetable too, I need to think about it.This is the best price I foundhttp://www.niftybar.com/files/2415/3920/0903/PriceListLO_9000_1_2017_1.pdfThe materials cost is 780$ from the website (cheaper then mcmaster). Weight is like ~300lb. Dunno how much shipping would be.It will not be used for hammering or feature a heavy vise etc. Just precise welding work and general work if it has a piece of wood on top (no banging, punching, etc). Like putting something small on top and putting screws in or whatever. Not working with nasty stuck shit. I want to build a wooden cover over it (like 3/8 inch nicely finished wood with a over hang) that I can put on the table when there is a grinder near by. And maybe a another cover made out of sheet steel that I can put over the top bars, if I need to do something nasty like flux shielded welding (like [ shaped peices of sheet (stainless?) steel with a soft interior liner that would sit right ontop of the blanchard plates like a blanket.Can I do better by buying non ground flat bar and sending it to someone for grinding?

content: It is a subjective question. The price of steel in your area, how far away the grinder house is, and how much they charge for your piece vs using their stock. All you can do is get estimates. Rates vary across the nation.Blanchard ground is nice, but not a requirement.Over the winter, a close friend wanted to build a new table, but since he knew I had a mill with a 11"x58" table in my garage, I let him rope me into machining the all the surfaces of some plates for him that were the same size as you are doing, at 6" x 36". The finish is as good or better than blanchard and I drilled and tapped a few holes in some of them for holdowns.If you know anyone that has a large mill and are willing to pay them for dulled or broken cutting inserts, It is the cheapest way to go, but not many folks have a machine like that in their garage.Well, He does owe me helping pull my truck axles this summer.(edited for spelling)

It's so top-heavy that a standard iron rest falls over and I really don't want to unplug it and let it cool just so I don't have to hold it with my third hand while readying a board for part removal.I suppose I can make a custom rest for the bench, but maybe someone has a clever solution already?

content: The whole thing is easier to explain if I just show a quick video(this video doesn't belong to me)https://youtu.be/UHZAOwGzMgIThis is a free simulator for modules that are put into racks in real life and wired together to make music. The real hardware goes from $40's to the thousands and rare vintage can go for even more not including the cost of the many cables needed. The simulator is designed for Linux but also has active development ports for Mac and Windows, all in open source for the most part..The basic program is free and then most of the modules are free as well but some of the module makers want money because of it being an open platform with no rules against it and to be fair most of them put enough effort into their work to ask to be paid for it.As an electronic engineer I've found this to be fun and educational because it simulates volts, amps, and waves as well as logic programming in some cases. It's a total toy for EEs! I don't know much about music but that's okay because there are arpeggiators, in-the-key-of tuners, beat pattern regulators, and other short cuts to sounding good without much talent.The song in this link wasn't played on a piano roll(a graph plotting notes for the whole song) instead it was the result of a few basic pattern generators manipulating other basic pattern generators of just a few notes. This makes musical construction for novices like me easy.It also takes inputs from the soundcard sources and has a lot of spectragraphs, scopes, meters, and key matchers simulated in the program so it can be used as a cheat for 20Khz-20hz analyzers. Just don't forget to be careful or else "BANG! You'll blow you're" -soundcard! I've hooked it into audio outputs on radio equipment and it works great for that.One conceivable use is also for robotics as it can also put out control voltages as well as take them in through midi as well as analog signals in and out through audio channels also having logic modules with ifs,ands,ors,nands,xors, and so on. I have not tried this however and if this causes your robot to rebel I will not be held responsible.(Information on Modular Synthesizing )https://en.wikipedia.org/wiki/Modular_synthesizerhttps://vcvrack.com/

I've also provided some options that I like that are ideal for heavy gear.https://www.eevblog.com/forum/testgear/quality-shelvingracks-deep-enough-for-boat-anchors/1. Low profile shelving mounted behind the bench, heavy duty side shelving.2. Heavy duty bench with built in shelving.3. Heavy duty shelving behind bench, suits a large collection of boat anchors.4. Another example of heavy duty bench with built in shelving.5. Long span bench and built in shelving which uses tube steel rather than right angles.Those heavy duty shelving examples are different from long span however gives you an idea of the options. Long span ended up being a cheaper and stronger option for me and suits if you have more space. The color height and shelf material in all these examples are usually optional.The power solution I chose for my shelvescan be found in this thread.

If you are running multiple spans look for the verticals that have parallel keyholes otherwise you will have to stagger your shelves or buy extra verticals.Hardware stores local here sell a variety of dressed timbers for benches, these can be cut to size so you can have quite a nice steel framed bench if you want to.

I am trying to avoid the wall mount shelving if I can help it as I am not sure it will how many transformers. and I found that if I had a decently wide bench the test gear was a little far away to be useful if you go more then one tear in gear. The lap space is taking shape it is a decently long span and I am even considering using a 19 inch server rack for some gear to get the density up as I need it. Everything is starting to come tougher. I am even contemplating ESD flooring.

content: If you are going to paint sheet metal, with old ass oily paint (aluminum), does a primer matter?For aluminum I noticed no real difference when I scrubbed it down with ajax and heated it nice and hot with a torch before painting.How does THIN steel fare? If I blue the entire thing I am painting, then paint right after it cooled down as not to effect the paint, do you still need a primer?I understand it has something to do with surface tension/adhesion.Doing something thick is obviously an issue, because of thermal mass. But stamped parts? What exactly does it do (this would be the non-corrosion inhibiting primer. that shit is way too expensive).It would be descaled to shiny bare metal and then heated with a torch. Its a large object (sawhorse that folds up).When I play with it before, the burned metal wets with water like paper (does not bead up at all). It would be painted with a spray-gun.Yes I have primer but I would rather use it on my other restoration projects like vise, generator parts, etc which are not burned easily or should not be burned. This thing already got frankenstein wood. And its actually easier and faster to burn it then to paint primer and wait for it to dry and come back and do it again and wait for it to dry. And I don't really enjoy spraying chemicals or using respirators or being delayed by wind conditions. Want to keep that down to a minimum.Also, would running it over with a plasma cutter hooked up to argon do the same thing? maybe with some kind of diffuser/obstacle in the main plasma stream to break up the heat over a larger area? Without cooking the metal so hard. I thought about attaching a ceramic rod some distance away from the nozzle so the plasma hits it and spreads around it (perhaps two layers of rods that act like channels , stacked in a 'pyramid' fashion. Or I guess just a conventional plates with holes.

I found that it works in between 80 hz - 20Khz. I don't know how useful it is, but the concept is neat.Anyway, the program and documentation is posted therehttps://www.ticalc.org/pub/83/asm/science/It also has a schematic for some external supporting circuitry.

content: I second amlu's comment, I have the Engineer PA-9 (same as 20 except for smaller terminals) and it works well for the main crimp. What it can't do is the 2nd crimp that grabs the insulation on the connector pins I use, which want the metal wrapped around the wire, not pierced through it. I use some jewelry pliers for that and if I'm careful it comes out OK.But forking over the the US$350+ for the Molex tool is probably in my future.

content: So I got a used Metcal MX-500and might need to buy new tips. Thermaltronics has some cheaper tips in general, but there are some good deals on eBay for Oki/Metcal ones. Are Metcal tips better than Thermaltronics ones? Thermaltronics also has some "Power Plus" tips and Metcal has some optimized tips with "STTC-xxxP". Are those worth getting?Also, most Metcal/Thermaltronics tips are the 700 series ones that have a temperature of about 413C or 775F. That seems a bit high for light hobby electronics work (mostly through-hole). I'm currently using lead-free solder, but wouldn't the 600 series (357C/675F) still have a more appropriate temperature? Or would the 700 series work just as well or better?Thanks

The piece I managed to get my hands on was a Mindray PM-8000VET medical monitor. It has a Blood pressure, ECG and O2 Stats inputs that I have been able to use. In standalone mode it appears to work flawlessly.However, I have been unable to get in to the maintenance menu to get the unit on to the LAN so i can pull information directly from its network port. There is a User Key and a Factory Key option in the maintenance access window. The VET it came from has no idea what either password could have been.I was hoping there would be somebody here who might have come across this sort of equipment before and have some tips and tricks on getting the full potential out of it.Regards,David

The iron works properly and the heating element workd as it should.I was thinking if there is anything to gain from an upgrade to LR 20 or LR 21? I have to admit that I don't do virtually any SMT work, so I guess antistatic is no big deal for me. The heating element and the tips are the same for all three irons. But I can't find any way to understand what the differences can be. Any ideas?Thanks in advance

If you get interested in amateur radio then it does not cover any of their international HF bands, unless 30kHz is a misprint for 30MHz!.From its specifications that it was designed for testing VHF stereo broadcasting systems.Tony

content: That unit was designed specifically for servicing and aligning FM stereo tuners and FM/AM radios. It actually has extended frequency ranges, when thought of from a servicing viewpoint. By the way, that is 100khz to 30mhznot kHz. There is a fair amount of frequency and modulation flexibility. It can do 455khz and 10.7mhz IF alignments for instance. That is a great price for a unit of this quality. I would go for it, even if you don't use it right away.

Would any of those work for IL-AG5? Any other brand/product you can recommendRight now I'm using basic crimper and crimp the "cheeks" around the insulation and the wire separately but the results is for the most part bad. At work we have molex crimpers but those are too wide for the IL-AG5.In the best of world there would be a tool that I can use for both Molex and IL-AG5.

content: Hi there. I have the Engineer PAD-01 kit. It really is the only one that can be recommended at this sort of a price point. You can choose either PA-09, PA-10 or you can but the individual parts of the PAD-01 kit separately, (and forego the padded case) which are named like PAD-12, PAD-13 etc. including the handle or just the interchangeable die itself. Doing so is really the cheapest way to aquire the parts of the PAD-01 kit. Whilst also obtaining the maximum range of crimp sizes. Both large and small.However finding the individual parts (either on ebay or aliexpress, or elsewhere) can be a little hassle. So if you would rather buy the full PAD-01 kit then the cheapest I found it for was via hobbyking, including an initial discount / as first order (new customer). It came out to be around #75 GBP for me including the delivery.Hope that helps. BTW here is more information about these engineer crimps. I have documented my findings in the comments section. But opening the video in another tab with the link URL below (which will highlight the specific youtube comment as topmost comment). Kind regards.

Digital magnification of the image doesn't improve on that. You could put the image up on a 100" screen, and thereby get a lot more magnification, but you could still not see any more details.
