Creality cr 10 or FlashForge Creator Pro - Page 1

content: Hello!!first off i would like to apologise if this is the wrong section of the forum for me to post my topics!!Recently i have been wanting to purchase a decent/Professional 3D printer. I came across two striking 3D printers, Creality Cr10 boasted a huge print size and had lots of favourable reivews whilst the Flashforge creator pro has a sturdy/robust design and much better suiter to print filaments such as ABS (Huge plus) , dedicated software and great community. However i have my views and concerns. The creality cr10 , being able to boast such a huge print area, would it be able to print ABS filaments even in customised diy enclosures?The mechanical components would most likely die off before the Flashforge however it is easily replacable but repurchasing of components. However the flashforge has a really small print area when compared to the creality 10, and i myself have not tried or experience printing in ABS and i am a enthusiast in customising my own parts and i know that ABS is the superior choice, while others may compare ABS to PETG i am really curious to know if PETG stands up to ABS and is the creality cr10 more worth than a ready made flashforge creator pro. The difference in print area is really huge and if the creality CR10 is able to print ABS. I would love to see views of anybody in the 3D printing world and especially those who owns both or either one of the printers. How do you guys feel about the printer and what is most important?

The corner I was working was not receiving that much light though but light was enough for me to read. I diid not unroll the whole thing.

Wire insulation flammability test videos? - Page 1

content: I was wondering if anyone knows of a decent video testing wire insulation flammability for various types?BigClive showed us a way to test if a wire is copper coated aluminum by seeing how it responds to heat. I tried it with this wire here:https://streamable.com/oo5u0But instead of worrying about the wire, I noticed that the insulation does not seem very good.The wire is a cheap telephone wire type bought for connecting small things (LEDs and such), and it's a really small diameter wire with a few cores (in short, the lowest possible price/quality, regardless of diameter).I''m wondering how would other wires respond. Especially small wires used for connecting things on breadboards and soldering low current things together (small diameter wires in short).So, if there is a video, please let me know.

Questions about Mavic Pro drone Wi-Fi mode - Page 1
Forum section: electronics / general

author: Ben321
author_rank: Frequent Contributor
timestamp: August 01, 2017, 01:34:24 am
content: The Mavic Pro has a dedicated RF mode (which uses some non-Wi-Fi frequencies for controlling the drone) and a Wi-Fi mode which uses the standard 802.11 wireless LAN signals. My questions are about its Wi-Fi mode. I know it has its own built-in router, so it assigns itself an IP address. Then when your Android tablet connects to it it assigns your tablet an IP address via DHCP. My question is, what address does it assign itself. In the most basic wireless network, there are 3 devices, each with its own IP address. There's Computer 1, Computer 2, and a router. I would like to know, in a default (not hacked/modded) Mavic Pro drone, what IP address is the router assigned, and what IP address is the Mavic's internal computer assigned?I need to know these things, because before I buy a drone (Mavic Pro to be specific), I want to test the Android app to see if I like its look&feel. However to test all of its menus, I will need to make the app think it's connected to a drone (otherwise there are many menus that you can't access). And of course to do that, I will need to configure my home-network wireless router to behave like a Mavic Pro drone's router, as well as writting my own PC software to make my computer send the signals that a Mavic Pro would send (so the official DJI Android app that normally controls a drone, will THINK it's connected to a drone, and send all the signals to my laptop computer that will be behaving like a drone, from the DJI app's point of view). So the first 2 things I need to know are this:What IP address is typically assigned to a Mavic's internal router?What IP address is typically assigned to a Mavic's internal computer?

author: ejeffrey
author_rank: Super Contributor
timestamp: August 04, 2017, 11:35:26 pm
content: My first recommendation would be to talk to people at the company, such as the full time employee(s) you are working with. They should at least be able to tell you more about the process. Knowing what to expect will make you more comfortable, and being more comfortable will make you interview better.Obviously you should be able to explain and defend your intern project, and also explain how your intern project fits into the larger project -- for instance how the constraints on the product affect your design. That may or may not be part of the interview process: some companies may rely on the statements of your coworkers/hosts as to how you did the intern project and have a more general interview. This is the sort of thing you might be able to find out ahead of time.There will be limits to what your host is permitted or feels comfortable telling you about the process. Don't be afraid to ask if you have questions about what to expect, but don't push it if they don't want to answer.Did you have a formal interview for your internship? If so, an employee interview will probably be similar.

Did you know the universe could be 10,000,000,000,000,000 times bigger then the 90 Bly diameter that we can see if the theory of inflation is correct, which most physicist's agree that it is! So far I have figured out the universe weighs more then 1 kg, but my math needs some work. The universe has 10^80 particles and a volume of 10^120 plank volumes. You would think it would be bigger but those are insanely bigger numbers that you can't possibly "see". The most of something I have seen is 1,000,000 which was a 4 sq ft piece of paper with 1,000,000 periods printed on it which just appeared as a blur when you looked at it from more then a few inches back. Then think that the US government wrote a check for trillions of dollars that would be 1,000,000 of those sheets of paper, that I can't fathom.

content: "Don't worry, it will buff out . . ."Seriously, it looks like the lUser laid the iron on top of the station with the cord holding the handle end down then something snagged the cord tipping it till the barrel touched the edge, and it all rapidly went bad from there.Pare back the damage with a sharp knife and repair with fibre reinforced car body filler, then spray-paint.If you've lost your <expletive> soldering iron stand, its quite easy to improvise something safe and effective. The simplest DIY stand is a couple of 1" wide strips of wood a bit longer than the iron screwed down to a baseboard at a slight V angle so the iron cant slide out if the lead gets tugged + a stout wire or metal strip bridging the side strips with a U bent in the middle as a heat resisistent support for the barrel. Its low profile so is very hard to knock over, the hot parts are difficult to touch accidentally as the wood strips guard them either side, and as the bit is accessible, its also handy when tinning wire ends as you can leave the iron in the stand, hold the wire in one hand and the solder in the other.

content: You can probably order the original probe from Keysight. Pretty sure it is the same they have been using since the 54600 series. Expect them to be expensive. They certainly are on eBay.Hereis a kit which uses the ubiquitous 18-channel HP logic analyzer pods together with a flat cable and some custom adapter boards. Note that this is somewhat inferior to the original, which used a coaxial cable instead of a plain flat cable. There weresome indicationsof signal integrity issues.In my opinion $60 is not particularly cheap. It comes without ground leads or grabbers for the pod. You could buy a pod with grabbers and ground leads for a little overhalf that. Search for (hp,agilent) (pod,pods), and look for one with accessories. You could use an IDE cable (make sure it is one with all the 40 pins present and use the part before the twist), but you would have to design your own adapter boards. I believe the pin-out is just straight through, so might even be able to build it on veroboard. There was also some discussion in the topic about cross talk of old logic analyzer cables that might fit.If you feel like going the DIY route, you can find the equivalent schematic of the pods on page 47 and the pin-out of the pods on page 71 ofthis document.

LED lamp with dimmer flashing - Page 1

content: Okay, so my daughter has this nice desk lamp with LED and a dimmer. Recently she moved into another room in our house (different floor, different electrical course), but when I plugged in this lamp and turned it on it just flashes briefly at approx 1Hz. The intensity of the flash seems to correspond with the dimmer. It had worked fine only 5 minutes earlier in the old room, so I took it back down and tried it again and it worked just fine. I then took it upstairs where her new room is and tried several sockets on the same floor and the same problem occured. My first thought was that there's something interferring so I unplugged out all electrical equipment on this course (TV set, heating cables, computers, some smart lightbulbs etc, in short; everything), but the problem persists.Has anyone experienced something similar?

There is only a small window, and the 3D printer/CNC/Laser and its stuff obscures most of thatbut its was the only space available. So on to the illumination.Cheap imported led's are aplenty, some better quality than others. I opted for warm white as the colour index or CRI is a bit better than the cool or daylight variety.The ceiling lamps were first, 3 warm white (2700k claimed) were installedI managed to find a led diffuser and installed that under shelf. One strip inside the diffuser and a second bare strip next to it. The diffuser shields me from glare as well.Both strips are powered on in this image.I used my light meter to take some readings (fairly close to the standard), and my iphone app to read the spectrum:So on the bench measurements:Colour temp and Lux level on the bench. 1844 Lux on the bench top level in the area I do most work. The LED strips stretch the complete length of the bench, 2.5m
