It's an aggregator for about 600 data feeds (ems, distributors, manufacturers, backend parts management). I have tried to make a true full-text alternative (including parametric data faceting). Early days...So I love it myself. But loving my own product doesn't tell me much. Can any of you guys give it a whirl with typical keyword, parameter, part number searches to see how it holds up against your usual search sites (octo part, alldatasheet, mouser etc)?No need to hold back if you find it useless. Honest feedback will help me iterate.Links:https://www.buyparts.io/https://www.buyparts.io/0.1uF%200603%20capacitor.html

For example mounting type appears to only have two options, Through hole and surface mount (at least for the part I was looking at). It would make more sense as a user in my opinion to be able to select one or both of those options without having to search. Other than that looks nice.

content: Thanks elecman14, that would be great. I originally started down the route of multi-select dropdowns. I had a couple of problems. First was that for many of the parameters there could be hundreds of options. So the text of the dropdowns would make page sizes large. The other problem was with the data sources. Because there are so many different sources there is no standardization of values. For example the same value could be written differently by 20 different data sources.I'll certainly take another look at it. Maybe a hybrid of freetype and multi-select is possible.Thanks again for that feedback.

content: Please don't use that font! Everyone can read your message very well if you write with the default font.Wow! How did you manage to produce such a damage to the poor PCB? The hole you created at C907 is probably beyond repair. Not only the cap is missing, but parts of the PCB as well. What you see in the hole is the layer below the top layer. It could even be two layers below the top layer. The 'good' picture seem to have vias in that area. So you don't know if there traces missing. That's far from simple to repair. I personally would say: That's a nice paper wight.By the way: At area '2' there seems to be a resistor (black package). But what values: I don't know.
Does the BF840 have an internal diode ? - Page 1

content: Hi, I have just measured some BF840 with the DMM, and it seems that they have an emitter-collector protection diode. In the data sheet there is no mention about an internal diode, so I am a little surprised.They are SOT23 packages marked NCW, so they should be BF840 made in China for NXP-Philips.Does anyone know about that ?

author: David Hess

timestamp: June 16, 2018, 03:21:47 am
content: I agree with blueskull; newer DMMs use a higher test voltage to support testing of blue LEDs and this might be enough to exceeded the 4 volt base-emitter breakdown voltage of the BF840. There is no way that transistor has a parallel collector-emitter diode.Note that base-emitter (or collector-emitter) breakdown damages the transistors lowering hfe which may or may not matter in the intended application.

I have used a Fluke 179, and it puts out 7 V in the diode modeI took 2 NEW transistors and repeated the measurement with a Simpson VOM that uses a 1.5 V battery.In both transistors, the direct resistance base-emitter and base collector are both 20 ohms and the resistance between collector (-) and emitter (+) is 26 ohmSo, there must be another reason for this strange behavior

content: The term gamma radiation is normally used for electro-magnetic radiation (usually x-ray range, but could be even down to IR) emitted from nuclear processes. So there can be some x-ray, but should not be any significant gamma rays from lightning.There are also quite some radio frequency pulses that might fool detectors for gamma rays to detect a wrong pulse.

You can control a gliding aircraft though, and avoid crashing into someone’s conservatory. In the case of a fire on board though, all bets are off.

Unstable SLA Voltage or Faulty DMM - Page 1

Last year I had them connected to a solar panel for most of the summer to try and revive them - I think one or two were still OK volts when I got them, and one was down to 10.5. I let them sit on the shelf over winter and measured the voltages this morning. All three were bouncing around between 12.5V and 14V. That has to be a faulty DMM, right?

For the sake of this survey, I wanted to capture the full spectrum of intents of why people build things. I personally went through years of blowing up transistors and frying chips to get to a state of good understanding. In many cases, I find that people are not so much interested in the technical obstacles at first but simply want a certain idea/feature to work. From the point of view of a person who hasn't done electronics, a path that enables rapid validation of idea may lower the scare barrier of entry to the hobby just like how Arduinos mainstreamed embedded development, and that's what I'm curious to find out.

content: Hi, I live in Canada so colleges offer less in a program than University, compared to USA where I think both are kind of the same. Im looking to do college than go to University in Robotics, or EECS or something similar. Can someone look at the course descriptions and tell me if one offers more than the other because one is 325$ (first link) per semester while the other is about 2 300$ (2nd link) (and if you could explain a bit). Also I see there's some difference in course offerings, I think Electronics and EE is the same but a bit different from what I see, in any case, in the end which is more beneficial or they will teach same thing at the end? (I'm also studying home extra.)

content: The Electrical Engineering programme seems to have a lot of courses in electrical machines and industrial automation, which is different from electronics. This is about big installations, PLCs, industrial automation, etc. You won't be using AutoCAD to draw PCBs, but probably wiring diagrams for a large installation cabinet.Electronics really seems to be focused at using modern electronics components, and designing PCBs/products around them.What are your interests? Do you want to do engineering at a PCB level (which is what you will see mostly at EEVblog YT), or at an industrial building/factory plant level?If you want to get more into electronics, computer science and robotics, then for sure I would pick the electronics programme. The only downside IMO is that it doesn't seem to have as much math and control theory, which will be an useful preparation if you get into university for a Bachelor (I presume?) later.But robotics is a mixed field. You may want to keep mechatronics in mind if you get into university (I'm not sure if college programmes offer this), because it's a wide mix of control theory, mechanical, electronics and software engineering all combined.

Compare that to a normal door where you probably would not be able to squeeze in with that little clearance. Storage space however, which was located under the forward tilting hood, looks pretty small.http://www.entermyworld.com/cat/myd/trunk/trunk1x1.jpg

It might take a bit of reading and research but whether it's FPGA, software, analogue or whatever and it's a project small enough for one person I can do it. I've always completed projects in my own time to increase my knowledge however they are becoming less and less productive as I need to undertake projects that are too big (take too long) or cost too much in order to learn from them. So now I'll just be doing the same old. I'm wondering, what should I do next? I know you can never have too much experience, but I really want to get good value out of my projects and not sure what to do with my skills. Any suggestions from people who might have had this problem would be great!Thanks

And lots of eighties to nineties small electronic items. Games. PROM programmers. Dozens of 20 drawer organizers full of obsolete components and hardware. Tools.Most of the material was stored in not very weathertight sheds and showed the effects. I bought a few textbooks, a nice stroboscope, a sound pressure meter, a relay rack and a few other items for $85. It was hard to avoid picking up more since there were good values, but my space is already tight.
