content: As I wander through the forums, here and plenty of other places, I frequently see people commenting on how they love old electronics, the smell of old electronics, possibly emanating from the delicious polyoxybenzylmethylenglycolanhydride (Bakelite), the warm memories and such.However, for me, I'm sitting out here in the cold, finding that it brings about a whole set of feelings of which none are positive ( that said, i've only been doing electronics since '84 after getting my hands on DSE catalogues ). I feel like it's dragging me down in to a dank basement and drowning me in toxic ooze. That said, a blown electrolyte or tantalum will have me running for the hazmatAm I alone?

Internal network design, hostnames and best practices - Page 1

content: I'm about to do an entire network refresh at home over the next few weeks. Essentially what I have at the moment is a rack full of old gear on one network and a bunch of new gear on a completely different network. There is no routing between the two, partly due to laziness and that the new gear is currently running on the floor in my "office" with LAN cables running across the house.I have a registered domain name (let's just call it foo.com) which currently serves no other purpose but to 'reserve' that domain. I have an Active Directory server configured with the same FQDN, although I've added a subdomain when configuring it (i.e.: internal.foo.com). However I've realised this is a bad move if I ever wanted to expand sites (permanent VPN's etc...) as "internal" looses most of it's meaning. Eventually I'll configure it so I can VPN in if needed and access some other resources.My questions are; How do you guys have your networks configured (I'm obviously appealing to those who also have a "way over the top" home network). I'm trialling 3 VLANs at the moment:10.28.0.0/24 - Internal/Trusted- Clients on this range have access to all other networks10.28.1.0/24 - Trusted Wireless Clients- Somewhat restrictive, but can access most resources on the network10.28.2.0/24 - Untrusted Clients (Wired & Wireless)- Mostly used for clients (such as TV's and my Sonos speakers) which need nothing more than very limited access to one or two machines and basic (HTTP/S, Streaming A/V) internet access to specific domains, nothing more.I'm more just thinking out loud here at this point... it's always good to have multiple pairs of eyes looking over things.

The only difference is the direction the current flows, electron flow current flows backwards, conventional current flows forward. calculations will be effectively the exact same as long as you constantly use one of the two.Looking at the physics yes electron flow is an accurate representation of current. However people didn't like that it flowed backwards. Again the difference is x = -x so just a sign change between the two books.

But unlike the one in the photo I posted, these are really tall, nearing 15mm.I need one like the one in the photo, which is about 5mm tall.Just don't have the height or space for these larger ones inside the box.Any ideas on what these are called, and where I can get them?Need to be able to get them shipped to the UK and in quantities less than 100 without selling a kidney too.Any ideas?Thank you!Jack,

content: Are you sure you want one only 5mm long? 1/4"-20 UNC, which seems to be the standard for tripod mounts, is 6.35mm inner diameter, and the inserts are usually 8 or 9mm outer diameter. Making one only 5mm long would be very prone to getting ripped out with the lever action of a tripod or similar attachment on something like a camera. It's no surprise the standard length for them is 15mm, and even the anchor ones seem to be either 9.5mm or 15mm long.But saying that I have found one Chinese manufacturer that seems to offer them in a 6mm long version, if you insist:https://item.taobao.com/item.htm?id=38645989159&ns=1&abbucket=2#detail(doesn't say whether they're UNC, though...)

content: ARM is available in far higher spec than any PIC. I see PIC32 as a good thing for the low end of ARM, since we need competition to keep ARM honest. At the high end, Intel does the same. At the hobbyist level, there are way more PIC32 in DIY friendly packages (DIP or SOIC) than ARM.How many modern parts with 28 pins couldn't fit in a narrow 28 pin DIP? I remember reading that someone successfully cut down that 28 pin NXP to narrow DIP width, really making it puzzling why it was in a wide DIP package to begin with. The only 28 pin and under things I can think of that have dies too large to fit in a narrow 28 pin DIP (e.g. Flash memory and power stuff) are unlikely to be packaged in DIP to begin with.And to throw in some questions:MOSFET or IGBT?Multibit ADC/DAC or Delta Sigma?Little endian or big endian?

content: Quote from: NiHaoMike on January 02, 2017, 08:07:17 pmI suppose "use" is a somewhat flexible term. For instance, I have not used ARM from the point of view of programming the peripheral registers directly, and certainly not any assembly coding. However, I have used a couple ARM-based systems for minor projects, but only at the C level, so the architecture specifics and benefits were largely hidden.At the register level I have more experience with PIC, 68K, and Intel 8085 from long ago. I find PIC to be as bizarre and unorganized as 68K is elegant and refined. Hitachi H16? from years ago was a moderately good attempt at following the Motorola microcontroller architecture, but it was quite rough around the edges.There is a Raspberry PI around the house, but I've only dabbled in Python on it. Too many projects to really dig into it the way it deserves!

content: Hi everybody,I'm sure some of you (especially those who live in Europe) have heard about the EU directive 2012/19/EU (here in Germany -> national law: Elektro- und Elektronikgerätegesetz)It's about what manufacturers MUST do in Europe to handle the waste created by their products.If you go the legal way you must register and report your sales monthly to an association. And you should be covered by e.g. etakeaway or any similar company for the case you're the happy "winnner" of the container lottery (which means you have to pay for the disposal of an full electronic waste container).I mean it's annoying. You have to pay to register. You have to pay etakeaway and the association on a regular basis. Some guys of another forum did a calculation for small companies. They say: Registering cost is about 300 EUR incl. taxes. Plus 535 EUR incl. taxes every year.So especially for small start-ups with a small amount of budget every year or a hobbist which wants to sale things he made, it's a killer!No I want to know: What do you do if you want to sell stuff here? Ignore it? Selling it in a construction kit? Don't selling anything?Thanks in advance to share your thoughts. Have a nice day or night

content: Traditionally in the US, liability issues are solved through court cases, not sweeping government mandates.There is no requirement for manufacturers to pay for post-consumer e-waste recycling. It is handled in the normal way, as recycling companies take e-waste from municipal waste points and process it to recover its value. If a type of product contains a lot of pollutants, such as heavy metals in CRTs, the consumer-owner may be required to pay a tax when disposing it to ensure it is safely recycled. This is a state and local legal requirement, but it is widespread now.

For MLM it is very low - 1-5% or even less participants get something positive in return. It is worse than working in McDonalds for few hours a week.

The compensation plan is very restrictive and you have to pay a lot of money in order to be able to get any decent commissions. Plus the plan never said where the actual money comes from (just 2 sales is not enough). $150 per 2 sales does not make any sense at all. For the fast startup bonus the ones joining are the ones paying your bonus.I would not touch this one even with a stick. There are a lot of really good MLM companies out there to look for if into that kind of ways to earn money. This one is total crap.

The volume pot is very scratchy, and the mechanical tuning assembly is very hard to turn and the string is wearing out.It has a very very simple design and low part count compared to many of the tube radios I've seen videos of.The board looks really nice and modern actually. Later I'll take some pictures.What else might be wrong with this thing IDK, as Shangoo said in a video I just watched, tube technology can be incredibly robust, and still work when all kinds of things are gone bad.

Pretty much all, and add to that line cords that have crumbled, resistive droppers that are too short, ballast resistors that have crumbled and bakelite parts that are more baked than bakelite now.

content: There are a lot of people like that - don't let people know about the amazing layout or collection they have in their home, for fear of theft. Sadly nothing new - even the model magazines of the 50's would run ads from a club or individual who had a valuable locomotive stolen during an open house - people were that brazen to just reach over and pick up something and stuff it under their coat, and walk right out. The sad thing is, the thieves were obviously familiar with the hobby because they would take specifically valuable pieces, not just randomly grab stuff.With a collection like that, there have to be MANY pieces that are one of a kind, or extremely rare. Another similar rarely seen collection like that was owned by an Italian who was in part behind the Rivarossi company. There was an article in an older magazine I have where the author was given a rare chance to meet the guy and visit his home, which contained an astounding collection of model railroad history from old cast iron pull toys to the most up to date handcrafted scale models.I myself am somewhat torn. I don't want to build up a large layout that is only seen by me, but I'm not sure about allowing just anyone into my house to see it, either. I do have the benefit of a door to the outside which opens directly into my basement, so no one would ever be in the other parts of my home. There are a large number of modelers who open their layouts during November, a huge list is generated with schedules and directions and basically you just go to the address on one of the days and times they have listed and you can tour that person's layout. I would guess though, that for every name on the list hosting an open house, there is at least one other, maybe two, who do not want any public notice.

content: Hi thereI'm new here and just as good as average beginner in electronics. I'm a old programmer and done a lot of heavy stuff in that department. I know simple terms and understand somehow some basic concepts as transistors, relays, resistors, diode, capacitors and can I have made some simple logic gate's when I was younger.The problem I'm facing now is I think kind of way to simple for you guys. I have a simple circuit for motorcycle, to show what gear it is in, Gear Indicator. Ok. I bought this very cheap from China. Every thing works as it should on the bench.. that is, until I test it in the bike.The neutral wire was supposed to return 0v when in neutral (no gear), otherwise it returns 12v (for every other gear setting's) which is the main voltage on the bike. The problem is, the neutral sensor is is not returning 0v when the bike is in neutral. It's returning 0.5 something volts which is not low enough for the gear indicator circuit to trigger neutral. I haven't bother to contact the manufacturer but I did some simple resistors to ground check and with I think with 10ohm resistor I got 0.22V (if I remember right) and that did trigger the gear indicator properly.. but of cause that kind of resistor alows withdraw much power and not usable when the bike is running in gears and the signal is 12V.So.. I must add some extremely simple way to kind of "mask" all low voltage to zero. Let's say at least all voltage below 1V masked down to as close to 0V (0.1-0.2V seems to be enough)Any idea how to do that without drawing current when signal is 12V?

Its a real art to make some glass tubes, craft some metal shapes, wind wires, etc, and then do stuff with them. They can be very tough, working under a wide range of settings. In the 'post-Apocalypse' you will hope you remember this.I only started caring about them these last few months, being fascinated in the history and workings of radio and TVmaking a miniature vacuum tube triode
