content: I recently placed an order with Jameco for various things, one of them being 556 timers. I was fascinated by the fact these were made by Intersil, stamped "INDIA", and had a date code from 1980.How do components lay around for FORTY years before being sold by an established electronics seller? Unless Jameco bought these back in the early 80s and has sat on them for this long. Even if that's the case, this brings up another question: How can the purchasing department overproject sales this badly if that's what occurred? Maybe they got a good deal, but then there's opportunity cost.More than anything I'm fascinated by this. This isn't even an obsolete part, except the manufacturer.

But then there's hardly any cards to be found anywhere, they sold out in no time.

hantek dso8060 dead? possible fix? - Page 1

timestamp: December 23, 2017, 06:48:38 pm
content: Hi there,This is my first post and i want to say "Hello" to everyone, before i start to post my problem....I just bought a "dead" hantek dso 8060 oscilloscope which is one of the first models i guess.... since it has a serial number around "400"the owner said it was stored for a long time, and when he tried to power it up, nothing happens.I received the unit (without battery) and first thing i did, i plugged it the ac adapter and i gave it a shot.SURPRISE the unit powered on, i heard some relay clicking, the logo showed up, it went fine for a few minutes.I didn't have any probe around to plug in and test.THEN when i was pressing f1, f2, f3, f4, some white "balloons" appeared above each "f" key, but they were empty.I tried to change the resolution, then the screen started to look awkward or a little messy, like a failing video card (some white and black pixels)Then i turned the unit off, and it never went on again.If i press the power key for 1-3 seconds, when i release it, it beeps, i can see some "flicker" on the lcd, then after aprox 10seconds, i can hear a little click (again in the buzzer) which signals the off state...I tried to keep pressed "ok / enter" key for 2 seconds, then while i keep it pressed, i press in sequence f1, f2, f3, f4 and each key press comes back with a "beep" but that's allnothing happens...I'm not an engineer, i'm a weekend hobbyist in electronics... so for me without a schematic i can't understand a thing.I took it apart inspected the board and components but everything looks fine.The board is very dirty because of uncleared flux, in many areas, but i assume it's normal since i saw this mess on other boars while i google for schematics or fixes.Things i did until now:i changed the crystal y4 (i tried 3 because i had them on a pc motherboard, yes the same 32.768khz) - no luckI put in some 7.5-8v battery li-po 5ah - no luckchanged 2 x 100uf 16v caps - no luckAnyone have any idea? Any luck to have a schematic? at least for the power section.Thanks!

Very draconian and the person standing in the 10 items or less will do nothing most of the time, especially with a virus (buy more go less). But realistically the person there should ask you to leave the isle and go to another one rather then charge you more, its like getting hit with a land mine when you get the bill.

content: Hello friends.I have for a long time been fascinated with IC design, specially on the analogue side. However I have zero design experience.Basically I started out as a mathematician. I have a bachelors in mathematics. Later I pursued a master of science in microelectronics and I have been accepted into a PhD in the UK in compound semiconductor manufacturing to start in 2021. It's fully funded plus a small salary of £1200 per month which isn't much.BUT......I would really like to work in the industry and find a graduate/beginner level position into chip design. I am 34 years old and have no experience like I said. I do have knowedge of the theory, specially the physics side of it. My knowledge is all theoretical.Do I have a chance of making into this field? Are there positions for people with no experience at my age?What should I do? Should I just bury myself with textbooks and study them as much as I can and hope to find a lucky position?I just don't know what to do. I prefer analogue because I don't think of Verilog as electronics. I don't want to write code for electronics. I want to be with real electronics and deal with real signals and devices.I also very interested in device physics. I would love to be able to fully master device physics and perhaps process engineering.Should I just pursue the PhD and see where it leads? Or should I focus on textbooks and try and find a job in this area?Best wishesPaul

content: You seem to be in the UK. If you want to work there in analogue semiconductor design, there are limited opportunities. If you look globally, good analogue designers are in demand, because most graduates target digital design and leave a shortfall of people with analogue skills. If you can network with people in other countries during your PhD, you can probably find a way to connect with people looking for people like you, and build yourself a pathway to a career.

I very much appreciate the map and navigation app and will happily share my movement with them and if others do the same google can tell me in return the fastest route to get to my location. Yes they do sell this as aggregated information. I know someone with a BMW electric car and he tells me that the navigation data to the car and traffic information comes from google and is very good to the point that when the queue in front of him moves it shows up on the map instantly but he has a subscription to that with the car. I don't get such detail but what I do get is useful enough for free. It's not like they are telling commercial customers who is in the car in front just that there is a car(s) in front of them.

Looks like in his Facebook posting he used the Eevee renderer for some of the pictures, which is nice for realtime raytracing while editing, but with the Cycles renderer it looks a lot better. I also added an area light above for more natural global illumination. My graphics card has not enough memory to render it with CUDA, but after 6 minutes heating up my CPU I got this:I really like the BNC connectors and probe, and all the knobs and buttons, looks very realistic.He has many other technical models, seehere.What other good 3D electronics related models are out there?

content: The cable is fairly cheap looking, but its very hard to find. You can make your own but I looked into that before and the cost of parts alone to make a serial-USB converter is 1/3 the price of the cable.The cable is rarely sold separately by even cheapo DMM makers, so if you lose it, it can be a pain to replace. I looked into modding a Uni-T cable, but alas the cost of the cable is already $20 and no guarantee my mod will work. Then even if it did, it will look and fit ugly!http://www.ebay.com/itm/UNI-T-UT-D04-USB-INFRARED-INTERFACE-CABLE-UT71-UT81B-/320841222443?pt=LH_DefaultDomain_0&hash=item4ab3a0892bSo in the end, the $31 for the real deal is worth it, as one of the benefits of this DMM is its serial connection which the Fluke 87V does not have.

content: Those switches showed up in SYSTRON DONNER mil spec products, at least back in 1970's.The company manufactured FIRE DETECTION systems both for aircraft and for military ground transport.The interesting thing, there in the SD SAFETY SYSTEMS division, the fire / overheat sensing is done by running a metal tube, (around your engine housing).That tube for one thing, was filled with H2 gas (OR... was it Helium, cannot remember.)So, you get a positive snap of a pressure switch, upon engine overheat. Plus, you've got another pressure switch, just for monitoring the integrity, for leak detection.And, finally, for your basic engine FIRE outbreak: a moly-wound wire (that means MOLYBDINOM ). The moly wire, there in the 8 foot long sensing tube, has been 'cracked' and infused with hydrogen. The high temperatures associated with a flash engine fire will cause extreme pressure rise, as the wire out-gasses.Truly a great and high-end product, I think they also sold systems (again with those vintage lamp display / switches), sold a few systems installed into ground generating units, as well as aviation.The business end, of detector, was a housing containing the pressure switches, and sometimes a 10 k resistor used in fault detection, of the sensor line.Heck, you could even self- test the lamp, right there inside from the front panel. I think it is a 'Press to Test Lamps' push button, included on front face (of the switch / lamp unit.)

Being the highest point, not only are they effective vantage points but, many birds use them to broadcast their calls and songs from. Aerials become the boundary markers for bird territories. As well as frames for some nests. Also with fossil fuels destined for the history books, chimneys will disappear too. By 2060 the urban skyscape may be somewhat different to our avian partners.

I had to call my auto-club (AAA) for a jump a few times in the last few months - this virus lock down is killing car batteries since we hardly moved our cars.While I just replaced our cars' batteries, I'm still considering getting a replacement jumper/booster pac. The replacement battery for the booster pac is hard to find - web search leads to many seller selling deep-cycle batteries with such low max-current that I consider calling it a fitting replacement as a fraudulent claim. The replacement battery market is a mess, so I may need to getting a whole new jumper/booster pac.LiIon based jumper/booster pacs has been around for a few years now, but the pros (from AAA) that came are still using the SLA booster pacs.Given I like to keep the jumper/booster pac in the car, I am a bit concern with the environment it would be in. I've had the LiIon in my Tom-Tom GPS sat on the dashboard for just one hot day and it swelled up to near burst. I've seen a laptop left left in the car one very cold freezing night, and the battery went dead the following morning. I am not sure about keeping a LiIon based jumper/booster in the car.What are your thoughts and opinion?
