content: https://www.facebook.com/DalbaniGlobal/?rf=146981031997243http://dalbaniservices.com/home.htmlThese folks sell obsolete parts, sometimes NOS, sometimes pulls. They have a large number of eBay listings, which seems to be their primary storefront?Anyone here got a comment to share? Thanks.

content: I've been buying parts from them for at least 20 years. Years ago at least they sold more than just chips, they had general electronics parts, supplies, test gear, etc. I mostly bought stereo amp chips/modules because a lot of folks don't seem to understand stereos generally don't like their outputs shorted together. I got out of doing electronics side work several years ago so I haven't had any dealings with them for a bit. Never had any issues with their parts, even the pulls worked fine. Only complaint really is shipping always takes forever coming out of Florida for some reason, but that's not Dalbani's fault.

Prices and quality were good, but who knows what has happened over time. I wonder if it's owned by the same people? If it is the same owners, good for them to still be around!

He did a video recently showing a space across the road that was really small, I think he mentioned it was the size of the front room of his current place. The asking price for that one was $10k.Edit: He does mention at the end that there is a shortage of space and stupid tax laws that practically incentivizes people not to rent out space. Then he says even if he spent 3x as much for a similar space for 15k-20k it would be the same size as the current one. So I'm guessing it's somewhere below 10k he's paying for the current one.

I can run basically whatever custom code I want on the host side, but I would prefer it to be simple and straightforward, that would be trivial to keep working after upgrading the kernel.

content: I am designing a range of products that requires 9V DC from a wall adapter.The circuit will handle up to 10.5V absolute max before anything is damaged.Since power is supplied by the user from a normal DC jack i need protection from both- Over voltage (someone will probably try a 12V adapter or an unregulated 9V adapter etc)- Reverse polarity adapters (center neg vs center positive)Does anyone have a good circuit that does both of these together?It would be nice if it was possible with a few mods to a normal p-fet reverse polarity protection circuit.Ideally without any extra ICs (compactor etc)The over voltage protection doesn't need to be super robust, if at 20+ Volts the product still blows up that would be fine.The protection is mainly to stop damage from 12V adapters or peaks from unregulated adapters.

Is it something that would actually work? I've attached the script here. It's safe to open/read but I suggest not executing it as I have no idea what it does.Edit:Attachment removed to prevent misuse.

Step one would obviously be getting the script onto the vulnerable machine, then executing it. Then what? Does the machine join a particular IRC server/channel waiting for commands?

content: It connects to an IRC server and listens for commands sent to it over IRC as a private message (PRIVMSG), and response via private message.It joins the channel "#y" by default.You can see the command's being parsed in the "parse" subroutine, the if block matching against PRIVMSG matches the main commands, the remainder appear at casual inspection to be for handling nick setting/changes and the initial join.I don't know what titi and goni are about, I expect they were for some function which is not present in this script.

author: Ampera
author_rank: Super Contributor
timestamp: May 10, 2019, 06:55:36 pm
content: Because of the concepts of economies of scale.Situations where data permanency is absolutely required regardless of external influences like cosmic rays aren't too common, and don't usually require massive hunks of storage. Since you can have read only flash memory by just not writing to it, it's cheaper to just make flash memory and use it as a ROM/PROM instead.You then have things like mask ROM, which while tooling is expensive, if you're making thousands of copies of whatever it is you're making, will end up being way cheaper than NVRAM or PROMs.

content: When flash cells get stuck, I don't think they necessarily get stuck in the state you wish, rather they have failed and may be stuck in a random or invalid state.The old bipolar PROMs used nichrome fuses that were physically burned out to program the device. This architecture could not be scaled up to capacities anywhere near useful in modern devices. Mask ROMs were another technique which was widely used at least up into the 90s but there are few applications that require such permanent semiconductor storage.

I think it runs on 400Hz 115VAC so that might be the hardest part of getting it to work. I was watching another youtube video where a guy was trying to make some sort of avionics work and he kept blowing up the parts and I remember writing in the comments that it was 400Hz and he had no idea that you can't use mains 50hz on it. On the peto tubes on the side of air planes say 400hz on them so that was the only way I know it was 400. I'm guessing it's 400hz so they can make things lighter on the plane, back before everything was SMPS.Maybe if this is above dave pay grade he could do a collaboration with someone who could get that running. I know a lot of people were waiting for another episode after the tear down.

Shapeways,dirty PCBs, your hackerspace, or others.For something like the dirty PCBs SLA, they can basically print anything. But if its from a hackerspace (FDM), there are some limitations on to how you can design the part. If its a simple design I wouldn't worry about that right now though, it will probably be fine.

content: According to the BBC news report, Peter Mayhew's casting as Chewbacca was something of a happy accident. Dave Prowse was apparently originally down to play him, but he wanted to play Darth Vader instead. Peter was cast fairly late, based on his stature, before going on to make the character well and truly his own.It makes me wonder if, had the original casting stood, Chewie might have ended up with a Cornish accent? (Prowse was dubbed as Vader - "Luke, oye am yurr farther!")

Problem is I have horrible eye sight, as you can see in the back ground, I rely on making the text bigger ctrl+ style. Can you somehow zoom or did I just waste 39.99$? I originally downloaded this on a netbook but would run an external monitor so this was never a problem. Stupid how small this is. Amazing thing is you can actually make out the text if you hold a magnifying glass to the screen. I had no idea my screen was this good, honestly I didn't realize it was 4k until after I bought it a week later. I could always just listen to the weird acid jazz music, but I want to crash kerbels!

There are too many games out there that don't play well on higher resolution displays and the developers just don't seem to care all that much. I use a 42" 1080 TV as a monitor and from 7 ft. away the in game text in most games is nearly illegible.

Some time ago (the video may even have been posted by you) I remember seeing a YouTube video about the last TV repair shop in a city closing down as a) there were no CRT TV sets around anymore and b) flat screen sets either run forever or get thrown away when they break as replacements are so cheap.Two years after he bought it the power supply caps failed on my neighbors Samsung TV. He was going to buy a new one (300 Euro) but I repaired it with 30 Euro of components from a local electronics shop. The throw-away society has killed off the repair shops and only the enthusiasts like us are left.

content: Louis Rossmann and others have proven there is a growing demand for electronics repair shops. The old ones have faded into obscurity, due to the fact they were all focused on older technology. Some did try to adapt, but the modern paradigm has everybody convinced you can't fix anything, so these businesses had the skills, but the customers dried up. They just didn't know any better and the shops/techs weren't used to doing any kind of marketing.The old repair guys didn't advertise because they didn't need to. Like an auto garage, they were always backlogged. But these days, people need to be told that they have options to repair things.I think there's demand there, but half the problem is the consumer isn't aware of it.The TV fix is perfect example. Most of those failures are the usual. And people are cheap...they'll always go with the bottom line, but how many people know that there couple year old TV was just built with cheap parts and a quick refurb will make things like new?They don't know, as also mentioned in the post and example above.The key is to connect the techs with the general public. They need to know that their devices are repairable and there are people qualified to do it. A part of the problem is people like Louis and the like are preaching to the choir. They're trying, but it probably needs to be the whole tech community teaching the wider public better choices.

Most impressed with the product for that price. 120Watt iron, digital temp control. All works nicely and even the iron soft grip is good quality as is the stand. Only slight down is length of cable and slightly hard silicone (?) outer. Apart from that, I don't know why I struggled on with old falky Weller stations for so long! Also now even more convinced of overpricing of the brand names.

But the iron looks like a Weller design from the heater and tips, and all indications are that the station is 90W according to Bakon, which could be overstated.The BK2000A (90W) I found on gearbest was $156 and ebay was $200 and considering it comes with all the idiosyncrasies of a Chinese home brand station (questionable specs, safety, reliability, warranty) combined with the older style iron, not great value at all.
