um excuse me posted:Oscilloscopes. Something I last used about a decade ago with equipment from the 80s or 90s. I remember the one I had was a Tektronox 2 MHz analog. I used to use it with a signal generator and a logic tester. Is the market pretty much the same? I saw there are some USB based ones, are those useful? What about the multimeter ones? Are ones under $100 trash? Are there combination scope/signal generator/logic testers out there? I'm super out of touch but want to be able to test ICs. Testing ICs is literally my job. Get the Rigol 1054Z as nmfree suggested. We use them when writing test programs for the big ATE testers, and even occasionally during regular production testing to verify device functionality. One of our test engineers has the hacked firmware on his personal scope, but I haven't really encountered anything that the stock configuration can't handle. If you want to screw around with oscilloscope music though - you have to have an analog scope. We have a few old Tektronics units from the 60s and 70s around too and when we really want to blow people's minds - I just put Jerobeam Fenderson's music though the scope.

nmfree posted:Short answer: Rigol 1054 Yup. The 1054z is an amazing scope for the money, and is easily upgraded (http://www.gotroot.ca/rigol/) to 100Mhz if you need it. The deep memory is super useful, and it's well-regarded as the best beginner's scope.

Now that I'm at an actual computer, I'll follow up the Rigol 1054 talk with a link to the Saelig Discount Thread on the EEVBlog forums; I don't know what the exact discount they're offering is, but it's probably going to be the cheapest offer on the Internet.

Thoughts on corded vs cordless grinders? Obviously if you're often on job sites where running power is a pain, the use case is obvious, but is there any use case your average backyard tinkerer might run into where a corded grinder sucks to use? I've been borrowing my buddy's corded grinder enough that I want to buy my own, but if I spend $50 on a corded grinder only to run into a job in the next couple years that makes me wish I'd spent the extra $100 or so on a cordless grinder I'm going to be irritated.

I love my M18 grinder, but you need to be stealing a *lot* of bikes to justify one over the mid-range HF corded jobby.

I have a $15 closeout special Skil 4 1/2" grinder, and it's ground hundreds of feet of steel, aluminium, concrete, and sometimes wood and plastic over the last 8 years, it's gotten to the point where I'm using it for 10 foot long diamond blade concrete cuts with water lubrication to try and kill the drat thing because I can afford nice tools now and want a better grinder, but I can't justify it because this stupid POS will cut anything. Also, grinders are one of the few tools left that will outstrip your charging capacity during use, if you're not a coneseur of big batteries and multiple charging stations.

IOwnCalculus posted:My mid grade HF grinder is loving scary powerful. Come use my 9" Metabo. 15A of angry German grinding action... Cordless grinders are great for little stuff, remote stuff, or for using a cutoff wheel in dicey spots (they don't have the power to do nearly the damage a corded grinder does). My Makita is great, but there's a reason I've got 4 corded grinders. Aside from being a tool hoarder.

I buy tools for the fab team at work and splashed out on a couple of DeWalt DCG405FN-XJ, they're plenty powerful, 5ah batteries last long enough and they get into tight spots easily, but they're £240 each bare tool Vs ~£140 for the really good corded ones. For home use I spend about £25 personally.

peepsalot posted:Aren't there technically some (probably really high end) digital scopes that sort of simulate the fade/persistence of a CRT scope? I want to say I vaguely remember a youtube video, probably EEVblog, demonstrating something to that effect. You can get a fairly clean picture even on a 1054Z - https://www.youtube.com/watch?v=4WcJw_uI6l8 and here's a higher end Rohde & Schwarz scope: https://www.youtube.com/watch?v=E2tex3IlE44 But the digital scopes will be limited by the refresh rate of its LCD. The real magic of using an analog scope is the basically unlimited smooth motion that doesn't even look real right in front of you. If fact, youtube videos of an analog scope also don't capture the smoothness because of the digital cameras used to video them have no hope of keeping up. 0toShifty fucked around with this message at 15:58 on Jul 12, 2019 |

Even name brand corded grinders are cheap enough that you can dedicate one to each disc so you don't have to waste a bunch of time switching between cutting/grinding/flap discs all the loving time. I guess you can do that with cordless grinders too but even my tool lust won't let me justify spending like $700 on angle grinders.

I remember someone posting about a tool for working on sinks that can reach far up into hard to reach spots to turn nuts. Like an open ended wrench on a long extension. Anyone know what I'm talking about? Can I get a link? Got a small leak I'd like to tackle, but it's too much of a PITA to actually work on for me to do it.

No, they’re open end wrenches, since faucet studs are often arbitrarily long to accommodate really thick counters, and almost invariably loving-impossible to get to. You can also sometimes get a crows-foot socket on them, but not always, and almost no one has crows feet in the bigger sizes.

So basically the alternative is to shut the cutoff valves (yee haw if they are the cheapie oval type), undo the sink from below and remove the whole assembly.

Assuming the gave you enough extra flex hose to get it out of the counter, yes. (They didn’t.)

Yeah I've used those sink bolt wrenches without any issues too. One of the few single-tasker tools that excel at exactly what they were meant to do. Throw some pillows under your back if you're going to be under the sink for a while, holy hell is it a back breaker to lay under a sink.

Anyone know a physical store where I can get an M16x1.5 die? I need to recut some threads on a power steering flare nut because the ones that came on the new hardline won't thread. I can only assume that they were cut by a syphalitic chimp because it's the same size and pitch as the old one, but it will not go on

I have the 932/6 set that's on sale. They're literally called chisel drivers. I've literally used them as such before to great effect and no damage to the tools. They warranty claim ones that do. I've heard amazing things about the 334/6 laser etched drivers as well. Holy moly what makes an 11 piece ratcheting combination wrench set $220 on sale?

https://www.amazon.com/HAUTMEC-Telescoping-Capacity-Telescopic-10-inch/dp/B072QD5D3F/ I'd recommend a telescoping tap wrench as the adjustable length helps get the handle where you can turn it without hitting anything.
