content: instead of using a bix use an insulin syringe. they are very skinny and long and are compatible with luer-lock needles. then simply get flux dispenser needles as pickups. or get one of those cheap chinese vacpen clones that come with little suction cups. those will fit luerlock tips as well.

content: If you have a couple of wire harnesses to make, I think it would be nice to have some pre-crimped wires for a standard d-sub connector (male or female) that you could just pop in. This way you wouldn't have to worry about getting a crimp tool or crimping all the wires. Thoughts?

I never seen something like this.But if you mean something like those connectorshttp://www.winfordeng.com/products/cni25.phpits easy to crimp those with small bench-top vices that i think many of us have or can buy for like 5 bucks.IMO bad product!

content: Quote from: craigfoo on September 02, 2013, 04:13:56 pmNever heard of this option from sales sources. Assembly houses have done partial assembly jobs before. If you are going down this route, it would make more sense to get the cables completely assembled by a cable fabrication house. We have always made cables under 50pin and under 50' in-house, so I don't know what the cost margin would be.Since you just mentioned a std DB connector you do have the option of solder cup or ribbon clamp instead of crimp pin.

content: Way more reliable than soldering, and can be easily inspected before potting. Remember this was done when PCB manufacture could not do multilayer, through hole vias or thin traces. They went with what was reliable, could be made with good QC and which would survive high vibration and temperature extremes. The common PCB material then was SRBP, and the GRP boards did have a terrible problem with copper peeling.

content: It is not a LM317 replacement. The LM317 references its reference voltage to Vout. Which allows for some of the trickery which makes the LM317 popular. The KA278RA05 references to GND. 3-pin adjustable vs. 4-pin adjustable. As an LDO it is a bit better in some circumstances than some plain 78xx or a normal adjustable linear regulator. But besides that, and unless there is something especially good in the performance (I didn't check the datasheet), I don't see much advantage over normal fixed or adjustable LDOs. Perhaps if you need to simplify a BOM where you need a couple of 5V and a couple of unusual voltage rails. Or when you want to simplify inventory a bit.And when it comes to design with it then the existing internal resistive divider makes it a bit more annoying to calculate the values for the additional external resistive divider. Still OK if you need a fixed output voltage. But it gets really annoying if you want to make a user-adjustable "lab" power supply, since you won't get a linear adjustment.
AA Battery cell phone chargers - Page 1

content: A local store had some of those on sale for $2.42 each with battery so I bought 3 (one for me, my wife and mom)I figured it was just a joule thief and I'm pretty sure I'm right. The device itself appears to be a AA battery based flashlight housing made out of Aluminum. The end is just a end for a small flashlight with a 2.5mm 2 pin jack sticking out.It also has about 10 interchangeable tips for different phones.The tiny little board is about the size of a penny and has on the bottom what appears to be 2 transistors, a small capacitor and a resistor. One the top it has the jack, a larger cap, an LED, a big diode, and a coil. It is silk screened HF-05AJ.The box says it can supply 400mA but I've managed to plug my HTC Droid DNA (HTC Butterfly or Deluxe for those outside the US) and it says "AC Charging" on my battery widget which would make it seem it was drawing a full amp. But after a few minutes of charging, a warning comes up saying that the phone won't charge as fast and please use the genuine charger.Also it did successfully boot my Raspberry Pi from just the AA battery inside. Overall I'm pleased. Now the coolest hack I think would be to add a USB input into this device so that it can charge via USB.The only down side is the 2.5mm jack is very touchy. If you move the cable the LED tends to shut off and stops charging.Now that I think about it, this device is small enough that you could potentially squeeze it inside a car charger. That would be cool. Just unplug it and take it with you and keep charging.

content: Leave it! The ones with the old blue Tektronix logo are the oldest. These scopes have leaky caps and the electrolite eats away tracks and vias (for some reason Tektronix choose not to put solder resist over the vias on the 6 layer boards) causing the failures on the screen. If you want a scope from the TDS500, 600 (check for peak detect first!) or 700 series make sure its from 1995 or later. Every now end then a good bargain turns up.

I thought some people might find the theory sections of that manual interesting, even if they don't have one of these slotted lines. So I've scanned it.Here's the complete manual:http://everist.org/archives/scans/GRC/900-LB_slotted_line/GR_900-LB.jpgI should warn you. It's not a pdf, it's a RARbook, which is a RAR archive attached to a jpg cover image.You'll need WinRAR to open the archive, and you view the thing with a web browser.It's about 80 pages; the downloadable file is 26 MB. Yes, it pretends to be a small jpg, but it isn't.You should right-click save-as on that link, otherwise you'll be looking at the small jpg with nothing else to do for a while as the rest of the 26MB file loads.Also I'll be tweaking it a bit still, and adding some other related GRC stuff. So don't get all public spirited and go sending it to the HP/GRC archive sites yet. I'll do that when it's ready.

content: So I recently downloaded Tapatalk 4 on my Acer Iconia Tab A110. It's specs are almost identical to the Nexus 7 for those who know that one better. Basically it's got incredible graphics power, and a great CPU. It's always worked great for me and I've never had any problems with it (except dropping it all the time -- but that's because I'm a klutz. On a side note, if YOU are a klutz and you're constantly breaking your iPhone/iPad screen, seriously consider this tablet -- it's been through HELL and back and it still works fine!)Anyway, I downloaded it to read this forum, and also XDA-Developers. At first it seemed to be working great -- I don't know what other people's experiences are with it, or if it's just my tablet that's doing this. But whenever I'm reading a thread, and I get to a post that has more than two or three pictures/YouTube videos/other embedded media, after loading the first two it suddenly blanks out the whole post and usually one or two posts after it. This has gotten EXTREMELY frustrating because typically the posts that have all the photos and videos are either the original post, or a pertinent update/response, and I haven't been able to find a way around this glitch. I sent a report to the developers and haven't gotten a response.Just wondering -- has anyone else experienced this glitch, or any other problems with Tapatalk 4? Is it possible for me to find an .apk of Tapatalk 2? I've heard good things about it and a lot of people were hesitant to upgrade. Honestly -- the app feels kind of thrown-together. Often it will 'crash' back to it's main page when trying to open a thread. I'm really not sure if this is my device, but I really doubt it -- it's a quad-core CPU, and man, apps that are extremely graphics-intensive run without a hitch, so I kinda have a feeling it's their code.I'm really curious to hear what people have to say. Are there better alternatives?

Anyone that does that gets a rightfully deserved lesson on safe computing right there on the spot. The list of people that have received a good shaming includes a fair number that really should have known better.The conversation usually goes something like this:A-I got an Email from UPS saying there was a problem with some shipment and I can't open the attachment. It doesn't do anything. I tried a bunch of times.Me-Did you send anything through UPS?A-No.Me-Are you expecting something from UPS?A-No.Me-What happens when you check the tracking number on UPS.com?A-It said it was invalid.Me-::Facepalm::

They are often really unreliable for email, and it's difficult to break through the language barrier by email or by phone.I Googled phone translation services, but there are tons and many of them want to get you into a contract.I am wondering if there is a company where you call them, give them a credit card and then they call the other party, and they act as a translator... then you just get billed by the minute for each use. I don't use it enough to want any sort of commitment, just a reasonable pay-as-you-go situation.I know such services exist (tons of Google hits), but can anyone recommend a simple and easy to use one?I say this sitting at my office at 10pm trying to navigate a Taiwanese supplier's phone system that says "Press 9 for English" and then launches into Chinese when you press 9... and who hasn't responded to emails and who has a shipment of pretty critical parts I need ASAP to fill an order!

content: Hi guys. I just received a new Rigol S.A. The minimum Resolution Bandwidth is supposed to be 100Hz. On Rigol's website there's a video for the '815 which shows a screen shot where the RBW is plainly 10 Hz.The shipping carton for my machine has a sticker on it indicating the options for which this machine is licenced. One of the options is "RBW10Hz". See the attached pic.10 Hz RBW is standard on one of Rigol's more expensive machines, but not on the'815.In the manual, the acknowledged options are (0001) DSA800-TG, (0002) DSA800-AMK, (0004) DSA800-EMI and (0005) DSA800-VSWR. What happened to the middle option (0003)? Is it 10Hz RBW?Could this be another performance upgrade that's there in firmware waiting to be hacked?Ken, VE3FIT

So the longevity remark is about having better write-endurance than flash memory.Edit: actually it seems like it is volatile, so not really a replacement for flash memory, but more like low-power DRAM that doesn't need to be refreshed, but loses its contents when power is lost.
