content: I tried searching the forum but I'm only getting results of people building their own charging circuits. I'm looking for a commercial charger for NiMH AAs (eg Eneloops) and 14500 & 16850 LiOn/LiPo. I would like something reasonably safe that won't abuse the batteries, the unit I want to replace was just a capacitor and diode bridge. A reliable source for protected 14500 and 16850s would also be nice

content: Original site:http://www.saikatbiswas.com/web/Projects/Livecell.htmI was surfing around and ran across what seems to be a rather fascinating idea. Similar to the shake-to-charge flashlights, it operates on an inductive charger built into the cell. I admit I am not educated enough to estimate what kind of charges such a small inductive generator could achieve, but the concept doesn't seemtoo far fetchedto me.Is this just another batteriser? Or do you think there might be something to this?

content: The Li ion cell depicted is shown to have a 2500mAh capacity. AA is 14500 and a li ion of similar size is about 700mAh about 2.6Wh. Unless that "2500mAh" is at 1.2V dropped by a DC-DC converter which will be 3Wh which is still way over rated for the size shown.I'm not too sure on how much power you can extract from shaking but I'm pretty sure it will take a very long time for that to go from empty to full.There are other gut feels I'm getting (also the lack of technical details - probably a very early idea stage only) that isn't right but these are what I thought of first.

content: Given that the renderings show that maybe 2/5 of a AA battery is actually used for the energy storage, it might be possible to fit ~300mAh at 3.7V, so somewhere around 800-900mAh at 1.2V MAX - definitely nowhere close to 2500.

content: Is there a place I could source 0.3mm or maybe 0.4mm PetG sheet?Reason:I have been using a rectangular piece (10cm x 7cm) of 0.5mm polystyrene sheet to hold small ceramic tiles, arranged with 6 "wings" so there is one tile glued on each wing.The polystyrene holder with its 6 wings is semi-flexible just as I want it, however, over time, it develops stress marks and eventually parts of it snap cleanly off.While looking into other materials as candidates for my holder, I used a 0.5mm PetG sheet that glued on the ceramic tiles perfectly the strongest bond seen so far. But the PetG material at 0.5mm was much stiffer than the polystyrene at 0.5mm, and that would not do.I need something flexible, just like the 0.5mm polystyrene, maybe even a bit more flexible, but it must be strong and not crack. I think PetG at 0.3mm might do the trick.I do not flex it a lot, maybe 30 degrees total across opposite sides and always to the same direction - imagine a 10cm x 7xm rectangular piece placed over a size 5 football, but even so the polystyrene holder has cracked over 6 months of daily use.

Currently using one, sold as a 9W unit, as an uplighter, and the LED just reaches 50C, while in the original case it was running over 90C.

My hot air station is set back a bit, but I have a cutout in the bench top for the hot air hose to drop through. No way I'm splaying that mess over the top of my bench, no less in front of my computer monitor.You might consider putting those items underneath the bench, up front. Not on top at the back. Hot air, in particular, often have a very short hose/cord, and the holder is sometimes designed for the hose to hang off the front of a bench.

content: I bought this US$2.99 (free shipping) USB power bank to use with some laptop-harvested 18650 cells. It seems to charge up a cell OK, but I found it didn't source current through the USB A port. A quick tear-down followed, and I came across this funny 0R bodge angled between a pads marked for a cap and for a 6-pin IC.

content: I tested the power bank by connecting it to my Agilent 66332A set for 0V and 100mA. This Agilent DC source can also sink current, acting as a programmable load. The power bank immediately went to 0V output. Another power bank of a similar design, but with a nonremovable Li-ion cell inside, works OK in this test and supplies 5.1V and 100mA to the 66332A.

content: When I applied the same 100mA test method to a third power bank (also with a non-removable 18650 cell), it behaved like the non-functioning removable cell unit. This got me doubting my test method, so I attached a scope across the output. In the case of the working unit, the output voltage drops down to about 2V before the boost converter gets going and outputs 5.1V. For the removable cell unit, the output voltage drops down similarly, but the boost converter fails to start up and the output goes right down to zero.Thinking that the load turn on may be too fast, I inserted a 24 ohm resistor (lowest value I had handy) in series with the 66332A DC load. With this resistor in place, all three power banks turn on and supply 100mA just fine.

For me, a front panel for a 2 unit high, half width 19" box (i.e. 8.5x3.5 inches), 2mm thick Al cost 110 EUR+Tax for 3 pieces. There is some base charge in there, so one piece probably would have been 50-60 EUR.If you use their software, you can get the panel price right away, although the software has its drawbacks (it is basically a PCB layout software, Target, modified to handle front panel design). It is the only supplier I am aware of offering color graphics printing on aluminum AND online quotation.The quality of the panels in my case was perfect. I think they quoted 8 business days until shipping, and they used pretty much exactly this time. I can't tell you about the shipping time to the US, I live in Germany, and the company is located there, too (Beta Layout), for me shipping was overnight.

You would need a special tool for every PCB layout with all the holes punches in it. I figure it is maybe cheaper to combine several board layouts into one punching tool (same hole pattern, different copper layout). That would keep the tooling costs lower, but would result in unnecessary holes in every board.

content: Hi ladies and gents... looking at a vacuum desolder station for through-hole boards for the workshop. Not going to get lots of use, but I want something quality for the bench. I've always just used a hand desolder pump, but the budget is there and we are getting busier in the workshop so this should save some time...The two I'm looking at are the Hakko FM204 and the Pace ST75E. The pace is $400NZD more expensive,but it was recommended to me by a colleague... so I'm asking for your opinions on either... or both! Thanks in advance

I don't use it on a regular basis, but it always does the job.I haven't used the Pace unit.The Hakko hand piece is lightweight and ergonomic. It can be used as a pencil grip or with a pistol grip. It has great suction, cleaning up the holes and pads quite well.Sent from my SPH-L720 using Tapatalk

content: Hi!Just in case, you haven't bought anything.I think the Pace is way more ergonomic compared to the Hakko.I have used both Handpieces on different stations than your choice, and the Hakko, in my opinion, is rather strange to handle with this pistol-grip:You have a rather uncomfortable angle if a PCB is lying flat on the desk (you feel like standing up for desoldering) and without the grip (that is how I used it) it feels really strange to hold. The shape is not made for that and the trigger on the bottom-side is not handy at all.The Pace is more comfortable in that respect with it's straight Iron and the big, round grip.What I personally like most are the angled Weller Irons.Just my personal opinion, since I used both several times

content: Hi EEV forumFirst post here, but I've followed the blog for many years now.This isn't going to be a very technical post, so sorry for that. And, to be honest.. It is mostly a rantSo if EEV forum isn't cool with this, I won't be offendedBut we are gonna talk about big consumer-electronics companies approach to software availability for their products.I've noticed an increase of marketing and design wank on consumer support sites. And when you do find the product that you need driver modules for, there aren't any.So my current example is my Samsung Galaxy Alpha.. I know that I can just get Kies software (more like bloatware) and it will find the correct libraries or whatever.. But I need to install this in an offline environment.. So. My life would be much easier if i could just download the drivers manually..But the only thing the support sites make available, are manuals. Despite the site layout being different in each region.And I've seen this before. HP, Sony, Samsung, Asus (only 1 or 2 times) and Toshiba have done it in the past. And it's rare for this to be a common thing in a product line, but my impression is that it is on the rise.I feel forced to download a lot of software that I do not need. And I feel neglected when the resources that are necessary for my device to interface with my PC only can be obtained through other software.Intel is a prime example of a company doing it right. They have a ton of utilities and drivers that are free to download from the website. Many of them are not necessary. Some of them are common drivers.But it is all there. At the product support page. All of it. Brilliant!I just find this "proprietary" driver solution to be a worrisome trend. I have actually thrown out a phone because of this.I had a rooted phone. Windows downloaded Kies and drivers needed, but Kies would return errors, and the drivers would crash on those errors.Later I got it working on a old laptop with some legacy Samsung drivers already on it. But I had already bought a new phone..I know that this isn't an engineering problem. And I know that the resources I need are probably available, somewhere.. But it is still aggravating to know what you need, but the company haven't made a decent support/software standard.I have no idea if any of you have bumped in to this particular issue, but I would love to get your perspective on this.

Calcium Lead Acid Battery and Vibrations - Page 1

timestamp: November 27, 2015, 08:22:04 am
content: Dear all,Recently I've encountered a strange phenomena with the gel Calcium Lead Acid battery.I did some shock/vibration testing with our device powered by YUASA NP7-12 battery. The highest amplitude applied to the device was around 40G. Battery was full and it wasn't discharged while testing.When the battery returned to the company I found out that her performance on the peak load (impulse load) has decreased. In a way that when it's connected on a 6ohm wire resistor the load current requires about 2 seconds to reach about 2 amps. The current starts with 0.5A, after one sec. is about 1.2A and after 2 sec. is about 2A. If I repeat the test right after last one the current is 1.8A on start and rises to about 2A. If the battery rests for a while it again has a load current lag. When I used a non-shocked battery of the same type load current was instantaneous at about 2A. Voltage on the battery terminals of both batteries is 12.8V unloaded.I did look for some information on Google but had no luck. I found here that a special type of batteries (such as AGM) was invented for the vibration rich environment.Can You help me on demystifying this situation? Is it really the vibrations that damaged the battery impulse performance? Are there any scientific explanations?Thx!

content: As no one else has any ideas I'll put my two pennies worth.I believe that the Yuasa NP series have a glass fibre sponge that holds the electrolyte rather than a gel. Possibly the vibration shook the electrolyte out of the glass fibre or posssibly the electrode plating has fallen off.Yuasa may have an answer. Their technical back up was pretty good a couple of decades ago when I last used it.

content: iOS supposedly supports lots of external GPS receivers. (Google is your friend.) Not sure where you got the idea you'd have to jailbreak.As for why they don't put in a GPS receiver: probably cost and battery life. In the iPhones (and iPads with cellular, since they use the same cellular chips), the GPS receiver is part of the cellular chipset (since it's required by law for E911 compliance). So it's "free" in the phones, but not in the iPods. As for battery life, on iPhones and cellular iPads, iOS does not do "pure" GPS geolocation because that uses tons of power. Instead, it always uses A-GPS (Assisted GPS) which uses the cellular towers (and wifi) to get a general fix, then uses GPS to get the exact fix. This saves lots of power, apparently.

Having just run out of Tech Spray 1803-5F, I bought a roll of the Philips to try.It's important to note that the Tech Spray seemed unusable when I first got it. That turned out to be the Aoyue soldering iron, since replaced with a used JBC. Both the Tech Spray and the Philips work remarkably well, particularly with a big 2245-211 high thermal efficiency 3mm chisel tip.Jameco also has some .05-inch Philips for $10 for 25 feet.This is the first time I've ordered from Jameco in years. I'll have to pay more attention to them.
