content: I need to keep my finger prints off what I'm assembling (FPC cables to panels) and also like to provide some small barrier to hot spitting bits of solder landing on my hands while working under the microscope. Currently I'm wearing desco inspection gloves (non coated) or the coated ones. The coated ones are a lot heavier and harder to do stuff in and the uncoated ones fall to bits really quickly at the finger tips. The uncoated ones feel great though.The Ansell ultra lite hyflex 11-618 feel okay and are much thinner and tougher than the desco gloves, but aren't ESD safe.What do you recommend? If they're stocked by Mouser / Arrow that would be a bonus! Or somewhere that has cheap / fast shipping to Australia. The range at All Spec looks great but shipping looks a bit pricey.

content: I don't know how bad this hot spatter part of the equation is, but I would suggest you take a look at fingercots. Way more comfortable.No one cares about fingerprints on my work, but I wear them sometimes so that the board doesn't stick to and lift/move with my fingers when/where I should contact sticky flux or residue. So I might only wear just a couple on my left hand pinky and ring finger, which contact the boards when I'm using tweezers.So I would use two sizes of cots, one for the pinky, one for the ring finger.

content: I'm in the market for an under-the-bench smoke extractor to replace my tabletop one that's more of a glorified fan.The two models I've found for reasonable prices in Europe are the Quick and Weller in the subject (450-600 euro from eleshop.eu.)I'm leaning towards the Quick because it's cheaper and I don't need the second hose. Is there a reason to consider the Weller or another model though?For example if the Weller is quieter in normal operation that would be a big plus.

content: Make sure spare supplies like filters,etc... are available at a reasonable price. I have the Quick fume extractor and it works just fine, But a set of spare filters costs almost a quarter of the whole unit and most of the time it's not in stock. Of course it depends on your market and where you live.

content: I am lately repairing units which uses 4-6 bga IC and i reball using non-direct heat stencils and hot air afterwards to melt solder balls.That process is a bit time consuming and i am looking ways to bit speed up that process.I was thinking to buy hot plate and after all IC have their solder balls aligned on their pads - use hot plate to re-flow solder for all of them rather than go one-by-one with hot air.Question - someone use this method with hot plate and it might be faster than using hot air and its usable method? Even with low air flow i sometimes manage to move balls off the pads.

content: I have a similar setup and auto-focus works fine. Kind of - if it's just a bit blurred to start with it focuses OK. However, at power-up the camera seems to run to one extreme and then can't figure out how to make the thing focus, so you end up with a small blurred circle. Fix is to switch to manual focus to get it back somewhere in range than carry on as normal, but it can get to be a drag doing that every startup.For the purposes of recording video, should be no problem at all.

content: I am helping with a project that needs a TON of pieces of physical paper scanned.My cheap multi-function printer/scanner is just too slow, can't handle the different size sheets well, and does not gracefully deal with mis-feeds. So I'm looking for something better. A dedicated scanner is fine, but I'm also interested in multi-functions with really good scanners if that's a good option.I figure this is a problem that some industries must have, like lawyers especially. So what can you guys recommend?My basic requirements are:0) Pages sizes aren't wider than letter (8.5in) but may be longer like legal length. Some are smaller like envelope size.1) Good document feeder that handles stacks of pages.2) Able to deal with different size pages in the feeder.3) Quick scan times4) Gracefully recover from jam/mis-feeds.What do you recommend?

84V 10A Li battery charger - Page 1

content: Presumably for an electric bicycle, pic shows this charger. It has just the 220V mains input cable and the charging plug. There is justoneLED indicator, which shines red or green. The entire board is potted inside the diecast heatsink. There are no tappings for cell monitoring.I need to check if it is functional, but alas, have no 20S battery let alone 46Ah.Powering up through 'dim bulb' tester showed the promising pulsing input, stopping after just a few flashes of the bulb. So far so good, I plug it in direct, still good: the little fan jerks (and stops), the LED flashes red and green alternately. But there isnooutput yet. Good, the PFC works!Realising that it may not wake up unlessfed a signalby the battery to be charged, I simulate by feeding an adjustable dc voltage into the charging plug (via a diode to prevent backfeed if occurring). Raising the dc to 80V in steps did not start it.I added a 100R 250W resistor across, just in case it needed to source a minimum current to stay awake. Still nothing.What more can I do?Edit: SOLVED!
Hakko FA430 remote switch/internal pictures - Page 1

timestamp: February 13, 2020, 10:00:14 pm
content: I recently purchased a Hakko FA430 fume extractor.I have been really happy with it, but found the power switch placement to be a bit of a pain. I had to put my 430 under the bench back up against a wall and that makes the power switch hard to get to.No big surprise that the FA430 is fairly simple. The factory switch is just switching AC that then feeds a DC power supply. The DC supply feeds a small BDLC controller board that is very simple, it has a PIC that drives some FETs for the motor speed control. It is also keeping track of the amount of time the unit is on for the filter reminder LEDs.Wiring in a secondary switch is super easy and there is plenty of room (they really could have made the 430 much smaller). I chose to add an external connector wired in parallel with the factory switch. I wanted to try a foot pedal first, but if I don't like it I will probably just change it out for a remote switch somewhere on the bench.I have attached a few pictures, they are not great. I was in a bit of a rush.Cheers!

So remove the capability of wireless connection and add the capability of wired connection.To that end I'll obviously need to decode what is going on already. Now from the board layout I could already guess that for most buttons it's gonna be trivial (debouncing that on a teensy 4 isn't exactly a heavy load) but the optical sensor is making me a bit antsy.Do you have any further detail on it or the protocol it utilizes?Regards,Justus

content: I just got a pair of Hakko C1390C Omnivise PCB holders. They're about fist sized, stable and heavy. I think one of these is as heavy as the FR-830 preheater they're being used with. They have very smooth movement. The surface finish and knurling is quite nice. Adjustment is easy.The rubber pads in the "jaws" are a little bit of a concern. The outer edges of the rubber on both clamps are sticky. It appears that they're using a non-curing self adhesive rubber pad, and the adhesive sticks out a little at the edge.The pads also came firmly stuck together. Even after loosening the clamp, the rubber was too stuck to be wedged apart with a probe. Unscrewing the clamp with extra force pulled the pads apart, but I was concerned for the adhesive holding the pads to the metal. There was no evident damage. To keep the rubber from sticking in the future, I'll probably store them with the jaws open.All in all, they're nice units.

Significantly. The E-bike greatly if not completely, eliminates these issues.But we are not on a bike forum, but on an EE forum. And what I read here and other forums is that battery packs which are subjected to a significant load, appear not to have the anticipated or promised battery life.One thing is to replace a pack from a cordless vacuum, another is to replace a much larger (and expensive) E-bike pack.Does anyone here has experience with E-bike or other light transportation (Segways, etc) battery packs?

BMS boards seem very picky about playing with the cells and they will self-destruct easily, they completely die. And the engine management PCB talks about a lot of things with the pack (not sure how secure that communication is), so you can't simply build a pack and expect it to work on your bike. It is nonetheless interesting and no doubt a future thing that we'll need to master.Roberto EB4EQAwww.robertobarrios.com

Fy6900 crashing from severe noise - Page 1

timestamp: January 28, 2020, 11:02:23 am
content: I'm using the FY 6900 function generator as input to an ignition coil driver to test an ignition coil. After one or two test Cycles the generator stops working and doesn't output anymore square waves. Turning controls seem to do nothing. The only way I can get it to resume normal operation is to unplug it then input all my settings all over again. I guess the noise from the spark generator is so severe it is crashing the microcontroller inside the function generator. What a pain in the butt. I guess I'll have to think of how to Shield the function generator and or moving the spark farther away. Any other suggestions? I am generating a spark over .2 inches long which estimate it is about 20000 volts. I'm trying to adjust dwell time to get the desired maximum voltage output. Not too high but not too low. As I want to charge some capacitors but don't want to exceed their maximum voltage rating.At least it's only the cheap function generator crashing rather than my oscilloscope getting fried. When I saw no square waves on the scope it had to be either the school or the function generator..

I've read about a conductive paint to spray inside the case, but it can worse the things as can reflect back some noise generated inside.Maybe isolating with copper sheets the single boards is a better thing.I'm interested as i'm waiting my fy6900 and i'll use it in automotive ecu testing (testing coils and ecus)

content: I moved the spark gap about 1 meter away and it seem to not crash too often. Still can get it to crash sometimes if I change the freq and duty cycle.A warning of something dumb I did. I used it with a voltage offset so that the square wave would be from 0 to 3v P to P. That worked great for continuous output. When I tried the burst mode the off state is at the voltage offset that is now 1.5v not 0 volts so that my IGBT driver was not off or in a saturation and got fried!

The WE1010 i can get new one for 150 US $ and WD1000T used in good condition with two solider irons each 80W and support „start and go” for about 190$. Is this model really worth to pay extra money? Also will I have the opportunity to solider little SMD elements with these 80W solidering iron? I mainly will be using it to solider tht components and sometimes a few smd.

I am still on the original tip, it has been relegated to the second iron by a JBC which I think is a bit better but not by a huge amount.Perhaps my only issue is that my wd1000 doesn't auto - sleep when you put the iron back in the stand but having said that - I left it on for 24hrs or so without great deleterious consequences.

Theoretically you can estimate ampacity by measuring CSA.However, is this a good connection?A thought might be to strip the wire, ferrule it along the 'delta' split point to ensure a good connection there.I assume this is a bad idea?

content: You wont need the selection-switch on the smaller one. It takes 0,25 to 10 mm2 cables in one adjustment. They work fine.The bigger one only needs to be switched when you crimp over 10 mm2. The switch opens the jaws a little to make the bigger ferrule fit inside. (Note 10 mm2 and 16 mm2 is stamped on the switch)

Compact soldering irons - T12 STM32 V3.1S vs TS100/TS80 - Page 1

timestamp: January 09, 2020, 03:22:27 pm
content: Seeing the latest revision 3.1S of the STM32 T12 irons has me wondering about this so figured I'd ask.I've had a Hakko 888D station for years that works great for regular soldering jobs, but I've been wanting to augment with a fine pencil iron for more delicate work. Portability isn't a hard requirement but it would be nice to have something easier to pick up and move around than the 888D. I'm not looking to spend the $$$ for a Hakko 951 or a Pace or JBC right now, so looking at the sub-$100 range.I was leaning toward a TS100 or TS80 iron, but I kinda like what I see in these new KSGER T12 V3.1S irons. Seems like an improvement over the V2 models, although I don't know if it addresses ALL complaints. And I like that it uses T12 tips like the 951. It just seems a bit more "together" and rugged than a TS100/80, but the latter is awfully popular and highly rated for its cost. At some point I'll probably grab a TS100 anyway just for the field portability of it, but right now I'm just looking for a bench station.If someone has some comparative experience with these new 3.1S stations and cares to share their opinion, it would be appreciated!

The depth of field on the Leica is also fairly large compared to some. It is a bit pricey, even though it is considered the low end of their microscope line.https://www.leica-microsystems.com/products/stereo-microscopes-macroscopes/p/leica-a60-fI started with an Amscope, and sent it back after a day of use. I know alot of people here use them though. The model I bought would just fall over when extended on the telescope rail. Really turned me off to the brand. Felt super cheap too, but given their price I can see why they are popular.
