content: Just wondering if there are any users around and what exactly people do with it. I know the equipment and licenses are rather expensive for the hobbyist but sometimes, there are good deals on ebay, so it's not completely unreasonable to see a hobbyist with such gear.To start, I use it at work on a daily basis for the PowerPC architecture to work on low-level MCU stuff at an automotive supplier (PowerDebug II/Pro, PowerTrace II, PowerIntegrator II).At home, I use it for Cortex-M to work on my hobby projects (uTrace, PowerDebug II, PowerTrace II, PowerIntegrator).While I'm at it - anyone got an LA-793x ICD PowerProbe or LA-7949 analog probe?

Perfect user experience in debugging from ARM9 to Cortex A57.Would like to buy it for home use, but have no idea about price range for Cortex-M.Would like to know pricing in that segment. Tools that I used were in 20K EUR range plus 1k eur yearly for software. Way out of hobby budget.

content: Due to the rapidly increasing difficulty, most ASICs will NEVER reach ROI, even if you have free electric. Remember, you need to evaluate it based on the amount of crypto it costs versus it's earnings in crypto after expenses. Dollar gains due to crypto price going up are fake profit. If you make less crypto than you spent, you lost. You would have been ahead by just buying the coins and holding them.What's with all the damn lights? Is it a tool or a showpiece?It's UI is done through the cloud. This alone is reason enough to consider it junk. ANY device which requires a cloud connection to function puts you completely at the mercy of a 3rd party. Their server goes down, your device is dead. They go bankrupt, device is dead. Maybe they decide you need to pay a monthly fee to use your device. Maybe they declare it "obsolete", etc.Ed

content: I have never considered mining ASICs a good investment except when they're really cheap. Near the beginning of the year, a bunch of investors spent a lot on some high N Scrypt ASIC boxes (something like $1800 each), expecting them to pay back in like 2 months, but the adoption of those ASICs skyrocketed the difficulty and it would be more than a year before they pay off.

Need a source for USB-to-UART CP2102 modules with MicroUSB - Page 1
Forum section: electronics / general

author: Peabody
author_rank: Super Contributor
timestamp: July 09, 2018, 05:27:25 am
content: The subject modules look like this:https://www.ebay.com/itm/113116825693There appears to have been a very large batch of these modules that are defective. I bought bad ones from one Ebay seller and from Banggood. These bad modules have an error in the board layout that connects pin 9 (Reset) of the CP2102 to USB V+ (5V). That raises the voltage on the regulated "3.3V" pin, as well as DTR and TXD to about 4.3V, or about one diode drop below 5V. Of course that could be disastrous if connected to a 3.3V processor since it would likely exceed the absolute maximum ratings.I found one Ebay seller who provided good modules, but his source has now dried up, and I no longer have a source for good modules.If anyone has bought any of these modules recently, and if they are good, I would appreciate a link to your source. The good/bad test is simple. Connect the module to USB and measure the voltage on the 3.3V output header hole. If it's about 3.3V, it's good, but if it's more like 4.3V, it's bad.By the way, the cure for a bad module is to just cut the trace connected to pin 9. The chip works fine with Reset floating, and the voltages return to normal.
Analysis: piezoelectric air pump - Page 1

content: Very recently, Big Clive did a video on a piezoelectric air pump:I decided to get a 120V version for a simple project I wanted to play around with (atmospheric CO2 sensor) and I decided to open up the plug to analyze the circuit inside. The circuit is basically the same as for the 240V version:* It has two 2k resistors in series instead of three 8.2k.* The capacitor is the same but the inductor is 1.4mH.* The silly 1M across the first resistor is there, along with another 1M across the pump.* The pump itself measures about 63nF.Not sure the exact purpose of the inductor. I was expecting it to form a resonant circuit with the pump but probing with a HVP70 probe across the inductor showed almost no voltage. Something interesting to note is that with the probe across the pump, the voltage slightly increases when the output is blocked.

content: Probably a good pairing with a CO2 sensor to get a faster response and avoid dust buildup. Although if you don't care about response rate much, the air will circulate reasonably on its own.If you use a PM sensor those will have fans so you can use that to blow near the CO2.So it really is running at 60Hz? I had just assumed that is far too low for a piezo, at least optimally.Maybe you can try a higher frequency as suggested in the comments (but wouldn't be at 120V).

feedback circuit on battery powered dremel? repair - Page 1

content: So I was brushing rust out of some nooks and crannies on a vise I could not get at with any other tools and my dremel halted, I thought the battery died or it overloaded. I was just using a mini brass brush. I typically use a dremel fan accessory with it so it blows away the dust from the air intake ports.I charged up the dremel pack and it did about 1/2 a turn and stopped. When I attempted to power it back up after it stopped it did not respond.It was not hot or being used heavy at the time of failure, just very gentle brushing.Likely failure modes? I can't find much on the battery powered dremel repairs. If there is something likely I would like to try to repair it but I don't know if maybe trying to get the company to repair it is a better idea.I thought that maybe there is some sort of thermistor or NTC inside? I don't know why a motor control would do 1/2 a turn and stop spinning unless something is over loading.

content: I'm looking for suggestions for a commercial America to Europe converter. For household, not Lab.It should convert 110 V 60 Hz to 220/240, 50 Hz. It needs to deliver around 20 Watt.The shape of the output signal isn't very critical. It has to be sinosodialish, but doesn't have to win a beauty contest.It has to drive a synchronous AC motor so frequency stability at the output side is more important.Drift over time is not critical, just not a lot of short term frequency drift because the receiving side is a turntable.I would appreciate if you know of such a product.

Power "regulator"? - Page 1

timestamp: June 09, 2018, 08:49:40 pm
content: So, I've found the video below on youtube. It shows a quite interesting device: When the mains voltage is below or above a certain range, it disconnects the power from the outlets (preventing damage from brownouts, constant power cycling and voltage spikes). It takes some time "measuring" the voltage and if it is on an acceptable level, the outlets get energized. The only thing that made me worry are the fluctuations when the circuit re-energizes the outlets.Is it feasible for a whole home power regulating circuit (with the obvious stepping up)?

Those, while having the most dodgy of SMPS units inside, often with non existent mains isolation, do at least give you the adjustable fingers and mounting to hold most flat battery packs in place and make contact with the connctions. Remove the junky inner converter and add your own external one with better charge control, or use the included and use a " do not touch while plugged in" approach for it.

In it is a 200GB SD card made by Sandisk.It's worked great for the past 2 years, but I'm having a really weird problem with it right now. I bought a new album the other day and put it on there, and the songs sounded great. There were lots of weird spikes of different frequencies that just sounded bad, kinda like there was a wah pedal in there somewhere. I then play the files on my computer, and they sounded fine. So i tried resaving them on the SD card, but it still continued to sound terrible. I can even save them to the SD card, and play them on my computer, just selecting the files on my SD card and they still sound bad, so I don't think the problem is the player. All the other music that I know of on my SD card sounds fine (at least the random songs that I was selecting did), and if I save the music on the player it sounds fine as well, it's only when I play the new music that is on the SD card.Any help?Thanks

I'm eager to try this new kind of technology which the heating element itself built in with the tip. Right now my current setup is Quick TS1100. Had it almost a year. It pretty much a Hakko FX-888D with better interface plus auto sleep features. Back to my main subject, these 2 stations use same tip technology as JBC. Normally on this forumers would straight recommend JBC station but I lived in Malaysia and hard to get JBC stations with Warranty around here. I'm left with either Hakko FX-951 or Goot RX-802AS or RX-852AS.Goot RX-802AS power rated for the handpiece 72W, RX-852AS = 150W and FX-951 = 70W (if I'm not mistaken).As for price the FX-951 is around $410 in Malaysia whereas Goot RX-802AS = 230$, RX-852AS = $380.If I'm going choose FX-951, I'm better of with RX-802AS for same amount of power for less money. But the RX-852AS is rated 150W for $380, is there any big difference in term of extra wattage?Here's link for RX-802AShttp://www.goot.jp/en/handakote/rx-802as/RX-852AShttp://www.goot.jp/en/handakote/rx-852as/p/s : the RX-8 series tip only cost around $11-$20 which is cheaper than T12/T15 tips

content: I need all the help I can to do fine soldering work and I have settled on my reading glasses + a pair of Donegan Optivisors (1.5x for work and 2.5x for inspection). While these are great, I do get eye strain after a while (maybe due to optical center alignment - possibly just eyes getting tired).Does anybody have experience with the dentist-style glass-mounted loupes? I see a bunch of offerings on the web and found a couple of people recommending Craftoptics as an economical alternative to the pro-grade stuff the dentists use.I did find one post on the Craftoptics:https://www.eevblog.com/forum/reviews/safety-glasses-suggestion/msg330478/#msg330478

content: I bought a set of thesehttps://www.amazon.com/Surgical-Binocular-Loupes-HeadLight-Aluminum/dp/B00HEVYELOand I prefer the Donnegan visors. Be aware that the little lights attached are a pain to use and just add weight.I purchased the cheapest Donnegan with glass lenses and some replacement glass lenses in different powers; I don't know why there is such a price spread on Amazon for them. I find it is easier to get the Donnegan visor in focus.The cheap telescope ones you listed have a lot of drawbacks. They usually don't have individual focus like most binoculars if your eyes aren't the same. They are hard to bring both lenses to focus for true 3D vision. Anything over 3.5x will lessen the focal distance and the field of view. The true medical ones that cost $500 plus are usually made to order for your eyes, preferred working distance and power. Last time I was at the dentist's office I asked to look through some good ones and the difference is astonishing even though they weren't set for my eyes. The working distance was about 500mm and the field of view far greater than the cheap ones. It is like the difference between a $20 set of binoculars and a $400 set.

Right after I could smell burnt material and then I saw this purple color. Usually it should be "rusty" chrome effect as it was on previous and on Dave's. Is this fake part or it is high temperature for the first run?PS Yes its a spare enclosure, I melt plastic alot!Edit: better picture

Probably got a thin layer of oil or something to help prevent initial rust but you don't want those vapors.Just crank it up, once the soldering flux fumes etc hits it will start to change color. But original or clone it's only function is to hold the tip in place, as long as it's the correct size.If you brought the part from a Chinese website or a seller on Ebay or Amazon a lot of them sell fakes. If you did send me a PM with a link if you like and I'll tell you.

However Antex have a number of different series irons with different shaft diameter heating elements, so you'd need to measure the I.D. of the bore, with the spring clip slid towards the tip till its just off the slit section and if it shows a any signs of splaying out, with the sides compressed just enough to make the slit the same width for its full length.

"Safest" solder flux? - Page 1

content: Hi all,I've been soldering for about 10 years, since I got started with electronics in high school. Now, I solder every day as a practicing EE. Of course, I try not to inhale solder fumes while soldering, but it is somewhat inevitable. Sometimes I get nasty headaches after soldering a lot. I'd like to use a fume extractor, but my current bench setup (at work) is quite cramped.So, my question is: is there a brand/line of solder that uses flux that is less detrimental to human health? Any ideas on this?Thanks.

content: If this is for work, then you need to make it clear to them to supply you with the proper equipment.An articulated arm type fume extractor is expensive but does not take up any bench space.Low solids like Kester 951 would likely be the best to avoid particle inhalation, but you are still going to be breathing in ethanol/methanol/isopropyl etc.https://www.kester.com/downloads/sds

They did provide me a fume extractor, just I haven't figured out a good way to incorporate it.Thank you for the suggestion. 951 appears to be a standalone flux. Looking a little bit harder at Kester, it seems that 268 wire solder is perhaps the "healthiest", but seems hard to come by especially in leaded variety.

( I am still waiting for some equipment to arrive which will help with debugging - but photos, etc... )I would post photos, updates, questions, etc... as I progress through it to find out what's wrong with it... Obviously first step will be to check the power board and if good, trace to see where power was stopping... The unit itself is old.. I'm not even sure how good the resolution is - it has a Hitachi bulb / projector Make: 5DEP31 (F) in it... The entire enclosure is about: 7" tall x 11" wide x 17.4" deep / long and the Hitachi runs about the entire length...Front with controls - top lid is popped / propped up but you can't see in yet...https://www.dropbox.com/s/9603r0uenxob1zf/20180507_123333.jpg?dl=0Rear with power cable wrapped uphttps://www.dropbox.com/s/0sowu7cfveuty7v/20180507_123355.jpg?dl=0Power cable unwrapped so you can see the bottom left info plate.https://www.dropbox.com/s/mo1imgbbgnqqcjo/20180507_123423.jpg?dl=0As soon as my phone stops crashing when I take a photo, I'll post some more... and I'll look into taking this apart or doing something with it soon....

content: I have a HP 2015dn printer. My wife prints reams of junk from the internet without regard to how much toner or paper she uses, so we go through a lot of toner. The quality of the aftermarket stuff is all over the place so I just wait until enough complaints make it necessary to replace and then buy from Amazon because of their great return policy. I immediately switch in the new one and send it back if it doesn't meet expectations. None of them are as dark, fine texture or last as long as the real HP, but for the price have worked well after lasting beyond the return window.The trick to Amazon is to only look at the 3 star and lower reviews; most of the 5 star reviews are bogus.

content: Here is another thing to think about. The really cheap 3rd party cartridges, especially re-manufactured, can leak toner into your printer. It is a bear to clean up and to do so, you really need a special vacuum. You don't want to be breathing that stuff in either as it is classified as a 2B carcinogen. In the early 2000's, I had plenty of experience with crappy 3rd party cartridges when I was servicing Lexmark laser printers. There was a family owned pharmacy chain that absolutely refused to use OEM and they bought the cheapest that they could find. The leaked toner would foul up the printers, generating regular service calls. They refused to listen to me about the issue and after I reported them to Lexmark, Lexmark threatened to cancel all the warranties on their printers. My service calls virtually stopped after that.Personally, I don't print much from my own laser printer so I will buy the OEM so I don't end up with a crappy cartridge and have to clean toner. Especially that I don't have access to that special vacuum any more.

content: Dear friends,as some of you might have noticed, I acquired a bad case of GAS over the last couple of months. Diving deeper into micro soldering I stumbled upon the discontinued TS4-S-2C Dynascope from VE in mint condition that was just an offer I could not refuse. That is the variant with 250W lighting, rotating 30° oblique viewing attachment and came with 0.7X magnification lens, so it zooms from 4.2X to 42X magnification.I am wondering what camera adapters were available at the time.I have been in contact with VE support in Germany, but they do not seem to care about the devices they sold 15 years ago.I would be interested in either seeing some photos of the adapter, dimensional drawings or even buying a used part / NOS / whatever comes along the way.My plan is to build a suitable C-mount adapter and maybe also a 6000 lumens, high CRI COB LED retrofit for the fibreoptics illuminator - the 250W halogen lamp has a pretty noisy fan and sinks quite some amps just for illumination.Also, getting a graticule insert and other magnification lenses might be a thing, though I am pretty happy with the as-is state right now magnification wise.One more thing:The unit has a "Multiplug" multiple-outlet power strip mounted on the side. Is this something proprietor to VE? I am missing at least one spare plug to make a cable for the lighting unit.Thanks and kind regards,Frederik
