content: Engineer brand crimp tools are well-made manual crimp tools that work across a wide range of crimp contacts. It's a two step process, where you have to crimp the wire, and then crimp the insulation. However, for light crimping work, they're way more cost effective than manufacturers' crimpers. If you're not doing commercial, high-volume crimping, I would seriously consider this sort of tool.http://www.engineer.jp/en/products/pa21e.htmlhttp://www.engineer.jp/en/products/pa09e.html

content: Even a manufacturer recommended hand tool is going to be inadequate for commercial, high-volume crimping, simply due to the repetitive stress on the user's hand. Electric and pneumatic tools are made for this purpose. The point where a hand powered, ratcheting tool with locators becomes cost-effective is subjective, but they do allow more rapid and worry-free crimping. Depends what your time is worth.

content: Let's say high volume, relative to a hobbyist forum. Mass production volume and tools don't appear to be relevant to the OP.I would look at the amortized cost of the crimper over the number of crimps I expect to do over the next few years. If we're talking $1.00/crimp or more for a $300 tool, I probably would just skip a single purpose tool. You can always resell it, but selling tools is time spent not doing something else.

Yes, it's expensive, but something that RPN Fan Boys "need". Several of my HP calculators still work but I use the Swiss Micro calculator as well as RPN calculators on my iPhone. I will admit that I more often use the "algebraic" R command line that is always open on my desktop and laptop.

I don't mind if they're second hand, as long as they're in good condition, nor do they have to be OEM ones ($$$). I would be interested to hear if anyone knows a good source for these, or can suggest compatible dies from another manufacturer. This is what the crimping tool looks like:And here's an example die:

content: Having spent a fair amount of time researching, I'm going to try to answer this myself, and hopefully spare some future crimping enthusiast the same pain. It turns out that clones of the Holger Clasen EPC-39 crimp tool are legion, and that the compatible dies are often known as Beku / Izumi dies, where each die half measures 30x30x12mm and is held in place by a ball detent. These dies tend to be "double sided", in that a single set of dies will have crimp positions for two different size terminals at 180 degrees. I've found hexagonal, indent, trapezoid (ferrule), oval and rounding dies for cable areas up to 185mm2. Some of the sets I've seen (sensibly) combine smaller sizes with larger ones - so you might find 10mm2 combined with 185mm2, 16mm2 with 150mm2 and so on - others combine small with small and large with large (e.g. 10 + 16mm2 and 95mm2 + 120mm2) which leads to surprisingly flimsy looking dies for some sizes. Prices also vary considerably, I've seen individual die sets costing between £40 and £170 each (inc VAT). To cut a long story short, for the medium hexagonal sizes (25-70mm2), the cheapest option I've found are these"RS Pro" dies for their "THX-185" hydraulic crimper; £37 forthe 50+70mm2 die, and (strangely) £45 forthe 25+35mm2 die(inc VAT). I've not found a reasonably priced source for the 10 & 16mm2 die(s) yet. In case anyone is interested, below is a list of the tools I've found which I think use this type of die, many of which appear to be nearly identical:Izumi EP-50:Haupa HHs-6:OPT Tools THX-185:RS Pro THX-185(seemingly identical to the above):Rennsteig HPZ 50.1:Mecatraction HVD-51:Elpress V500(discontinued):BETE HCT-185(cheap Chinese clone):Add to that the Holger Clasen EPC-39, which started the search. All of these are 5-6 ton (50-60kN) hand operated hydraulic crimping presses, though I've seen both manual ratchet type and battery operated hydraulic tools which use the same dies.Edit:Some other sources for compatible dies:Borencotools: Haupa 185-H6 series(~€65 ea)KW Hydraulik: Serie 50(~€100 ea)Izumi Products: EP-50 diesHeamar: Rennsteig dies(~£150 ea)

It also has a lower evaporation rate than IPA so you get a longer working time when manually scrubbing. Fumes aren't too bad, however it is flammable.After cleaning with Safety Wash, I follow up by rinsing with MG Chemicals Super Wash (Aerosol). Then, I dry with DataVac electric duster. Seems to work pretty good.

content: I like using the Kontakt Chemie PCB Cleaner spray. Works great and comes with a useful brush on the end of it to scrub things. No need for any tray to work in, just use it above a trash can so you can just spray at it and let it drip off. A bit of a blow to get the liquid off and a quick paper towel job and its done.But IPA is cheap, easily available and works great. It can be made to work better by mixing in some pure ethanol.EDIT: Oh and most flux cleaners that are any good will be flammable as heck. Just don't smoke next to it and don't leave it exposed to the air and you should be just fine.
OPTO-EDU A22.1201-C1 Soldering Microscope... Like AmScope SE400-Z, But Less $$$ - Page 1

content: https://www.amazon.com/gp/product/B0747R2M25/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1I bought this scope to solder micro electrical components. The specifications, right down to the words and expressions used, appeared to be very similar to the AmScope SE400-Z. However, this unit was less expensive.The scope is extremely well made. I was expecting much less, because of the price. However, everything is topnotch… fit, finish and materials. The base has good weight, making it reasonably stable. Even the power cord is supple.From the advertisement photographs, I had noted some discrepancies:- The box under the eyepieces is shorter.- The horizontal bar clamp might be located at a slightly different place, along the bar.- The light switch is located on top of the base, which I prefer.- The knurling on the adjusting eyepieces is slightly different.For the unit I received, the lamp is not a LED… maybe halogen? But, it is very sharp and bright. I would not have been happy with a single LED. It does make some heat, however that is not a problem.The acid test of acceptability for me was if the focal range would allow sufficient room to work a soldering iron under the scope head and the unit not be so cheaply made, as to not be expected to last. I wear 2.0 reading glasses. Without my glasses, and using the 10x lens, I can fully focus on the object and have just about a full, vertical iron’s length, below. That is about 6-1/4 inches. The field of view is adequate. I have already commented on the unit’s superior construction.Because this is my criteria, I am not concerned, if there are any operational differences to the AmScope. And, this review is not a heads-up comparison of the two. This scope simply does (well) what I wanted it to do and was the little bit of less expensive needed to meet my present/immediate budget. I am pleased with it and can recommend it, if your criteria are the same as mine.Budget Note: The Amscope/Prime does not charge tax. This unit did charge tax, but the sum of the price was still cheaper.

TL866 I2C programming problem - dodgy adaptor PCB - Page 1
Forum section: electronics / general

author: Ash

timestamp: February 09, 2018, 02:19:47 pm
content: Hi,So a while ago I bought a TL866 and it came with a bunch of PCB adaptors to allow it to program non-DIP chips. I've used it a few times to backup EPROMs from old test gear (why I bought it in the first place) and I've had no problems, its been good.However today I needed to use it to program some SOIC8 I2C EEPROMs mounted on a PCB - cool I'll just use the dedicated cable and clip that came with it.Well.. so I thought. It always read zeros, and if I tried to program it, verification would fail on the first byte. bugger...So after a lot of messing around, involving pulling a chip off the board in case it was something there, I hooked up the scope and what do you know.. yep SDA line is ground.. hum.. buzzed out the connections and there was a short on the board between Ground (IC pin 4) and SDA (IC pin 5).So I fixed that and all was good!This looks like it could be common as the ground track is very close to the pad.So if you have one of these, do yourself a favour and just check for a short before you try to use it.Ash.

content: Quote from: vze1lryy on February 11, 2018, 01:00:51 amI like the TL866 as well, but the ZIF socket is pretty cheap. But for the price of the unit, its awesome.The clip seemed to work ok for me, but you have to be careful to get it aligned properly. Also if the chip is on a board, make sure the I2C address lines and Write protect are not being tied directly to gnd/vcc (its pretty common for them to be directly wired). The circuit I used had 10K pullup/down resistors on all these pins and the TL866 was able to drive them properly.It would be cool to have the ability to configure the address to use for the I2C bus communications for an IC in the MiniPro application to get around this..Actually, thinking about it, if the TL866 has to "power" the rest of the circuit though the VCC pins on the EEPROM its not going to get very far. I was luck in that the EEPROM was isolated from the rest of the circuit (its on a plugin card and is used by the host to identify the card).Ash.

How to measure low inductance - Page 1

content: Help please. I'm getting a bit frustrated trying to find an affordable LCR meter that will measure low inductance for a project that I'm working on. I have to wind my own inductors so I want to test them before I install them. They are in the range of 140nH to 3uH. It seems that all affordable meters bottom out at 20uH (i.e. MASTECH MS5308 or IET DE-5000). Any suggestions?

It is measuring my hand-made 3uH inductor very accurately. in the nH range I'm getting readings that are close to what I expect, but the values move around quiet a bit. I am suspecting my measurement method right now. I'm going to try cutting the leads closer to the core. I'm suspecting at the very low range that the lead length might be an issue.

content: As I measure small inductances that quite seldom, I use the parallel resonant circuit method.I connect a precision capacitor of 100 or 470pf in parallel with the unknown inductance and I feed this resonant circuit with my high frequency generator through a 4k7 resistor.I am looking for the resonance frequency (maximum voltage) and calculates the inductance .... the resonance frequency is known as well as the value of the capacitor, which allows to calculate the value of the inductance.I use the probe X10 of my oscilloscope and I take into account the input capacity of my probe.

However my current PC doesnt have a parralel port and the only PC I have that does is not working at the moment, its not really able to be used for that.Afterward the router needs to be told about the extra memory.Many people have told me just to forget about it. They are so old, etc.But I cant just throw it away, its an old friend.With two new chips it can run current SW.So, according to the open OCD web page, the traditional old JTAG cable was the wiggler.http://openocd.org/doc/html/Debug-Adapter-Configuration.html#Debug-Adapter-ConfigurationWhat would be a good way to replicate its functionality now?Its likely very simple, what I need to do, at the beginning, but since its fairly straightforward I am going to add the JTAG header.I guess what I am asking about is cross-compatibility. Will the newer JTAG cables work.I think I can make my logic analyzer into a USB-Blaster compatible JTAG cable.Can I use that to debug a Broadcom-chip based Linksys router?

content: New guy here, slowly binging through all of Dave's videos.I'm building a new work bench to separate out my electronics-tinkering tools from my general purpose tools in the hopes of smoothing out my workflow when I have a specific project to work on. I tend to spend time looking for a tool I used somewhere else at some point since I last worked on a project.So we all know what's on Dave's bench (huge mailbag knife, tiny DeLorean), but what's on yours (other than the usual big guns like the scopes and meters)?

content: "Electronics Engineering Toolkit PRO" or "EE Toolkit". (£6.99)There is also a non PRO version which is free. As can be seen from the screen shot it can do lots of calculations. So for example you can click on "Transistor" and you get multiple tabs such as calculator, NPN & PNP switch, biasing, mono/bi/A stable calculators. There are calculators for RLC circuits, OpAmps, Mosfets, LEDs, 555s, voltage regulators, resistor codes, ohm's law, PCB track/cable thickness calculations, wire ampacity, AWG, RMS, propagation delay, frequency, nm to colour, speed of sound and passive cooling.All in all a very useful and comprehensive package. Not as cheap as some but £6.99 is hardly a lot.

content: I'm putting together an equipment budget, and I don't like how much the JBC equipment costs, especially their tips. I've used JBC gear in the past, and it's fantastic, except for tip wetting and tip life, which didn't really impress me.This is what I was considering:JBC DMSE-1A (Quad station, T245-A soldering handle, DR560-A desoldering iron, stands and a pump)JBC PA120-A Micro TweezersJBC PA-SD Tweezer StandTipsPossibly I would eventually add a T210-A handle and stand.Can anyone suggest alternatives that might be easier on the budget? I looked at Ersa, and it seemed like to get the same power and versatility, I would need to spend more (at least in the US.)My use case is mostly rework down to 0402s & 0.5mm pitch. Very occasional 0201 installation, when I have to add passives across the leads of a fine pitch IC. Also rework of larger SMT components with no thermal relief on planes in power circuitry. I have a good hot air station already.Thanks!

My plan is to use a spare MCB from the workshop consumer unit directly to the isolation transformer and then one output to a red double socket above the bench.Should I add anything else? As it is a 1:1 240v isolation transformer will I need an RCD after the transformer? Will a short trigger the MCB's RCD in the consumer unit?https://www.ebay.co.uk/itm/REVCO-1-1-240V-3KW-ISOLATION-TRANSFORMER-IN-CASE-CENTRE-TAP-/292420151747?

Probably using diferent test frequency or something..I have few of those capacitors and I am planing to do short video on that.

It is using DLIS-2K linear optical sensor that is quite fast (up to 41000 fps), as I guess cheaper slower ones (like TCD1304AP) are too slow to be used on in this rotating setup.Still, even with this fancy sensor it is massively simpler and cheaper than big boy LIDARs (SICK, Velodyne and the like) or RGB-D cameras.

Help with Pace ST 50 soldering station (SOLVED) - Page 1
Forum section: electronics / general

author: pro-sl
author_rank: Newbie
timestamp: January 21, 2018, 04:44:55 am
content: I recently acquired a Pace ST 50 station with TD-100 soldering iron. It is in great shape but going by the design and the 1.2 software version it looks like an earlier production. I went through all the settings in the menu and it appears as if one feature is missing. If one is in the setup menu they can choose C or F, temperature range limits, set back time, auto shut off and THC calibration offset.My menu ends after auto shut off time. I am not sure if THC calibration offset is missing or if it only is available with special tips or irons.From reading in the manual about the three different offset modes I am not quite sure what the offset actually is or refers to but my guess is that it has something to do with calibration.When changing a tip with the unit on I get an amber light and the display reads O(or zero)SE then a green when the tip is inserted again. Then it displays the rising temperature and acts normal. This behavior is not mentioned in the manual and I am wondering if it is something that is unique to older/earlier models.I am also trying to figure out if the unit is operating properly. I only soldered something for 5 seconds and it seems fine in that regard.Thanks for any input.Update: I emailed Pace directly and they got back to me right away. My station is indeed an earlier production year and the older software version does not include the offset mode functionality of the newer stations. Other than that they are the same.
