Thank you for sharing this tools. More power to you Andreas.
You are welcome!
These kinds of videos are extremely valuable for me. Thank you!
You are welcome!
Thank you for sharing your often overlooked tools.
You are welcome!
The step drill bit really is essential for anyone working with plastic or thin sheet metal enclosures. I didn't know about the adapter PCBs for smd parts, nice tip!
Till recently, I did not know about them, too.
Excellent as usual. I ordered the Ferrule and transistor checker - great ideas.
Enjoy! Good choice.
I am started with some electronics work in IoT after some years absence. So your video was extremly helpfull for me. Thanks Andreas!
Glad to be of some help!
Guitar pick to open plastics and Dental tools for pins and other jobs I use. Love the way you drill holes. Have a wonderful day.
Thanks for your tips!
Thanks for the video. Along with the alcohol, I use wooden shaft Q-tips for clean-up in tight places. Helps to get rid of flux, dirt, and oils from my grubby hands.
Good Idea. And I discovered, that I forgot the toothbrush to clean PCBs from Flux
Great ideas...I found that when using a needle applicator bottle even with a tip protector that flux will dry in the tube and can be a pain to clear. So now whenever I'm done applying flux for the day I simply remove the bottle top and clean the tube out with a little IPA. I also keep IPA and flux in three different containers for different applications - a nail polish bottle with brush, the needle bottle and on of the larger bottles like you display; same three containers for IPA. Really like the flip-up bottle for grabbing some IPA on a cleaning cloth or Q-tip.Thanks for sharing Andreas!
You're welcome. I forgot to say, that the flux will dry out, as you experience. But the same with me, with a little IPA It usually can be cleaned.
Danke vielmal für deine informativen und ehrlichen Videos!
Beste Grüsse in die Schweiz!

Dear Andreas,
I agree with you that the old fashioned wire strippers are very handy, but for most of my wire stripping I use the Klein Tools Katapult. It is like the automatic strippers in that it strips the wires for you, but unlike those it grips the wires from all sides. It does this by having many different wire sizes to choose from, like the old fashioned strippers. It works very well for me, and I think it might be worth a try for you.
I once even made a video about strippers and I think, other viewers also recommended the Klein tool.
very nice explanation and show ! thank you, very helpful.
Glad it was helpful!
Tinning the wire with solder is not recommended when connecting into a screw terminal block. Over time the solder collapses and the connection may become loose and high resistance. Bare wire strands are the best for screw terminals blocks - the wires spread out under pressure and maximise the surface contact area. Of course care is needed to ensure there are no loose strands hanging out that could cause trouble. As you mentioned, ferrules are neat and tidy but it is critical to match the wire size correctly and crimping needs to be done carefully. I have seen instances of bad crimping causing trouble with connections.
Thanks for your clarification
Is there any chance you'd be willing to share a link to your gloves? They look like a great mix of comfortable and usable.
Very helpful and time saving. I just bought the Brother PT-700. For me it looks like it is still the best choice (preiswert=what you get for your money). Only 35,- € (Völkner, no shipping costs when choosing "direct pay"), arrived the other day. Happy labeling! To get all features do a software install.
And if quality is not so important: www.banggood.com/Black-on-White-Label-Tape-For-Brother-P-Touch-Label-Maker-12mm-TZ-231-p-952215.html (this is, how I do it)
Yes, had done that already. That's part of the - good - deal :-))
Thanks for helping us to learn. Great Job!
Thanks!
Did you try to use an alternative box configuration for the resistors? I am using it for in my labs and works pretty well for slow-runners values. On top of that, and only for few fast-runners as 47, 100, 220, 1K, 10K and 1M I have in separate boxes 100pcs of each of them in little boxes.
And example of this configuration could be seen in www.ebay.com/itm/145-Values-Total-10pcs-each-1-1-4W-Metal-Film-Resistor-Assortment-Kit-1024-/272189800972?hash=item3f5fc6c20c
Seams also to be a good concept.And it is very small. Maybe I give it a try. Thanks for the link!
Thank you for sharing.
You're welcome!
Those hakko tweezers along with the bent end ones are my favorite.
I am glad these old videos are still watched!
@Andreas Spiess you're 1 in a million my friend. Hardware may change but certain information is timeless.
ferrules changed my life. i love them.
Me too!
@@AndreasSpiess The link to buy this is broken. I did find another one on the site, but they seem to have done away with "add to wishlist" and I will not be buying until an issue with a current order is worked out...
Very informative as always. :)
Thanks!
Very very good work
Thank you!
Great tips, thanks Andreas! So many projects, so little time, how do you do it???
You're welcome. We all have 24 hours a day. If you get old like me, your time is limited. This is, why you need less sleep :-)
Hey mister, you are pretty good with that 3D printer. I like that P-touch. Nice video.
Actually, I had to replace the 3D printer, because it did not work anymore...
Where did you get your gloves? And are they for protecting you from shock or the devices from damage? Thanks for this vid, really practical, love it
I got them from AliExpress and I have private reasons why I wear them. None of the ones you mentioned.
Have you tried using heavy duty tin snips to cut your PCBs? I find them easier to use than a hack saw - and it doesn't generate the fiberglass dust.
No. But it is a good idea! Thanks.
I just use my Dremel with a cutoff wheel.
With the cheap proto boards, I find they snap unexpectedly with the tin snips. Instead, I have a 10" bandsaw, it makes short work of cutting PCBs.
Definitely getting me that transistor tester :)
:-)
I know this is an old video, but I wanted to add a comment about the prototype through-hold PCBs. They are really useful as a template when soldering pin headers. I drop the headers through, put the small board on top, and solder. Out comes perfectly straight, perfectly spaced, parallel pins that easily go into a breadboard.
+Michael Graff Many of my old videos still get a lot of views. So, thanks for the tip!
I thank you for your videos, and curse you for introducing me to LoRaWAN. I'm in the process of building an ESP-32 based fully featured single-or-multichannel gateway, as well as building an ESP-32-focused node library. Fun times!
+Michael Graff Great. Just tell us, when you are finished. Maybe I make a video...
hey andreas great video I was just wondering you seem to have some expertise in esp projects. Have you ever come across a small solar box/with a small solar panel with an esp attached which does some sun analytics for you,and pushes data to your IOT cloud. so you can get some stats before you invest in lots of solar panels? Is it ever sunny in Switzerland?
Sometimes we have snow and sun ;-) No, I think, this is a special device which has to be built. And maybe WiFi would not be sufficient, because on the roof, you might not have one. I think also, there are probably more accurate sensors to measure light than just a solar panel. But I am not a specialist in that.
I have a project plan for me to measure the sunlight and compare it with short term weather forecast. Because it is not so warm here, we need heating. But if we would have a good short-term forecast, we could reduce sometimes the energy.
I use printed labels on wires with clear heat shrink works really well
Good idea. Thanks.
I have one of those component testers, and it's one of the more-used devices for my setup. No 3d printing capability here, so I put it in a metal tea container with three banana jacks added besides putting stuff in the ZIF socket. The link you provide is about half the price I paid for mine. :-)
Your solution is probably even better because it is shielded...
I'm not sure that matters. It was also convenient that I had a couple of sets of test leads that went with my curve tracer. I saw another such unit that had a connector in place to attach leads, and it came with a short set of wires with clips. Next time I buy one I guess there will be more choices.
This is really useful, thx :)
You are welcome!
I'm curious Mr. Spiess, why do you use SMDs which need soldering to PCBs with headers before being used on your protoboard? What advantage does it offer over using a through-hole component?
I use SMDs if I do a PCB. And for many of my projects I do PCBs at the end. They are easier to mount (no holes), need less space on the PCB (also because you can mount them on two sides).
Thank you.
I've found that a good quality step drill bit will drill through aluminium and thin stainless (i.e. rack mount gear) fine.
Thank you for the tip!
A small correction - Those step drill bits also used to drill steel and aluminum.
True. I just do not do it.
For tweezers, go check out cosmetic tweezer kits for blackheads & skin care. They're extremely fine and great for extremely small parts. Also, there are some tweezers that have replaceable heads that are either ceramic or plastic - in case you're worried about static. But the cosmetic tweezers I find are the best.
Thank you for the tip!
beside a Brother label printer i use a DYMO which also can print Barcodes which is very handy to read it with a smartphone and access a local database at an raspberry pi
Mike Herbst I know the brand, but never owned one. So, it is good to know. How are the prices of the consumables? This might also be a deciding factor for the viewers
there are also 3rd party products for an 3rd of the price :-) so about 1-2 Räppler per label
"We will not be rushed, we are at work and not on the run!"
:-)
well could you please suggest me some good Chinese microscope for micro-soldering work? & thanks for sharing
No, because I never tested a good one.
I am curious about your gloves. Do they have a specific properties or material needed to do electronics hobby?
The gloves are not necessary. You can ignore them
Hallo Andreas,
vielen Dank für den Einblick in deine Werkstatt! Ich glaube so einen Bauteiletester muss ich mir auch mal besorgen...
Ich wollte noch fragen, was du für Erfahrungen gemacht hast mit Aliexpress und Zoll...
Alo ich habe kürzlich eine Bestellung bekommen mit einem Warenwert von 88 USD... dafür musste ich dann 41.- bezahlen!!!
13.- für Besichtigung und Lagerung, 18.65 Verzollung Zone 2 und 9.45 Einfuhrsteuer... ganz schön Happig...
Mir wurde dann auf der Post gesagt, dass ich besser unter 65.- Bestellungen machen sollte...
Gruss
Stefan
1. Der Bauteiletester ist eines der erstaunlichsten Geräte, das ich je hatte. Und alles für 10 CHF.
2. Die Zollobergrenze für CH ist 5.- MwSt. Deshalb die 65.- (allerdings zählt das. Porto ebenfalls zum Wert!!!). Grundsätzlich ein guter Tip.
3. Meine Pakete von Aliexpress werden selten geprüft. Sie sind oft klein, und die Deklaration nicht richtig. Einmal wurde ein Paket geöffnet, und der Wert war offensichtlich falsch deklariert. Da habe ich auch eine gesalzene Rechnung bekommen, weil wir für die Chinesichen Lieferanten bürgen. Das is 1 aus 1000. Du scheinst einfach Pech gehabt zu haben.
Have exactly the same stuff !!
Do you have a link to the printed box design files for the component tester? Mine flops around with the 9v battery hanging loose.
Excellent video as usual.
Thanks. The box is already there: www.thingiverse.com/thing:1694729. I just forgot the link.
You did mention it in a few videos back on the tester.
I love mine. so accurate too. need to make a jig and solder it to the empty TO package, besides the zif socket, to make measuring resistors and caps easier and don't wear out the socket. I have hundreds to go through. Some bags of 1% mixed resistors and capacitor grab bags, will finally get a proper place.
So far, I buy them "unmixed", but during work, they sometimes become mixed. I just bougth a set of 103 values, because I often did not have the right one. Now, I have the problem of storing them properly
Andreas Spiess
Glad to find out I am not alone :)
Specially after dismantling a big breadboard project... putting the resistors and capacitors away is a pain.
So it accumulates, until their is a hairball-like mess to sort through.
You are the first one I see who pronunce Hakko the right way
Thanks!
I've never seen so many open tabs in a browser before! 😲
Bernhard Hofmann with big screens this is no problem anymore :-)
I once was self surprised about the "67 Tabs restored" message on a chrome restart :)
Yesterday I closed Firefox, and got the message "are you sure you want to close 159 tabs" I guess I have some kind of a condition? ;-))
Andreas Spiess unless u run chrome. Or are u actually rocking 12 petabytes of ddr9?
now imagine same amount of tabs in 4 windows...
Simple electronic tool kit
Soldering iron, desoldering flux ,solder,cutter ,transistor tester , multimeter
This channel is more geared to the ambitious Maker...
@@AndreasSpiess thanks for replying
Very interesting, have to spend some money now ...
Christ mas is coming :-)
Wondering how crimping provides a better connection than tining?
Even if crimping creates a weld (which I have heard is the case) wouldn't tining still cover more surface area?
I am no specialist but it seems that the specialist agree. And crimped connections are more robust against vibration.
@@AndreasSpiess Thank you for the reply. I was not expecting that!
That makes sense though, for any case where vibration or force could be applied to the joint, crimping would be preferred. Guess that is why they favour crimpled connections in cars and trucks.

Hallo Andreas, Your Video´s are very good. I like to watch them and hear your Swiss English . And I learn a lot of them. Maybe in the Futures you can make a Video how to handle a 3D Printer. I mean please show us how the software works. As I know it is not so easy to handle this 3D Software if you are a Newbe. And if you want make a Tutorial of all the things to know.
Keep on with your nice Works.
Best Regards
Jürgen
Thanks for the compliment. I made some videos about 3D printing, and I have no further plans on that. What would be your interest in addition to my existing videos?
If it is concerning 3D construction, a video would be of no use because I use a very expensive professional tool, which is not commonly used by Hobbyists.
Bis auf den Sekundenkleber bin ich recht ähnlich ausgestattet :-) BTW: das Problem mit verzinnten Kabelenden ist ein Fließen des Materials. Im Laufe der Zeit gibt das Zinn immer mehr nach und die Verbindung wird unsicher. Einen 3D Drucker habe ich auch (noch?) nicht. Ich bin noch in der Phase, wo sie mig magisch anziehen und ich sie auf Messen umkreise und darüber nachdenke, was ich damit machen würde, aber ich bin mir noch nicht sicher... außerdem brauche ich dann einen zusätzlichen Tisch.
Ein 3D-Drucker ist wirklich nützlich...
In the transistor tester can you insert a component into any terminal?
And does it work also for TRIACs?
And can you test also some DIP ICs?
mark 1. It has only 3 leads. They are connected multiple times to the socket.
2. I have no triac, so I cannot test it.
3. No, only transistors (all kinds of). Also no voltage regulators
Thanks for your reply.
1. But can you put any transistor terminal in leads 1-2-3 (without specific placements) and it automatically recognizes it?
3. Transistors but also diodes, resistors, capacitors and inductors. Correct?
mark yes
thanks!
Hello,
I received it today and I like it a lot.
I noticed that an N-channel mosfet is not properly recognized (only two diodes/junctions are shown).
I also tried a few inductors, but I am not sure about the measurements.
I will do some more tests.
step drill is a must for cutting holes in sheet metal.
ms3bani Thanks for the comment. I use it more for plastic because I do not use sheet metal often.
I use the step drill for Steel project enclosures as well. Works great as long as you don't run the R.P.M.s too high.
Thanks for the tip. I never had the balls to do tat :-)
can those terminals be soldered to through hole holes? i keep running into issues where i end up breaking solid core before im ready to do something like hot glue for stain relief and getting stranded through the hole isnt always pleasant. im sure some of that is wrong gauge wire, and or I should have a nice large pad to solder a stranded to...but life isnt perfect it would be great if this was a solution. It wouldnt be for a final version...more of a rugged prototype. maybe i need to just invest in a non ebay/china bread board. I've heard quality is everything but so far they just piss me off when time is wasted for a loose connection
Depends on the size of your pad and hole on the PCB. I see no advantage over just wiring the wire into the hole.
Andreas Spiess I always end up with a situation like only stranded wire and a size too large ...so then I end up with stray strands trying to reach the next hole. With my luck 5hats usually 5v on a 3v tolerant pin
For that purpose they might be ok
Andreas Spiess can u recommend a supplier of Chinese thumbs? I've heard the 6 year old model makes very small, precise and efficient twists for almost no cost...just can't seem to find an eBay seller 😂
I believe, in a older video you annouced to show small osciloscopes, thats my idea for another video ...
CaroMan Yes, you are right. I have to do this in the next future.
Andrea's. I am a fan of your videos. I tried the banggood link and it gave me a 404 error.
Since this is an old video it is possible they changed their products. For example, Bangood does no more sell "brother" labels...
What does" SMD-Dip Platinen" mean?
It means: SMD-DIP circuit boards
Thank you for the translation!
Tinning wire and then putting them into "block-connectors" is also a BIG no-no as the solder cold flows! - You will have bad connections over time.
I know, but I did it! This is, why I bought the ferrules
danke, für den link mit der crimp-zange! werde mal ali bemühen ... :-) ( das original ist ja heftig teurer und für privat reicht wohl das model :-) )
Bitte, gern geschehen. Macht nicht exakt quadratische Resultate, aber sie funktionieren...
looks like the wire strippers are these:
www.aliexpress.com/item/20-30-AWG-160mm-SK7-Stainless-Steel-Cable-Decrustation-Plier-Wire-Stripper/32797302290.html
they have 3 "colors" that really just change wire gauge. the middle one looks exactly like the one in the video. same measurements, same design, same lettering.
there are a few _very_ similar ones (also on ebay), but these are the only ones where everything is identical.
I do not know if the quality of the different suppliers is very different. I just bought one...
I watch your Video but never I see any add in your Video Does you didn't enable adsense?
If you do not use ad blockers, you have to ask Google why they do not show ads to you. I cannot influence that
You can even update the firmware of those transistor testers to get more features and to get it to recognize more/different parts: www.mikrocontroller.net/articles/AVR_Transistortester
Thank you for the link. This is a very interesting project!
Where do you live?
In Switzerland
What are Experimentierplatinen?
Maybe you google and you get the pictures. Easier than to describe it here
@@AndreasSpiess Hi Andreas danke, dass du mir geantwortet hast aber ich wollte nur wissen ob noch andere Zuschauer wissen was Experimentierplatinen sind!
Ich denke schon. Zumindest auf diesem Kanal findest du viele ( auch alte) Ingeneure
Looks like Banggood aren't selling the compatible tapes any more
Not good for us. Luckily I still have a few ;-)
sorry, das ich es hier frage... habe mir gerade film nummer 12 angesehen :-) da sagt du das du was zu einer wiegezelle machen wirst ... ich finde den film nicht :-( ... kannst du mir die nummer sagen.
danke.
Norbert Hartmann Die findest du leider immer noch in meinen "Projektboxen" :-)
ok, dann werde ich mal schauen wenn meine "testwaage" ankommt :-) kann sein das ich dann deine kenntnisse im auffinden von produkten brauche - ich suche eine pumpe für zähe flüssigkeiten - hier honig .... aber bezahlbar!!!
ein schönes wochenende.
Ich habe gehört, dass sich Augerpumpen dafür gut eignen. Ich habe mir eine keine gekauft, um (dickflüssigen) Lötzinn in kleinen Dosen auf der Leiterplatte zu dispensen. Die gibts auch grösser. Einfach googeln. Hab das Prinzip auch schon in Kläranlagen gesehen, und da hat es ja auch dickflüssige Kompenenten...
Liked the video and wanted to support by buying through the links. But aliexpress has painfully bad and unprofessional e-commerce. After a few unsuccessful tries to give them money I abandoned. Not good enough in today’s world. Try linking to Amazon. It works. I’ll see if I can support you on Patreon. Keep producing for us!
I have a few thousand orders with AliExpress. Nearly no complaits. Amazon does not stock most products I need :-(
You should never solder terminal wires, if you don't have crimps just use the naked wire without solder
You are right. Now I usually use crimps
I guess that your computer is super power so you can running so many web tabs at 10:05
I do not know if this needs power. But it needs a decent display :-)
And if you need to strip a really thin wire: ruclips.net/video/n5o2drU65UM/видео.html
Thanks for the tip! And for the AWG10 wires, I take the torch of my video #77 :-)
10:13... The ending turned porno....
:-))
Aderendhülsen sind im Gegensatz zum Verzinnen in der Industrie auch die erlaubte Methode :-)
Verzinnte Leitungen drücken sich über die Zeit ein und können aus Schraubklemmen rutschen, Aderendhülsen verformen sich (angeblich) nur einmal beim Einschrauben. Käfigzugklemmen stellen sich quasi nach, bzw. gehen so sanft mit den Leitungen um, dass sich nichts verformt
Und sie sehen noch besser aus. Danke für die Info.
