Electronics Quick Tip: Read illegible IC Markings
In this little quick tip I'll show you the absolute best and bulletproof trick to make illegible IC markings readable from a distance.
Forget the spit finger, forget light at funny angles, after you tried this you'll even toss your complex polarised light setup.
Sorry for the painful shaky cam, I realised too late it was silly to mount the camera arm to the same desk I'm working on...

3D Printer Conductive Probe Bed Mesh Run
มุมมอง 932 หลายเดือนก่อน
This shows an entire bed mesh sequence on my 3D printer using a conductive bed probing setup. I use a normal PEI coated spring steel print bed, but between it and the magnetic pad sits a stainless thin steel plate. This plate is connected to a GPIO pin on the raspberry that runs the printer. The nozzle of the printer is connected to ground in the video you can see the ground wire on the top of ...

Custom stick-on support for super flexible TPU
มุมมอง 402 หลายเดือนก่อน
This video demonstrates how I use a custom support structure printed in PLA to support difficult geometry printed in super flexible TPU. The results and post processing can be seen here th-cam.com/video/DpN4SG2uwKs/w-d-xo.html
My project is confusing the ever living shit out of me.

Smooth surface supports using kapton tape

This shows my first attempt of using a custom flat support structure and kapton tape to create a smooth underside without annoying support cleanup. The results can be seen here th-cam.com/video/j0o6ChY6slg/w-d-xo.html

E-Ink "burn in" experiment
มุมมอง 4182 ปีที่แล้ว
Little experiment to thee if stuck or "burnt in" pixels in an e-ink display can be fixed by heat and pressure. Here I run some simple g-code to move a roller bearing back and forth across the panel, applying some pressure from the 3D printed bearing-bolder that features a little leaf spiring. The bed is heated to 50°C and I have the panel constantly switch between full black and full white in v...
Really good, thank you
Nice . .A piece of chalk (like the ones used on classroom blackboards/chalkboards) also work very well. They are much easier to clean up, but your paint marker seems to give a bit better contrast.
Oh, that's a good idea too! And tbf, it doesn't need to be permanent
thank you ,it is working
Nice.
I think I have a paint marker around here somewhere.. going to have to try this when I get back to projects.
Few months back I bought a paint marker again after not needing one for very long. For about a week basically anything in my flat was paint-marker'd and after I ran out of stuff I reached into my IC drawer and a new idea was born :D
Another method that I saw on eevBlog is scotch tape.
Oh, how does that work?
Swanky!
I have also been doing a conductive nozzle probe for my printer, I'll be uploading a video soon. That's not your actual print surface, is it? My understanding is that bare metal is a bear to stick prints to.
It isn't. I've tried printing on the bare steel surface, but _surprise_ it doesn't stick well. There is actually a video on my channel where I tried it with surprisingly good results. th-cam.com/video/p3OTS_WiOpQ/w-d-xo.html I'd be super interested to see your setup. So far I've not seen stuff like that. I'm not the biggest fan, but only having a 120x120 print bed means any probe offset leave large portions of the bed unprobed

Gibts für den lüfterkanal ein stl? 👀
Sorry für die späte Antwort :D Das Teil bzw. die Halterung ist ziemlich auf diesen Drucker abgestimmt. Aber ich kann Dir gerne was hochladen, wenn Du Dir das entsprechend anpasst
@juminal1347 sehr gerne 🙏🏼

Ia that 2 axial fans screwed together as a part cooler?
No, that's a fan from an old server PSU :D Needless to say it's deafeningly loud! I'm using a different setup by now.
.... hmmm... schön.... so schön "Kommentarlos"... was für ein Material? Warum Edelstahl? Vorteile? Nachteile? wie ist es fest gemacht?... usw usw usw.... ein par Infos dazu wären ganz nett.
Witzig. Ich nutz das hier hauptsächlich um Videos zu dumpen um sie woanders zu verlinken. YT kam scheinbar auf die Idee dises dezent zu "pushen" Ich weiß nicht 100% was für'n Metall das ist. Es ist Edelstahl aber nicht rein, es ist dezent magnetisch und ist auch per Magnet befestigt, also statt PEI Platte. Gedruckt ist PLA. Vorteile... Absolut keine. Nachteile... Schlechte Haftung 😂 Ich benutze die Spitze und diese Metallplatte für's levelling under meshing. Und ich wollte mal testen ob ich die Druckplatte auch weglassen kann. Antwort: nein. Ich versuche mal dran zu denken heute Abend ein bisschen Beschreibung zu texten
Ist Ben ferritisches Edelstahl würde ich schätzen verspiegelt poliert. Druckt sich normal Bombe drauf selbst Petg hält auf sowas normal wie auf ner glasplatte. Verschleißt halt nur nicht und es können keine Splitter raus brechen. Drucke seit mehreren Jahren nur noch auf verschieden behandelte Metallplatten und die pei Platten stehen sich die Beine in Bauch. Warum der Video Ersteller nun sagt es hält sogut wie gar nicht kann ich nicht sagen. Bei mir kommt pla da sogar noch mit nem Knack runter. Trotzdem schön zu sehen das auch andere mal was ausprobieren. 😊
Auf bloßem Stahl? Komisch... Bei mir hält da nix. Anrauen ist eine gute Idee, das probier ich mal aus. Ich drucke auf einer magnetischen PEI Platte, habe aber schon lange zwischen dem Magnetpad und der Druckplatte diese dünne Stahlplatte. Die Druckerdüse ist geerdet und die Platte an einen GPIO am Pi angeschlossen. Dieses Setup benutze ich zum bed levelling. Funktioniert ziemlich gut und ich hab keine x/y offsets um die ich mich sorgen muss :D Ich probiere gerne mal etwas schrägen Kram mit meinem Drucker aus, gerade auch wenn es um schwierige suppirtsituationen geht
Hier kannst Du Dir mal anschauen was ich meine th-cam.com/video/x8ZdceU5x-I/w-d-xo.html
why stainless ?
It's a silly test. I use the stainless plate and the nozzle for conductive probing. It's used for levelling and meshing. I was thinking maybe I could leave the PEI sheet and print directly on the metal plate. It's a total failure and almost repelled the PLA I printed on it. It stuck just enough for this two layer plate I tested with. A regular print detached immediately
@@juminal1347 Conductive probing like when you do PCB milling? if in that case try aluminum it has better heat transfer than stainless but if you still want to use stainless maybe rough up the surface a little like a pei sheet or go another way around and make it ultra smooth like a glass bed.
If you get your eyes to focus right can view in stereo vision 😋
very nice video work as well.
also very nice.
nice.
Hard to tell from the video - do the pixels look any less.. stück after the experiment?
I was actually massaging the top half of the bar code to make changes blatantly obvious. No luck. Running the whole thing heated for over an hour didn't have any effect.
