Since it'll take some time for the PCBs to arrive, I decided to make a #prototype on #perfboard. It works fine, and I can test my programs using it. Turns out an #ATtiny814 is good enough for the task.
The #WS2812B #SMD #LEDs are very bright, though, and reducing brightness also reduces the possible color range.
The different color shadings are not very distinguishable, yet. I might have to adjust the color palette.

the back side of the perfboard prototype. there are lots of ceramic capacitors arranged in a heart shape. a few jumper wires are visible, with the insulation red, black, white, and without.

the front side of the perfboard prototype. there are 34 WS2812B SMD LEDs, arranged in a heart shape.

First board went well. I’m going to make a batch of 3 more now (all I have the components for today). #smd #electronics #pcb

Components placed. It is now in the oven. #SMD

#nerdalert #smd #helpneeded #electronics #fixer #repair Has anyone got a steer on what this is, I’m drawing a blank. It’s on the power supply board for a heating system. The DF04S that feeds it is blown, so is a 78M05 nearby (as well as 3 opto isolators). Suspect a lightning strike.

My first step: #hotairrework #smd

Trying to decide if being #lazy is acceptable, or if I should do the job properly.

I have a #pcb with a 100 Ω #SMD #resistor already soldered to it, but need to replace it with something around (but not under) 27 Ω.

I could attempt to desolder the original resistor (but I don't have a heat gun/plate, so would have to do it with a soldering iron) and replace it with the correct value; OR I could solder a 39 Ω resistor on top of it, giving the equivalent resistance of ~28 Ω.

But is the lazy approach actually ok in practice? Should I just do it properly? 😬

Mir gings eigentlich nicht um das lernen ansich.

Eher die Abschreckung das #SMD und somit #elektronik teuer ist.

Wer hat schon ein Mikroskop etc dafür zu Hause?

Auch die #Platinen für #SMD gibt es nicht wirklich als universell.

Alleine wie man diese herstellt / bestellt ist ein eigener Kurs.

Lochraster, ein bißchen Draht für ein bißchen #BlinkiBlinki ist wesentlich günstiger für den lernenden Anfänger.

@karlsruhe

Beim dritten mal löten gleich #SMD halte ich für gewagt.

I'm doing weird stuff again. I'm soldering USB hubs on flex PCBs.

By accident, I ordered exactly as many 0.1uF 0402 size capacitors that I needed. BAD idea 😅

Well, I guess I'll finish it next week, after the extra capacitors arrive. 🤷🏼‍♂️

Hey Fedi!
I have a cheap logic analyzer that I want to use on an #SMD #esp32s3, the difficulty is to make sure the probes stays in place while doing aquisitions. For now I use dupont wires, but it's obviously not going well.
What is the kind of probes that should be used in those cases?

Boost welcome :)

Alright, electrical engineer friends... I'm trying to figure out why my drawing tablet's display broke. I was able to pry it open, and found a cracked diode, but I can't identify it. A bit of searching makes me think it's a tvs diode, but I've no idea what it specifically is (or what an appropriate replacement might be). It looks like it's marked "XM", and I can't identify the logo beneath it (thought it was ST, but that doesn't match their logo)

Yeah, the PCB and the stencil I ordered from @seeedstudio arrived, and I can test the pick and place machine we've got here @hkustguangzhou @hkustgz_cma #pcb #pcbuild #pickandplace #smd #Electronics #design #dmi #hkustgz

Könnt ihr mir bitte gleich die Daumen drücken?

Gleich kommt der #SMD der neuen #Krankenkasse um mich im Rahmen der #Pflegestufe zu begutachten. Meine Nerven sind zum reißen angespannt.

Hoffe dass ich wenigstens heute von einer #Panikattacke verschont bleibe.
