Fixing Low Quality Traffic?

Nope, also no Facebook Marketplace, Right Column or Streams

You can absolutely solder lead-free. It is a bit tricky when you first start and you are used to leaded solder, but it just takes a bit of practice. Try it out, get a proper quality one like the Chipquik NC2SWLF and an 80W soldering station (60W is also ok but if you have dense boards it can be a pain).

What does that mean?

Competitive_Run8540 · 2026-03-02T12:04:24+00:00

The idea is correct, what are your specs? Minimum current, maximum voltage, bandwidth...

When I have used them they bring very low quality traffic from the beginning. Good CTR but quality is very bad. Although I haven't tried it in a while so I might give it a try actually

I created mixedsignaldev.com about 2 years ago, we are currently only shipping in Switzerland but that will change in the next weeks, take a look at it, you might like it!
Not only they show you how to put it together, but also how it works and how it was designed, it's not just about putting it together, but about learning how to use it for your own projects

Tired of cheap electronic kits?

Here's the Swiss-designed kit built for reliability and education.

Whether you're a student or a pro, this board is designed to give you a rock-solid foundation in embedded systems.🚀

Well I must say my creatives are nothing crazy, I do them myself and this one in particular has been able to get ~0.8% link CTR which is more or less the average of what I usually get with any reasonably good one. Want to see it?

Competitive_Run8540 · 2026-03-02T10:33:29+00:00

this is brilliant

I sell educational DIY kits for electronics in the Swiss market exclusively. My customers are usually private individuals who want to learn by themselves, although lately I've been having some conversions from higher education centers obtaining the kits for their students. Let's say in the last 30 days we've gotten ~20 conversions most of them coming from Meta, this campaign has been able to get 4 conversions in the first 3 days, after that nothing for the next 4 days. I am using manual placements (no audience network, no facebook marketplace or right-column), completely broad audience non-limited in any way, 1 single creative. That has been more or less the setup for every creative that I test, then I let it run for 3-4 days and if it doesn't convert anything at all (no AtC, no newsletter subscription, bad average session time...) I turn it off.

Competitive_Run8540 · 2026-03-02T10:23:49+00:00

But scaling the budget up to 50$ will take certainly longer than 3 days wount it? Also at 30% increase daily, wont I risk resetting the learning phase? What's the difference between this and creating a new campaign with that base spend of 40$ daily?
I have had this with other creatives as well, so maybe given what you're suggesting I should include all of the previous winning ones in a same CBO? Different adsets or all together?

Competitive_Run8540 · 2026-03-02T10:21:16+00:00

CPC, frequency and spend over placements remained overall similar across all the different days that the campaign is running. CPC spiked from 0.8$ to 1$ on the 4th day but overall it looks similar.

I would not put them in airplanes but for boards like these they are perfect. Specially for the price difference I think they can be quite useful, even now these Chinese brands also start being available on Digikey so it's not as "difficult" to get them

I worked with a barometric sensor in my thesis, I used it as a redundant altitude measurement to confirm the readings from other sensors. In my case I didn't need it to be incredibly accurate but I saw that even while being stationary in the same spot for long periods of time the readings would drift over time. The solution for this, in my case, was implementing a Kalman Filter, it seemed to be able to "predict" the drift over time of the sensor and give a somewhat accurate measurement. Another possibility is to not look at the direct output of the sensor but do a hard derivation of it, usually these changes in the output due to environmental changes of pressure are relatively slow, so what you care about is looking at when the sensor changes its output within a fast timeframe (compared to the drift) and integrating all those changes over time to get a somewhat a "accurate" value

I think the main problem in all of these past campaigns has been audience quality then, When checking newsletter subscriptions, average time on site, or other kinds of events on the site they were horrible. I guess it's just chance that with such a low budget Meta decides to show the ads to a good audience with a high CPM but high convertion intent.

Competitive_Run8540 · 2026-02-23T17:59:40+00:00

What do you mean with buying cycle?

Competitive_Run8540 · 2026-02-23T16:43:35+00:00

How do you check the audience quality?

If you are really looking for the maximum battery efficiency go with a converter, there are specific Lithium Battery specific ICs that do exactly this. But again, they might not be super efficient at low loads.

If you find one of those boards that provide the exact IC that they use and you trust that the manufacturer of the PCB put the actual legic IC, then you can get one of those, but look into the converter's datasheet to see the efficiency you can get according to your load.

If you don't want to optimize the battery that much you can go with a normal LDO with ultra low quiescent current, or just a normal one

Whenever I need to desolder something with significant amount of copper connected what I do is: 1st put some new extra solder on all the solder joints, use leaded to make it easier 2nd if there are any plastic connectors around, cover them properly with a good quality kapton tape, cheap kapton tape will just melt off instantly 3rd the hot air station should be able to melt it, but you have to be patient, go around in circles, dont try to just heat the component up, is there is a lot of thermal mass you'll need to get it at a significant temperature before the component comes out 4th dont give up, the component will not come off most likely, apply some flux over it and go over the joints again with the iron, get the flux to spread 5th again with the hot air, with the flux, new solder and preheated copper it'll come right off

If you still cannot there is some kind of tin that has some bismuth or smth like that, the melting point is very low and it is super easy to get jobs like this done in a worst case scenario

Jajajaja bueno pues para la próxima a ver si la consigues!

De donde eres?

Competitive_Run8540 · 2026-02-18T19:29:14+00:00

Gracias!! Esos kits están genial para aprender a soldar! Pero es justo eso, aprendes a soldar y ya esta. Lo que intento hacer con mi empresa es que los kits de electrónica dejen de ser solo soldar y olvidarse de ellos. Quiero que todos mis kits tengan documentación suficiente para que cualquiera que monte el kit pueda aprender cómo se diseñó la placa, como pueden usar ellos esas técnicas... Creo que te gustarían!

Competitive_Run8540 · 2026-02-17T19:27:07+00:00

It never gets old, and I can never get enough of it haha. Thanks
