@realwillreil Oh, that’s neat—the USB-C soldering is clean with the hot plate. I need one too! Does this hot plate support custom profiles where the temperature reaches a certain value at a specific time after it cool down?

The case is finally printed. I love the glowing effect by putting the LED behind 1 mm of PLA. It shows historical measurements plus the current hour. There are still some improvements to be done on the casing. The ENS161 from #sciosense works very well after a couple of days of auto-calibration.

Flux and glue are the enemies and make false readings; this super sensitive stuff requires cleaning the board and ensuring no IPA gets on the sensor, otherwise it’s ruined.

What a day! Received my first made PCB and it works!

Partially assembled by @JLCPCB. The quality is perfect.

I soldered the ENS160 and the ENS210 without a stencil. The temp sensor was super hard, but everything works perfectly. Soldering the ESP32 was the easy part.

Preparing videos for the soldering part coming soon.

@realwillreil It's hard to find competitive advantages to build in Canada. Labor and shipping are expensive, so the final product will cost too much to be competitive worldwide.

[Chakib @chachacodes]

@23_ @realwillreil Logistics is about density and volumes! Canada is low on both of them.

[Chakib @chachacodes]

@realwillreil BC ? Beautiful

[Chakib @chachacodes]

@realwillreil Now it's a really schizo board 😁. A beautiful working board. Maybe for the next one, you should just mix SMD and through-hole components

[Chakib @chachacodes]

@MattiaFiumara From AliExpress? I have one and get too much reflection when flux is on the board. Sometimes I disable the ring LED to see what I am doing. Have you noticed the same issue?

[Chakib @chachacodes]

@realwillreil 513 smd resistor are for cc1 cc2 ? Because 5.1k is 512 (5100) not 513 (51000)

[Chakib @chachacodes]

@realwillreil :/ know this feeling maybe it’s one small thing miss soldered, do you have a 5v output from the usbc ? The 5.1k resistor seems missing soldered on the left

[Chakib @chachacodes]

@realwillreil I have a 7-hour flight to go through, yes please.

[Chakib @chachacodes]

I'm using exactly this 5V VCC and signal input straight from the ESP32. I've never had an issue with that and never thought I was doing something nasty haha. Glad to see that. What we should see is if the signal output from the first LED that feeds the second one is 5V or 3.3V. We need an oscilloscope for that. Do you have it?

[Chakib @chachacodes]

@realwillreil @JLCPCB Thankyou @realwillreil thanks to you motivating people with your tweets and discoveries

[Chakib @chachacodes]

@IDV_FPV waiting for you man 😀 we should make a context including @realwillreil and @i2cjak as a judge ! We need to find a prize 🏆

Streaming all data through a USB-C cable and notifications through Bluetooth.

[Chakib @chachacodes]

Sensing the air and indicating air quality using the ring LED, storing historical data on the embedded EPROM.

[Chakib @chachacodes]

@IDV_FPV @HQ_NextPCB PCBA, JLCPCB shipped it fast, but the local carrier takes too much time.

[Chakib @chachacodes]

@realwillreil When it works hhh

[Chakib @chachacodes]

@realwillreil Best feeling in the world
