Review: PCB Service of PCBWay.com

Posted on 22. August 2020 by Fab

It’s been a while since PCBWay asked me to test their PCB manufacturing service. This was a perfect opportunity to have the circuit board for the “mobileSupply” project manufactured . […]

I hope this is still compliant with the rules when I present the results of the #solderingSunday on the #microscopeMonday? 😌 You can see the assembly and soldering of the WS2812 LEDs on the front of the boards of my still secret project. :)⁣
The boards were provided by @pcbway. 😍⁣

After I was able to fix a small error in the programming circuit, the test of the LED matrix was still pending. For this I soldered the LED matrix of 100 SK6812 3535 LEDs on another board and then connected it to the board on which the ESP32 Wrover is soldered via a connector. Later everything will be installed on one circuit board. 🙃 I have already tested the remaining components on a separate PCB. With the next iteration, the pxlBlck_multiPCB should (hopefully) be error-free. 🙂⁣

I wasn't in the mood the last days to work on the #pcknplc machine but decided to work on the automatic tip changing today. These can be changed by defining four positions. As soon as a change is necessary, these are approached one after the other and the this way the desired tip is mounted on the pick head. 🙃 This way, the machine can change the appropriate tip depending on the component size and then pick up the component it should place on thr PCB. 😎⁣

(... Continuation of my previous post) So the stepper motor still didn't have enough torque. No problem, I thought, a little more motor current should fix this. So I turned the potentiometer for setting the motor current on the A4988 stepper motor driver to the maximum position. The reference voltage "Vref" is set with this potentiometer. In combination with the resistor "Rs" built into the stepper motor driver (and the now set reference voltage Vref = 0.8V), the following motor current results according to the data sheet of the driver: Imtr = Vref / (8 * Rs) At this point I also noticed that the value 0.1Ohm was installed on the stepper motor for the "Rs" resistor. Sufficient for most stepper motors. Unfortunately I wanted to run my newly installed stepper motor with its maximum current of 1.7A. With this "Rs" value, however, a maximum of only 1A can be set. In order to extend the setting range for the motor current up to 2A, for example, the value for Rs must decrease to 0.05Ohm. Usually not a problem. Unfortunately I didn't have the 0402 SMD resistor there. But: I had an old defective motor driver with the same values. So if I were to unsolder the Rs from the defective motor driver and solder it in parallel to the Rs in the intact motor driver, the total resistance of the two Rs connected in parallel would have to reduce to 0.05Ohm. That's the plan. You can see the conversion in the video. And why that should still not lead me to my goal, you will see in the next post. 🙂 ⁣

This section of the pxlBlck_multiPCB is literally self-explaining. 😂 A large part of the new functionality is now running. I was very curious about the MAX98357 I2S Class D amplifier. This is connected to the ESP32 via I2S. MP3s can be played from the inserted micro SD card, web radio can be streamed or text can be read aloud. The goal is that the pxlBlcks will soon also be able to play audio data. For example, you could be informed acoustically about events in the SmartHome. Alternatively, you could also play a web radio stream in this way. 🙃⁣ The PCB is made by @pcbway. 😍

Complete build guide available here: https://nerdiy.de/en/howto-pxlblck-pxlblck_cassettelamp-aufbauen/

In the last few days I have finished the article for the pxlBlck_CassetteLamp. This lamp is a little homage to the time when music was not on a 512GB micro SD card but in the form of audio cassettes. I thought it was a shame to let the cassettes gather dust in a box in the basement and made a small decorative lamp out of them. With the help of a few # WS2812 LEDs, an ESP8266 and an old USB power supply unit, the pxlBlck_CassetteLamp can be built. With the help of the #pxlBlck plug-in, the lamp also gets a few SmartHome functions and can thus also inform about events in your SmartHome. In addition to the setting options via WiFi, the lamp can also be adjusted with the help of a pen - just as the cassette tape salad used to be wound up. You can find the build instructions including a list of needed materials and detailed pictures on my blog at Nerdiy.de. 🙃

Here is a short summary of the structure of the bracket for the new controller board of my #pcknplc machine. The board is mounted on the base plate using a 3D printed bracket, official_ruthex threaded inserts and a few screws. 🙃

In the meantime I have finished the holder for the tips of the #pcknplc machine. There is space for up to eight tips. Each individual tip is pulled into the correct end position by a small magnet. I've tried different versions and especially experimented with the distance between the magnets and the tips. There should be enough force on the tips to pull them into the correct position. At the same time, they should not be magnetized too much. In this way, I want to avoid that the potentially magnetized tips will attract components when they are not supposed to. 🙃 The holder is required later - depending on the component size - to automatically attach the correct tip to the pick head. 🙃⁣

It doesn't look like much, but it was quite a bit of work. 😂 The controller boards I have used so far are all based on the Marlin firmware. The controller board of my #pcknplc machine is based on the smoothieware. The latter uses a completely different concept for configuration. A couple of timing belts have suffered a bit, but now it's moving. 😍 🙃
