The first test for our WLED board codename "Sparkle Motion" 🌈💖💡 … 🐇⏳🌌

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED

We are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C. We'll also do an Arduino IDE board definition in case folks want to use it as a generic ESP32-to-LED-driver board. We're calling the board "Sparkle Motion" for now, but if you have other naming ideas, let us know - if we pick your name, you get a free board

Sign up, coming soon.

LED Driver Failure Symptoms

LED driver failure can manifest in various symptoms, which can differ based on the type of failure and the specific LED driver design. Here are some common symptoms of LED driver failure: LEDs not illuminating: The most apparent symptom is when the LEDs connected to the driver do not light up at all. Flickering or flashing LEDs: A failing LED driver might cause the connected LEDs to flicker or flash, which can be intermittent or continuous. Dimming or reduced brightness: The LEDs might appear dimmer than usual or not reach their full brightness potential. Inconsistent light output: The LEDs may exhibit uneven or inconsistent lighting across the array or fixture. Overheating: A malfunctioning LED driver might become excessively hot, and you can feel the heat when you touch it. Burnt smell or visible damage: In some cases, you may notice a burnt smell coming from the driver, or there might be visible damage to components such as burnt spots, discoloration, or melted parts. Noise or humming: A failing LED driver can sometimes generate electrical noise or humming sounds. Interference with other devices: A faulty LED driver might cause interference with other electronic devices or create noise on radio frequencies. Power surges or fluctuations: LED driver failure can lead to unexpected power surges or unstable power output. Inability to control dimming or color temperature: Dimmable or color-adjustable LED fixtures may lose their ability to adjust brightness or color temperature when the driver is failing. It's essential to note that some symptoms might also be caused by other factors, such as faulty LED bulbs, poor connections, or problems with the electrical supply. Therefore, it's crucial to troubleshoot and identify the root cause of the issue correctly. If you suspect that the LED driver is the problem, you can try replacing it with a known working driver of the same specification to see if the issues persist. Read the full article

RA8875 Breakout Board gets a revision plus SPI tri-state fix 🔧🔌🔄

The RA8875 is a nifty chip that can do SPI to 24-bit TTL display, up to 800x480! https://www.adafruit.com/product/1590 this breakout is an older design and with many parts no longer available, we had to do a respin to change the backlight driver from a FAN5333 to another high-output constant-current LED string driver https://blog.adafruit.com/2022/08/02/the-great-search-white-led-strand-backlight-constant-current-driver-fan5333-replacement-thegreatsearch-digikey-adafruit/ and while we were there we also updated the MISO pin to be tristate-d via a 74AHC1G125 so that you can share the SPI port with other chips - that was a request from over a decade ago that linged on my todo list. but it's done now :)

Capacitor impedance : capacitance 가 작아질 수록  capacitive reactance가 커져 임피던스가 커진다. 임피던가 커지면 오움의 법칙에 따라 전류량이 적어진다.

220V에서 LED에 걸린 전압의 나머지가 C1에 걸린다.

로드(LED) 걸리는 전압은 C1 과 R1에서 전류가 constant ��다면 일정해진다.

테스트 한것 중에는 100uF 제일 전류가 적게 흐르고 전압도 34V로 내려간다.

4.7uF electrolytic capacitor는 전류도 179mA 까지 올라가고 전압도 41V까지 올라간다. Capacitor에 열이 발생해서 사용할 수 없다.

The voltage at the load will remain constant so long as current out (IOUT) is less than or equal to current in (IIN). IIN is limited by R1 and the reactance of C1.

R1 limits inrush current. The value of R1 is chosen so that it does not dissipate too much power, yet is large enough to limit inrush current.
