Working on the gallery functionality a bit today. I can now navigate through the gallery and delete poor quality results....not that that ever happens 😅. There is also a hard to see index counter in the bottom right. Though I know the UI needs work, I'm excited to see the functionality coming along. Be sure to follow for more updates about the project.

A level shifter just for pixels 🔌✨💡

After noodling with some WS2811s and TM1814, we really wish we had a board that would level-shift our NeoPixel signals from 3V to 5V or give us an inverted data line. So, we designed this board. It uses an AP3602

https://www.digikey.com/en/products/detail/diodes-incorporated/AP3602AKTR-G1/5305823

charge pump to give a clean 5V reference voltage from 3~5V. A 74HCT2G34

https://www.digikey.com/en/products/detail/nexperia-usa-inc/74HCT2G34GW-125/1300830

shifts two signals - we call them DAT and CLK, but it could be anything really - to 5V from 1.8~5V. Finally there's an 74LVC1G04

https://www.digikey.com/en/products/detail/texas-instruments/SN74LVC1G04DBVR/385716

inverted data output line for TM1814 and other weird chips. Terminal blocks on either side make this a no-solder board. There's also a single disableable 1.5mm NeoPixel on the DAT line for testing the WS281x signal coming through OK. Coming soon.

Take you to know the LED power supply

An LED power supply, also known as an LED driver, is a vital component in LED lighting systems that transforms mains electricity (AC) into direct current (DC) to drive LED lamp beads.

Key functions of LED drivers encompass:

Conversion of AC to DC.

Supplying the specific current and voltage needed by lamps.

Offering circuit safety protection for lamps.

Processing electromagnetic compatibility and filtration.

Facilitating other intelligent controls.

Driver-On-Board (DOB) technology integrates the power supply components and light source into the aluminum substrate. This approach, involving switching or linear power supplies, has been increasingly adopted for indoor lighting solutions due to its cost-effectiveness without compromising product quality.

LED power supplies can be classified in multiple ways:

By Output Type:

Constant current power supply: Delivers a steady current with a varying voltage within a set range according to the load resistance.

Constant voltage power supply: Provides a fixed voltage with the output current adjusting based on the load.

By Installation Location:

Built-in power supply: Installed within the lamp cavity, requiring insulation measures if the lamp has a metal shell.

External power supply: Positioned outside the lamp, requires insulation casing and waterproofing for outdoor use.

By Drive Type:

Linear Drive: Simple and direct, without high-frequency switching action, eliminating the need for magnetic components like transformers and electrolytic capacitors in some cases.

Switch Drive: Offers accurate current control and high efficiency, classified into two methods: buck type (for higher power supply voltage than LED terminal voltage or parallel LED driving) and boost type (for lower power supply voltage than LED terminal voltage or series LED driving).

By Isolation:

Isolated Power: Conversion involves an "Electrical-Magnetic-Electrical" process, using a transformer to step down the voltage before rectifying it into a DC output.

Non-isolated power supply: Conversion follows an "electrical-electrical" process, reducing the voltage through components such as inductors before transforming it into a DC output.
