How to make a bass crossover?
Today, I present a self-made bass crossover for everyone. Although the material is not much and simple, the bass effect is extremely strong.
Above picture below
Circuit diagram,
Because the circuit needs 2 electrodeless capacitors, I don't have electrodeless capacitors, so I use 4 50v10uf capacitors in series instead of electrodeless capacitors.
Hole board.
A mold for winding coils.
Because I only took pictures after the things were done, there was no picture of winding the coil. The winding method of the coil was 20 turns from the inside to the outside, 5 layers, and the middle was reinforced with 502. After winding, remove the layer of film and coil on the glue bottle, tear off the film, and the coil will be born. The wiring of the coil is an external MP3 pin, internally connected with a capacitor and a speaker.

Nervos is an ambitious newcomer on the crypto market and Changelly has long watched it with interest. The project attracted the attention of investors and developers since its purpose is not to launch another cryptocurrency in the ecosystem. Nervos is a simple connecting database between any blockchains.
Nervos was launched in November 2019 by Nervos Network and aims to fix issues that plague both Bitcoin and Ethereum. Among them are scalability and value differences. To fix them, the Nervos team wants to implement effective scalability and raise the cost of their token by hosting other cryptocurrencies on their blockchain. Nervos supports smart contracts and is censorship-resistant. CKB is a native token of the Nervos network. It scales with the value of other assets stored on the network: the more cryptos and tokens are there, the more valuable CKB becomes. This means that this token will continue raising its value the more attention and assets it attracts. Add to that the support of smart contracts, and you have a nice crypto bridge between different blockchains. Which is exactly what makes it so attractive for both crypto enthusiasts and investors.
