The materials to be prepared are as follows:
A resistor of 4~8 ohm 0.5~0.7w, (depending on the battery power, the larger the battery power, the smaller the resistance value of the resistor) It is best not to make the resistance power too large, otherwise the heating will be slow Say~~
A crystal diode (Well, it seems that there is a resistor, so you don’t need a diode, but in order to ensure the accuracy of the title "Semiconductor heater" I posted before, let’s use a diode! Note: The diode here can be used instead of the resistor. , But the effect is not very good. The one that uses resistors is an improved version, and the one that uses diodes is the lower-level version yesterday)
A power connector, no explanation
Here we put the resistor on the fire and bake it to remove the insulating layer on the surface of the resistor. The black circle is the resistor. If you plan to use a crystal diode as the heater, then don’t bake it, just go to the last step~
After baking the resistance, note that the resistance should not be baked for a long time, otherwise ~~~~ consequences. ... .. you know
Solder the baked resistor or unbaked crystal diode to the power socket
Then solder a wire to the other side of the power socket. At this point, our heater is complete, and finally we picked up the No. 5 battery in our hand to directly energize the two wires. After that, the resistor or diode will generate considerable heat. It can be used as an electric soldering iron or firecrackers. In short, it also has many features that geeks need to find on their own. ..
These are two heaters I made. One uses a crystal diode as a heating device, and the other is made of a resistor. Here, I must reveal a secret to everyone, that is, no matter what the situation, the heater is made of resistors. , Both temperature and cost performance are better than diodes

Antenk Modular Jacks are a complete line of PCB and wire leaded jacks which are UL and CSA approved and meet all required FCC rules and regulations. Antenk offers a multitude of sizes (4P2C thru 10P10C) with styles including single, ganged and stacked versions with options of ferrite or magnetic filtering and or metal shielding. Jacks with integral LED`s,These jacks are available in thru-hole or SMT mounting.
RJ45 interface can be used to connect RJ-45 connectors. It is suitable for the network constructed by twisted pair. This port is the most common port, which is generally provided by Ethernet hub. The number of hubs we usually talk about is the number of RJ-45 ports.
RJ45 is a type of different connectors (for example: RJ11 is also a type of connector, but it is used on the telephone); there are two different ways to arrange the RJ-45 connector: one is white orange, orange, white green, blue, white blue, green, white brown, brown; the other is white green, green, white orange, blue, white blue, orange, white brown, brown; therefore, there are also wires with RJ45 connector There are two kinds: straight line and interleaved line.
The RJ-45 port of the hub can be directly connected to terminal devices such as computers and network printers, and can also be connected with other hub equipment and routers such as switches and hubs. It should be noted that when connecting to different devices, the jumper method of twisted pair cable used is different.
