The milling cutter "Fiolent MF 2-620E" is a good, convenient, lightweight and quite powerful machine, but it has a significant drawback. There is no illumination of the working area. For illumination, the following details will be required; 5 volt phone charger, 6.2 ohm resistor rated at least 0.5 watts. , 4 LEDs and a bit of wire.
Many homes have old phone chargers. Need electronic charging. Carefully open and get the board.
Remember or sketch where 220 V and 5 V were connected. and solder the wires. Next, we disassemble the machine "Fiolent MF 2-620E"
At the back of the engine, the machine has enough space, we take a board from the charger and try on.
The photo shows that there is enough space for the board.
Now about the LEDs. I applied Chinese LEDs
SMD 5730 with a power of 0.5 watts. 4 things. All of them are connected in parallel.
To limit the current, a resistance of 6.2 ohms is connected in series with them. The average current through the LED is approximately 80-90 mA. which is approximately 60% of the power. This mode increases the life of the LEDs. For installation, we cut out two strips of 15 x 20 mm in size from foil fiberglass. And soldered in pairs on the plate.
Plus and the LED housing are connected inside and minus the LEDs we solder to the narrow edge of the plate.
We check them, and then glue them on the router.
Now solder the whole circuit. The 6.2 ohm resistor is soldered to the plus of the charge and fixed. The ends of the 220 century. with charging, connect to the network cable of the router. They are connected to the button and clamped by screws. Now you can check. We turn on the network and the LEDs should light up. We lay the wires and the charging board, we fix it with a thermal gun.
Close the lid and enjoy.
P.S. In two years of operation, there were two failures. Once the resistance of 6.2 ohms from vibration broke off, another time the wire broke off near the LEDs.
With best regards, Vladimir!
