  • Hello to all users of the Electrode Forum.

    A bedside lamp is a simple device consisting of just a few elements. This one is designed to please the eye and `` create a mood '' while listening to music, it was made in the form of a tube monoblock.

    Before I get verbally lynched by users of the Electrode forum for wasting a good tube, I would like to inform you that I got the tube from a good audiophile neighbor. The damaged tube was left to him after the repair of his amplifier, which was humming mercilessly in one channel. The reason for this hum was the 6S18S tube, which has a breakdown of one filament to the cathode at 64 k?, as you can see on the measurement of a cold tube with an ohmmeter.

    I liked the lamp so visually that I decided to build something on this damaged lamp and I think I managed.

    I bought almost all the parts for the lamp construction on the Chinese AliExpress before the introduction of VAT and postage over a year ago. Some elements in excessive quantity, because that is how they were packed and sold, the price is per set.

    In total, the costs are:
    Rubber feet: 8.97 8 pcs.
    Burmester lettering: 6.85 5 pcs.
    Fender lettering: 4.80 3 pcs.
    VU meter: 13.08 1 pc.
    DC 5.5 / 2.5 jack: 2.64 2 pcs.
    Rotary switch: 12.64 1 pc.
    RGB / 10W bulb: 11.50 1 pc.
    Aluminum housing: 29.00 1 pc.
    Total: PLN 89.48



    In addition, screws, wires, spacers, a 6.3 mm jack socket, a 48 mm rubber o-ring and a power supply from an old 12 V 1.5 A router are stocks from my drawer junk.

    To illuminate the lamp, I used the module shown in the photo with parts, taken from the Chinese 10W RGB bulb. In addition, I gained a remote control, which was included with the bulb. It allows you to change the color of the backlight in the range of 16 colors plus 2 smooth color transition programs, which looks very nice on a working lamp. I desoldered the infrared receiver module from the board and placed it in a cut 6.3 mm jack socket.

    Coming back to the bulb, as you can see on the measurements, the Chinese 10 W turned out to be 6.5 W with all the LEDs on and full brightness. The minimum value is 1 watt with the red color lit and the brightness set to the minimum.

    The 6S18S lamp is housed in a thick rubber O-ring glued to the metal housing. You can easily put it on and take it out, there is no fear that it will fall out by itself.

    As a result of the diffusion of light on the glass bulb of the lamp on the wall and ceiling, nice colorful light reflections are created and create a pleasant atmosphere when listening to music. The lighting power is sufficient for this purpose and can be compared to a lit two standard candles in a dark room.

    The lamp has been fulfilling its task perfectly for almost a year and is proof that even a damaged lamp can be used to make some nice gadget.

    Cool, I am also a supporter of "do not throw away - use", write to me with information about the parcel locker and you will receive a gift for a nice design :)

    Although I do not like trinkets, I like your workmanship. Minimalistic approach and aesthetics of workmanship. Big Plus.

    Hey - cool, where can you get such a housing? Great price and looks too!

    Super lamp, cool lamp used, and the combination with RGB gives the effect. The basis refers to the era of the 60's.
    If you can, add a video.

    Have you connected a VU meter to something?

    Hello

    As far as I know, such a lamp can be saved.
    It happens that the emission layer breaks off from the cathode and shortens to the heater.
    There are two methods of repair, the first is to roll the lamp, it helps if the cathode fragment is not "welded", the second is to connect a charged capacitor between the cathode and the heater and burn this bridge.

    Visually nice workmanship. In such an application, the lamp is practically immortal. However, it could be used much better by building a semiconductor headphone amplifier inside the housing and trolling friends with the "tube sound". LED backlight spoils the whole "atmospheric" effect of this lamp and instead of retro it is more in the so-called climates. country tuning - it would be better to feed the filament of the lamp.

    Oh there, oh there, tastes are not discussed - the author has the effect he wanted to achieve.
    If I had to cling, I would build a lower stand to match the height of the amplifier, or a completely flat round one
    (with a wheel base and a height of about 1/3 of the lamp height) so that it does not dominate the lamp.

    Does the lamp have an option to modulate the light with sound?

    And it would be great then a small, atmospheric lamp with a current consumption of 6 A per one fiber. As for country tuning, I would like to remind you that this is not a tuned tube monoblock, but an atmospheric monoblock lamp and that's it.

    Certainly it would look better if it was lower than the height of the amplifier, but I bought an aluminum casing from the AliExpress sale on occasion for PLN 29 with shipping and I did what I had.

    The lamp does not modulate the light with sound. It has two programs for step and smooth color change.

    I tried to make a movie of the action, but unfortunately in such poor lighting my old camera and smartphone did not manage, instead of the movie, a "blood sausage" came out.

    I connected a 36 k? resistor to the meter in series with the power supply. A value of 0 on the meter shows the correct supply voltage.

    Maybe someday you will be tempted to add modulation?
    I remember my first "colourophone" - two flashlight bulbs (green and red) placed in a large crystal vase of my parents, powered by a TONETTE tape recorder through two LC filters.

    Very good workmanship, a big plus from me.

    Excellent workmanship, in this application the lamp will never wear out, unless it is accidentally broken.
    As for the comments regarding the use of the filament filament backlight, the lamp would not fulfill its role, the filament filament "shines" too dimly. In addition, such lamps need a large filament current, so you would need an additional power supply.

    AND.
