Instructions pour la télécommande double
Pourquoi se limiter à un seul tube quand on peut en utiliser deux ?!
J'expérimente avec deux tubes de light-painting depuis quelques années, mais gérer un tube dans chaque main, plus le déclencheur, me semblait limitant car je ne pouvais pas les allumer et les éteindre facilement. En bref, je n'appréciais pas le processus.
Un jour, j'ai demandé à Christian, le roi du DIY de l'équipe, de prototyper une télécommande double qui pourrait contrôler les deux tubes avec un seul bouton. Cela a fonctionné à merveille. Nous avons créé de nombreuses images avec des tubes doubles depuis, et ce n'est que le début.
Pourquoi utiliser deux tubes ?
- Mix colors: Combine two different tube colors in a single exposure.
- Combine modes: Use strobe and constant at the same time with a single button press.
- Create larger light traces: Paint wide shapes in one pass.
- Reduce blur: Shorter painting time for shapes such as circles means less risk of subject movement.
Ma prise pour le light painting à double tube
Voici une photo de la façon dont je tiens tout lorsque je travaille avec deux tubes. C'est un peu encombrant pour tenir dans une seule main si vos mains sont plus petites (Salut Kim !), mais vous pouvez sécuriser votre installation en ajoutant des élastiques ou des sangles auto-agrippantes pour fixer les deux tubes ensemble.

Devez-vous modifier votre matériel pour faire du light painting avec des tubes doubles ? La réponse courte est non. Vous pouvez absolument utiliser deux tubes indépendants, les laisser allumés et peindre pendant toute la durée de la pose, ce que nous appelons l'outpaint. Mais pouvoir contrôler les deux tubes avec un seul bouton simplifie le processus.
We've had many requests from DIYers in the community, so here are the detailed instructions. Fair warning: this build requires a bit more skill and equipment than our usual projects. If you give it a shot, we'd love to hear how it goes.

Instructions de câblage de la télécommande double
Matériel nécessaire
- Two flashlights, each with its pressure switch. We've had good results with the Nitecore P10v2 and Klarus XT2CR PRO.
- Soldering iron
- Solder
- Flux paste
- Heat-shrink tubing in two sizes: one for individual wires and one large enough to cover all connections
- Wire cutters and wire strippers
- Heat gun
- Electrical tape, optional for extra insulation
Préparer les cordons
- Cut each pressure-switch cord about 50 mm (2 inches) from the remote connector end. You can discard one of the two pressure-switch ends.
- On one of the cut pressure-switch ends, carefully remove 25 mm (1 inch) of the outer insulation to expose the internal wires. Be careful not to nick the insulation on the individual wires inside.
- If the wires are wrapped in foil or braided shielding, cut it away and discard it so only the colored wires remain exposed.
- Strip each wire to expose 10 mm (about 3/8 inch) of bare conductor. Work gently to avoid cutting any strands.
- Repeat steps 2 to 4 on the flashlight-connector ends of both cords.
Pré-étamer les conducteurs
- Heat your soldering iron to 650°F (343°C).
- Apply flux paste to each exposed conductor, then pre-tin them with a thin coat of solder.
Soudez d'abord les extrémités du connecteur de la lampe torche
- Solder the two black conductors from both flashlight-connector ends together.
- Solder the white conductor from one flashlight end to the red conductor from the other, and the red conductor to the white conductor from the other. This cross-wiring enables reverse-mode activation: one flashlight will be in continuous mode while the other is in strobe mode, and pressing the remote toggles them both. If you prefer both flashlights to stay in the same mode, connect matching colors instead: red to red and white to white.
- Bend each of the three conductors on the remote or pressure-switch end into a small hook. Do the same for the three joined conductors on the flashlight end. Interlocking these hooks before soldering creates a stronger mechanical connection.
Glisser la gaine thermorétractable
- Cut a piece of the larger heat-shrink tubing and slide it down the cord on the flashlight-connector end, out of the way of where you'll be working. This will cover all the connections at the very end.
- For each individual wire pair you're about to join, cut a piece of smaller heat-shrink tubing and slide it down that wire.
Soudez les connexions de la télécommande
- Solder the black wire from the remote to the joined black wire on the flashlight-connector end.
- Once the joint has cooled, slide the small heat-shrink piece over the connection.
- Repeat steps 13 and 14 for the remaining wire pairs.
Appliquer la gaine thermorétractable
- Use the heat gun to shrink the small heat-shrink pieces firmly in place. If any connections remain partially exposed after shrinking, wrap them with electrical tape to prevent short circuits.
- Once all individual connections are insulated and cooled, slide the large heat-shrink tubing down to cover everything. Use the heat gun to shrink it into place, sealing the whole assembly.
Voilà ! Votre télécommande double est maintenant prête.
Le résultat final
Dépannage
- La lampe torche ne répond pas après le câblage ? Vérifiez chaque joint de soudure individuellement pour une connexion froide ou incomplète.
- Comportement inattendu ou aucune réponse ? Assurez-vous qu'aucun conducteur nu ne se touche, car même un court-circuit bref peut causer des problèmes.
FAQ
Pour commencer
- Do you need a dual-remote switch to do double tube light painting? No. You can use two independent tubes and simply leave them on during the whole exposure (what we call outpaint). But a dual-remote switch lets you control both tubes with a single button, which makes the process much more efficient and enjoyable.
- Can I control each tube independently with the dual-remote switch? No. The switch fires both tubes simultaneously. If you need independent control, you'll need to use two separate remotes.
Possibilités créatives
- Can I use two tubes of different colors? Yes! That's one of the main advantages of using two tubes. Combining two colors in a single exposure opens up creative possibilities that are impossible with a single tube.
- What happens if I wire the conductors without cross-wiring? Both tubes will operate in the same mode at the same time, either both in continuous or both in strobe.
- Can I use this with other tools, not just light-painting tubes? Yes! Any two devices that are compatible with your flashlights could work. We also used it with Blades and Whips so far.
Matériel et compatibilité
- What flashlight models do you recommend? We've had good results with the Nitecore P10v2 and the Klarus XT2CR PRO. We haven’t tried yet with the Olight Warrior 3s, which has a magnetic pressure switch, so we can’t recommend it at the moment.
- Do you need to use two flashlights of the same model for it to work? No. You can mix different flashlight models as long as their pressure switches share the same wire color configuration. What matters is that the internal wiring matches, so the cross-wiring works as intended.
- Will this work with any pressure switch, or only specific models? It depends on the wiring inside the pressure switch. We can only confirm it works with the models listed above. If you try a different model, check that the wire colors and configuration match before soldering.
- Is the dual-remote switch weatherproof? No. The heat shrink provides basic insulation, but this build is not designed for wet conditions. We'd recommend keeping it dry during shoots.
Construction de l'interrupteur
- Do I need soldering experience to build this? Some experience helps. This build is more demanding than our usual DIY projects, so if you've never soldered before, we'd recommend practicing on some scrap wire first.
- How long does this build take? Plan for one to two hours if you're comfortable with soldering. More if it's your first time.
- Where can I buy the materials? We've linked the flashlight models above. For the rest (soldering iron, solder, flux paste, heat shrink kit, wire cutters and strippers, heat gun), any well-stocked electronics or hardware store should carry everything you need.
- Can I adapt this to connect more than two tubes? In theory, yes, but the wiring becomes significantly more complex, and we haven't tested it ourselves. But we might very soon! We'd love to hear from anyone who tries it.
