Notes on Sub-Ohming

One of the most important elements of every atomizer build is the total resistance of the atomizer. Different atomizer types work best with different resistance ranges for a number of reasons related to: i) the diameter of the resistance wire, ii) the diameter of the windings and iii) factors related to heat transfer. These properties […]

Voltage Drop Tests: Roller, Dingo, Guppy

Here’s a set of tests conducted on a new Roller, a Dingo and a Guppy. The presented method relies on measuring and subtracting the voltage drop component that corresponds to the internal resistance of the battery from the total measured drop. The voltage drop on the battery “outside” the mod is practically the same as […]

Rhodium-plated Connectors – Check

You asked for them – and here they are: Rhodium-plated connectors for the Roller and Dingo! The rhodium-plated brass connectors are specialty items – they have been made for Roller/Dingo owners that demand the absolute best performance from their equipment and never forget to give it the care it deserves! Rhodium-plated brass connectors provide better […]

New Springs, More Options

Let’s get off on the right foot by asking a simple question: What was wrong with the existing spring design? The quick answer is, simply put, “nothing”. Or, better, the answer really depends on your individual criteria. To answer the question thoroughly, we’ll need to see what a hot-spring actually does, and how. Appearances can […]

Notes on Switch Assembly Use and Maintenance

Without regular maintenance or proper handling, the contacts of a mechanical mod may start to overheat, which can cause damage to their silver plating and as a result, misfires. Some usual causes for contact overheating are: i) juice leaked into the switch, ii) dirt or dust, iii) hard, violent, long short-circuits, and iv) successive presses […]

Notes on Voltage Drop

An ideal DC voltage source and a resistor is all that’s needed to start delving into the fundamentals of Electric Circuits, at least on paper. No matter how simple, a circuit with a resistor powered by a DC source is a quite good approximation for many applications, including our beloved vaping devices. Although this simple […]

Design of a 510 Connector

In the last few days, we’ve received quite a lot of questions, along with some really valuable feedback related to the design of the 510 connector on Roller & Dingo. So, it’s now time to put things into perspective! The 510 connector on both Roller & Dingo has been designed to be exchangeable / customizable, […]
