A USB scale without driver

By martinm, in DIY and Programming, april 17,2015.

The Yoctopuce team recently decided to record the weight of each package to be sent, in order to compare the pre-computed weight to the actual weight. And as we don't really like repetitive tasks, we decided to do it automatically. So we bought a few scales with an RS232 output. And this week we take the opportunity to show you in detail how to transform a Kern scale into a Yocto-Scale in a jiffy.

Keybox, email, and RFID

Our blog articles are generally used to give ideas on how to solve issues with Yoctopuce modules.Today, we offer you not an idea but a complete realization, which can be used by any user without computing knowledge...

The Yocto-GPS

By martinm, in New stuff, april 03,2015.

By now, you must have understood it: Yoctopuce R&D department works like a weathercock. The expression is somewhat simplistic, but we do really try to fulfill our customers' expectations. Each time a customer asks us whether we wouldn't want, by any chance, to create a module to do this or that, we carefully write down the request. And we create new products depending on the interest they rouse. This week, it's time for the new GPS module that you have demanded quite often.

Driving a Roomba with a Yoctopuce module

We recently bought a Roomba automatic vacuum cleaner and we started to look at how to hack it as soon as it was out of the box. The Roomba is equipped with a serial port which enables you to control the robot. This serial port uses a Mini-Din socket and works in TTL levels (incompatible with an RS232 port). Luckily, we just announced the Yocto-Serial: a serial interface which can work with TTL levels.

And here is the Yocto-RS485!

In an industrial environment, the 4-20mA standard is a practical and robust mean to move a captor several hundreds of meters away. But when you multiply the number of sensors or the physical parameters to be measured, or when the resolution of analog transmissions is not good enough, you must find another transmission system. That's when the RS-485 standard comes in: it is the industrial cousin of the RS-232. And from today, thanks to the Yocto-RS485, you can interface RS-485 devices with the same ease of use an any Yoctopuce module.
