Late for your Christmas gifts?Last-minute high-tech ideas

What to buy at the last minute with a reasonable budget? We can advise you to look for smartphone accessories. Everyone has one, so you can't go wrong.

There are a lot of pretty clever things, for example small lenses that will boost the photo capabilities of the phone. Even if the quality of the camera has greatly improved in recent years, not all of us have great smartphones. But there are affordable ways to boost the capabilities of your smartphone.

Like these little lenses that fit in your pocket and that you can attach to the phone camera very easily thanks to a rather artisanal clip system. You have the wide angle lens, the macro lens to take precise photos of a plant, an animal, a small object. And then you have the fisheye lens, which distorts like looking through the peephole of a door.

It's called Pixter, count a little less than 30 euros per lens. There are also packs with three lenses for around fifty euros.

For teleworkers: a practical tool

Another very practical accessory. For teleworkers who often only have a small office in the corner of an apartment, there is a small accessory called Phoneside, which has just been awarded the Lépine competition.

A small smartphone holder that will attach to a laptop computer, and which will transform your phone into a second screen. It's adjustable according to the smartphone, with or without a case... Super practical for multitasking and especially video sessions: launch a video session on your smartphone screen and be able to continue taking notes on your computer screen (instead of to put his phone on the computer by hiding half of the screen!). Especially since the cameras of smartphones are often much better than those integrated into laptops.

Headphones... but you don't put them in your ears

Ideal for athletes in particular. These are called bone conduction headphones. It looks like a pair of classic headphones, except that instead of pushing them into the ears, they are placed right next to them, between the temple and the cheekbone. And you can hear the music perfectly - even if you cover your ears or put earplugs for example.

The sound echoes through the bones of my face. More specifically, the headphones will transform the sound into mini vibrations that pass through the bones of the cheekbones and cheeks to reach the inner ear directly, without passing through the eardrum. The result is quite impressive - without reaching the sound quality of high-end headphones, let's be honest.

First advantage, and not least: you no longer risk damaging your eardrum by listening to music at full blast - in general, ENT specialists advise against headphones - since the eardrum is not stressed.

Then, we can listen to music and continue to hear what is happening around us. In the street you no longer take the risk of being run over by a car that you did not hear. For cyclists, runners it is ideal. And then in the office too, you can listen to your music in the open space while hearing what the colleagues around are saying. The ones I wear were developed by a startup called Aftershokz, it costs between 70 and 150 euros depending on the model.

For children, a contactless wallet

It's called the Money Walkie, and I find the principle very clever. It takes the form of a small rectangular object in the shape of an animal (parrot in this case, but also whale, panda, rocket), no bigger than a matchbox.

And it will serve as a contactless bank card to buy sweets, games, like a traditional bank card. It is linked to the parents' bank account (weekly transfer, one-off... or which can be deactivated in the event of pocket money deprivation).

But obviously, you load it with the amount you want, so we can put pocket money on it, and we can also track expenses via a dedicated application. It allows you to learn how to use dematerialized money and it is more reassuring than walking around with cash. It costs around thirty euros.
