Torch holder with GoPro buckle

Below I tell you how I solved the problem of riding a bike in the dark 🙂

I bought this flashlight on Amazon and tried it on my mountain bike handlebar.

The light was immediately very good, but the assembly on the handlebars didn’t satisfy me, turning my head and not seeing anything, especially doing off-road, is not pleasant. I therefore decided to mount the headlight on my helmet.

Starting from a project I found on the Internet, I created a support that allows the torch to be mounted on the helmet, using a GoPro support.

This is the result, printed with a Dremel Idea Builder 3D20 printer.

For convenience I decided to move the electric cable passage. Instead of getting it out to the side I pushed it through the bottom, under the switch. To do this, simply open the torch by unscrewing the front ring nut, remove the electronics, unsolder the connections and remove the cable. At this point I punctured the back of the case with a 5mm bit, had the cable run over again and soldered the connections to the board again. The case has two holes laterally, one threaded for the support screw and one from which the cable passes.

Using the largest hole I inserted a self-locking nut and with a M3 screw passed through the printed support, I fixed everything. I suggest to put a thin soft layer between the torch and the support, I used a double-sided tape. For greater security I used a tireup to lock the torch using the appropriate slot.

The cable is long enough to allow me to keep the battery in my backpack while run. If you decide to keep the battery somewhere else, you will need to extend it or use an extension cord.

The support fits easily into any cylindrical torch, but you are free to download the project and modify it as you like 🙂
I hope this post will help you and help you ride your bike safely, even in the dark!

About autonomous driving

In these days I’m driving an Infiniti Q30, I find it very pretty and even if it has the wrong wheel drive, it can be fun too 🙂

One of the things I like best about this machine is electronic stuff. One of the driving aids I noticed is the autonomous reading of the road signs. I found the thing interesting also because I immediately looked at it from the standpoint of autonomous driving. Right about this context yesterday I noticed something that I did not like. Passing behind a tourist bus I noticed that the car read as a speed limit, as reported by the heavy vehicle that preceded me in a sticker that reported its maximum speed on the highway. In the picture you can see little because I was driving and I took it at a run. However, you can guess what happens: the car signals me as a speed limit of 80 km / h (instead of the 50 real ones) because the coach in front has a sticker that indicates its maximum speed on the highway in 80 km / h.

I noticed this behavior on several occasions between yesterday and today.

Today this is not a big problem, I guide and I know the limits and I know what directions to follow. But if she were driving, wouldn’t it be too easy to deceive her? And in the case of autonomous driving, any fines, who should pay them? Who was in the car? No, he wasn’t driving! The owner? No, he didn’t even drive! The manufacturer of the vehicle? Who hadn’t passed a patch in time?

I leave you with these doubts and with the invitation to use the right pedal until we can do it 🙂

First post :)

After so long it seems that I have found the time to open this blog!

I’m not sure what to do with it, at best I will use it to share thoughts and images.

For those who do not know me, let me introduce myself: my name is Emiliano Carlesi and I live in Rome. I work in computer science (one of my greatest passions, it is not “just” work), I have a 13 year old son and a fantastic partner. I also have two dogs (Olivia and Ambra).

In addition to information technology, my hobbies are mountain biking, archery and (although I haven’t been practicing it for several years) the off road RC.
For those interested, here are some more info about me:
