If you come to Rome, Italy, probably you are looking for historic monuments - Romans, Medieval, Renaissance, Baroque - food, or probably the atmosphere.
More than historic monuments in RomeWhen in Rome don't miss the opportunity also to find something interesting for your next project in this short list (please be free to comment if you find out more, or if you want to add something more). The list is short because Rome is not a big city, and for sure not a big market for these kinds of goods.
Head to northern part of Rome, some kilometers outside the historical centre, you can find adelicious deposit of mechanical components (Bruno Bentivoglio - http://www.brunobentivoglio.it/).
In his deposit you can find every kind of good, starting from most complete mechanical aircraft, helicopters, turbine motors, hydraulic components, and more and more.
Simply ask them to tour the deposit and find yourself also lot of woodworking and metal tools, ranging from simple wire solder, to big knee mill and lathe, passing by spot welder and so on.
I believe they buy big lot from military and failure auctions, so the deposit is countinuosly changing.
The site is not complete in relation to the inventory, but you can make them a call.
Look how big is the deposit:
And what you can spot from the highway:
I'm not affiliated, nor authorized to publish photos from inside, but I'll ask them, because is interesting if you are far away.
Definitely a place that worth a visit. Open in work days
Rome is not famous as Shenzen for his electronic market, despite there is a small silicon valley and lot of space production center in the Tiburtina district. So is really difficult to find good source of electronic components.
Magistri & Co (http://www.electronicsurplus.it/) is the place you have to visit to find precious components, cables, dissipators, valves and more.
This time is located on the south of Rome, not far from the city, and the website is more or less comprehensive of the warehouse.
Maybe you can find some military esotic connector, shielded silicon cable, vacuum tubes and lot more. Also here I'm not affiliated, nor authorized to publish photos from inside, but I'll ask them, because is interesting as for the previous one.
Another place that worth a visit. Open in work days
A little of both: Porta Portese
Probably you already now the historical flea market in Rome, every sunday on the neighborhood of Trastevere. Here you can find, depending from your luck, something really valuable at affordable price, but most of time, actually you'll find overpriced used tools or equipments.
Please for directions and photos check https://it.wikipedia.org/wiki/Porta_Portese (italian version is most comprehensive).
