In short: if you buy a finished DB-01 from me, then no. If you want to assemble all or part of your DB-01 yourself, you should read the following page and deal with it.
As a recommendation: “Buy a DB-01 or build it yourself?”
I designed the DB-01 in such a way that you can build it as easily as possible.
There are a few things you absolutely need. Other things make your work easier, but are not absolutely necessary. There are also things that you don’t necessarily need, but if you buy them and deal with them, they open up a new world for you. For example, a 3D printer good stationary power supply.
The structure of a DB-01 contains a lot of structural parts that can be “easily” printed in a 3D printer.
Print parts yourself or buy them? I will discuss a few facts, as well as pros and cons, in the article “Decision-maker: Buy 3D parts or print yourself?”.
The DB-01 runs on rechargeable lithium polymer batteries. If you also want to work and experiment with your DB-01 on your workbench, a stationary power supply is recommended.
Better said: a “control center for your electricity needs”. Ideally (if you or a friend of yours have the competence to do so) you will have built it yourself from an old PC power supply. You can read an explanation in the article “Stationary power supply for the DB-01”.
In short: a PC power supply offers you all the voltages you need, combined with a lot of amperes and a great price. With a few additional components, you have options for which you would have to spend a lot of money on non-DIY. And a decent power supply belongs on a workbench for electrical engineering.
Yes, a DB-01 has several hundred screws and a few nuts. You should have 3, 4 neatly fitting screwdrivers and a nut box with a small ratchet or a wrench on hand.
If you print the construction yourself, you definitely need a small round and flat file. No 3D printer prints perfectly – here or there you want to remove a burr or enlarge a hole. If you buy parts in my shop, you can decide whether you want them finished or fresh from the printer.
If you want to build the DB-01 completely yourself, you need a soldering station or at least a soldering iron, because you have to connect different cables and components. You may also want to add additional metal threads to your 3D print – you can easily do this with a soldering station.
We hope to be able to offer a suitable connector system soon.
If you need help with soldering, ask a friend, a neighbor or have a look at the webshop (coming soon).
Whether to remove the support structure during 3D printing or to be able to handle small electronic components and cables in the test phase on the breadboard before you finally assemble the DB-01.
A USB hub for data transfer to the Arduinos can be very useful. This saves you the hassle of cabling USB cables back and forth, you don’t mix up ports and you can easily switch the ports on and off at the push of a button. I personally use a 10 port hub. If you really need 10 ports, depends on you. As a developer, I naturally want to have access to the MCUs at any time to make changes or read out data instead of annoying wiring.
You should make sure that the hub is explicitly suitable for data transmission. Buttons for switching the hubs are very useful as they do not wear out the connection points on the PC or on the MCUs.
