Dreadbox ANTIPHON Manual de usuario
Before you start the construction of this DIY project, make sure that
you have basic soldering skills and that you can identify electronic
components. If it is your rst time in soldering, there are several tuto-
rials on youtube, that will help you :)
It would be easier and helpful for you to work on a big desk, so as
to have plenty of space to work on. Also a room with an open win-
dow would be perfect when you solder.
Before you start the soldering process, make sure you have all the
components needed and noted in the BILL OF MATERIALS SECTION.
Please note that we might have included more components than
needed or (hopefully not) less. It would be very helpful if you count
all components before starting the project, but without removing
these from their bags .

TOOLS YOU WILL NEED
4
Locate and solder all 45pcs of 33K resistors.
When you are done, cut carefully all the excess leads.
STEP 1 - RESISTORS
5
Locate and solder all 41pcs of 100K resistors.
When you are done, cut carefully all the excess leads.
Locate and solder all 22pcs of 470R resistors.
When you are done, cut carefully all the excess leads.
Locate and solder all 20pcs of 18k resistors.
When you are done, cut carefully all the excess leads.
There are 3 different kinds of Diodes in the Kit. Here we are looking
at two of them, 1n4148 and zener 3v6. As they both look almost
identical, in order to distinguish them, Zener 3v6 diodes not only
have a “3v6” mark on them, but you can also know them from their
quantity. Zener 3v6 are the fewer than the 1n4148
1n4148
zener 3v6
zener 3v6
Locate and solder all 11pcs of 3k3 resistors.
When you are done, cut carefully all the excess leads.

Now, we will install 2 components: 2 pcs10R and 17pcs zener 3v6.
When you are done, cut carefully all the excess leads.
WATCH OUT FOR DIODES ORIENTATION!!!
THE BLACK LINE ON DIODES , SHOULD MATCH THE DEPICTION ON THE PCB
Locate and solder all 19pcs of 1N4148 diodes.
When you are done, cut carefully all the excess leads.

STEP 2 - ICS & SOCKETS
Locate and solder 11pcs of TL074. Some ICs have a dot, while oth-
ers have a semicircle cut. On the pcbs the orientation is indicated
as a semi- circle. When your IC does not have a semicircle cut, but
instead it has a dot, the dot should match the semicircle.
BE EXTRA CAREFULL, max soldering temperature should be 300oC de-
grees for 10 sec/pad, and if you do spend all 10 sec on a pad, make
sure to leave the IC to cooldown before proceeding to the next.
I usually solder these at 260oC for 1-2 sec, with no problems.
Locate 5pcs of 16pin IC socket and 1pcs of 8pin IC socket.
8
STEP 3 - CAPACITORS
Locate (in their dedicated bag) and solder all 61pcs of 470 pF capacitors.
When you are done, cut carefully all the excess leads.
9
10
Locate and solder:
- 29pcs 100nF (marked 104) ceramic capacitors.
All of the unlabeled capacitors on the PCB are 100nF
- 17pcs 10uF electro capacitors (blue ones, polarized)
- 1pcs of 220uF electro capacitor (black one, polarized)
Polarized capacitors: The longer lead goes to +
Wrong soldering
BE CAREFULL to solder the electrolytic capac-
itors as tight as possible, otherwise they might
not t between the pcbs!
