== Information ==
''' Advantest TR4172 Specifications '''

The TR4172 Spectrum analyzer is a microprocessor-controlled,
intelligent instrument with a frequency range from 50 Hz to
1800 MHz. in addition to the spectrum analyzing function,
the integrated tracking Generator of TR4172 enables analysis
of frequency response of Filter Amplifier and so on TR4172 is the first Spectrum analyzer with a capability for
measuring phase response and group delay of Filter or Amplifier at resolutions of down to 0.1 deg and 0.1 ns
respectively, up to a frequency of 1800 MHZ.

The integrated tracking Generator along with the analyzer’ร
intelligent control capability, permits correction of the
analyzer's frequency response itself allowing precision
level measurement.

A wide dynamic range is ensured by the low higher-harmonic
distortion level of 90 dB at and above 20 MHz, with respect
to a signal level of -40 dBm.

The display screen has a dynamic range of more than 95 dB
and permits direct observation of Filter responses with
large attenuations.

The vertical resolution of the scale can be selected from
10, 5, 2, 1, and 0.1 dB per division, observation of a
ripple level of even 0.01 dB is possible with the maximum
resolution setting.

Use of the SAVE switch makes various measurements available,
with which up to eight sets of measurement condition data
are stored in the internal registers and recalled as needed.
Since the internal memory is backed up by a battery, its
contents remain intact even if the device is unplugged from
its supply outlet.

All front panel functions are remotely controllable with the
GPIB Interface (standard supply) for automatic measurement.
The CRT display presents all pertinent measurement data. The
signal response trace and measurement data on the screen can
be output to an X-Y plotter simply by connecting the
instrument*ร GPIB connector to the plotter'ร input with a
GPIB cable and operating the relevant front-panel switches,
without the need for running an output program on the GPIB
controller TR4172 also provides various convenient features to enhance
measurement flexibility and efficiency, such as multiple
marker, zoom, automatic centering, automatic enlargement,
auto-peak search, logarithmic scaling, and four page
memorized display.

== Status ==
The device is overhauled by [[User:Crashjuh|Crashjuh]], with some help from [[User:Maxell|Maxell]] and [[User:Peterbjornx|PBX]]<br>
At present, there are again a number of buttons that refuse service.<br>
These buttons would therefore be replaced by new momentary-contact push buttons.

Using a stencil, solder paste and a hot-plate to reflow-solder SMD components

== About this workshop ==

=== Intro ===

Surface Mounted Devices (SMDs) are small compared to Through Hole (TH) electronic components, and some electronics hobbyists find them difficult to work with: difficult to see and handle, when you sneeze, you loose them and you can not easily use them on 2.54mm raster prototyping boards.
On the other hand, SMD devices allow much more lightweight and compact projects,are most often much cheaper than TH variants, and sometimes there simply ''are'' no TH variants available of a component, requiring the use of break-out or adapter boards - both kludgy and expensive.
Also, Printed Circuit Board (PCB) prototype manufacturing prices have become much lower, CAD tools to design them have become more accessible to hobbyists, and a proper PCB is much easier, reliable and often faster to assemble than the identical circuit on a 2.54mm raster prototyping boards - especially when you make a (small) series of the same board. So, if your hobby-elecronics work-queue is long enough to wait 2 weeks for PCBs to arrive, NOT using 2.54mm raster prototyping boards and TH components makes sense and may save time and money.
The question then becomes: how can you deal - in a hobby context - with SMD components that are difficult to see handle, and that you loose when you sneeze.

=== Beginners ===

If you are an absolute beginner, you will make a badge during this workshop. The badge will take about one hour (more if a lot of people participate). It can be done much quicker. The record time is 12 minutes.

The badge workshop uses a workflow that alleviates some of the difficulties using tricks, (simple) tools, physics and appropriate materials.

Instead of solder wire, you will use solder paste to solder. You will apply the solder paste to specific areas of the PCB using a stencil. While we are doing this some physical properties of the solder paste, the metal and flux it contains and the properties of the materials in the PCB will be discussed and explained how this helps the soldering process.

Next we will use a mirror and tweezers to place the SMD components on the PCB in their correct position and orientation, with an explanation of tricks, tools, rituals and environmental factors that make this more enjoyable. In addition, while we are doing this, the function of the electronics components will be briefly explained and what to watch out for.

After we have finished placing the SMD components, the assembled PCB will be "baked" on a stove. Again, there are a few do's and dont's, but in general this part is quick, and somewhat "magical" if this is the first time you see reflow soldering in action.

If necessary, small problems will be fixed, a battery holder attached using a normal soldering iron, and the badge will be tested. Success rate is almost 100%

Finally you will return the tools, discard your garbage, clean-up your workspace and wash your hands.

=== Experienced ===

If you have some experience with the workflow and can work independently, you may opt to make a game. This will take about two hours. It can be done much quicker. The record times is 41 minutes.

If you want to make the game, it is assumed that you have worked with solder paste and a stencil before. You may pick up a few tricks, but there is less time for explanation.

After finishing you will return the tools, discard your garbage, clean-up your workspace and wash your hands.

=== Warnings ===

During this workshop you may come into contact with potentially harmful materials and tools like lead, flux and soldering equipment. Please,
* Do NOT eat or drink during the workshop UNLESS you wash your hands with soap first.
* Do NOT pick your nose, ears or rub your eyes during the workshop UNLESS you wash your hands with soap first.
* Do NOT go to the toilet during the workshop UNLESS you wash your hands with soap first.
* DO wash your hands with soap AFTER the workshop
* When using pliers to cut component leads, HOLD the wire-end you are cutting to prevent it from being launched at someone or something
* Be careful with the stove. If you touch the hot stove your hand, it may stick to it. This can be painful and may require an emergency room visit
* In general: treat tools (litteral and figurative) with respect - "accidents" can be painful

== About the Projects ==

During the workshop you will make either a badge or a 'blocktris' game. The badge contains a ''larger variety'' of different components. The game contains a ''larger number'' of components. Neither is very difficult to make, but I consider the badge better for beginners: you learn more, and it costs less.

The workshop can also be fun for more experienced people: how quickly can you make a badge or a game, and how well does it look? (hint: rework must be avoided). The current record times for succesful hotplate reflow soldering are 12 minutes for a badge and 41 minutes for the game. The record time for succesful hand soldering the badge is 21 minutes. So far no one has even attempted to hand-solder the game.

=== The Badge ===
Contains 24 blinking RGB LEDs, various support components, a microcontroller and you can actually write your name on it.

[[File:hackwinkelbadge.jpeg|thumb|alt=Badge image|image of the hackwinkel badge]]

Both [https://github.com/hackwinkel/tag-hardware | hardware] and [https://github.com/hackwinkel/tag-software | software] of the badge are MIT licensed open source.

=== The 'blocktris' game ===

The game contains 200 RGB LEDs in an array of 20 x 10 pixels controlled by an ESP32-C3 microcontroller module, ideal for playing 'blocktris'.

== Costs of this workshop ==

The Costs depend on what you do:
* Badge: 0 euro + a voluntary donation to the space each
* Game: 8 euro + a voluntary donation to the space each

== Participating ==

=== general notes ===

If you want to join the workshop, please write your name in the table below noting what you would like to make (badge and/or game). '''Add more lines if necessary. Depending of the number of people, we can do multiple sessions'''

Doors open 11:35, first session start: 12:00, last session start: 16:00

'''Note:''' The "ideal" number of participants per session depends: Beginners/kids (with adult supervision): 5-10, People with some prior experience working with stencils, solder paste and a hot-plate: ~15, Experts: 20 (tools bottleneck). The maximum for a session so far was 42, and that was only possible because there were lots of experts helping others out, but the tooling (stencil and hotplate) bottleneck resulted in an overrun of ~ 2 hours.
'''If this is your first time working with stencils, solder paste and a hot-plate OR if you are younger than 14 OR if you have never done any soldering before, put this in the remark'''s - it is definitely not a problem, but affects how the workshop flows.
