A real treasure trove, for example, is the site of the Dutchman Jurgen Krooshoop. In
addition to creative, alternative models, there are also supplementary building
instructions to original Lego kits, in order to equip them with additional functions – for
example, to retrofit a complete Lego remote control with driving functions. Of course,
these models, called Ultimate, need more accessories and more components – Jurgen
Krooshoop also provides the component list on his website.
For example, the Lego-Technic Model 42009 Mobile Heavy Duty Crane can be
upgraded with additional electrical features to fully control the heavy duty crane by
remote control at the end of the day. For the drive is still another XL engine, for steering,
one boom, lifting unit, extension arm, etc., five more M-motors and two other L-motors
are needed. These additionally required eight engines in this example tear a hole in the
household budget – and sometimes the detour via the cheap self-built servos is an
alternative. Whether mobile heavy duty crane, railroad, excavator or Unimog and more –
almost any Lego model can be upgraded with the accessories, it can be with new
electronics and add new features and improve existing ones. In this chapter you will find
the most important thing – have fun and enjoy crafting!
A wonder of technology with all sorts of accessories: The Lego-Technic Model 42009
Mobile Heavy Duty Crane is now completely remote controllable after installing eight
additional Lego motors.
Right tool for the Lego tinkering
Whether you want to bring a simple circuit from the board to the board or assemble a
sensor or robotics kit – for the electronics crafting always one or the other tool is
needed. Depending on the task and construction projects, it is sometimes not done with
tweezers and a soldering iron. Even when assembling simple circuits a manageable set
of tools is needed, in addition to some consumables and standard components, in which
a single purchase is not worthwhile. So over time, not only do you have a toolkit, but
you also have a warehouse for electronic components at home – this section introduces
the key tools and little “helpers” you can use to do some assembling of home
electronics and circuits to be able to use them later in Lego models or even compact in
Flat / Long Nose Pliers – Flat or long nosed pliers are the tool of choice for holding and
gripping electronic components, wires and connections.
Side Cutter – Useful for cutting smaller wires, but can also be used for rough
groundwork during Lego modding and ripping.
Electronic side cutter – Especially when soldering on circuit boards and circuits
indispensable when it comes to soldering and wire projections, etc. to remove.
Stripping tool – If two wires or cables are to be securely connected, the live wire must
first be soldered clean. Use the stripping tool to remove the insulation from the wire
Screwdriver set – All-round tool in the tool box: For most applications, a screwdriver set
with the cross / Phillips / Philips attachment is sufficient.
Tweezers – Just when adjusting small IC legs or when picking out small parts from the
electronics box has a tweezers already made valuable services.
Soldering iron – No lead soldering iron, but a contemporary device with not more than
250 W and if possible with a thin tip. Electronics enthusiasts and those who want to be,
should better use a soldering station with temperature selection for everyday
Vice / third hand – Often indispensable when soldering different small parts and holding
them in place. A third hand in the form of a crocodile clip construction does not cost
much and helps to avoid sweat and annoyance.
In addition to the craftsmanship and the appropriate tool contributes to the success of
the electronics project. The A and O is a sure grip for the object to be soldered – here it
is advisable to put a portable small vise on the desk or simply for 3 to 20 euros to buy a
so-called “third hand” in the relevant electronics market or craft supplies. These two
alternatives are very good for small ones Boards and for soldering plugs to cables. When using the soldering iron in the projects described in this book, the vise is sufficient to allow vibration-free working.
The unneeded areas of the board were secured with masking tape against possible damage
(for example, by dripping solder from the soldering iron, etc.). For larger boards,
however, this can quickly become unstable, here then enough a rubber mat or, if
necessary, a desk pad made of paper, which prevents a soldering iron deposited on it
the table instead or hot soldering spatter can burn into the table. To cut off and shorten
the connecting wires and strands, you need a side cutter or a pair of pliers with a cutting
function. The most suitable for this is a so-called electronics side cutter, with which you
can get better at protruding solder residues and wires on PCBs and cut them clean.
In addition to “standard” standard tools, such as folding rule and screwdrivers in various
sizes – which is just as in the household – is especially for electronic projects optional
tools such as vernier calipers or a sharp knife or cutter, a Dremelset and a hot glue stick / a hot glue gun a great help , A hot glue stick costs only a few euros and just sticks to
almost anything. Especially during assembly and final assembly often helps a drop of
hot glue to give the construction a bit more stability. Should times a board made of
epoxy resin or the like changed, the screw is shortened or a solder joint can be
increased, here helps a cordless screwdriver and / or a Dremelset, which you get in
cheap complete sets with consumables and accessories in stores. If a small screw falls
to the ground, a minimagnet helps, and also a simple fire
For example, it is possible to use it for heating the shrink tube and the like.
