Programmable text displays for Samobor businesses: what to put on a board whose readers are mostly first-time visitors, how long that message may be, how the words get into the unit and what it takes to keep one running from 338 kilometres away. The technical part of this is straightforward. The part that decides whether the board was worth buying is the writing, so this page spends most of its length there.
LED scrolling sign in Samobor — manufacturing, installation, quote
Most towns write their signage for people who will be back on Tuesday. Samobor cannot. A large part of the audience passing a shop window here on a Saturday afternoon has come out from Zagreb for the day, will spend three or four hours in the centre, and may not return for a year. They do not know which entrance is yours, what time you close, whether the terrace is open or where the queue for the counter actually starts. A scrolling text board in this town earns its keep by answering the questions a stranger has, and it fails when it is written by someone who has forgotten what it is like not to know the place.
Who is going to read this board, a regular or somebody who has never been here?
Answer that first, because it changes everything else
Two boards can be identical in specification and opposite in content. A board facing a workforce, a neighbourhood or a set of returning customers can be terse, because its readers already carry the context. A board facing weekend visitors carries no shared context at all, and every message has to stand alone. Before we discuss pitch or size we ask the owner to describe, honestly, who walks past between eleven and four on a Saturday. If the answer is largely day visitors from the city, the content plan looks completely different from the one a business on an industrial plot would need, and it is worth writing that plan before the board is ordered rather than after.
What does a stranger need to be told that a regular already knows?
The four sentences that are actually useful
In our experience the messages that work for a visiting audience fall into a short list. Where the entrance is, when you close today rather than in general, what is available right now, and how long the wait is. That is close to the whole of it. Anything that assumes prior knowledge, such as a reference to the usual offer or last week's arrangement, simply passes over the head of the person reading it. The hardest discipline is removing what flatters the business but tells the reader nothing. A visitor standing outside a confectioner's on Trg kralja Tomislava does not need to be told that the shop is a family tradition; they need to be told that there are still portions left and that the terrace at the back is open. The board is a practical instrument, not a brochure.
How long may that sentence be before people stop reading it?
Character height, line length and the module grid
Legibility follows a simple proportion: roughly one centimetre of character height for every four to five metres of reading distance. Across a pavement, at three or four metres, characters around eight centimetres tall are comfortable and characters half that are not. Since the display is built from modules 32 centimetres wide and 16 centimetres tall, the character height you choose determines how many characters fit on a line, and that number is usually smaller than the owner hoped. Work the other way round instead. Write the longest message you genuinely need, count its characters including spaces and Croatian diacritics, and let that count set the length of the board. A unit that forces every message to be cut in half will be abandoned within a season.
Does a board aimed at visitors need more than one language?
A second version costs time, not just space
Some Samobor businesses see enough Slovenian and other foreign visitors, arriving through Bregana, to justify a second language. The cost is not the hardware. It is that every message now has to be written twice, kept in step, and given its own slot in the rotation, which halves the frequency with which each version appears. Our advice is to be selective rather than complete. Translate the two or three messages a visitor genuinely needs and leave the rest in Croatian. A board where half the content is bilingual and half is not looks careless; a board where the practical items are bilingual and the local notices are not looks considered.
How does the text get in, and who is allowed to change it?
Wi-Fi, a network cable or a stick, and two people who know the password
The controller accepts messages over Wi-Fi, over a wired network connection or from a USB stick, so no data cable has to reach the board position. Content can be typed for immediate display or built as a list with times attached, which is how a board shows opening hours in the morning and a closing notice from four o'clock without anybody being there. The failure we see most often is organisational rather than technical. One person sets the board up, that person goes on holiday, and the display keeps announcing an event that finished a fortnight ago. Two people should hold the access from the first day, and the credentials should be written down somewhere other than in one person's phone.
What does keeping one of these running at 338 kilometres look like?
A spare in the drawer beats a promise from the works
A text board is a simple device by our standards, and most faults are either the supply or the content. Both are resolved locally. Where a module genuinely fails, the spares supplied with the unit let a local electrician swap it in an hour, which is the whole point of shipping spares with every consignment rather than holding them here. The warranty runs for one or two years depending on the build. Beyond that, what protects you at this distance is not a service promise but the design decision that anybody with a screwdriver can change a module. We would rather sell a board that rarely needs us than a support contract that assumes it will.
