Audi 100 park - dash - number plate light problem

EN
In this post, will expain about Audi 100, C4 model 1994. It lost park lights, number plate, dash backlight, and.. fog light.
All that was caused actually by single piece of plastic that cost perhaps no more than 0.20e. As you can guess is not for sale separate.

LIDL Airgun problem[fix]

ENBG
I bought that Airgun from LIDL maybe year and half ago and recently it.. die. The reason was.. that stupid thermo-fuse (yellow one). Removing it, and clamp the heating wire straight to the same spot where it was and voila - we`re back in business. Преди година и половина закупих от LIDL този пистолет за топъл въздух който реши в един прекрасен момент да издъхне. Оказа се термо бушона. Разкарах го, и стегнах реотана направо на негово място. Все още работи без проблем.

DELL 14” LCD backlight fix

EN
That screen was “dead” by meaning there was no back light. Actually, if you plug some signal to it and start, the monitor has backlight for few seconds and then - nada. Interesting, it has 2 lamps and dual controller but both lamp was tight to the one of the channels. Anyway, what my DIY fix was: remove one SMD transistor, and solder new one.
Extendet story - IC backlight controller, send signal to one MOSFET via smd transistor(removed by me). That MOSFET control the power going to the lamp transformers. I solder new transistor to the IC power supply lines. So, when get power to monitor and push ON, that transistor “open” the mosfet and here backlight is on. In that way I lost the dimm function and backlight is always to MAX but for me that is fine, because that screen should be only use for test, or as screen for one CNC project.

RGB LED control via Arduino and BT serial

ENBG
In that topic will show my first attempt to create R-G-B LED control via timer`s PWM and serial commands based on HC-06 interface hardware and BT serial app for Android. Това е първият ми опит да използвам сериен порт базиран на блутут комуникация между Андроид телефон и ардуино нано. RGB диода се управлява посредством шим базиран на хардуерен таймер

KENWOOD car player - control from steering wheel

EN
Hi there,
That DIY is dedicated to Kenwood KDC-6051U or how to use your steering wheel audio control buttons to take control over it.
Based on specs, the unit should accept commands on cable. That sound great, but there is bad news also - there isn`t any info about the protocol used(or at least I can`t find one). On the market there are products(of course from KENWOOD is the first option) that read your steering controls and put necessary codes to the unit. That cost about 60e for the box and 25e for cable in KENOOWD one, and little less for the other brands. That is quite a lot if the whole unit cost 170e.
From what I check on that “communication” cable constantly come +5V. There is no action if I tight it to pot and try different resistance. Well, obviously is not PIONEER/SONY way. My shot in the dark is that they use single wire protocol by pulling to GND that line in certain amount of time to generate start - 0 / 1 - end sequences, but to be sure I have to buy one ready and to check what is doing so it isn`t how will be for now.

Xantia Mk II odometer

Hi there,
I have no idea if you`ve got to the point when your dash start loose the sane but here is some tip:
When you take the unit out and rip it apart in small corner of it you`ll find IC C46CM6. That is 1KB of memory, seems to be enough to keep the “books” of that odometer ecu. So, now getting your new dash you can de-solder the chip out from the original one, and solder it on the “new”.

And ta-daaa - here is your kilometers back. But there is something else.
In that memory are stored some parameters for the fuel tank,fuel tank arrow and some that clue has only the developer of the unit. In that case I will offer you other road. Again remove it from the board and put it on programmer:

Xantia XU7JP4 - 1.8 timing belt

EN There are many manuals how to replace that timing belt, but here wish to show my first time on Xantia
Engine is LFY XU7JP4 model 1999-2000 with tension pulley, which is semi automatic with indicator arrow.

! In my case the accessory belt pulley`s bolt(what is mounted on the crank) was really hard to release. I`ve need torque gun for it. Suggest to you to use sam, not try with wrench.

Peugeot 406 / Xantia window buttons / бутони ел прозорец

ENBG
Do you have trouble sometimes with your Peugeot 406 electrical windows? Slow going up, or do not go at all? The reason is in the button contacts. Of course you can take the motor out, to clean and grease it. And also to take some care for the window rail to be smooth the movement. With small crew driver pull out the button. Then, carefully take out that gray cover and do not loose the pin. With small pliers take out the spring contact and with file or emery paper clean them. Then fit all in reverse order. Keep in mind that the passenger window power pass via driver`s side button. Take little time and clean all. Is much better. Имали ли сте проблеми с ел. прозорците на Вашето Пежо 406? Бавно и мудно вдигане, или понякога дори да отказват. Причината се намира в патина/нагар по контактите на бутончетата. С малка/ки отверки се изваждат бутончетата и внимателно се отваря сивото капаченце.Просто внимавайте да не загубите малкото пластмасово "чепче" което реално натиска. С малки, подходящи клещички изваждате подвижната пластинка и с шткурка/пиличка зачиствате. След това се сглабя по обратен ред. Ако желаете все пак, можете и да подобрите работата на мотора и механизмът чрез почистване и смазване. Също така, имайте предвид че захранването за пасажерската предна врата минава през бутона на шофьорската врата.
