I paid £9.50 for this Bosch Professional GPL 3 dot laser level, erm, thing. It has flashing/blinking red light error. Which the instruction manual says is either low power level or laser not aligned! Which will it be?!
Let's see if we can fix it!
Hope you enjoy!

I believe you just bypassed the sensor/switch below the hanging laser assembly. Its job is to tell the board when the assembly is hanging freely. If you tilt the device too far, the assembly would hit the side and no longer be able to self level. I believe the issue lies in that sensor or its connection to the board.

The Atmel chip is an AVR or microcontroller, a programmable chip, like a PIC type of chip, just from another supplier, I would assume the chip is pulsing the voltage, so the laser diode flahes. These units (and most others) flash when they're not level. So what you've done here is bypass the level indicator. The chip is programmable, this is done at the factory via the J1 header. So cannot just be replaced with of the shelf components. D1 is probably more likely to be a hall effect sensor, which is actually whats sensing the actual level. Once this gives a coarse level the pendulum finishes the job.

@pdrg Жыл бұрын

The flashing/pulsing of the laser diode is probably all about PWM so as not to overdrive the laser - the bodge may work now and see the laser fading quickly over time?

@jsecret9459 Жыл бұрын

@@pdrg No, you're mistaking a PWM signal to reduce battery life and an intermittent flash. These units flash the laser to indicate it isn't level. If a led/laser/lamp is on at 100hz a PWM signal for instance of 50Hz will reduce battery usage by half and won't be seen as a flickering light by the human eye. While this chip is possibly using a PWM on the laser to increase battery life, it will be unnoticeable to a human eye.

@InnerBushman Жыл бұрын

D1 is infrared proximity sensor or sorts. You can see two "chambers" for the transmiter and receiver. Basically an IR LED and photo transistor in one package. I doubt there's any smarts in that part. The µC is doing all the heavy lifting.

@@InnerBushman that sounds really likely to me. Maybe the IR led burned out (hence no forward voltage that could be found), and so the microcontroller is unable to find out that the pendulum stabilized, hence keeps flashing the laser to mark it as unreliable or out-of-bounds rotated.

The red and black wires are the power directly to the laser itself, they were pulsing since the laser was flashing. By putting power to them, the controller is totally bypassed. Also, D1 was not a diode as others pointed out but a sensor, it may have been the cause and putting a random diode there wouldn't do anything. However, with no part number on it, it would take awhile to find the right part, if possible.

I have a Bosch laser level (not this laser pointer but very similar) mine has a 3 stage on/off switch… 1=off 2=fixed or locked laser 3=self levelling. When it is in ‘self levelling’ it will flash until it has found its level. So it may be fixed but he had it the locked mode (2)

I suggest you research your components rather than just replacing what you think it is. This can do more harm than good. As others said, D1 is most likely some type of measurment component under the pendulum. I would say it is like a Hall Effect sensor and the pendulum has a small magnet under it. Once the pendulum is level, then this switch would turn on the lasers. I also suggest that with your bodge fix , then the unit will never be level as others have said, you just bypassed the levelling components/switch. As an Electronic engineer, I do like most of the ways you go about trouble shooting, but this one, needs a little more time to fix properly.

@BuyitFixit Жыл бұрын

Agree. Opto sensor or hall effect sensor to tell the microcontroller that the unit is within acceptable "level". A rotating level I looked at a couple of months ago had similar but it actually tilts the head into the correct alignment with motors, it was a lot more complicated.

Your repair just bypassed the transistor that flashes the laser, it's impossible for it to flash now so you'll never know if it's out of the self leveling range or has low battery. The voltage on the laser you measured was fluctuating because it was flashing the laser, this isn't a fault, also because the laser was working and flashing it also means those two thin wires were always intact. The programmable MCU was also working because it was able to flash the laser, however the ADC inputs could be damaged. The 'diode' you took out is a combination LED (light emitting diode) and photo-transistor as part of an infrared proximity detector, it detects when the balance is out of it's self leveling range, replacing it with two diodes will just render the self level detection non-functional. I see in the video there's two different flashing speeds for the laser, fast means it's out of the level range, slow means the battery is low, it appears to be failing with slow flashing mode. The previous owner might have put the batteries in the wrong way around the fried the input of the ADC on the MCU or there's a bad soldering joint from manufacturing in the voltage divider resistors for the MCU ADC.

Taking it to a whole new level I see.

brilliant fix......you can now point lasers at stuff thats level or something.....all the best for 2023 dave......and that beardy fella who doesnt know what hes doing🤣🤣👍

I laughed at the “frickin laser” line, been a while since I’ve watched that!

* Yo StezStix Fix..* Probably wrong about this, But I suspect the pendulum's magnet or metal near the coil should change the coils voltage which is fed to a circuit to keep the laser steady.. As you can you imagine if the laser line is not kept rock steady the laser level line would be useless if it not kept rock steady. EG: As someone walks nearby the vibrations from the footsteps are countered by the pendulum's movement from the footsteps within the coils field, ergo the fields voltage changes to counter and keep the Laser rock steady by feeding a voltage that pulls the laser gimbal counter to the actual vibration's momentum. Thumbs up Guys, If that's probably why the wild voltage changes are present..

The 4 pin 'diode' is a reflective sensor, IR LED one side, Phototransistor the other, when there's something IR reflective in close enough proximity it 'switches' on (or off), they're quite easy to get hold of (once you know what you're looking for). Costco batteries, used to buy loads of their AA/AAA but almost every single time I've used them and let them get low I've ended up tearing stuff apart and cleaning up leaked electrolyte. I'm using CPC Pro-Elec cells and batteries now, so far so good plus they're cheaper...

About the “reflective sensor” you mentioned, isn’t that like an opto-isolator or an opto-coupler? Please let me know, I’m trying to learn. Thank you kindly

@@maxwarfield6699 Pretty much, yes, you get reflective ones, slotted ones etc. The one in that Bosch looks a bit like a CNY70 but obvs. no idea of the actual sizes, it could be the exact same type, a tenth the size or ten times larger etc.

I wonder if it wasn’t a diode but some kind of relay or something that let it switch the laser on/off when the (guessing) Hall effect sensor told it the pendulum was out of position? Honestly the flashing is too sensitive and you can probably figure out if it’s too far off level without it anyway.
