Product Information

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. Do I get this right: Is the PWM (Pulse Wave Modulator; just to show that I’m aware of the meaning and general function) used to control the laser’s intensity? I have a Neje 30W and it has a temperature output, however they advise you to ‘ignore it’ in the documentation. But I guess the easiest thing is a good enclosure, then the noise will be reduced to a very low level.

It’s really annoying that the fan on the S9 Laser head is continuously blowing (at full speed) regardless whether the Laser is in use or cooling is needed. Combining hydro-dynamic rotation and innovative micro-holes, it increases water flow, whilst decreasing water usage by up to 40%. Four cotton filters (included) remove impurities, whilst three spray modes: massage, rain and combination, deliver a fresh, spa-like experience.

Will take a look under the S10’s hood then and post a picture of the board here when I find the time.

One fact that has me self-doubting myself is that Ortur was able to change the behavior of the fan on the laser module with a firmware update on the controller.

I'm just used to my SWR stuff, which gradually works its way from cold up to red hot and then prompts the horribly noisy industrial grade fan into action for twenty mins. Since the official firmware is not open source (yet – I’m still discussing with them, but you are right, they don’t develop the core firmware in-house), you can’t integrate additional periphery to the board as it is.Cooling has never been so convenient; you'll be able to set timers and personalised schedules and even deliver voice commands via Alexa or Google Assistant. Adjustable Fan Head: Fan head can be tilted left and right, to direct the airflow where it is needed most. I think I saw that in their own firmware temperature would be monitored and if temperature exceeded a certain threshold the laser would stop and pause during a burn until temperature dropped to an acceptable level.

I actually just purchased the S10 as upgrade to the S9, which I intend to sell, but haven’t unboxed it yet. But really care about the air volume provided, otherwise you will again shorten your diode lifetime very much. I suspect for Ortur laser modules they’re designed to have the fan on anytime the laser is being commanded through PWM. At Westinghouse we power lives by providing sustainable energy and reliable appliances, lighting, and electronics for the home.You could potentially test this by providing the laser module 12V and ground but with no PWM signal attached to see if the fan still runs. Some of the technologies we use are necessary for critical functions like security and site integrity, account authentication, security and privacy preferences, internal site usage and maintenance data, and to make the site work correctly for browsing and transactions. Upgrading your shower with a turbo shower head will not only improve the quality of your showering experience, but it can also help you save on water bills and reduce pressure on vital resources.
