Elk bledom products camera8/28/2023 ![]() Not only for their color variation but also for using methods that draw everyone’s attention. In a short time, these types of strip lights got very much popular. Most people know about the elk-bledom is, this is a fantastic LED Strip Light that is easily usable and controllable through the app. There are lots of LED Strip Light that we loved to use in different ways. This is the reason we are going to discuss it in this review. Technological advancement makes us more curious to know how we need to use it more carefully. Many users of Elk-Bledom don’t know about it. Even other Bluetooth devices can be used to control this camera feature. This fantastic but hidden feature raises lots of questions. The most astonishing hidden feature of this LED strip light is, it can work as a hidden camera. Yes, we are going to bring more secrets about this LED strip light only for its different hidden features and service. I may implement control ones after investigating their functionality some more.Do you know about Elk Bledom? The LED strip light? If you don’t, then this is the right time to know about it. There are 15 commands in total that I've managed to find via the app, of which 6 are marked visual: as these control the actual output of the three channels, these are the commands I've focused on implementing. "wl.cond" -> int - 3x 8bit values (hour, minute, second) "wl." -> 0-100 | Both values should have the Some of these require further investigation, and some seem to be related to interesting functionality like timed control. There are 17 different parameters that are used by the associated Android application their types are listed below. It's worth noting that there's quite a lot of logic in the app that seems redundant - such as advertising. However the generation of those lists appear to be identical, so the intention isn't clear. The Android app differentiates between control messages and data messages - using different device lists as targets. Although using 0x00 seemsīyte 6 -> Parameter | to be acceptable to?īyte 8 -> Optional? | Tends to be set to either 16 or 0 doesn't seem to effect functionality. ![]() The device advertises itself with the following description:īyte 2 -> Optional? | Seems to work when set to 0x00, but app sets to a unique value per command.īyte 4 -> Parameter | Where a parameter is not in use, it appears to be set toīyte 5 -> Parameter | the value of 255(0xFF) - 11111111. (With a current of up to 3.5A)Ī generalised interface could allow the bluetooth control of other peripherals that require PWM - i.e. Whilst the LDO can regulate voltages up to 24V, the MOSFETs are only rated to drain up to 20V. The circuit has an operating voltage of 3.3-20V. Here's a simple block diagram showing the components in use: ![]() The circuit looks like a standard RGB LED control circuit whereby the MCU controls the target LEDs by means of Pulse Width Modulation (PWM) via the connected MOSFETs. No LEDs or other form of status indicators are present when the device is operational. The PCB is marked with "SN30301533", but I can't find find any reference to this online. There's also pads marked "V", "G", and "IR". The underside of the PCB contains pads for soldering on connections for both input power and channel output. The switching components are N-Channel MOSFETs (A2SHB), and a 7533M is used for voltage regulation (3.3V from a maximum of 24V) for the MCU. There's very little to be gleaned from opening the device it's a simple looking PCB with an unmarked 16 pin SMD (SOT552 form factor?) MCU, accompanied by a 24Mhz oscillator.
