electronicNerd Betterwith too much oil than no oil :-)

walter66 04/11/2022
The order arrived quickly, two days earlier than the stated deadline. The packaging is good. Pleasantly surprised by the quality of the plastic of the housing, it has chain lubrication that is not very well solved, at the minimum oil supply, too much comes out on the chain and the lower part of the housing. The power of the motor is supposedly 5000W, this is not possible, in reality it is maybe 500 - 700W. For this product price, a good purchase.

As I expected, not the finest tool, but good for small jobs. Don't know how long the small motor will last, hope the best :-) Many of these tools use the same batteries, fine I allready have a screwdriver using the same :-))

Not unconditional positive comment, the box missing locks and because of that the "horns" have been pressed out of shape! The hot air gun works OK, haven't tested it complete yet but blows and heat the air what is what you can demand of the gun :-)

electronicNerd The maximum range is not 40 meters but only 30 meters (tested to 29.97meters, every distance above blanked out the display), tested last night where I could see the red spot from the laser. You should change your adv. to: distance from 3cm to 30m. For me it\'s OK, I only need up to 25 meters, as a distance-meter for shooting-range.

First of all, I thought the green light was invicible, then I tried, several times, the lock to open the power, without luck, then I reversed the lithium-cell, tried the lock again several times, holding the powerbuttom activated and FINALLY!!! turning the lock I saw some green flashes and found a point where the lock gave connection to the battery, pulled out the key, never more to be turned!!!! It was about 1 minute from being returned as defect!!!!!!!!!! An ordinary use of + and - on the lamp would have been nice and omitting the switch(lock) even more nice!!!!!!! When working as ment, the green light is perfect, can be seen in 50m distance even in sunlight.

D-SUN have a lower un-loaded heating, and I can see the ID of the chip. Some of the similar PSU units with less components and same physical measurement, but with the chips ID erased is heating up 20-30 degree even un-loaded, thats why I always seek D-SUN.

This DIY FM radio using the TDA5807 and LCD display has a much cleaner sound than the designs using the TEA5767. It does have digital controls for the volume where the lowest level, 0, is still audible. Like other FM kits, it only stops when it scans and detects a strong signal, so weaker stations may be missed. Increasing the volume allows the lights across the top to light up, and if sufficiently loud, the centre ones will start to change colour (curious when the installed LEDs are just two pins). Some written directions might have been helpful. To help secure the antenna, which was threaded, I used a M2x8mm bolt. The three lengths of bolts was a little confusing about where they should be used. In some places, I actually replaced the metal bolts with M3 x 12 mm nylon bolts. A headphone jack might be a nice addition.

Q: KWS-MX18.I wonder why the voltage-display lower it's reading when the current increase.Unloaded it shows approx. the same as the other testers, but when loaded even with a light load, the voltage-display differs from what the other tester (in series) is showing, as much as 0.2-0.3V lower, the current readout is following the other testers. The KWS-MX18 is the first tester in serie when testing, followed by the Keweisi KWS-V20 or the Keweisi AT34.
