A couple of days back, I was talking about self-driving trucks and how they will help in making companies more productive. I came across this one where a robots sorting system helps a Chinese company finish at least 200,000 packages a day in the warehouse. Quite an interesting video to watch. I must admit, I was pretty impressed!
Just the other day, I was passing by a mall and there was an event in the main foyer. I thought I would go over to take a look at what systems they were using. When I passed the speakers, I had a look at them and saw that they were of this brand…Depusheng. They did not sound bad as it was not being pushed. So I waited a while to see how they sounded like
I did not have to wait long. After a while, the emcee started speaking and conducting games. That is when I started to find the speakers getting distorted. Then they started playing music through it and I heard the unmistakable “crack” sound that happens when a speaker is over-driven or the sound a speaker makes when it cannot handle the power of the amplifier.
When I got home later that day and scoured the China online sites like Taobao and Aliexpress, I found the exact line of speakers that I saw on sale there. They were very inexpensive and upon further checking, I found out that there is a speaker rental company renting these very same speakers and system for a bargain basement price. People like these kill the market by renting out cheap, inferior speakers for a cheap price. I was not too impressed by many of these China-made speakers and these Depusheng probably fits in that category.
Well, as they say, you pay your money and you do get what you pay for.
I was at my brother-in-law’s place some time back and I came across this very unusual looking extension plug that he had in his house. Now my bother-in-law is someone who loves getting all kinds of quirky things and this is no exception. What this does is to plug into an outlet switch and it effectively turns that wall outlet switch into a switched three-outlet switch. I am a bit leery about this because I do not think this will pass Singapore’s rigorous safety standards that most electrical plugs go through. Secondly, look at the on-off switches for the thing. The chances of this contraption catching fire is pretty high too. I think my brother-in-law kinda cottoned on to this because he does not use it anymore. It was shoved in a corner, unused. Good for him I think. Its better than having his home going up in smoke.
I made the horrible mistake of buying these black China-made XLR plugs. Yes. I know the saying…you get what you pay for. Honestly, I had good fortune with some other China XLRs but these…stay away from them. What is wrong with them? Well, first of all, the lock holes do not catch. One of them came loose during an event I had. Also, when soldering them, the pins got hot and melted the surrounding plastic. I promptly got rid of them and bought some Neutrik ones…at double the cost. So remember, when making interconnects…stay away from these made-in-China black ones!
I have to admit…for the price, these China-made laser lights are pretty good but there is a warning…like all lasers, do not look at them or your eyesight will be severely affected. There are places in Singapore that need you, the owner of such lasers, to have them licensed. I personally get a headache looking at these lasers and as a result, I do not buy them nor wish to own any of them.
I came across this post in an online forum here. This is rather frightening becuse there are quite a few electronic shops here that stock capacitors like these and the last thing you want and need is getting short-changed with a couple of fake capacitors like these. Not only are their values lower than stated (because of the smaller capacitor hiding in the shell of the bigger one) but they are dangerous! As one person said in the afore-mentioned forum:
Take a look at these capacitors. The outer can says 6800uf/50V but they are actually 2200uF/35V on the inside. Insufficient capacitance at least; and a blow-up if used in a 40V power supply where you might have thought you had a sufficient safety margin!!
Scary stuff indeed. So if you DIY your own projects, be very careful about where you buy your capacitors from.
I am seriously looking at line array speakers to beef up my rental business and these babies look the part. I have been quoted a great price by a company in China (yes, China speakers again) and these ones look pretty good on the specifications, and also the price is quite competitive too. Looks like more planning is in the works. But line arrays are the wave of the future and I gotta ride that wave.
