While browsing the digital archives, I noticed the following pictures again.
Meanwhile, more than ten years have passed since I had to initiate the end of the television repair shop.
|Look in the old workshop
Almost at the same time as the widespread use of flat screen televisions, orders were down. Except for a few customers, who insisted on retaining the old technology from ideational values, hardly anyone could fix it. Due to wage side costs and realistic, minimal profit-oriented pricing, it was just too expensive for people. If, for example, a repair of the high-voltage power supply of a television (replacement of line transformer, driver transisor and various capacitors and resistors) a price of about 90 euros assumed, that was again borderline, almost too expensive. If one considers that for these sum the parts scarcely 40 euro in the EK cost, then for the remaining 50 euro the error had to be searched for and found, everything to be expanded and reinstalled.
The unit had to be cleaned inside (often we got “boxes that collected the dust and nicotine of twenty years”.) Also, a careful test run should be done, so what about the 50 bugs? Hired labor costs more than half of non-wage labor costs. How many devices do you have to repair during the day in order to cover your costs?
Sometimes you could see curiosities. Since one or the other owner of the TV has ever tried even as a repairer and found a faulty network backup. – “No problem, is only a backup …” Which is then wrapped in the absence of a suitable new backup and knowledge simply with cigarette paper …
|“expert” repair of the customer
“Then it works again …” which turns out to be not quite correct. After inserting “it pops and flashes” and nothing was more … So the device came to me on the desk … “Why is the repair so expensive? – was only a fuse broken – I know myself out there – I am an electrician “You can hear such sayings then.
I recently updated my home network a bit and swapped the old Netgear ReadyNAS Duo for a QNAP TS420. Since the supplier wanted to have a “rating” on the article, I indulged myself in the five minutes and wrote a few lines …
I opted for Qnap based on a recommendation from an IT colleague and because I was also looking for a new, more powerful NAS that also supports WakeOnLan.
The NAS server should be able to be remotely powered up from the road. But this only works if the mains voltage of the NAS is not interrupted in the switched-off state (for example, by a Lan-controlled power strip). Furthermore, the router must support the forwarding of the MagicPacket.
A great feature of QNAP is TV streaming to the home network. You can plug a DVBT stick to one of the three USB sockets and then install a small tool on the NAS.
The Terratec Cinergy Piranha is NOT supported.
Unfortunately, very few DVBT sticks are compatible and recognized. So if you want to use this feature: Be sure to see the website for the compatible sticks. Of the APPs that can be installed on the QNAP, there’s plenty of … OwnCloud, all sorts of webapps and servers, downloaders … Everything is available on network protocols. There is also a quota management for each share or each user.
To the noise: The noise-volume of the NAS depends only on the volume and especially the temperature of the hard disks used. Here I would recommend to use only real server disks, otherwise the SMART status of the disks will quickly display an “ATTENTION” or “WARNING”.
A problem that occurs every now and then: After booting, sometimes the web service will not start and the NAS will not be accessible through the browser. The shares are always there. However, a reboot always fixes the problem. (at least until now 🙂 A future firmware update should fix the problem. (meanwhile this problem is solved due to updates 2015)
Slowly, it is time to archive all the tech stuff you have to deal with on a daily basis and always had to do before, in a blog. Above all, when I’m in my parents’ house, I always find interesting things from my childhood and adolescence …
And since you are always on the move with a mobile office (ie a smartphone) anyway, you can try to capture these things … let’s see how far that works. The information here on the blog merely represents an ‘archival’ of small projects and events I’ve dealt with over time.
Remark: This is NOT a scientifically edited blog.
Incidentally, the picture here shows a small project with an old oscilloscope tube (Braun tube), which I wanted to bring back to life … more information will be available later.
