General discussion / Re: I just bought this, and you what did you buy ?
I ordered 5 different items from Amazon.co.uk, total 6 items, so two pieces of one item.

Now I got delivery information. I will get 3 Parcels from Royal Mail, and one from DHL. I'm wondering how my sub-£30 order gets this kind of delivery :D At least I'm having fun time to fetch packets from post office and opening them... LOL I must say.

Edit: More on topic: I bought used Buffalo Linkstation (Linux NAS box) without HDDs for 6€. I'll be hacking the box to turn it to NAS/irssi/http?/etc-box :)

General discussion / Re: PCB kit: SMD or TH
As a person who doesn't have any SMD parts, I would like to buy a kit with all parts included. When I'm more comfortable with SMD, I could buy the parts as larger quantities. I understand the stocking problem also. But you could sell the parts with the board, reasonable priced.

Project logs / Re: Teardowns
Thank you for your advice, hak8or, but I've been asking a budget for a tripod some time... Not successfully yet. I'd rather not buy the cheap little ones, so it is somewhere like 50 €... I follow the prices regularly :)

I added description in every picture now, thanks for the advice. I also tried to make the order more suitable to people who haven't seen the actual device.

Nice to hear you are curious about the C2 and his friends, there are at least three of them, two big and one smaller. I have no clue what they are, just some sort of capacitors, and there seems to be seven sets of metal layers...

Thanks for trying to help with the ebook reader. I know the CPU is undocumented, and I downloaded the firmware image from my reader manufacturer site. The image file does not have any 'strings' and there may be one gzipped (if I remember right) file, but it is XORed or something weird. I'll just see if I have enough interest in porting Linux on it. It was 40€, and it is very good for watching movies on the move.

Thank you for your offer, I'll keep it in mind if I choose to use something other than Flickr.

Edit: Don't get me wrong: The ebook reader is not very good, the sound quality is quite poor and subtitles show chinese chars some time... It is just better than my mini laptop :)

Edit2: Oh well, I didn't add descriptions, I added comments.

Project logs / Teardowns
I want to share pics of my electronics teardowns. They are not the most detailed or finest quality, but I hope you find them interesting.

Most, if not all of the pics are hosted on my Flickr account, but if you know a better way to host them, let me know. I chose the Flickr, because at my opinion it wasn't so PITA as most others I knew at the time. I've been thinking of hosting them myself (by turning my Seagate Dockstar to a server?), but I'm not sure about that yet.

I'd like to hear your opinions whether to include the images on the forum or just the links to them?

Very nice pics there! As far as I know, my LG TV runs Linux, so it is possible. I have some pictures of disassembled electronics, too. Do you want them here somewhere, should there be a thread or something for "inside electronics"?

Project logs / Re: I need help to fix an old PSU
It works even after assembling! I must find those 4 small screws to hold the cover and this project is finished! Thank you for help, I learned a lot :)

Project logs / Re: I need help to fix an old PSU
Status update: The PSU has been lying around unplugged for few weeks. Now I took the board out of the box, and...

First start: Beeeeeeeeeeeeeppp, just like before, output voltage around 1,3 Volts. Turning off. My 12V LED string (load) flashes after the shutdown.

Mysterious.

Little bit of thinking, then second start: No beeeeps, LEDs light up, output 13,6V, steady.

Switch off. And on, and off... It seems to work, when not in the box. Now lets see what happens when I assemble it again.

Just a random thought: Could you use camera to detect colors, like CHDK firmware in Canons? I'm not sure, but it could be possible to extract RGB values in the image, maybe you would need white (or just known) background...

I REALLY don't know (it it's possible), but that feature could be useful.

Hopefully you get the power supply to work!

I wish here were piles of "junk" to find parts. No, anything that uses electricity (batteries, solar power, mains...) MUST be returned to place of purchase or special electronics recycle place. And, the recycling is paid in the purchasing price, so don't expect any rewards :D
