Very good so far

SAMSUNG Galaxy Note 8.0 2GB Memory 8.0" 1280 x 800 Tablet Android 4.2 (Jelly Bean) Black
SAMSUNG Galaxy Note 8.0 2GB Memory 8.0" 1280 x 800 Tablet Android 4.2 (Jelly Bean) Black

Pros: Just a few words: I kept this for more than a month expecting something bad to happen. After all it was a refurbished product and it has a shorter waranty as well. Nothing bad so far. I owned a Nexus7 for a while and I obviously compared with that. Is no secret Nexus has a better harware, but I could barely notice this. Is true gaming is not the main task I use this tablet for, although I do play ocasionally. The screen is larger than my previous Nexus and this makes it a big win. I can read better and most of my work has been considerably improved. The stylus is amazing. First it is much more efficient to use a stylus instead of just your finger. Everything you do you do it faster and with more precision. On top of that this has pressure sensitivity which opens up the scene for some very neat apps. After this tablet I do not think I will ever buy a tablet without a stylus ever. Battery last a little bit less than my Nexus, which was expectable, but again this is not a serious problem. I was in doubt about Samsung apps, but now I have to admit some are quite nice. The interface is designed to improve productivity and it didn't take much to get used with it.

Cons: A better battery would make this even better. A longer warranty would be nice too. The "back" comes in your way when you write and you can touch it by mistake like 98% of the time. However turning the tablet sideways solves this issue.

A DOA excellent mouse

Rosewill ION D10 4000 dpi Optical Wired Gaming Mouse
Rosewill ION D10 4000 dpi Optical Wired Gaming Mouse

Pros: -Perfect size for my hand -Braided usb cable -attractive design

Cons: - DOA

Overall Review: I find this mildly funny, but this is the first DOA mouse I ever had. Tried to make it work in 3 computers, Windows 7 on my laptops and Linux on my desktop, with and without the drivers from Rosewill website. Nothing worked. After installing the Rosewill drivers the light pattern changed but the mouse was still dead like a brick. I really love the look of this mouse and the very important fact that it fits my hand so well, hence 2 stars instead of one. I really wanted this to work. It has extra buttons placed ergonomically enough for you to want to use them. The Newegg RMA service is great and I am returning it now. I wish I had the option somehow to replace it since I hope this was just an unlucky instance. I keep wondering if electronics shopping nowadays became some sort of a lottery, where you hope whatever you buy will actually function as it should.

good, but sensitive range knob

2-16M Doppler Radar Human Body Induction Switch Module HB100 X 10.525GHz Microwave Sensor For Ardunio HB100X

Pros: It works within the advertised specs.

Cons: - overly sensitive adjustment knob - glass may impact sensitivity

Overall Review: It works within the advertised specs. The OUT pin is pulled up to 5V. So if you want to use with Raspberry Pi you need at minimum a voltage divider with 2 resistors to lower it to what the GPIO can handle at around 3V. For those extra careful an optocoupler or magnetic coupler would be great option. Obviously you will have to detect in your code a falling edge to properly handle the motion detection. At 5V Arduino users do not have this problem and can directly connect it to the GPIO. In my case I found the sensitivity knob not very helpful. I can use it at almost maximum sensitivity, turned all the way counterclockwise. I managed to detect motion at about 12m with this setting. Trying to set down the knob decreases the sensitivity too much in my case. I also noticed glass made items in nearby proximity are having a negative impact on the sensitivity.

excellent

SUPERMICRO AOC-USAS2-L8i PCI Express SATA / SAS Eight-Port Internal RAID Adapter
SUPERMICRO AOC-USAS2-L8i PCI Express SATA / SAS Eight-Port Internal RAID Adapter

Pros: -Very good

Overall Review: Got it for a desktop computer. Since these are made for Supermicro servers I had to adapt it. It is probably the only reason I would not recommend this to everybody. If you are willing to do some work to adapt this for your case then go for it. Other than that they match the Supermicro specs and it is supermicro quality. I would buy it again in the future. EDIT: Yep, excellent quality. Still going strong after more than 1 year.

excellent

SUPERMICRO CSE-721TQ-250B Black Mini-Tower Server Case 250W Flex ATX Multi-output Bronze Power Supply

Overall Review: This was excellent for my needs. You need to read carefully the specs before jumping to buy it though. It needs a proprietary front panel cable, for reset, power on, etc. It has a good fan, not very noisy and powerful enough. You can slide the motherboard tray to easily access ports/jumpers/etc. The case is generally good quality, good cuts and overall good materials. The HDD trays are well built without the problems other manufactures have. This goes back to reading the spec. This case is small, so please check carefully what clearance you have before buying. I did my homework and I knew all of these before buying it, including what heatsink the CPU will have, how big it it will be, etc.

Pretty good

Coboc SFF8087-4SATA-0.5M 0.5 Meter  30AWG Internal Mini SAS 36pin (SFF-8087) Male w/ Latch to 4 x SATA 7pin Female Forward Breakout Cable  with Nylon Braiding

Pros: -good reliability

Overall Review: Been using them for almost 2 years and they still seem to work great. Worth to mention is I messed with them only 2 or 3 times when I had to replace some HDD, but other than that they worked under no excess stress conditions. This probably helps with current reliability. Definitely recommend them for non-production builds.
