This is my new laser pointer with Sony SLD1239JL diode inside.
For housing I have used a 4 x AAA powered dorcy.
The laser diode is driven by LM317 based driver circuit and is set at 200 mW of light output.
I have used an Aixiz glass lens instead the common acrylic lenses to collimate the laser beam, to obtain more mW.
It has a good burning power, and it can burn a hole in a CD case in a few seconds.
I have made the heatsink (that is also the head of the dorcy) with the turning machine and I have inserted the Aixiz laser module into this.
This laser has look like a Hulk Ultra.

Looking for an easy way to display your system information on your Mac? iStat nano adds a widget to your Dashboard, so all that info's available with one click, and Veronica shows you how it works on today's Tekzilla Daily.
In the first episode the PCKicks Computer Help Force, Computer Support Specialist Tom shows a way on how to clean out one of the most important parts of the computer to prevent overheating.
In this part of the tutorial we will show you how to correctly mount a CPU fan and heatsink to the motherboard.
for high resolution viewing.
We found an oldish system and took all the heatsinks out. Then we overclocked the 64mb graphics card without its heatsink untill it started sparking and melting the power cables. Eventually we took it outside for it to burn.
You’ll get masterful cooling with the new Cooler Master Hyper 212 (Model RR-CCH-LB12-GP). Designed for Intel LGA 775 and AMD’s AM2, 754, 939, and 940 processors – the Cooler Master Hyper 212 boasts a heatsink with a Copper base, Aluminum fins, and four (4) heatpipes, and 2000 RPM fan speed, with 69.69 CFM fan airflow. With its 50,000-hour life expectancy and 19-dBA noise levels, the Cooler Master Hyper 212 delivers long-lasting performance and much-needed silence. Cool your system with the Cooler Master Hyper 212.
The EVGA GeForce GTX 280 graphics card rips through DirectX 10 games at blazing fast frame rates and enables realistic physical motion and massively destructible environments with NVIDIA's new PhysX. technology. And that's not all. The EVGA GeForce GTX 280 graphics card also supports extreme HD (2560x1600) resolutions, and gives your system the power of up to 240 multi-threaded processor cores, offloading the most intensive processing tasks from your CPU to your Graphics Processing Unit (GPU). The special Hydro Copper heatsink attaches to your existing liquid cooling system to allow extreme overclocking.
Today DFI has stretched the boundaries with their executive LANParty DKX58 Nehalem Motherboard which supports LGA1366 socket CPUs from Intel's all-new Core-i7 processor range.
This LANParty DKX58 motherboard has plenty of features that will allow you to tweak and fiddle until you have your system purring to your satisfaction.
Like the Audio Realtech ALC889 chip and the LAN Chip, which is a Marvel 8053 and gives 15% better LAN speeds than other integrated chips.
The Debug LED helps when things go wrong and 33 different codes to tell you exactly where the problem lies. The Power and rest buttons are also very convenient.
The X58 chipset allows three graphic cards PCI 2.0 slots, for three-way SLI or CrossFireX setups, supporting a 16x, 16x, for 2 cards in tandem, or 16x 8x 8x for three-way SLI or CrossFireX
DFI leave the MOSFET cooler exactly where it is needed, so it cannot be detached, but for the enthusiasts, they allow the Northbridge heatsink part to be removed, but not completely. There still remains a protective copper plate which can accept any kind of cooling device as needed. The copper plate conducts the very cold cooling from LN2 or dry ice directly to the MOSFETs through the specially sintered heatpipe, or alternatively offloads heat as needed.
What should also be noted is that the Sintered heatpipe is very unique and not found on other brands of motherboard. It has much more liquid inside the pipe and with a thicker porous rim, it transfers heat in a very effective way, the same way that a sponge works when absorbing water. This allows the heatpipe to be oriented in any position and still work effectively.
Next is the number of fan connectors to be found throughout the motherboard. In total 6 headers are available and each can be monitored directly through software in the BIOS.
The digital PWM can be monitored and controlled to some degree via a GUI called Smart PWM in a windows. The motherboard automatically senses work load and activates 2 phases for idle load, and 6 phases under full load.
ABS or Automatic BIOS Settings, DFI have preprogrammed the BIOS in this DKX58 motherboard to accept an automatic overclock.
Just press F1 when you start up and the BIOS will do the rest.
The CPU, memory and other components are automatically boosted, and in some cases can give 20% performance boost. Perfect for enhancing your PCs performance without having to know too much about overclocking.
When you want to reset your bios, most modern high end motherboards have some kind of switch or jumper to do this. Some are inside the case, some are outside on the back panel. DFI have taken this a step further. If you press the reset and Power on button simultaneously, then your BIOS is essentially cleared. No need to reach around the back of your PC, just press together and you clear your BIOS.
Similarly on the DKX58 motherboard DFI have utilized two buttons which are pressed together to clear the CMOS if you are benching without a case. This adds to safety.
This motherboard is packed with features, most of them are based inside the BIOS, and going through them briefly you can see some of the new settings and what they are for.
Essentially there are two levels of BIOS, one is called Genie BIOS and is for you guys who know what you are doing. The other standard interface is for those who prefer standard settings or automatic OC without too much hands on tweaking.
Here you can see a very quick overclock via the Genie BIOS, and the bus speeds before and after so you can judge the boards capabilities for yourself.
Without a doubt DFI stand alone when it comes to BIOS settings and tweaking options since there are over 100 unique settings available.
This motherboard really is a work of art. Having met the guys at DFI, seen their commitment and attention to detail as well as witnessed their passion at creating the ultimate motherboard with the most tweak ability

Dust can clog the fans and heatsinks of notebooks. When it does the fan will spin more often and louder than it used to. This video shows how to access the fan in a Dell notebook and then clean it.
After we cleaned this notebook, the fan only started spinning when the notebook was working hard, as opposed to all the time.
This is my Dorcy JR blu-ray laser.it uses a flexdrive v4 at 120mA, darkhorse heatsink and a PHR-803T blu-ray laser diode.Enjoy the video!
