Trying to cool my 8800gt.

Well yeah, my BFG 8800gt OC stock fan died.. So, in desperation i strapped a intel stock fan with a shroud, plus a 60mm fan i had to cool the voltage regulator heatsink. Idle temps is 55C and load in tf2 is about 85c. stock of course. when i play crysis, temperature rises up to 98c-105. Wich is unnacceptable. This won't last long, A zalman Vf900 fatal1ty edition coming to help me out in this battle. + 2gb more of ram and a ocz stealthxstream 500w.

I've got the voltage regulator turned right down. You can't see it well, but the pressure gauge is pegged at nought. Even so the steam regulator has to be closed down to really slow the engine. Towards the end I turned the power up to max to see how long it would take for steam to build while running flat out. It took longer than the movie ;)

Using a high power laser with a voltage regulator to performance a long range audio signal transfer. In the test, due to the limitation of my room, it is actually a short range. This is the first test for the circuit. I will make some adjustments on the circuit design and perform a long range test later. Enjoy. (?) ***** Notice, you may need to increase your headphone or speaker volume to hear the result. *****

Hi all. I decided to make this guide because I couldn't seem to find one already made on youtube. I made this guide really simple for a really simple kind of person. There is also a schematic at the end. And then another simpler schematic for beginners. This driver can be used for Red laser diodes and Blu-ray laser diodes. Good luck!

powercolor HD4870 with Thermalright HR-03 GT and Noctua NF-B9 (92mm) Watch part 2 here : www.youtube.com In this video I'm reapplied the thermal paste using arcticsilver 5 (46-55°C), strangely, it perform worse than my previous Thermalright Chill Factor (44-52°C). The reason I'm using NF-B9 is for silent build. At 1600rpm NF-B9 produce 37.8 CFM airflow at 17.6db noise level, which is quite good. Depends on your build you could also use fan with faster RPM and airflow. You could also install 120mm fan to HR-03 GT, but you'll need to buy Thermalright 120mm fan clip. -Update 2008/7/15- *WARNING* : When installing HR-03 GT, make sure you install all the heat sink properly, including all *ALL* RAM and VRM (Voltage Regulator Module). In this vid I didn't install all (the one with Vitec printed on it, it gets extremely hot without heatsink). It could *PERMANENTLY* damage your card, since the HR-03 GT small heatsink itself will get hot without fan. Be sure to check your VRM temp after installing, not only your GPU temp. IMO, HR-03 GT cooling performance on the VRM isn't that good, yet no review site that cover this.

Yaw Control

I apologize for the quality and shaky hand, but the video still shows the function of a wireless data acquisition taking place in a PID control loop. The effectiveness of the control appears very poor because the servo was not fixed to the table causing the output to oscillate. The Black box contains an IMU (inertial measurement unit), power supply (battery+voltage regulators), SSC (serial servo controller) and a Bluetooth module transmitting the inertial information back to my desktop computer which calculates the appropriate parameters for PID control. The desktop then transmits the servo instruction back to the Bluetooth module, which feeds the SSC the calculated servo position to actuate. This was one of three PID control loops which were to be implemented on a small scale rotorcraft UAV for my senior project.

I bought the phidgets 0/16/16 board and then discovered I could not reverse polarity for stepper motor driving, although the board could handle the current: 2A drivers are already on the board. So I added the L298N H-bridge and a slew of too many parts. The current regulator is LM317T with 0.77 ohms across the input to limit the current draw to 1.6 Amps. You can find the wiring diagrams with the datasheets for those chips. The bipolar motor has four wires. The phidgets output block uses two direction outputs and two coil-enable output wires to control the two bipolar motor coils. I used 1500 ohm pull-up resistors on the L298 inputs. So the phidgets is actually disabling (grounding) those inputs by turning ON the phidgets output. I wish I bought a stepper add on board. It would have been easier. Here is one: www.robotshop.ca

Lego walking dragline

Video taken of me operating my 1:44 scale Lego model of a Marion 8900 walking dragline. The model is still not finished, has 24000 pieces, weighs 80 lbs so far, and runs on 30 Lego 9v motors powered by 3 voltage regulators. There was no glue used in the model. (You can tell because the left shoe has actually come off the model in this video, oops) The actual machine was built in 1967 and was the largest dragline at the time. Its operating weight was 14 million pounds, it had a 250' long boom, and dug with a 155 cubic yard bucket.

Homemade Power Supply This is also good for voltage regulation/stabilization of some "green energy" voltage sources that may fluctuate/vary a bit and you need a stable/steady voltage souce for a project. I will put more text here soon, and check often. The LM317 chip allows for a low number of parts (maby 7 parts, plus cords and.or boxs) to be required to make a fixed or variable voltage/power supply. There are similar chips and I will try to put some numbers up. The chip itself is fairly large - this is not a small IC chip that is difficult to handle , and there is only 3 large terminal pins that are easy to access and work with, and a hole for the screw/heatsink if used. For the power supplies in the video, the chip is rated at about 1.25V to about 25V and 1.5 Amps of Current. There are some LM317 versions that will allow more or less current also. You can get just about all the parts at Radio Shack, but their prices are high it seems. Radio Shack is good if you need something right away. You can order the LM317 IC chip from major suppliers, and on Ebay for a deal - some already heat-sinked on a board and ready to go. If you can pick up several at a time to save on shipping, etc. They are only about $1 US now. You can even use machine screws or speaker-jack screws for the input and output terminals. Radio-Shack also does have some nice electronic "kits" with easy hook up springs for the wires. These are the popular "100 in 1" or "200 in 1" , or "300 in 1" type kits ...

This is a video showing you how to strip a technics 1200/1210 back to its face plate. The reason for doing something like this is either to pain the face plate or to replace it, in either case stripping the turntable back to the face plate is required. Just as an experiment I phoned my local electronics repair shop to get a quote on how much he would charge to do this and he said 20 quid setup charge 40 quid to strip it and 60 quid to put it back together 120 QUID !!!!!!! Thats like 170 dollars I could buy a second hand turntable for that alternatively 85 quid to simply change the face plate thats like 120 dollars, so you are defiantly saving a bomb by doing this yourself. Its not massively difficult you just have to have your head screwed on and pay close attention to where all the bits went, if you think about it the main circuit board, the power circuit board, and the transformer are all joined so youre not going to put them back in the wrong place and you know where the tone arm goes and the pitch fader, and if you have ever switched on a technics turntable you will know where the power switch is, so you cant really go wrong. Information. When soldering on these turntables especially the older models leaded solder is normally used so keep your soldering tip clean after soldering, and mind your fingers because sometimes leaded solder can bubble and it spits and itll burn your fingers. This link is for more detail on removing the screws from the bottom of the turntable ...

We caught up with Jay Leboff and talked about NRG Dock Personal Solar Solutions @ nrgdock.com. This is the first green solar product I have seen that is specifically targeted at re-charging your portable devices. The idea for the product was hatched after he was without power during a storm for several days and needed a way to recharge his cell phone and other portable devices. This product line works with those in rental units or who own a home of their own very clean and slick this is probably one of the most innovative solar products I saw at the Consumer Electronics Show 2008 From their website "NRG Dock's® photovoltaic cell charges its power station, storing energy for whenever you need it. NRG Dock's® regulator ensures the proper voltage for powering and/or charging personal communication devices - including laptops."

LM317T

Saturday, March 6, 2010

The pin that would normally connect to the 3.3v output of the FTDI chip on the official Arduino boards actually connects to 5v on the 5v Sparkfun board! While this is more of a Sparkfun issue, theres another side effect, if theres a voltage difference between the FTDI chip and the regulator, it's quite possible for the regulator to cause harm to the FTDI, this, in my and my dads opinion really isn't a brilliant idea In the video you can see I cut the track between the 3.3v regulator and the 3v3 pin, this allows the system to run perfectly.

This is the introduction of the "Trinity Screw Cell". Important Disclaimer!! This is a work in progress. I am still identifying issues and working out solutions. This is NOT the 'hey, I finally found the cure to all HHO problems' solution. ===== This is 3 Screw Cell cartridges wired in series. 12.5 VDC applied to entire assembly. Voltage drop of about 4.166 VDC across each cell. Total amps is currently about 7.5 after the cell pack had been warmed up for about 15 minutes. I am looking to increase the amperage to about 20 amps total draw. The intent of wiring 3 cells in series is an attempt to manage heat distribution more effectively without the use of a PWM or other current/voltage controller. Please note that I may go back to a parallel arrangement of these three or more cells once I have acquired some sort of Pulse Width Modulated (PWM) controller or other device to manage the current flowing within this circuit. This current configuration is set up for unrestricted brute force using only 12VDC automotive system as the voltage and current regulators without a PWM.

Laser2

Ecco un laser da 300mw creato riciclando un masterizzatore DVD non funzionante, e l'ottica di una vecchia fotocamera da 35mm. Il driver usato è lm317t anch'esso recuperato da un vecchio gruppo di continuità ed assemblato su una nuova scheda. L'assorbimento è di 400ma. Here is a burning red LOC laser that was assembled entirely from recycled materials and a bit of ingenuity. The laser is from a now defunct DVD burner (LG 22x). The driver used is based on the LM317 IC. The lenses are from an old 35mm camera (non digital). The electronic parts were recycled from an old ups unit. The output is roughly 300mw with this glass lenses and the current is 380-400ma.
