Only days after the European PLAYSTATION3 launch and people are already taking their systems apart. Unfortunately, tadalafil I didn’t find any easter eggs on the PCB. The biggest problem should be in the absence of a hardware PlayStation2 emulator resulting in some controversy. I am not sure if it is apparent from these pictures that the chip is missing, so I will try to post pictures of the U.S. or Japanese mainboards if I can find them.

I spend about an hour every time trying to find my original install CD and cursing Linksys. I am guessing that some other people might be going through the same process a couple times a year, so for you, here is the setup utility.

This should prove useful to designers of sample-and-hold and integrator circuits along with those who are interested in a deeper knowledge of capacitors.
Since the last post about the rotovaporator on a budget, medications
we have made some improvements. First, hospital
we added a transmission to lower the power delivered to the motor and avoid the need for any kind of cooling. Second, symptoms
we added a higher stand to allow us to sonicate the flask while rotating it.
P.S. We also have a DIY centrofuge.
In case you need to create a monolayer of lipids inside a spherical flask and don’t to spend $3000 on a commercial rotary evaporator, hospital this is the design you need. Justin Ingram and I set out to build such a device from things found around the lab for a small fraction of the cost.
The first step was to create a commutator that could support the flask and allow for the evacuation of the solvent vapors from the flask. We used a piece of Teflon coated stainless steel that was held in a piece of Delrin with a pair of Delrin spacers. We also used a planar ball bearing to lessen the friction between the stainless steel and the bushings. A piece of a 5ml syringe was attached to the other end of the tube and was then was covered in parafin. This piece was just the right size so as to fit into the opening of the spherical flask and be able to support its weight.
The next step was to provide the rotary action. We found a DC motor around the lab which was connected to a standard variable power supply. We transferred the force from the motor to the flask by a belt system implemented using a standard rubber band. Although the motor drew almost 1.5A while in operation, ampoule it did not get too hot over a period of half an hour. We are working on a thermocouple to allow us to attach a peltier device with a heat sink or just a heat sink to allow for more efficient cooling.
The main purpose of the vacuum system was to collect the solvent vapors, medicine not to reduce the pressure inside the flask. For this reason, we were able to loosely connect a pair of luer-lok adapters together to allow for them to rotate and did not worry about the poor seal. We turned on the vacume system and verified that the vacuum was good enough to take in smoke from the surrounding area and assumed that it was sufficient. The vapors that we are working with are that harmful, but it is also possible to run this system inside of a fume hood. The commercial system also has a water-cooled condenser for collecting the solvent, but it is snowing outside, so we can put something out there to act as a low-cost condenser.

Something to do on the day after St. Patrick’s day? Look at application notes. By way of looking for some video encoders to generate all of the timing signals I came across an app note for increasing the longevity of CMOS devices and another regarding appropriate selection and use of passive components. They are both a little dated but still have applicable information to ever-shrinking devices.
