Peltier Module Cooling

at 11:33 am. Filed under Educational, Electronic Hacks

 

If you have a project that needs some cooling you might want to look into using a Peltier Module. RimstarOrg found one in an old water cooler, with a bit of disassemble he found a system that consisted of a 12 volt transformer which feeds a small board which coverts it to 12 volts DC that the module needs and finally there is a small circuit which measures that actual water temperature to switch off cooling power when the water is cold enough. By disabling the temperature sensor he was easily able to freeze some water on the module in no time. You can see the full details of the experiment here.

Reverse Engineering a RGB LED Bulb

 

If you have ever wondered how one of those RGB LED light bulbs work have a look at the article that has put together. By monitoring the IR LED of the remote he was able to snif the IR remote codes for the functions. Once he knew the IR codes he used an Arduino to run through all of the byte sequences but unfortunately there were no easter eggs IR codes in the bulb. Since one side of this bulb has line voltage you must be very cautious when hacking it. Chr demonstrates how he works around this danger.

Fairchild 1967 Briefing on Integrated Circuits

at 6:17 pm. Filed under Educational

 

Funny how they look at the circuitry from the 60s and call it old fashioned. Interesting how we work with these little pieces of magic every day without having to know the complexity that goes into creating them. Other than automation I don’t think much has changed over the years. I wonder if someone sent them a letter at the address shown at 19:08 if they would get anything in return?

“Fairchild Semiconductor Corporation was one of the most influential early high-tech companies. Founded in Palo Alto California in 1957 by eight scientists and engineers from Shockley Semiconductor Laboratory, Fairchild Semiconductor Corporation was funded by Fairchild Camera and Instrument Corporation of Syossett, New York. Rapidly establishing itself as a technology innovator based on its invention of the planar manufacturing process in 1959, the company developed the first monolithic integrated circuit, the first CMOS device, and numerous other technical and business innovations. French oil field services company Schlumberger Limited purchased Fairchild in 1979 and sold a much weakened business to National Semiconductor in 1987. In 1997 National divested a group, formed as the present Fairchild Semiconductor, in a leveraged buy-out. The company re-emerged as a public entity based in South Portland, Maine in 1999 under the corporate name Fairchild Semiconductor International, Inc.”

WaterColorBot

at 2:53 am. Filed under Cool Gadgets, Educational, Electronic Hacks

 

Check out the cool WaterColorBot. It was dreamed up by Super Awesome Sylvia and helped to be created by Evil Mad Scientist Laboratories. I can see this be a great project for older school kids to put together and have the younger school kids use it. The Kickstarter has been funded so this is something that we will be seeing around. The robot is built from CNC router cut plywood that also got a great looking laser etched name. There is a bit of assembly but looks like it would go together quite quickly. I can see this cranking out some cool designs over and over to be sold at school events to raise money instead of selling cookies or washing cars.

Nintendo 64 Game Console Teardown

at 10:09 am. Filed under Educational

 

Dave from the EEVBlog does a Nintendo 64 Game Console Teardown. Looks like Nintendo figures the regular security screws such as torx was not worthy of their housing. They have used some crazy security screw that I have never seen before. It didn’t hold up to a drill with a large drill bit though! I am surprised to see how much metal there is on the inside. Next time I need a jack stand for my car a spare Nintendo 64 would probably work out. :) The EMI shielding is quite impressive on this thing. The chip count is surprisingly low in this thing, there is a CPU, a GPU, some memory and a handful of small external chips for things such as audio. Interesting how most of the PCB traces are rounded. Surprising to see that there is no protection between the game cartridge and CPU.
