1. I had received a hot glue gun as a present perhaps 15 years ago and never used it It was sitting on top of my shelving unit out of arms reach Now was the time to get it down and see how wonderful the gluing process can be When I was all though with the glue gun I figured that I had saved at least 2 3 hours of my time in not having to fabricate more mounting brackets or drilling more holes Believe me the hot glue gun won t be sitting around for another 15 years I used it for several items including the USB 2 0 hub figure 12 a i z 2 oa piee Hi z Sa Figure 11 Mounting the laptop to the scanner cavity with three bolts Project Scan a Tron By Allen C Haid January 2007 Figure 12 Mounting a USB 2 0 hub with the hot glue gun The final stages of the Scan a Tron case mod were focused on getting all the components to work together and also to get the case lighting worked out There are lots of ways to add light to your cases and I wanted to use both cold cathodes and LEDs As it turned out I found a new type of lighting device figure 13 Molex Lights LEDs These are made by Sunbeamtech a company known for some unique items among case modders Figure 13 Molex Lights are inserted into Molex power plugs Project Scan a Tron By Allen C Haid January 2007 These new LED lights make it easy to add some lighting effects to your Molex power plugs as shown in figure 14 I used three of these to bring a bit of green light2. Project Scan a Tron By Allen C Haid January 2007 Figure 3 The scanner chassis after removing the unnecessary components Being a somewhat experienced case modder I looked for documentation on the laptop I went to the HP website and found a service manual This is the exact type of documentation you need for laptop disassembly I want to thank my friend Jim for suggesting that I look for this type of document it probably saved me from breaking components when I tore the laptop apart Speaking of the laptop in figure 4 you can see what I was starting with ia ee le Figure 4 The donor laptop an HP Pavilion ze4145 2003 era Project Scan a Tron By Allen C Haid January 2007 The laptop disassembly went according to plan meaning the steps in the HP service documentation I knew I wasn t going to use the laptop display I already had a 17 LCD mounted to my workbench and Scan a Tron would be connected to that when I was finished But I certainly wasn t going to break the laptop display or even the keyboard I gave them to my friend Jim for his use You never know when you ll need a certain part that can t be easily purchased so he now has a few extra parts that I didn t need for this case mod project In figure 5 you can see the laptop disassembled to just the motherboard chassis components These can be easily mounted within the scanner chassis while maintaining sufficient height clearance Befor
3. Project Scan a Tron By Allen C Haid January 2007 The Scan a Tron case mod project is the realization of an idea I had over a year ago The original concept was to build a computer into an old HP ScanJet 6100C that I bought from a work auction for just a couple of bucks I had the scanner taken apart within a day of bringing it home but soon realized that it wasn t going to be deep enough to accommodate modern CPU coolers and especially graphic cards or even a normal sized PSU So I put the scanner back together and let it sit in my workshop collecting dust Fast forward about eight months and I was now looking at an old HP Pavilion ze4145 laptop that was available to me since I had just given my wife a new replacement laptop for her birthday This three year old laptop wasn t much use for anything more than browsing the Internet so I figured this was my answer to the size issues of the original Scan a Tron concept I could work around the space limitations after all Figure 1 Like a new father Allen is proud of Scan a Tron Scan a Tron was scheduled to be a holiday 2006 project meaning I would have the parts on hand and do most of the build during the last week of December This week has become my annual mod week and as long as I prepare for the work ahead of me I can usually get the job completed before New Year s Eve is history sort of a last hurrah to the current year The first step in modding is to come up with a conc
4. e I go too much further I should mention a very important step one that I performed early in the modding process If there are new parts or components that will be required the time to order them is when you are trying to visualize the completed project I knew I would require a few computer parts such as a USB 2 0 hub and a USB 2 0 Cardbus adapter but the big item was to be a laser etched window to replace the scanner s glass platen I went with the boys at Hyperkore computers http www hyperkore com etching standard html as I have enjoyed dealing with Tommy and the other guys on previous orders I submitted my custom Big Al s logo design and asked Tommy to help me with the lettering layout Tommy came up with a few ideas and in a few weeks I had my new custom laser etched window figure 6 This is the type of thing that can make a case mod really stand out from the competition Project Scan a Tron By Allen C Haid January 2007 e 1 a 7 eva 2 ef TA aT PEL TE Figure 6 My custom laser etched window from Hyperkore Computers The new laser etched window was sized to fit in the same mounting frame where the old HP glass platen was previously figure 7 The window itself had to be ground along one edge to fit under the lip of the mounting frame but this was no big deal with a Dremel tool Ilumination options for the scanner cavity would need to address my lighting options for this laser etched window and I decid
5. e case of Scan a Tron should be carefully disassembled without breaking parts that might be required later This is an area where experience leads the more seasoned case modder to find the proper documentation that will aid in the disassembly process Taking apart the old HP scanner was really a piece of cake The top cover just came right off it was designed to be removable by the scanner user and after removing four screws in the top section I had access to the interior figure 2 I realized that I needed the heavy metal frame section at the rear of the scanner as this was the support for the top section I didn t need those rails for the scan assembly and I certainly didn t need that power supply unit PSU Figure 2 The interior of the HP 6100C scanner After removing the unnecessary components I was left with the scanner chassis as shown in figure 3 I was now visualizing different mounting options for the HP Pavilion ze4145 laptop that I had yet to disassemble Would I have to remove the center section from the scanner chassis to make it deep enough for the laptop Which way should I orient the laptop itself profile or landscape Because I had already considered my mounting options for the completed project I knew that a landscape mounting for the laptop would be best but now it was time to see how far I could disassemble the laptop and thus determine how thin it could be made Height of the laptop mounting was my real enemy
