July 2001 News
July 31, 2001
July 31, 2001 - Well I am now at the point where I cannot go any further until I get the DC-DC converter in the mail. I hate waiting. I have added a second player game port, speaker, installed the battery casing... I am almost finished. Now I have started to think about my next project. Should I make another NESp, or should I make a portable SNES.
July 30, 2001 - The casing is almost done. All I need to do is attach the battery packs, and maybe a cosmetic addition. Once that is finished all I need to do is finish the few wiring connections (Speaker), and the NESp is finished! I am still waiting for my DC-DC converter to come in the mail, so till I get it the NESp will not be finished.
July 29, 2001 - I have finished the controller for the NESp! As you can see I used two original controllers to make the controller. It works very well, as well as the original did. I plan to place a strip of contact paper to cover the screws. Of course I still have to put the screen on, which I plan to do Sunday.
July 28, 2001 - I also ordered a DC-DC converter to drop the voltage on the power supply from 12v down to 5v. Here are some links and info on what I bought.
Mouser Electronics- where I bought the IC
Manfacturer of the IC
Fact Sheet on the IC (PDF file)
Page from Mouser's catalog (PDF file)
July 28, 2001 - Here are some other LCD displays and also the one I bought, this is for anyone who is looking for a display.
Hitachi camcorder LCD —» 164KB
JVC camcorder LCD —» 231KB
Santeca LCD (I bought the cheapest one here) —» 193KB
Fact sheet for a Sharp LCD display (PDF file) —» 116KB
July 27, 2001 - Today I am working on the controller for the NESp. I was going to make a controller from scratch, but I have changed my mind and have decided to use 2 original controllers. I will use the dpad from one, remove the IC from its board, them connect the dpad connections to another via ribbon cable. in the process I connected left to up, down to left, right to down, and up to right. This will allow me to rotate the board 90° to the right. This is necessary for the dpad to fit in the casing.
July 26, 2001 - I almost brought myself to tears last night... ...I decided to cut about a half an inch off one end of the NES board. I took out my dremel and first cut the end of a busted NES board I had. It worked well and was easy. I decided to cut the prototype so it could fit in the case. So I cut it and I plug it in and the picture is screwed up! I thought I broke the board! I took a look at it later today and I was that I had missed soldering one of the pins that connected the cartridge connector! I soldered it and it works like a charm!
Above: Here is the piece of circuit board I cut off my NES.
July 25, 2001 - I am at the next step, the power supply. I need to find a good 12v battery. Then I have to make the circuit to drop the voltage down to 5v for the NES.
July 24, 2001 - The guts are together! Below are some pictures of the whole thing running. I am past the most difficult part, all I have left is to fasion a controller for the case, and fix it all together.
July 24, 2001 - I figured out how to get the composite video signal directly from the NES motherboard I found a web page that showed how to get the Video from a top-loading NES. I figured that it is probally the same on the side loading NES, so with a slight modification I was able to make it work.
Above: Here is a picture of the amp I made, I attached a stereo jack so I could easily plug it into the LCD monitor.
July 23, 2001 - I finally got it!!! WOOO HOOO!!! Below are pictures of the LCD monitor. I hooked it up to 8AA batteries and my NES, and boy is it big and beautiful!!!
Above: Here are pictures of the packaging
Above: Here are pictures of the screen running, I haven't removed the protective plastic screen cover. I will remove it when I finish the unit.
Above: Side views of the screen. The rear circuit board can be removed and placed in a diffrent location.
July 22, 2001 - Check out these pictures! Here you see my NES running on 4 AA batteries, it's RF modulator removed, and a newly soldered cartridge port, allowing games to be connected without the stock connector! I am still waiting for my LCD monitor (I am going nuts!)
July 22, 2001 - I bought a Project box from RadioShack that I plan to use to make the casing for the NESp. part # 270-1809 price: $6.99 I also have decided to skip the whole ribbon cable thing and solder a cartridge connector directly to the NESp board.
Above: picture of or my modified NES board with its new cartridge slot.
Above: picture of the project box I bought at RadioShack that will be the casing for the NESp
Above: picture of the project box with the NESp board in it. I plan to cut about an inch from the right side of the board. This will allow it to fit in the case better.
Above: pictures of my meaty mitts holding the casing.
July 21, 2001 - Correction: I was informed that the Game Gear games are not compatible with the SMS There was a hardware upgrade that makes it so Game Gear Games don't work in the SMS. It's like how GameBoy Color "only" games won't work in a regular B&W GameBoy.
July 19½, 2001 - I am waiting for my New LCD monitor I ordered... The waiting is unbearable! Well while I wait, check out these links!
July 19, 2001 - Play Game Gear Games on you Master System or Genesis? I have always been curious as to if it were possible to play Game Gear Games on a Master System. I own a MasterGear converter which allows Master System Games to be played on a Game Gear. So today I opened the case and discovered what I always thought -- the converter is just a ribbon cable that adapts Master System Game pins to connect directly to a Game Gear. So I would have to say that there has to be a 90% chance that the reverse is possible. I personally would like to play my Game Gear Games on my Genesis through the Powerbase converter! Even better, plug a Powerbase converter in my Nomad and play Game Gear Games on it :-)
July 18, 2001 - Monitor purchased! I just bought the LCD monitor I wanted, and it was cheap! Click here for details and to order your own! You cannot beat 383(H) x 234(V) resolution!!!
July 17½, 2001 - Game Gear News The Game Gear I bought earlier today is not compatible with the TV tuner. No Problem I still have the original 1990's Game Gear (not that I would hack it apart). Hey for $30 it still is not a bad deal!

Above: Sega Nomad (Very Cool! Star Control in it -- even cooler!)
July 17, 2001 - Bought a Game Gear! I bought a Majesco Manfactured Game Gear at Toys R Us for $29. I wanted to see if I could use a game gear screen for my portable NES. After I bought it, I found out that the LCD display I originally wanted had dropped in price to $80!!! So I am going to buy that!
Anyway, in my search to find out information about the Game Gear's Video I found this article in #33 of Electronic Gaming Monthly. It does the reverse of what I want to do but I know several people who would like this article.
July 16½, 2001 - NES Schematics found Cheaper! I have found the exact same NES schematics that I bought for $15 on MCM electronics web site on Electronix think I should scan it and post the schematics here since the schematics are copyrighted. They also have schematics for the Gameboy, Genesis, SNES and more!
July 16, 2001 - Isolatated the RF modulator from the main board! I have found a NES for $20 and have started work on the system. I desoldered the RF modulator from the board and reattached it through a ribbon cable. I am continuing my research and will try to eliminate the need for the modulator.
Here it is running
Here are some shots of the modulator which I hope to be able to eliminate
