+karri Posted March 12, 2015 Share Posted March 12, 2015 (edited) Just kidding. Most Lynx programmers have a desire to create a real cart. Manufacturing is a bit expensive and getting into this area also has some risks included. Today I looked in chip prices and thanks to automobile manufacturers certain chips have dropped a lot. A 2k eeprom (SER. EEPROM 24AA16T-E/OT) is 40 cents and a 512k rom 1.5€ (IC, SST39SF040-70-4I-NHE). The PBC from China would just cost around 4€ (top + bottom). This should bring the base cost close to 7€/cart. Which brings me up to the subject. In large quantities the prices are considerable lower than the prices stated above. But the minimum amount is 100 carts to get the assembly done also. I bought some chips and kicked up Eagle to create a new kind of very low-cost cart for homebrew releases. No fancy plastics i'm afraid due to cost. The basic idea is to glue two PCB's together. The lower PCB is just 1mm thick and on that I assemble two low profile chips. The upper PCB has holes for the chips and brings up the thickness of the cart to 2.6mm. After the halves are glued together you also need to shape the connector so that it does not break the Lynx. The upper PCB would also have a long hole in the style of Songbird carts for easier removal. The resulting cart would be completely flat. The hole with the chips would be covered by a game label. The cart would be green due to cost. The cart would be blank after assembly. For programming you would need a Raspberry Pi that can erase the cart and program it. On top of Raspberry Pi comes a small breakoutboard that contains a Lynx cart socket. This is kind of a Kickstarter project. I will order a small set of carts (20 pieces) and programmer boards (10 pieces). If someone feels the urge to join the project drop me a line. The goal is to create a set of 100 carts (or more) after the prototype operates properly. My reality check tells me that my creations will be counted in tens of carts - not hundreds. This cart is probably the release platform for Stardreamer (which is slowly going "where no man has gone before" - again). -- Karri Edited March 14, 2015 by karri 2 Quote Link to comment Share on other sites More sharing options...
