  1. I am considering making another run of Super 8 bit PCBs after not making any since 2016. Would anyone be interested? Unlike before, this will likely be a small production run of the bare PCBs, I don't plan on making the powder coated cases (unless there is a lot of demand.) Send me a PM if you would like one, and if there is enough interest I will begin taking preorders.
  2. I have updated the parts list for the NESessity v1.3 because several parts on the last version are out of stock or end of life. I also have NES - Neo Geo controller adapters available. https://www.ebay.com/itm/Adapter-to-use-Neo-Geo-Arcade-Controller-with-Nintendo-NES-Console-2-Player/184709166961?hash=item2b01863771:g:CUEAAOSw5FxgTNX~ NESessity v1.3 Parts List.pdf
  3. I have version 1.3 of the NESessity now available https://www.tindie.com/products/low_budget/nesessity-v13-replacement-pcb-for-nes-console/ I will also be offering the NESessity in kit form once the parts arrive. Improvements over v1.2: changes to the motherboard shape to allow a much larger heatsink for the 7805 linear regulator extra solder pads on power switch connection, reset pins, and controller ports allow Borti's A/V power board replacement to be used various trace optimizations and component footprint improvements I have installed the NESRGB and IGR mod boards. The wiring is a bit simpler as the extra 5v regulator included with the NESRGB is not needed and there are solder pads to connect the IGR mod. Since the NESessity uses the reset circuit from a top loader NES, set the "LO" jumper on the IGR. I am also working on a NES - Neo Geo controller adapter. Basically a standard controller circuit x2 wired to Neo Geo controller ports. I hope to have this available soon.
  4. I have the most active forum thread for the NESessity on shmups system11: https://shmups.system11.org/viewtopic.php?f=6&t=66487 I will try to check Atariage more often as well to answer questions. The bare NESessity PCB is available here: https://www.tindie.com/products/low_budget/nesessity-v12-replacement-pcb-for-nes-console/ I have a couple assembled NESessity PCBs currently on eBay. Youtube video for the latest v1.2 NESessity: Eventually I plan on building 25 NESessity PCBs (w/o CPU and PPU) and hope to have them ready late January 2021.
  5. I have the new version NESessity PCB v1.1 tested and working great. So far I have built a simple composite video only NESessity, and I will be building a NESRGB modified version soon. Even though there are no new major features on v1.1 over v1.0, I have incorporated many bugfixes and other improvements into the overall design.
  6. I am working on many things at the moment and really can't devote the time required to bring back the Super 8 bit. While it would be easy to just order more PCBs with the previous design, making custom parts like the sheet metal aluminum case and controller ports is very expensive and requires a large order. There are some issues with the v1.0 NESessity PCB I am working on, and I hope to have them resolved soon. I hope to have a new version NESessity PCB available this fall if things go to plan.
  7. I don't plan on designing any replacement PCBs for other 8 bit Nintendo systems at this time. The top loader NES is a lot less common than the front loader, and there would be many extra challenges. There would be less room on the PCB for any extra circuitry and controller ports would be difficult to desolder and reuse. I'm working on the next revision of the NESessity, and I'm open to suggestions. Possibly add an 8p mini-DIN connector for RGB replacing the composite RCA connector? Possibly add a SP3T switch for palette selection near the expansion port (when using a NESRGB?)
  8. Introducing the NESessity front loader NES PCB replacement. I am currently working on getting good CPU and PPU chips and I have ordered a blinking light win cartridge slot replacement so I can do full testing. I even ordered a high quality desoldering tool so I can remove CPU and PPU chips easily. Everything fits perfectly in the original case. My first build will be basic with only composite video output to ensure everything is compatible and functions correctly. I'm not too worried because I've built over 40 Super 8 Bit systems. The CPU, PPU, and connector for power/reset board must be reused from the original PCB, but everything else is new. The Famicom expansion connector is there replacing the useless original expansion slot, although admittedly it may be difficult to plug some things in without some kind of extension cable.
  9. I have some updates on my NES front loader PCB replacement: This kit will consist of the new motherboard and a RF module replacement PCB (without RF.) Some features that will be incorporated: 15p Famicom expansion port in the location of the original unused NES expansion port Famicom microphone support Stereo sound with auxiliary cartridge input Can be assembled with original RF shielding 2 reset modes selectable with jumper: NES front loader reset (with screen blanking) or Famicom style reset (cpu only) No lockout chip PPU is in identical location to original NES so any video mods that fit original will fit here Can use original AC NES power adapter or modern DC power adapter RF module replacement board has room for larger heatsink on 7805 regulator (can also be used with switching regulator) RF RCA connector replaced with composite, and R L audio RCA connectors now on right side. (Former) channel select switch is still there and can be wired for any purpose, such as palette selection Works with original power / reset button PCB I'm taking time away from assembling my Parsec supergun project working on this so hopefully things work out! It will be a simpler project than the Super 8 bit, as I don't need to manufacture the expensive aluminum cases and I don't need to worry about parts supplies as much.
  10. I have uploaded all info I have that I used to design the Super 8 bit PCB. Super 8 bit IC connections.pdf
  11. Please calm down people. I am willing to open source some of my Super 8 bit drawings and notes in the near future. I will not be sharing PCB design files. I never made a complete schematic of the Super 8, rather some hand drawn schematics and a spreadsheet of the major IC connections. As I've said before, I have no plan to make any more Super 8 bit consoles. However, I am working on a replacement NES PCB at the moment. It will not be a replica or reproduction, but essentially a Super 8 bit redesigned to fit into a NES front loader case. I cannot say for sure if this will ever be released, but I am working on it. I like the work Redherring32 is doing, and if there isn't much demand for the "super 8 bit ized" version I may scrap the idea.
  12. I no longer have any PARSEC v1.0 boards left so I did a redesign, the new v1.1 board. The v1.1 PARSEC Supergun has the following Improvements over the v1.0 PCB: Thicker 1.5 oz copper layer Wider +5v traces can handle loads up to 15A 3 unused component footprints removed controller ports now even with board edge removed unsightly jumper wire to JAMMA connector (necessary on v1.0 because I forgot to connect video ground pin 14) test and service button locations swapped some improvements to component placement and footprint design connection points on PCB for A/V modification possibilities (such as adding RGB adjustment pots) it's purple now The v1.1 circuit is the same as v1.0 so no changes there. The HAT board I'm making will work on both versions of the PARSEC. It will take me a while to assemble small quantities of v1.1 PARSEC systems and additional HAT boards. I'll need to order parts and set aside quite a bit of time, so this will be a while. I'm also working on a component video hat I will have available soon. I am waiting for some parts to arrive to complete the first batch of Parsec Superguns. Several parts were back ordered so my assembly process was delayed a couple weeks. I'm considering offering the Parsec in kit form, but I'm not sure the best way to do this. I suppose I could make up a preorder list. I have 30 bare Parsec v1.1 PCBs on hand, which I will assemble in batches of 10. I could offer the Parsec about $10 cheaper without the ebay or tindie fees. No deposit required, just send me a PM and I will let you know what number you are. I'm thinking February 17 I will have the first Parsec v1.1 Superguns assembled, tested, and available. While all I need to do is finish the assembly of the through hole components, it's still very time consuming (especially the JAMMA connector.)
  13. Added extra pictures and the controller port / kick harness wiring I used. Looking like I will have these built and tested around December.
  14. I've been working on a new project the last 4 months. I built a new design Supergun PCB that's designed to connect to most TVs with the fewest additional components, while still offering high quality RGB video for various monitors and video converters. I decided to call it the PARSEC because why not. The PARSEC v1.0 has the following features: JAMMA, JAMMA + compatible 24 pin ATX power input connector (also works with 20 pin ATX) Pushbutton on/off switch (optional) onboard -5v regulator provides up to 1.5A Power on/off switch for -5v regulator LEDs indicating presence of +5v, -5v, +12v, and standby power Built-in NTSC video converter Genesis 2 A/V connector for RGB video Composite video and s-video jacks Audio output to 1/8" stereo line out jack or Genesis 2 A/V connector stereo / mono switch Audio attenuation circuit with isolation transformers Neo Geo controller ports for players 1 and 2 with standard supergun pinout Credit, test, and service buttons Kick harness connector Buttons 4 and 5 on JAMMA connector can be disabled with DIP switches Basic button remapping option using jumpers: "select" on Neo Geo controller connects to button 5 or can insert coin I'm definitely making 10 of these. It is possible I may make more based on feedback. I might also make various HATs for additional RGB connectors such as a VGA style or 8p mini DIN. Pricing will be $120 + shipping for the basic version and $135 to add the onboard -5v regulator. Send me a PM if you would like one. Thanks!
  15. The USB ports on the Nintendo Switch dock are always powered on if it's plugged into power. I don't think there's an easy way to make an auto on/off switch for the fan. I just plug it in when needed. Here's the USB cooling fan I used: https://www.amazon.com/Yoosion-Cooling-Router-Computer-Watertank/dp/B01KTG4208/ref=sr_1_1?ie=UTF8&qid=1504146830&sr=8-1&keywords=USB+fan+40mm+yoosion The Switch gets warm in portable mode, but never feels like it's getting too hot. It only gets hot while playing in docked mode for long periods.
