  1. I bought this also, I'm happy with it's operation. No melting issues yet, But something to be aware of is the AC wiring is wrong. Was looking at some reviews and this one mentioned the wiring, So I thought I'd check mine - Thinking it'd be fine. But nope - AC active was running to the transformer rather than to the main switch. Still operational, But not 100% compliant or safe.
  2. Bitcoin (& variants) is NOT a Ponzi scam, It's something new and different. It's only going to become more ingrained in our digital economy. However it IS a "Number go higher" scheme. And until it's "Value" is tied to some real world value (Human or otherwise), It's going to be as reliable as paper in the wind.
  3. It's easy to make claims while the bubble is expanding.... But do you trust it? Would you lay down 100k of your own money? At what point does the bubble burst and a handful of people cash out but the majority are left with worthless coins?
  4. I made 10k last year noodling round (Not really following the market) with bank stocks (ASX). IMHO Bitcoin is here to stay, It's not really tied to any actual real world value - So it's wild nature is driven by human influences. Would I put money into it? No. Your going to get more stable returns from actual stock markets or things tied to real world value.
  5. Could you take it to a local Laser Cutting company and laser cut a hole through it? Added: They cut stainless, carbon steel etc. Also Water jet cutting (aluminium, stainless, copper, hardened steels, rubber, plastics, composites, ceramics, glass, insulation, foam, leather and armour plate).
  6. You would need a PC and shipping NSW --> QLD @Jed is selling his VP for a good price. https://www.aussiearcade.com/forum/trading-forum/for-sale/for-sale-pinball-open-for-posting/2191973-750-genuine-judge-dredd-cabinet-virtual-pinball-machine-2-x-40-lcd
  7. Originally I created predefined modes, I have some vague memory that I ended up with about 35 modes. If you have only 5 or so modes (Like ArcadeVGA used), Then speeds can vary 2% fast or slow. It's when the game core runs slow that audio pops are most noticeable. I generate them dynamically, Though my target resolution is always static and the refresh is the only variable (Mame is very good at scaling). This relies on Mame versions 0.107 & greater that are able to output XML on a per game basis. Basically, 0) Run Mame/Game in -listxml mode 1) Read the game refresh from XML 2) Run cvt or gtf to build a modeline 3) Create & Activate the new mode 4) Run Mame in sycrefresh mode 5) Activate a default video mode 6) Remove/Delete the mode 7) Return to Attract Mode If your unable to create video modes on the fly, Then I think you should be pretty good with 40 predefined modes. What happens when you try to create modes on the fly?
  8. Just to note, Some games refresh rates have been corrected in newer Mame releases. So What an earlier version reports may be different to what a newer version of Mame reports.
  9. Sorry, Only just noticed this thread. Been awhile since I made that post, So it probably needs some corrections. I do have a bash script that gets the refresh rate from a list of (200) games. You can use your own list of any length with the script. (It requires "xmllint" to extract the refresh rate) Here is the output in csv GameRefresh.0223_R001.txt #!/bin/bash # Read each line of a text file # Set Mame version mame_exe="./sdlmamearcade64.V0223.Mainline" if [[ -z "$1" ]] then # Empty echo "file_list.txt required" exit fi # Get filelist filelist=$1 # Iterate through input file line by line while read rom_name do # Read Game Refresh Rate rom_xml=$("${mame_exe}" -listxml "${rom_name}") game_data=$(<<<"${rom_xml}" xmllint --xpath "string(//display/@refresh)" - ) echo "${rom_name},${game_data}" done < "${filelist}" # Finished

  11. Conclusion PCB Way provides competitive pricing (Ask for better quote if initial quote is obviously too high) and is a good option if local suppliers are unavailable. Both Hygrade Laser Profiling and Laser Wizard quote reasonable pricing providing some local supplier flexibility if QC or other issues arise. Courtesy email If a supplier has taken the time/trouble to provide you with a quote, Then be sure to respond to their quote in a timely manner. Thank them for their quote and inform them you will contact them by the end of the week if you wish to proceed.
  12. Available on ebay for aprox $10 each. Just a heads up on these cheap Chinese power supplies in case you were thinking of using them on any projects. As on any cost cutting cheap product, Components are minimal and often run hot which causes failure. Beware, When these fail they cause a short across the mains which is quite spectacular. I had two fail (spectacularly) before I realized a bad diode was shorting the 5v line.

Be sure to include in the request if you require folding or not. Some suppliers may assume you do and quote with folding included. Larger industry suppliers often have a minimum order value (Example $250). Note these and go for the more flexible suppliers.

To me $10 au per unit + shipping for low qty (x10) would be a very good price. The current PCBWay price $25 au per unit still seems expensive but doable. Pricing of $40+ au is just too expensive for what really is not a big job. I'd expect cost would be $1 if producing thousands of units direct from a china manufacturer. (This is just a guesstimate for 295.5mm x 278.9mm x 1.2mm sheet cut)
