  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.
  13. Important updates for FreeCAD * Newer versions of FreeCAD (0.19 and greater) have fixed referencing issues. Ref: https://github.com/shaise/FreeCAD_SheetMetal/issues/18
  14. Local sheet metal laser cutting suppliers Word of mouth (In industry or friends) or local hobby/workshop groups often are a good source of such services.

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)
  16. Discussion, Tips, Recommendations, Requirements & Tools. Now there is online sheet metal laser cutting, I'm sure I'm not the only one interested in such services. Suppliers PCBWay & Ponoko do international shipping. Others like Oshcut and Xometry seem lacking in this area. PCBWay (China) https://www.pcbway.com/rapid-prototyping Ponoko (USA) https://www.ponoko.com/materials/category/metal And also local sheet metal shops with laser cutting services. At this stage, PCBWay are manually quoting jobs, While Ponoko is more automated. Tools You will need some sheet metal working software to produce the required files. I use and recommend FreeCAD with it's sheet metal workbench. It's free and there are plenty of online tutorials to get you going. For boxes you will need to supply the unfolded design. * Ponoko require an unfolded sketch in DXF * PCBWay require an unfolded STEP and an unfolded sketch in PDF Folding PCBWay also do folding, But it's expensive. For small jobs there are various small press brakes available. * 300mm vice held press brake (ebay $200). * 200mm vice brake (amazon $100) * 100mm vice brake (super cheap auto $60) Note: You will need a press brake with removable fingers for small folds. Or just use some pieces of wood and a vice to fold it that way (See youtube). I'd recommend the 100mm vice brake to start with as they are pretty cheap. Note: Vice Brakes offer some extra flexability allowing the sheet to hang to the side of the press while a fold is being made. Something I realized after getting a 300mm press brake. Materials I can only comment on sheet metal (Low Carbon Steel) Generally you will want 1mm, 1.2mm or 1.5mm thick. If you want rust protection then using galvanized sheet metal should be the same price. PCBWay also offer various surface finishes - But price may vary considerably. I highly recommend requesting TWO quotes, One with and one without surface finish. Tips Sheet thickness will affect folds both in software and in physical folding of the sheet. When designing a sheet metal box, Be sure to create the design in the desired sheet thickness. When requesting a quote from PCBWay, You will need to specify the sheet thickness in the additional comments. When requesting a quote from PCBWay, You will need to specify no folding only cutting in the additional comments. Notes Ponoko automated quoting price increases the more complex the design (eg. adding some extra holes). This is yet to be tested, But removing chamfers or bevels may help in reducing cost if needed.
  17. It may be worth comparing your read roms against the V1.0 Mame roms first just to make sure everything checks out. Also, if your roms don't have covers (or even if they do) you could erase/rewrite in case any are close to bit rot failure. eg. My Mortal Kombat failed due to eprom bit rot. The eprom itself was fine, Just the data was incorrect (rom check failure on boot). After erasing and reprogramming it with the Mame rom dump it was fine again.
  18. How many eproms are there? If not too many, then just read them all in and compare the dumps to Mame's eprom dumps. Then just erase/write the different ones.
  19. I have stumbled upon this website that archives CatVer (And other) files. You may find it useful for your builds. http://adb.arcadeitalia.net/download.php
  20. Great work. Just add a border to your PCB and ensure your fills are all grounded. Also add a board revision & logo for the finishing touches.
  21. It would be counterproductive & senseless to remove guns from farms and rural environments. I just had a (quick) read of the greens firearm policy. As far as I can read - They are not against firearms for rural/farm usage. Most of the policy seems to be against urban/city usage. https://greens.org.au/nsw/policies/firearms While I'm not a greens supporter - I also don't like the wholesale logging of pristine forest areas.
  22. Pretty good for a calibration run. Is your PCB bowed or just camera distortion? Also looks like you might need to increase track thickness on diagonal and horizontals to compensate for CNC tolerances.

  24. [updated] Reply to this thread as to why you should get this package. I will consider the best candidate to collect the goods. No PM's - Make your case in this thread. All submissions will be reviewed at the end of the year (2020). Committing donations to Aussie Arcade in your request would also be advantageous. Includes DIY Toner transfer machine https://www.aussiearcade.com/forum/a...pid-controller DIY Mini drill press https://www.aussiearcade.com/forum/a...ni-drill-press Samsung M2020W Laser Printer, Press'n'Peel Blue and various etching, plating & cleaning chemicals. https://www.aussiearcade.com/forum/a...ransfer-method Note: Laptop, Residual Current Device and IR Thermometer NOT included (I want to keep these).
  25. I have moved to FreeCAD now, Lots of online tutorials to get you past the learning curve. It also ties in with KiCAD model generation if you need to create some basic (or advanced) models.
