  1. I got a bag full of the second one for one of my projects. Personally I quite like them and they don't rely on perfectly machined holes :) Phil EDIT: And it is available in Red or Green as well!
  2. I quite like this quote from http://lostconservative.blogspot.com/2008/06/truth-about-realclimateorg.html I'm not saying who is right and who is wrong but there are certainly strong arguments from BOTH camps ! EDIT: This is another interesting paper: http://scienceandpublicpolicy.org/images/stories/papers/commentaries/solomon_essays.pdf Phil
  3. Hi Jooks. I would really ignore what voltage you are seeing on PIN14. You will only see ANY voltage on here if there is a PIC in the socket but you could easily interfere with the PIC operation (and even crash the PIC) by putting a meter on this pin. As Wilba suggested, definately remove all chips and then measure voltages again. As these are all fairly fragile, it is always a good idea to do this before you put any of the chips in! Cheers Phil
  4. Hi Jooks. I think you added the bit about J25 while I was replying as I didn't notice it before :) Have you tried a forum search? I just did a quick one and J25 is an unregulated DC output for a 'fan'. It should be between 9v and 11v so 13.49v does seem a wee bit high, what power supply option are you using? If you are using one with regulators on the MB6582 then I would check that these voltages (5v and 9v as you are using 6582 SIDs) are correct.... Phil
  5. Hi Jooks. I have never tried to measure the voltage across a crystal. Whatever it is on this one will be oscillating 10 million times a second so you will never get any useful readings with a standard DVM (if you had a 10Mhz oscilloscope you might see something useful). For this sort of test I would turn off the power and check the continuity between the PIC pins and the crystal, this should be enough... With U1_CORE4 Pin25, you answered your own question, the clue is in the pin name, Tx (Transmit) if there is no PIC in the socket then it can't be transmitting anything! I would expect the Tx pin to be around 5v when it isn't doing anything (if there is a PIC in the socket!) I would be a bit worried if getting a "READY" message is intermittant, that indicates a possible bad (dry) connection. Cheers Phil
  6. What an interesting site, I love the "slinky" reverb :) EDIT: Not sure about beads from a beaded seat cover used as knobs for potentiometers though......
  7. why cars weren't made to fly..
  8. Hi. I use Farnell (in the UK) for many of my components. They offer a reasonable trade-off between cost and product range and they have a reasonable minimum order for free delivery (20UKP). I don't know what they are like in Denmark but the MC2002D that you list is about 12UKP from Farnell here so quite reasonable. By the time you have added connectors etc you should easily get to the minimum order (well I always manage it anyway :) ) With the display, 2x20 is the default size for the MBSID but you could probably get away with a 2x16 (Farnell have some for about half the price of the 2x20). I'm not sure if a recompile of the sid app would be required for a smaller display? I tend to go with the biggest display I can afford (or justify) which is probably why my DMX controller has a 4x40 one :) Cheers Phil
  9. Hi. Firstly, I would recommend that you start a new thread rather than resurrecting a 3 year old one (especially as you are talking about different synths)..... If you didn't find anything in a search of the forum about these particular synths (it doesn't look like there is anything) then you may be the first person trying to midify these (with Midibox anyway) A quick search of Google reveals this site with manuals/schematics for the EM-25 which should be a good starting point. Without a full analysis of the circuit, I can't tell you how difficult it will be to midify (especially as I don't read Russian) but this should be a good starting point. EDIT: The URL of the site may help :) http://www.ruskeys.net/eng/pasp/electr25/pasp.php#ps Cheers Phil
  10. Well I left school at 16 and got an apprenticeship in Electronic Engineering at RACAL Defense Electronics. They sponsored me to go to college for 2 years and then I spent the rest of my time in the software dept, mainly debugging Ada code in IFF RADAR systems and building DEC VAX Clusters. I also spent about 6 months in the schematic capture dept using Apollo Domain workstations, most of the circuits were 6-10 A0 pages of handdrawn schematics..... When the cold war ended I took voluntary redundancy (in the early 90's) and got a job at a computer networking company until I left to setup my own networking company http://www.lansystems.co.uk with my 2 brothers in 95. I have been doing that ever since. Originally specializing in Novell Netware and later (like everybody else) Windows Servers. During most of this time I have worked 'part-time' as a theatrical sound designer/engineer and have been the resident engineer in a number of local theatres over the years. Over the last 5-6 years I have also started doing PA for a number of bands with the 'kit' that I have accumulated. I also do the odd (very odd) disco :) Phil
  11. I know it sounds obvious but what about male and female IDC connectors ???
  12. You just couldn't stop yourself could you :) :) ;)
  13. This reminds me of an argument that I had with a friend once where they said "God I really hate your pedanticness" "I think you mean pendantry" I replied. Needless to say they didn't speak to me for a while after that :) Phil
  14. I suppose more accurately, H2O2 is 'a' bleach, as in a chemical that removes colour, it isn't chlorine bleach (like you would use to clean your toilet) but it definately bleaches things :) Phil EDIT: I have just been reading about 'Oxy' bleach though which S1 is quite right, does contain H2O2 together with a catalyst but as a method of cleaning old computer equipment this looks really good!!!
  15. Welcome to the group. As a starting point I would definately look at this wiki page: http://www.midibox.org/dokuwiki/doku.php?id=midibox_sid The walkthrough should tell you everything you need. Cheers Phil
  16. The more I look at this, it makes me wonder whether a generic library for GLCD's would be a good idea, something that can draw shapes and manipulate pixels etc may be useful??? The main issue that I can see is that it would need to maintain a buffer as particularly with the DOG GLDS's, there is no method of reading data back from the display. This would need 1K of RAM for a 128x64 display (unless compression was used) which really limits its usefullness on PIC devices but I may look at something for MIOS32..... Cheers Phil
  17. Hi mrmeana. Looks interesting, I think I will do some more research on this, the only issue might be the shipping to the UK ($168.50). Cheers Phil EDIT: It doesn't look like they can ship to the UK. "This shipping method is currently unavailable"
  18. Yes I did that the first time I connected my AIN module, often accompanied by slight burning smell from pot :)
  19. Hi. It looks live everybody else ignored the last bit of your question! Have you told MIOS how many Shift Regsters you have??? in your Init() function you should have at least the following: MIOS_SRIO_NumberSet(1); // How many Shift Registers are connected MIOS_SRIO_UpdateFrqSet(1); // How often (in mS) are SR's polled MIOS_SRIO_DebounceSet(10); // How much debounce (in mS) is applied If you already have this then I would check your wiring :) Phil
  20. OK, I have committed it to svn. It isn't really finished as I am struggling to get the display of 'missiles' working. PICBASIC has single pixel Plot and UnPlot functions which I can't seem to replicate. I guess that it must use a screen buffer as there doesn't seem to be any other way to manipulate single pixels. Any suggestions on this would be welcome. It is still very messy and definately not optimized, it is almost a line-for-line copy of the BASIC version. Add the fact that it has a 1K splash screen and it almost fills the PIC :) I would be interested to hear if it works with any other GLCD's! Have fun :D Phil
  21. Hi all. Well I was at a bit of a loose end tonight and I wanted to come up with an interesting midibox project, partly to put my dog glcd driver through its paces and partly for a bit of fun. While I was searching around the Internet, I came across a PIC based space invaders http://users.picbasic.org/projects/Space%20Invaders/space_invaders.htm (written in PICBASIC !!). I wondered how difficult it would be to port it to MIOS. Well the answer is: MIOS INVADERS :o :o It is working (to a point) although porting from basic creates VERY messy code that I doubt I will clean up much but it has been fun, I plan to add midi sound (so as least it is slightly relevant to midibox!) and once I have finished the program I did wonder whether it's appropriate to add it as a MIOS app in svn ? :) Cheers Phil
  22. That looks great cimo, i'm glad it all worked ok! Can't wait to see the video..... Phil
  23. That's great news :) Compared to getting J5_IO working with C, the LCD should be a walk in the park as the MIOS LCD support is very comprehensive and has been thoroughly tested in literally hundreds of units :) Cheers Phil
  24. The only thing that springs to mind is looking at your breadboard, you have left pins 1-7 'floating'. It is always a good idea to tie them to ground if they aren't being used as they will be generating spurious values..... Cheers Phil
  25. It is now :) Phil
