bump!

Sold some of the caps and knobs, LPC and Rean knobs still available. Thank for the tip jojjelito

Embedded Artists LPCXpresso LPC1769 Rev C board - $30 shipped Purchased for the MIDIBox Seq 4 project but never ended up using. 20x Rean Black pointer knobs - Make an offer! Purchased from sempervirent. These are round shaft Rean knobs with a white pointer. US shipping preferred but I'm willing to ship internationally. Shoot me a PM or email or reply to this thread.

I'm hoping someone can point me in the direction of the correct ethernet port part to used with the LPC17 board on the SEQ4 project. I've purchased 2 ethernet sockets so far and neither has aligned properly to the PCB (the pin orientation is correct but some of the extra through-hole points do not align). I'm hoping to order the part via Digikey so I would appreciate if someone could point me to a specific correct part that they sell. Thank you!

Oh snap! Is this still available? I've been looking to get one of these cases and panels for a long long time! EDIT: I'm gonna put my name on the Batch #2 list just in case.

Yup, LPCXPRESSO board still has the programmer connected to it and I don't have it plugged into anything else at the moment. Just standalone.

Yes, 5.2.6 is the IDE I've been using since I tried using the newer versions and the FreeRTOS projects were not in the templates. Any ideas?

I've been scratching my eyes out trying to figure why I can't load the MIOS bootloader onto my LPC board. I've tried using the LPC IDE on some of my other machines but had no luck getting them to communicate with the LPC board via USB. I plugged the LPC into my Windows 7 laptop today and I finally got the Program Flash window to pop up successfully. Now when I try to flash the LPC I am getting an error in the IDE software, "Target is not marked as debuggable". I've read a few posts here that suggest trying different USB cables and I've tried 3 different ones so far with no luck. I've also tried playing around with some of the debugging options in the IDE, setting debugging to "none" in the Perspectives panel, also toggling Vector caching to True as NXP's documents suggest, but neither has fixed the issue. The only other option I have to try is installing a newer version of the IDE software (I'm running an older version, 5 I believe) but I'm really upset at this error message! Any suggestions on how to fix this so I can flash MIOS onto my LPC board would be appreciated. Thank you!

Yeah I'm seeing the STM32F4 and MIDI I/O boards available on SmashTV as well. Hope to see a better picture of the boards pop up online so I can get a better idea of the layout. I don't think the boards have a place for a USB port. I'd order one now, but I put my name on the list of control surface PCBs/kits and want to get all my SmashTV PCBs and parts in one order.

Ahh thank you very much Tim! I'll be buying a few other parts from you with that order, but I'll wait to hear back when you've gotten to me in the queue. Name added.

Yeah I love SmashTV, only thing is that the wiki page I linked to has buying options for both the control surface PCB (which Smash sells) and a control surface parts kit (which I don't think he sells). I have no problem sourcing parts on my own but I would prefer to buy a kit if it was available and the price was right.

Is there a particular method to adding my name to the Control Surface PCB and kit list on the wiki (http://www.midibox.org/dokuwiki/doku.php?id=wilba_mb_seq_pcb_bulk_order)? I can't log in to edit the page at all :(

I'm about to embark on a SEQ V4 as well and am wondering if there is a good resource or thread for reading up on how this project has changed in recent months due to updated hardware options. From reading another thread in this forum I see that the makers of the LPCXpresso board have made a revision such that the LPCXpresso and the MBHP_CORE_LPC17 board don't fit together nicely without some modification. Other threads are mentioning that a faster board with some better features, the STM32F4 is able to be used with the SEQ V4 project. Are other comments in this thread correct that SmashTV will be selling a revised version of the front panel board eventually? Would it be wise to start working on a SEQ V4 at this point or is waiting a few months until some of these newer revisions show themselves a better option?

I am at this stage in building my MB 6582 but can't seem to source a good quality cable for the control surface to main board connection. I prefer to deal with Mouser or Digikey if I can. I did find one suitable cable on Mouser, but instead of 8 individual wire strands the cable had 4 pairs of 2 wires. Doesn't sound like the right kind of cable for this project. Anyone have some recommendation for connector cable from Mouser or Digitech? Ebay?

Got a new PSU in the mail. This one is in much better condition but is still the same shape and size of the other adapter. They must be different models though since the information on the bottom is slightly different (though all of the specs are the same of course). On the 9v pin I am now reading 6.88v and reading it consistently across the IC socket, so that is reassuring. One thing I would offer for others trying to diagnose a PSU issue is to remember to put all your jumpers on the voltage selector pins on each SID before testing voltage. I realized I didn't have them on when initially testing :| On a related note, I was able to test my LCD module with the powered main board today and it looks like it's working alright. After adjusting the contrast I saw a single character (u) in the bottom right-hand corner of the LCD. The main board and control board are not yet soldered together so I assume this is just a test character (or I've done something very wrong).

I came across the MIDIAlf project (http://midisizer.com/midialf/) a few weeks ago and have been interested in maybe purchasing one. It's an 8-step sequencer with a couple of neat functions, but it seemingly borrows a lot of features from the MIDIbox SEQ as well as some things from the Mutable Instruments MIDIpal. The SEQ is 16-steps obviously and has a lot more bells and whistles, but I was wondering if anyone had come across the MIDIAlf project and could compare the two for me. A $50 build is intriguing vs a $600ish MIDIbox SEQ. I will probably end up with both :).

Yeah, even when in AC mode the digits on the multimeter don't move

Plugged in the PSU so I could test the outputs on each pin. It was difficult to keep the probes on my multimeter steady enough to get consistent readings, but I am only seeing power on the 5v pin. Pins 6 and 7 (9v according to the back of the PSU) give me negative readings, so I guess I just have a bad PSU :(. Maybe someone in the For Sale section has a legit power supply for PSU option A.

Today I completed my base PCB for the MB 6582. I only have 8505 chips so I went with PSU option A. I tested the board voltages for the first time this afternoon and got proper readings for all the 5v pins on the SIDs, COREs, etc, but when I've tried testing for 9v (on J4 for example or J25) I don't get 9v. On J4 I just read 0v and on J25 I'll sometimes read around 5v (which drops down to 0 eventually). I don't have any chips placed in their sockets yet, but wanted to figure out why I'm not seeing 9v before placing them. Thanks!

I'm building an MB 6582 and am about to put in my Mouser order for the control surface components. I noticed on a lot of the build guides it is recommended to order a 1/8" stereo audio output jack but I want to use a 1/4" stereo jack since my headphones use the larger stereo plug. Can someone recommend a 1/4" stereo output that will suit the MB 6582 project? If it can be bought on Mouser that would be preferred :).
