Hi Jack! Yes these are the PEC11 series, metal shaft, etc. I'm going to disect a few soon to see how well detent removal surgery will work. ;) The ones with switch are PEC11-4225F-S0024, the only differences between these and the ones I stock are the switch and a 25mm long shaft instead of 20mm. I can go $1 each on these also with a 50 quantity order. Best! SmashTV

Hello all! I have added encoders to the lineup at the MIDIbox store, they are very high quality, made by Bourns. 6mm shaft, nut/washer included, typical specs for MIDIbox use (24 detent, 24 ppr) The same encoder but with an integrated switch can be special ordered from me also. Hopefully this will end the eternal quest for cheap encoders. ;) Also I have removed the handling fee for orders over $100. The usual $3 handling fee is still there for smaller orders, and I really hate to charge it, but that's the average that paypal charges me to process the money. It's more accurate/costs you less to cover the $3 this way than raising prices on everything to compensate. Shipping is (as always) actual cost. I'm still looking for cheaper (but still reliable) global shipping methods, so let know if you have a better way! For those just joining us my MIDIbox Store is here. There is also some good hardware info there on my site, with 3D build maps, etc. I do my best to support what I sell. Thanks so much to all my customers! SmashTV

Whoop my bad! They are read directly by the PIC, but -driven- with the MF module. Hard not to misunderstand with my babbling. ;) Best! SmashTV

Almost, the motorized faders are directly read by the core, so no AIN board is needed for just motor faders. If you want potentiometers, CV inputs, etc. then you need the AIN. The DOUT connects to the core to drive LEDs, relays, etc. You will need one or more if you use LED's on your control surface. The only MIDI connections are on the core IN/OUT. You should consider building a MIDIbox LC, it will have the advantage of working easily with most audio software without much setup, and it's plug and play in the sense that no firmware mods are needed to do what you want. The firmware programming is actually a 3 part process: 1) Burn bootloader with PIC programmer 2) Upload MIOS via MIDI IN on your box. 3) Upload chosen application (this could be LC, MB64, SID, etc) via MIDI IN on your box. Notice only the first step requires a PIC programmer, any future firmware updates are done without having to open up your box and pull the chip. That said I burn the bootloader for free for anyone who sends me thier chip and I sell PICs with the bootloader on them already for those who want to skip the effort of building a programmer that only gets used once. I hope this answers more questions than it creates! 8) Best SmashTV

Great! Let me know if you have any other questions.... Just a reminder, I wrote a online PIC ID calculator that can be found here. Best! SmashTV

I do it this way, resistor on the solder side of the board (10K from PIC pin to PIC pin) but anywhere is fine as long as it goes from RB5 to any VSS connection.I wrapped mine up to further reduce the possibility of a short. Best! Smash

Yes, it works fine. The CORE PCB's that I ship don't even have a J3 connector since ISP is not needed anymore. (My JDM kits still have the extra parts for ISP though, since some JDM's get used for non-MIDIbox stuff) Just add another 10k for RB5, no need to pull the one from rb3. Have Fun! SmashTV

Really sorry to be off topic here, but I'm interested in your application. Details like your light source, scanning equipment, etc. would be cool. :) I started using modified RC servos for all static scenes instead of solenoids and never looked back. Alignment is way easier from the front of house controller instead of standing over the platform listening to spotters on the radio. ;) Best! Smash

short answer, no (the loads served by each 7805 would have to be exactly the same and you would still have floating ground issues) Long answer, yes. A diode on the output of each reg would keep one reg from seeing the output of another, but the diode would cause a slight voltage drop (no longer 5vdc). This can also be compensated for by using the same type of diode between the ground pin of the reg and ground. (Same amount of voltage drop to ground=higher ground ref=each regs output back up to 5vdc.) You could use many regulators this way in a circuit to get 5, 10, or 20 amps out of standard regulators (but the bridge rectifier and amount of AC current coming in would have to change to suit) Also since your regs are not at true ground anymore they would need to be isolated (tabs not on a grounded heatsink, etc.) Check out this PDF, Page 3 for one implementation of this concept. I don't really agree with his choices for capacitors, but I doubt he was driving moving faders or audio circuits with this. ;) Let me know what you think and Have Fun! SmashTV

These are usually switching type power supplies, and that is a bad thing for MIDIbox use.See this thread for a past discussion about switching vs. linear power supplies. Best! SmashTV

Stupid? never. ;) I used to troubleshoot video game board sets that sometimes had 200+ chips spread over two double-sided boards. Most of those have a bypass capacitor from +5v to ground next to every chip. Trying to track down a short was anti-fun, considering that each of the caps tests like a short on the meter! Paranoid is good when dealing with electronics, unless you have tons of money and time to burn. Paranoid forces you to learn more than just what part goes where, that's always a good thing. :) Best!

Heya SounDuke What you are reading is perfectly normal. Each of these "inside 4" pins are connected to +5vdc through 10K pull up resistors, so the 20K reading you are getting is from two of these. See the green lines: Best! SmashTV

Whoop my sarcasm radar must be way off these days.... :)

I found the following on the Dontronics website: A modified JDM (with battery!) and a -good- USB->serial convertor should do the job. Any leads on Mac PIC programming software? It would be nice to do it without Virtual PC ;) Best! SmashTV

Just a guess, but it looks like the comparators are there to allow it to read at very low rpm/single step, as the motor probably would kick out a weak and strange looking wave (not square) without a buffer at very low speeds. It's also worth noting that this design at anything but very low speeds would probably cause huge amounts of noise on the power supply rails. Best! Smash

I was looking for something else, and came across this Vibrating VU meter design from silicon chip magazine 3 years ago. Best! SmashTV

A request button is needed when using vocal/speech feedback in a control system, otherwise it will instantly annoy you with babbling in your ear :P Sounds like she has enough to do ;) Have you thought about a pager-type device that vibrates with overload? Seems like a non-touch sensitive motorfader with a custom cap and tactile mounting surface could be a way. Should not be too hard to rig up a simple VU meter circuit that switches lines on a DIN module instead of driving LEDs, for eventual output via MIOS. This would probably need a "request" button also, otherwise I doubt the poor fader will last very long. ;) Just throwin' ideas... Best! Smash

Heya Roger! Have you considered using a speakjet IC in standalone mode? They can be programmed to trigger a spoken phrase or sound effect from one of it's 8 inputs, and it's capable of looping a chosen sound until another input happens (for tracking peaks that might happen when she is out of the room, etc.) You could grab a signal from the peak overload led on the audio gear, buffer it, and use it to trigger the warning device. Or you could grab a signal from each of the last 8 LEDs and have the speakjet speak the status of the LEDs when a button is pressed. Alternatively a MAX/MSP patch could be used to watch the level on a sound card's input, and speak the level on command, warn of overload, trigger external devices, etc. Just launching some thoughts at ya..... ;) Very interested in the direction you take on this, please keep us informed! Best! Smash

This is not a setting that the user can change, it's part of the setup of the YABB system. If Thorsten were to raise the log time, it would slow the forum down, take up more space on the server, etc. I can live with it vs. slowing down the server! Best :) Smash
