There are a few new updates on the site. First, the Install manual for the remote Mixer PCB is up. Second, the instructions for painting the pointers on the 9mm potentiometers has been added, including a video demonstration.
Currently I am working on an install manual for the custom PCB Kit.
If you can’t see all the updates that have been added the past few weeks, including the additions to the documentation, install manuals, parts lists etc.. make sure to refresh you browser or delete temporary internet files.
[on a side note, I have found comments aren't working, I will try to get that up a running]
The last part for the x0xb0x custom PCB kits came on Monday and I have started packing kits.
I have also updated the Parts Lists and Bill of Materials sections of the website to include the new kits.
This PCB’s came in. I’ve already tested them in (3) x0xi0’s and it works great. I will be shipping these ‘mixer parts’ with all Full kits from now on. If you already have a kit just get in contact and we’ll arrange to get one out to you.
I’ve done several more minor updates to the site. One potentially helpful update is the support section. A few weeks ago I found the potential for issues with the potentiometers used for the the x0xi0 rear PCB. See the last note at the bottom of the support page
An RSS feed will be up for the blog in the next day or two so those of you with readers can get updates.
..a lot of work integrating the blog into the website. Here it is
I have post-dated a couple old news posts so that they would still be here.
I have also updated the Full kit install manual, fixed the Sitemap, and fixed numerous other minor things.
Also, the little x0xb0x mixer PCB’s came in last week but there was a mistake so the vendor rushed out some new ones that’ll arrive on Monday May 10th. Here’s what the part looks like..
I’ve ordered a large quantity of output mixer pcb upgrades for the x0xi0 Full kits. This has all but eliminated any clicking noises, actually even much better than a TB-303. This upgrade is for use with both my custom pcb and stock pcb’s. The new part will come with all future kits. For those with kits currently on hand the part will be very inexpensive (probably $5 incl. postage). More details will come when the production parts arrive.
I’ve updated the parts lists with larger pics of the capacitors.
I’m still working on integrating the blog into the website.
The last remaining back-ordered part for the 2nd run kits has come in. It’s the encoder for S2, it’s a high qulity Alps part with the correct shaft length. Also, most of the 2nd run kits were sent out with only one 3.3uF tantalum cap. Those of you with full kit serial #’s 124 through 144 will be getting the cap and the encoder sent by first class mail.
I’ve done a lot of work testing the x0xi0 kit signal-to-noise problems in relation to clicking sounds coupling into the mix output. Many people have asked about the clicking sounds and I have found that most kits that I have worked on to this point do have clicking problems to varying degrees. The TB-303 actually has the same problems but the signal level is down enough it’s not really audible in the main output. The clicks are coupled from the gate and trigger signals. The circuitry is close to the output mixer and the high frequency bouncing of the gate and the trigger itself can get into the mixer stage. Also with the x0xi0 kits there is an additional trigger circuit for the new envelope generator that can possibly do the same if circuitry is close to the VCA or output mixer. The further testing came about as I was testing the new mainboards when to my dismay I found I still had similar clicking problems even after paying careful attention to the layout. The outcome of this testing will be specific instructions on how to eliminate the problem with the x0xi0 kits for both the regular x0xb0x mainboard and the custom version.
I tested the stackup of the kit with the new mainboard and everything is perfect.
For those that are waiting the custom boards should be ready to ship soon.
