Subject description: Klee Sequencer Doc Library - Build Issue 6 Now Posted
|Note: This sticky is locked so that it can contain only one post - that will ensure clicking on this thread will always bring up the doc list.
It's been suggested that knowing the power requirements would come in handy when planning the Klee project. The power requirements can be found on page 3 of the build document. Here they are in a nutshell:
The electro-music Klee Sequencer has been tested using a +/- 12V power supply. It may or may not require an adjustment of the 6K8 current limiting LED resistors – 4K7 will work if brightness is an issue. However, the Klee has been most extensively tested at +/15V operation and it is generally recommended.
The electro-music Klee Sequencer draws around 100 mA per voltage rail at +/-15V operation, with a power dissipation of approximately 1.5 Watt per rail (3W total). A linear supply can be used, but it is possible to use it with an appropriate switching supply. In the case of a switching power supply, it is recommended that one use ferrite beads on the power supply lines connecting to the Klee Sequencer.
VTL5C3 found this site to be useful in dealing with building cables:

Issue 3 of the Build Doc has been removed - all of the below changes will convert a printed Issue 2 Build Document to an Issue 4 Build Document. If you have already printed an Issue 2 Build Document, and don't wish to kill another tree, print out the following documents and replace the listed pages. This will make it the same as the Issue 4 build doc linked at the top of this page.
Issue 2 Corrected Page 52
Issue 2 Corrected Page 76
Issue 2 Corrected Page 78
Issue 2 Corrected Pages 88 through 89
Issue 2 Corrected Page A-1
Issue 2 Corrected Page B-1
State Machine created some BOMs that contain actual manufacturer part numbers, though this was done before a couple of slight changes were made after proto test. This is what Bill had to say in regard to the files:
|OK, here are the Klee Bills of material. Just add (1) 100K 1% resistor and (1) 1K resistor to the BOM. I forget which board that was for. The rest is accurate and should be fine. Also, the 100K 25 TURN Potentiometer should be part number 490-2876-ND for the ANALOG BOARD BOM |
