Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision (2% or less), 5-band resistors. Hover above the tolerance for min. and max. range values. If you want to find out the color bands for a value, use the tool on the left. Standard EIA Decade Resistor Values: E6 series: (20% tolerance)10, 15, 22, 33, 47, 68 E12 series: (10% tolerance) 10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82 E24 series: (5% tolerance) 10, 11, 12, 13, 15, 16, 18, 20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68, 75, 82, 91 E48 series: (2% tolerance) 100, 105, 110, 115, 121, 127, 133, 140, 147, 154, 162, 169, 178, 187, 196, 205, 215, 226, 237, 249, 261, 274, 287, 301, 316, 332, 348, 365, 383, 402, 422, 442, 464, 487, 511, 536, 562, 590, 619, 649, 681, 715, 750, 787, 825, 866, 909, 953 FAQs I have a 6-band resistor.

tonepad -- a resource for d.i.y. music projects Z VEX How to design valve guitar amplifiers Music Thing Homemade PCBs for Effects Pedal Projects Jun 22 This article looks at a common alternative method to using press ā€˜nā€™ peel transfers, hand drawn layouts, or routed boards. This will cover each stage of the process in detail, showing you how to get a good result. You need access to a laser printer, and some copper clad board. Because the normal methods of making a PCB can be relativly expensive, or quite crude (when hand drawn) this provides a cheap, accurate alternative. Firstly we need to look at the print out. We need to take this image and prepare it for printing. Many other sites will discuss the types of paper for the best results. Copper boards come in serveral different types. Once you have the printed PCB layout on paper, you can cut out a section of copper board. Line up the paper to an edge of the board, and mark out a line to cut out. Please use safety glasses if you have them. The next step is to sand down the copper board to remove the oxide layer and also any grease or dirt. The next step is to remove the paper.

Flexible shaft Flexible shafts are commonly used in plumber's snakes. They are popular accessories for handheld rotary tools, and integral parts of rotary tools with a remote motor, which are called "flexible shaft tools". They are used to transmit power to some sheep shears. They are also sold to connect panel knobs to remote potentiometers or other variable electronic components.

Tube Amp Schematics / Projects What is a Hoffman board? Hoffman boards are classic amp circuits that have been re-designed using my own turret lug layouts. I didn't invent the circuits, I just came up with a slick way to organize the circuits on super neat turret lug boards. What is a Hoffman board? Note: I don't sell complete Hoffman boards. Hoffman board manufacturers Hoffman Board manufacturing instructions Hoffman board installation Instructions Choosing a chassis for a Hoffman board Scratch building an amp Sound clips of some of the amps below Note: The layout diagrams in this section below are my own designs. I now offer the bare Hoffman style boards as pre-drilled boards with un-finished edges that need sanding. I created some new layout diagrams for the pre-drilled boards I sell. The old layouts are labeled - Layout diagram #1 The new layouts are labeled - Layout diagram #2 New stuff to read here Check out my new Parts List page.
