… a separate (usually parallel port) JTAG programmer. Intro to CPLDs When to use a CPLD Consider using a CPLD when a design calls for more than one 7400 series logic ICs. A CPLD will be cheaper, faster, and can be programmed with your ideal pin-out configuration for simpler PCBs. Use a CPLD in tricky designs …

… in parallel (+ to both +’s and - to both -’s) then the cabinet will be a 4 ohm load. If the two speakers are wired in series (+ to spk #1 +, #1 - to #2 +, #2 - to -) then the cabinet will have a 16 ohm load. In other words, parallel wiring halves the impedance of the speakers while series wiring …
… circuit breakers. Do not use more than one power strip in series. Verify the polarity of electrolytic capacitors BEFORE applying power to a new design. Whenever possible, power all equipment, but especially power supplies through the switched power on your bench. Switch the bench power OFF when you leave …
… a vacuum cleaner? Well folks, here is one of the problems with many of the power supplies Apple provided for their iMac G5 17 and 20 inch series computers. Apple iMac G5 Power Supply 17 Inch Model Figure #1 Just a brief update for those that have been out of the capacitor loop. About the time Apple …
… spin true on the hubs. Between the hub and the discs I use three small rubber O-rings. These allow me to make sure the disc is spinning true by tweaking the tension on the adjusting screws. I made a temporary jig and using a DTI (dial test indicator) was able to measure the run-out on the edge …
… the ignition switch should not be turned to the accessory, run, or start position with the ammeter installed in series with the battery terminal and battery cable as damage to the meter may result. Only turn the switch to the run position after first installing a shunt across the ammeter. A full option …
… and resistance to physical stress), then you’ve got a product that should run with many of the big boys of the handwired world. In addition, the types of components used in the circuit—meaning the make and quality of the resistors and capacitors—often vary widely according to price and construction …
… by the capacitors when they’re placed in series. I plan to arrange 15 of these caps in series, adding up to a total of 22500V it can handle. Using the formula above, I calculated that my transformer requires a capacitor bank of 0.0064uF. However, this is merely the Resonant Cap value …
… of Doctor Who Series 3 and then lots of ancient Doctor Who on Youtube. I also sanded down the headstock of the Frankencaster and lacquered a new decal on, so it’s now a Bitzer Partsocaster. I’ve never done this before but it came out OK. Still no pickup, annoyingly. I’ve discovered the wiring for two …
