Designing a Multi Node LED PWM Lamp


F0PPSLEFUI0X1FV.MEDIUM

Creating some blinky LED lights for Christmas has always been on my desire transcribe . Last Christmas season I really started pensive about building something. My elite concept was, each LED headlamp could smartly be connected to a pair of wires. The power to the LED lamps could be an AC indicate that would tom bola from a low frequency to a overripe frequency.

Audio looping & manipulation in RAM


IMG_4663

Sebastian built an seen leaflet /looper lap, resulting in some interesting pattern contortionism. [via]

This lap currently has a few ways to knead audio. These are:

  • A leaflet button allows the user to pattern incoming audio to a RAM buffer
  • A potentiometer sets the input merit
  • A potentiometer sets the pattern percentage / toss for playback. The changing of pattern percentage can be recorded if desired, by physically changing the adventure of the pot during count.
  • The lesson lines A0 – A18 can be manipulated ie. moved around, removed, replaced, giving a wide range of effects such as stuttering, repeating and fundamental granulation.
    Although this does not racket like heaps of manipulation, own in mind that this lap can wholly slash a racket beyond recognition. The ADC is running at its maximum throb, and as such the pattern percentage can be variegated greatly for pattern.

    BQ24040: Single Cell Li-Ion Battery Charger With Auto Start


    bq24041

    The bq2404x series of devices are highly integrated Li-ion linear chargers devices targeted at opening-fragmentary portable applications. The devices rule from either a USB port or AC adapter. The bad input voltage range with input overvoltage lee supports low-tax unregulated adapters.
