These are 12 volt, 33 amp switching power supplies suitable for a range of high current uses. We used them for a public art installation that we were hired to engineer and install and they performed admirably for 3 months. We powered more than 200 feet of WS2812 LED strips with a couple of these power supplies.
We have some new products to announce at Modern Device; the most exciting is the new version 3 of the Fluxamasynth Shield, a 64 voice polyphonic synthesizer for Arduino. We updated the synth to the new SAM2695 chip, much better filters, and a new microphone input. Check it out in the shop.
Future Technology Devices International makes many different TTL Serial to USB chips.
One model, the FT232R, is used in boards like the
The AdaFruit FTDI friend,
SparkFun FTDI Basic,
Modern Device BUB I and
Modern Device BUB II.
It’s not the cheapest, smallest, or most functional FTDI chip– just the most popular.
You’ll notice it has a micro-USB jack, instead of a mini-USB one. Micro-USB jacks have a bad reputation for coming off boards, because they have less surface soldered on the board. We spent a fair amount of time finding a micro-USB jack with extra prongs and adding vias to reinforce the smd pads. Our destructive testing of a few of these boards shows that our efforts to toughen up the boards were successful. The jacks take quite a bit of muscle to break, and we think they will stand up to abuse as well as mini-USB jacks.
Moving the header to the bottom makes the board even smaller, and saves us time in production.
Both LEDs are reconfigurable (should you want to reconfigure them) with FTX-prog
It’s the BUB you love, smaller, slicker and reborn with an all-new brain.

We picked up these nice Rigid RGBLED Strips from one of our suppliers for a good price. They contain 30 5050 RGB LEDs which seem to be standard super-bright LEDs, they are 12mm wide and 500mm long with headers every 50mm where they can be cut and soldered. The have nice polarized connectors and six inches of cable on the ends which makes mating them in series simple and quick and easy. Priced low enough that you could afford to take off the LEDs and use them on other projects (.20 ea). The resistors are sized to lend nice balanced white light that is not too cold in color, when powered from 12 volts. The 12V trace which looks to be about 60mils wide is mirrored front and back for extra current-carrying capability.
