    Help need with ground. I hooked this up to s string of six high power LEDs. The V+ and V- from the LED driver went to the device screw terminals. I then hooked up Vin and Vout rom my bench top power supply set to to provide no more than 24volts and 150mA. I wanted to start slow at first. Before attaching my arduino I wanted to test the circuit, but where to get 5v from the trip the MOSFET? I worried maybe incorrectly, that a battery wouldn’t share a ground with the power supply so the 5 volts coming from the battery could have look like anything on the C pin.
    So I opted to use sparkfun’s breadboard power supply stick. I powered ith with a 12v wart from the same plug as the power supply. I rogues with the same ground 5 should be 5 volts. And it seemed like it was for a second, the led lit up but barely. Then POOF the breadboard power supply blew up. Why did this happen ? What did I do wrong?

    Did you use this to control a dimmer that runs off of 0-10V analog?

    I have the new old version, err…. the one before this one with a 168. Can I upload the arduino bootloader to it? I bought an AVR dragon and was going to try to modify the firmware to debounce the buttons but I could never get it to connect-and I gave up. If I could upload the arduino bootloader it would make modifying the firmware that much easier. Good reason to make another go at getting the dragon to work.

    If you put a shield on top of the wing shield, it might be stable but if you want to use it just to give you screw terminals for all your pins, it isn’t stable. in fact the headers it came with were so long, I had to cut a ¼ of an inch off of them to get the shield to sit flat; otherwise it was pretty wobly. Once that was done it was reasonably solid. Wonder why the headers were soo long?

    You can place and solder components on both sides instead of just one.

  • Product PRT-08100 | about 4 years ago

    I must admit I borked about 5 of these before I could make a smooth connection. As the description says you need a soldering iron and some needle nose pliers. I’ve found it easier to work with them while still in the strip and only cut them free once connected. First note how they fit into the housing. Notice the very small springy piece of metal that will stick through the small opening on one side of the housing? that prevents the whole thing from sliding back out. If you look at the pins, starting from the strip end you’ll see a U-shaped channel, a little stop for the end of the wire and then the springy thing. It helps if you use the right gauge wire. Strip the enough wire so that there’s insulation just at the end of the U-shaped channel. First solder the wire in the channel, but not too much and don’t let solder run into the springy thing. Next crimp the U-shaped channel over the insulation and wire. last, insert the whole thing in the housing.

    jungledisk is great, especially the latest version with folder sync.

    Jungledisk client to access Amazon’s Simple Storage Service, a.k.a S3. S3 Costs 15 cents per GB per month. Jungledisk gives you automatic backup, a network drive, workgroup sharing, and the ability to sync folders across multiple machines and platforms (mac, pc, linux). Jungle disk is not free I don’t mind paying $2/month to protect my most valuable data.

    does anyone know which JST series this is? I bought this and the 4 pin JST but SF doesn’t sell the male connector and I don’t know which of the bazillion versions of JST to order from digikey

  • Product DEV-09215 | about 4 years ago

    okay, after trying to make my own cables I switched gears and bought some premade ones from the microcontrolershop. I use ann AVR dragon and they sell 6-pin 6-pin that work for all arduino and many avr dev boards.

No public wish lists :(
