Great, high performance mosfet. It is originally made for heated beds of 3d printers, but you can use it wherever you need to switch larger currents.

2nd batch of these great little display panels. I use them one everything to display program results. I use the Greiman oled (small) library. Works just great without using much memory. I'll bef buying more of these soon.

5Pcs Development Programmer Board For ATtiny85 / ATtiny13A / ATtiny25
US$5.87 US$11.99

Q: I'm using 1.8.3 Arduino IDE and I installed the AT tiny drivers with the board manager (Mellis library). I select the USBtinyISP as the programmer and all I get is "Could not find USBtiny device error. Any suggestions as to what to try? Thanks Bruce

Cream5 This is just a expanding board, for the driver, it is depending on the chip on it.

I bought this programmer and the USBASP. This works perfectly with the Arduino IDE environment. All I did was wire the programmer to a ZIF (zero insertion force) socket and plug in the USB cable. I compiled the standard "blink" program, selected ATtiny85 as the computer and processor and used the USBtinyISP programmer selection in the "TOOLS" menu. It worked perfect. Nothing to change on the programmer, just plug it in and it works! You'll notice on the photo that I also have a MEGA 2560 as a programmer. Big time overkill now that I have the USBtinyISP programmer. But it was interesting to compare both. Actually the price ($7) is about the same for both. But I think the USB programmer looks cool! Now I'm on to programming ATtiny85 on the small breakout boards that you see in the photo. One format has a removable 85 socket and the other has a SMD 85 permanent on the board. It's realy nice working with these parts when they work straight away.
