I use 3M breadboards that I obtain from Mouser. Yes, they are triple the price, but they are durable boards, made in the USA, and I have had no issues with them, and couldn’t be happier with what I use.
The way I look at it, I can buy cheap stuff that will… disturb me, or I can bite the bullet and buy quality and be happy that it is one less thing I have to worry about.
News - SparkFun Gets a Cease and…
about 7 years ago
I have to agree that unfortunately, Sun Microsystems is in its death throws, and their legal department are probably trying desperately to find some reason to keep their jobs in the environment of layoffs.
I have worked on SunFire systems, in the Solaris OS and have a great deal of respect for the advances Sun has made in the computing industry, for Unix, and recently (more or less) to open source.
However, until I saw the cease and desist posting, I never once thought of Sun or Sparc when I was browsing or purchasing parts from your site.
Such a claim is beyond absurd, and only a mind that has wasted its years contemplating law could think otherwise.
I usually connect sparks with either 1. entertainment, or 2. something bad happening (also entertainment, to an extent).
I usually associate Sparc with a formerly great processor architecture which has essentially been Intel’d to death.
I suspect that some mysterious substance (mold, fungus?) must be growing in the coffee machine that serves the nitwits at the legal firm.
I recommend you report it to the Center for Disease Control before it spreads.

I am pretty disappointed with this unit. I have been bumping my head against it for 2-3 months, and it has a habit of either not being recognised when it is plugged in, or not programming properly once it is recognised.
I chalk this up to the design. Since the USB interface is implemented on the onboard AtTiny, rather than say, an ftdi 232, I think the fault lies in the USB implementation on the AtTiny.
I think it would be a good move to re-engineer this board before version 2 is released. $5-$10 more for the board would be worth it if it meant higher reliability.
As far as the overall quality of the PCB and soldering, I can’t complain. Just a design issue.

Neato, but do you have a breakout board so I can use this with a solderless breadboard?

This looks curiously “Radio Shack-y”. It reminds me of the first iron I bought from aforementioned store some twenty years ago.
Still, the price is low, so if you need something a little better than a nail heated with a blowtorch, this will probably do the trick.
If you are going to be doing any volume of soldering, I would recommend the cheap red Weller’s, or, for still more, the 50’s baby blue Weller’s.
Antex makes a good iron, if you are over in the UK or EU.
Otherwise, I would probably recommend Hakko or something similar.
Er… After a little more contemplation… it looks like your methodology may be preferable.
If right clicking and choosing install fails, go ahead and try the procedure I provided above.
No. To install the USB driver, connect the programmer to your windows box on the USB port, and when the install new hardware wizard starts up, you tell it where you have the driver saved. It is assumed that you already have the files unzipped…
You can also add the drivers by starting the add new hardware wizard manually, through control panel, before connecting the programmer.
In any case, there isn’t a program to install the drivers. You just have to point windows to where they are stored when it asks, and say, “here are the drivers”.
Using cut and paste to provide the filepath works nicely, but you can also navigate manually in the wizard to wherever you saved the drivers on your windows machine.
I received this same error. After recompiling with the programmer explicitly spelled out as others have commented, I still had the error:
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
After a moment I decided, I really don’t care about speed. It would be nice if the programmer would go wooshy wooshy and program my 328…
So, instead of the recommended command line in the product description, I used:
Z:\somedir avrdude -F -c usbtiny -patmega328p -U flash:w:blink_1MHz.hex
I ommitted the -B 1 command line option recommended in the product description
And the result:
avrdude: AVR device initialized and ready to accept instructions
avrdude: Device signature = 0x1e950f
avrdude: verifying …
avrdude: 262 bytes of flash verified
avrdude: safemode: Fuses OK
avrdude done. Thank you.
The result: one overpowered 20 mips 328 powering a blinking LED.
On to more exciting things…
