On the IX board (for both the Menorah Kit and the Larson Scanner), there are 9 LED locations each of which is connected in series with a single resistor.
Could I increase the number of LEDs per output without significantly modifying the circuit? I was thinking that 2 per output wouldn't necessarily cause a problem, 3 possibly. Would it just be a mat…
i Purchased 5 preprogrammed ATtiny2313 for Larson scanner-extended chips. Is there an "Easy" way to determine which firmware is on each chip? I have a USBTnyISP AVR PRogrammer, I'm just not…
Now that I've built your newer (2313) version and your older analog one (555+4017), I'd love to better understand why the transistors are helpful. The output from the 4017 pin is passed through a 47…
Hi Gonzo,The Art Controller requires an incoming logic-low signal to trigger it. The DS3231 does have an alarm output, and it looks to me as though its output is an "active low" type that …
So, one of the local community colleges has a yearly thing where they offer simple courses for young kids of various ages, covering a variety of subject-matter. I'm wondering whether they need to ha…
The '2313 target board and the ISP shield both have the same orientation for the ISP header. In both cases the headers need to be installed on the tops of the boards, and you need to orient the cabl…
OK. I bought and built the ispShield and the 2313 target board. On the target board I installed a 6 pin ISP header with the leads facing upward and a 20 pin ZIF socket. I put positioned the jumpers t…
I went a little further and installed a VNC server on the Pi and a VNC client on my iPhone, now we have an autonomous EggBot which needs no external computer, keyboard, mouse or monitor -- it is all …
OK, I figured out a way to temporarily attach a little weight to the arm, and I'm right, it does make it work. I put a 1" #6 machine screw and T-nut on it, like this:
