ISPnub is a simple to use stand alone programmer intended for flashing AVR controllers in the field directly in the target system or during production. The module has only one button and two leds as user interface.


- No external power supply needed. Uses voltage provided by target (1.8V to 5.5V).
- Programming counter. Limit possible programming cycles. After allowed cycles, no further programming is possible (module has to be erased/reprogrammed).
- One-button-programming: connect – push button – wait for red led off.
- Simple LED schema:
- green on = ok
- green blink = counter expired
- red on = programming
- red blink = error
- Define programming with simple script. Script converter generates HEX file for module.
- Load module with any ISP programmer which supports ATmega1284p
- 120kB memory space for programming data

Microcontrollers are, without a doubt, amazing little things. They are versatile, powerful, and extremely tiny. Unfortunately, the latter trait is also shared by both my wallet and my programming skills. My understanding of C is poor, and I can hardly afford to buy something like an Arduino or a decent ISP. And in any case, the Arduino would be overkill for many of my projects, which only need simple IC’s.

But as many of you know, DIY always finds a way. This tutorial is meant for those among us with no budgets or programming experience who want to start using these little machines. It is not based around the ATmega328 (the Arduino Uno chip), but rather the Attiny line of chips (the Atiny85 and Attiny2313, to be specific). The total cost of this project can go as lower than $15 if you know where to buy from, and you can still use the original Arduino IDE and language to program your projects in the end. Keep in mind that you will need some soldering skills to get this project done.

In this article read about how to build an AVR ISP Shield for Arduino. phenoptix writes:

This Instructable is for the build instructions for our new AVR ISP Shield Kit for Arduino. Its development owes a great deal to Instructables and our own community (particularly Nick!) and I hope to explain some of that along the way.

Let me start by saying to program an AVR chip with an Arduino you don’t need a shield or even a crystal if you’re programming Arduino bootloaders. But if you plan on doing it more than once a shield is going to save you some headaches as setting up a breadboard each time and then worrying about debugging is a pain…

Jie Qi from the MIT Media Lab and Bunnie from Studio Kosagi are hoping to crowdfund their idea for a new method of circuit building called Circuit Stickers.

A crossover between high tech and arts and craft, Circuit Stickers are not a serious prototyping tool but aim to find new uses for easily configurable electronics circuits so that they can be incorporated into other media such as books (basic science or fiction) or even wearable electronics.

Interconnect and power tracks made from sticky copper tape (or other conducting material) are laid out on any non conducting surface such as paper, material or flexible fabric. The individual components come ready-mounted and connect to the copper tracks via pads with sticky anisotropic (Z) tape. These can be peeled off later for reuse. There are two kits available containing a sketchbook to take you through the basics, colored LEDs, sound, light and trigger sensors and a tiny microcontroller with an ISP programming connector. That old Tee shirt looking a bit tired? Spruce it up with a running light display. [via]

The FabISP is an in-system programmer for AVR microcontrollers, designed for production within a FabLab. That is, it allows you to program the microcontrollers on other boards you make, using nothing but a USB cable and 6-pin IDC to 6-pin IDC cable. It’s based on the USBtiny and V-USB firmwares, which allow the ATtiny44 to perform USB communication in software. Programming can be done through avrdude

What’s with mint boxes and electronics? Beats me, but they are somehow made for each other. I had built ladyada’s USBtinyISP v1.0 circuit on a breadboard which I used every other day. It worked sporadically(and never at hour of need), used up half of my breadboard and looked ugly. So I decided to try my hand at home PCB fabrication and build it in, of course, a tiny tic-tac box. Since I was a beginner, the circuit is easy and single-sided and uses crystal instead of ceramic oscillator.

For relatively small (less number of pins than ATmega328) projects, ATtiny series, ATtiny45 or Attiny85 are good choice in terms of its physical size (8-DIP or 8-SOIC) and low power consumption. There are many ways to program it. One of the popular device is USBtinyISP and DASA. Both of them work very well with WinAVR (AVRdude).

Pedantite built his own Little Wire AVR programmer/tool:

The Attiny 85 has a neat feature that I had overlooked until I built this in that it has a built in PLL that lets you run the system off the internal RC oscillator at around 16Mhz. Many other AVR’s lack that PLL, and can only run at 8Mhz maximum without an external crystal.

USBTiny-MkII SLIM programmer (AVRISP-MKII clone) supports all Attiny, Atmega, and Xmega µcontrollers. It has three programming interfaces: ISP, PDI, and TPI. It works with AvrStudio or AvrDude. Small convenient board, contains double direction voltage translator for all interfaces and working from 1,2V, jumper for target chip voltage selection 5V or 3,3V (LDO stabilizer), and status LEDs. The heart of the device is a AT90USB162 controller with hardware USB, so it can provide fast programming speeds.
