AVR High Voltage Programmer

The only way to re-enable Reset or SPIEN fuses on some older AVR chips like ATtiny13A, to allow them to be reprogrammed, is to use High Voltage programming (HVP) method. This was available on AVR Dragon, STK500 and STK600 but since these have been discontinued, there is a lack of suitable programmers.

So, what is now the best solution for AVR High Voltage Programming?

How to Program Arduino with AVR ISP Programmer

If you have been using Arduino to develop your code but want to move on to develop your own AVR based circuit or want to program your Arduino board with an external programmer to give more code space, you will need to understand how to use an AVR ISP or In System Programmer. This post covers the information you need

Where to find Arduino Hex files or Output Binaries

You can use a normal AVR ISP programmer to upload Arduino sketches to an Arduino board or to an AVR microcontroller in your own circuit, such as ATmega328P, ATmega8 or ATmega2561, but first you need to know how to find the hex files that the programmer needs. The Arduino IDE makes this as hard as possible for some reason. This post shows you how to find them and also how to make Arduino put them in an easier place to find in future.

Resurrecting Voloci Electric Motorbike

The Voloci electric motorbike was made and sold by Nova Cruz Products Inc. during the period 2001-2003. It was too far ahead of its time and production soon ceased, but there are quite a lot of them out there. Unfortunately, the firmware had a bug and could get corrupted and a lot of these bikes did not get the very last update that fixed this. Kanda have just been working with one such guy to help him resurrect his machine.
