The only way to re-enable Reset or SPIEN fuses on some AVR chips like ATtiny13A, to allow them to be reprogrammed, is to use High Voltage programming (HVP) method. This was available on AVR Dragon but since this has been discontinued, there is a lack of suitable programmers.
So, what is now the best solution for AVR High Voltage Programming?

ISP or In System Programming is the best way to program AVR microcontrollers as it allows them to be programmed in circuit. This is easier for development, production and most importantly, for updating the firmware later in the field. The tool used for this is an AVR ISP.
Kanda have become distributors for Waveshare who manufacture low cost but high quality products. As well as a range of Arduino boards and shields, Waveshare make AVR microcontroller tools, Bluetooth, WiFi and Zigbee modules and FPGA development kits and programmers.
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

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.

AVRDude is free open source software for programming AVR devices. It is command line based but can be run from a batch or make file. It is the main programming utility used by Arduino software when the target board does not have a bootloader.
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.
