Direct Programming / Flashing via the Audio Socket. For Mobile Phone - Tablet - PC.Many small applications are ready for download - all ready for download - flash - run - or edit for own purposes.Interfacing any hardware to a PC is getting more difficult, as the options have been reduced mostly to USB and wireless - Bluetooth or WiFi. Many people describe the engineering situation as frightening, too many engineers missing - including the next generation, as children are not getting into it at a young age, learn problem solving in electronics and like this as option for studies and later life in a professional career.So, who will design the big electronic systems?Having had the opportunity myself, from the age of about 12 years, helped me to take this decision - never regretted it. And still at it as you can see.The Maker scene allows for may options - but often the cost in schools is too high to give everybody a chance to play with the kit, getting taught how to approach it, and take the final running application home.Here, Burkhard and Thomas really got down to a minimum solution - basically reduced to an 8-pin microprocessor.And how can you write programs for it? No problem - all of the tools are online and ree of charge.When ready, the software is compiled to a Hex-file. This file is uploaded, and sent back as a sequence of sounds, taken from the headphone output of PC, tablet or mobile phone. An old Walkman might come back to life.Sharing is very easy as well - online or send on a sound file. And this sound gave the project its name: SparrowAdding to the material while translating was one option I had - but my choice was to keep it all as is, and rather go for some addition at the end to some MORE. I added a bit of material to the original Book contents where I thought it might help
