    back then There were no electronics classes at school What a shame Later I somehow managed to build a score board for a friend of mine using all TTL logic LEDs and some NPN transistors I think I used decimal counter chips with BCD outputs and 7 segment drivers That s all hidden in the fog of time now Then came a decade basically without actively dealing with electronics well except for the classes I took at Uni and using oscilloscopes in the lab But that was more device physics than applied electronics solid state physics and that kind of stuff We tinkered with some atmel chips probably 8051 types and assembler I liked the electronics part but avidly hated assembler I m a physicist by education but during my time in the lab I strayed into IT and electronics I was managing the computer infrastructure of our department for several years We used Win XP clients a Samba server webserver wiki etc all running on a HP Proliant DL385 with an external raid 5 array UPS It had a whopping 1TB of storage and cost a fortune At one time we had a problem with some piezoelectric motors driving translation stages We should have known before but it turned out that these thing have terribly fine resolution but simply cannot be used to repeatedly and reliably position anything Their step size varies with temperature load condition of the lead screw time of day mood you name it I cooked up the mechanical parts to add quadrature encoders to these motors Our machine shop built it The electronics part was built by the electronics gurus I think they used an FPGA or similar to implement the counters and so forth That took about 6 months There were some issues that we just couldn t resolve quickly and to our satisfaction The simplest part was to buy an RS232 USB adapter Just by accident I had come across the Arduino project at that time There was a constant nagging feeling that I could build the PC interface using just that and resolve all of our issues 14 days later it was done All boxed up nicely too Nowadays I m mostly into LEDs Show me a device with many LEDs and I will probably like it All of that started when I came across one device that was sold by Sparkfun for about 60 That seemed overpriced to me and I build my own version of it You can find it on the projects page if you re interested The first prototype PCB was ordered at SeeedStudio As it happens they were working on a version of their own as well which is now known as the RainbowDuino I like to solder Sometimes I buy electronics kits just do some soldering fully knowing that the finished device will be idly sitting on one of my shelves most of the time It s quite addictive and also some form of therapy or
