As a software engineer, I do not normally work with custom hardware/electronics, so I was missing all basic components required for prototyping and was feeling kind of stuck. I did not want to spend the farnell budget on “consumable” general purpose electronic components, so decided to buy from ebay some cheap passive components in bulk, and use the competition budget on things that make more sense to buy from farnell.
I ordered “kits” of resistors, capacitors, dimmers, cables, breadboards, etc…mainly sourced from shenzhen, very cheap, but took more than a month to arrive in Greece (vs ~next day delivery when ordering from farnell), so lost quite some time in the hardware department, but atleast I finally now have a nice collection of passive components to use in this and future prototyping.
210Pcs 25 Value 0.1uF-220uF Electrolytic Capacitors Assortment Kit Set
1000 Pcs 50 Values Ceramic Disc Capacitors Kits
15 Values 3296 Trimmer Potentiometer Variable Resistors Kit
560pcs 56 Values (1Ω–10M Ω) 1/4W 0.25W 1% Metal Film Resistors
Breadboard, cables..
MQ7 CO Carbon Monoxide Coal Gas Sensor
MQ135 Air Quality Sensor Hazardous Gas Detection
LM2577S LM2596S DC-DC Step Up Down Boost Buck Voltage Power Converter ( will try to use it for the CO2 NDIR Infrared sensor which needs 18v)
Cheapy seansors: Rain sensor, temp-humidity, LM35 (these are for arduino so I need to check 3.3v operation)
SOT23 MSOP10 SMD to DIP10 Adapter for testing the TI temperature sensor
and two NRF24L01+ 2.4GHz Wireless Transceiver Module (in case I decide to separate CC3200 from EXP430)
Btw, Wurth was kind enough to provide me with a total of five kits of SMD inductors and capacitors, so here is a photo of my son sampling them :-)
