My Maxim sample order for the MAX7219CNG+ IC arrived on Friday. The Maxim IC sample order program is awesome! These chips are quite literally factory fresh as they shipped directly from the Maxim factory in China to me, for free! Again, as I stated a few posts ago, please do not abuse this program. I [...]
Well, an oversized box with a Newark logo was waiting for me when I got home today. Inside were my 64 diodes for the Sparkfun button boards and a collection of parts for the Unsped Arduinome Shield. The keen-eyed Arduinome-head may notice the lack of a MAX7219CNG+ IC in the group. That’s because I used [...]
My first batch of Arduinome parts arrived today. I received my SparkFun buttons and button boards in their nifty shipping box. I also ordered 100 beautiful blue LED’s from eBay. I wasn’t sure how good they would be, but they are nice and bright and should work great behind those SparkFun buttons. I held one [...]
Well, not exactly a datasheet, but I did find some interesting information about the Panasonic EVQ-WTEF2515B encoder currently listed at Electronic Goldmine. I scoured the web looking for data on this item and finally found it in an old Digikey catalog. Digikey was kind enough to publish data about the encoder in their catalog and [...]
Would you pay $30.24 for this part? I don’t want to, but since the only place I can find it is RS Electronics in the UK and I need it to build the Polywhatsit, I might have to bite the Euro-vs-US Dollar bullet and spend money I don’t want to. Where did $30.24 come from [...]
Well, most of the parts for the Polywhatsit are a breeze to source with the exception of one: the 8-position BCD rotary switch. The originally specified part is a weird one. I’ve only found one supplier who lists the exact part and they are in the UK. If anyone is curious, here is a link [...]
Since I’ve been looking for Arduino sound, synth and MIDI projects to tinker with lately, I’ve started remembering all of the little chips and trinkets I’ve bought over the years and stashed in drawers, knowing that someday I’d get around to actually using them for something. Tonight, while rummaging through one of those drawers, I [...]
Man, for $0.99 each, I wish I could find the datasheet for these. I want to use them with the Arduino but I’m not sure of the pinout. I think I’ll order a bunch and try to figure it out. If I get it right, I’ll post my results. Side note: Come on, Panasonic! I [...]
