chicken 630 Posted February 10, 2017 Share Posted February 10, 2017 A MSP430F415 in a cheap fingertip oximeter from AliExpress Teardown here: http://www.kean.com.au/oshw/oximeter/ I wonder if that nicely labeled JTAG header is still functional. With 16K Flash and 512 bytes of RAM, this MCU is comparable to the MSP430G2553. Energia on an oximeter anyone? Addendum 2/28: I ordered an identical looking model off AliExpress. Unfortunately, it's no longer MSP430 inside :-( It's now powered by a STM32F030 ARM M0. Fmilburn and oPossum 2 Quote Link to post Share on other sites
Fmilburn 445 Posted February 10, 2017 Share Posted February 10, 2017 It is interesting that you posted this as I recently gave some thought to building one of these. TI has a number of reference articles about them, e.g. http://www.ti.com/tool/TIDA-00311 oPossum 1 Quote Link to post Share on other sites

RobG 1,892 Posted June 5, 2017 Author Share Posted June 5, 2017 I went to Sears yesterday to get my new lawn mower and I got a free gift, Kenmore Alfie Voice-Controlled Intelligent Shopper. The regular price of Alfie is $49, but they are now on sale for $25. However, if you are SYW member and you spend more than $25, you get one for free (expires 7/1/17!) BTW, I also found Alfie for $7.95 on Amazon (with free Prime shipping, even cheaper from other vendors.) What's the big deal about Alfie? Crack one open and you will find the following: CC3200R1 Single-Chip Wireless MCU (with W25Q32JV (32M-bit) serial Flash memory from Winbond and a chip antenna) TLV320AIC3100 Low-Power Audio Codec With Audio Processing and Mono Class-D Amplifier 3.7V 500mAh LiPo battery 12 WS2812B LEDs Other useful things are microphone, large speaker, 2 LEDs, 2 switches, and USB port In other words, IoT experimenter's treasure chest! Can't wait to hack that thing (there's what appears to be programming header on the board.) Rickta59, Fmilburn, Fred and 1 other 4 Quote Link to post Share on other sites
zeke 693 Posted June 5, 2017 Share Posted June 5, 2017 It even says ZEK on the CC3200! It must be calling me. Quote Link to post Share on other sites
RobG 1,892 Posted June 5, 2017 Author Share Posted June 5, 2017 Too bad you didn't grab one when you had a chance @zeke Quote Link to post Share on other sites
zeke 693 Posted June 5, 2017 Share Posted June 5, 2017 I didn't even know they existed until I read your post! Maybe I can use a freight forwarding service? Hmmmm.... Quote Link to post Share on other sites

chicken 630 Posted February 7, 2021 Share Posted February 7, 2021 Thought about this thread (and good old times on 43oh!) when I saw Big Clive finding an MSP430G2230 in a solar light 🙂 As usual, he discusses the circuit in great detail. Quite clever implementation of battery charging and brightness control. Quote Link to post Share on other sites
