    T-962 Reflow Oven

    After a few years with the toaster ovens, I recently upgraded to this T-962 Reflow oven that I picked up on eBay for $184. Not sure why I waited so long, I baked my first 3 boards printed with stencils from OSH Stencil and they turned out great. Highly recommended!

    T-962 Reflow Oven

    Yep, mine is very much set and forget too which is nice because with my last oven I accidentally put in a pcb and then went and made lunch. 15 min later it was a bubbly black smelly piece of trash. Its not perfect like Greg said but a hell of a lot better then what I was doing previously. So far I'm happy with the stock firmware but that mod is good to know if I want to dial it in further!

  3. Hi Everyone, I've been away from the forum for quite some time now. We just welcomed a third child to the family and work has also been very busy. People probably notice that analog.io has been sort of on the decline as well since I haven't been doing my best to keep up with all of the things changing inside Google Chrome. Anyway, personal update is not the purpose of this post. I've always been a big fan of MSP430G2553 and Energia. I was recently forced to branch out and try Atmel SAMD11 using this kit: https://www.mattairtech.com/index.php/development-boards/mt-d11.html At first it was a real struggle to get started. I loaded a bunch of examples in Atmel Studio and just stared at them puzzled. Their abstractions IMO are just over the top for configuring periphrials, I much prefer interacting with registers with the syntax that TI uses. After about 3 days of cursing and scratching my head I finally think that I'm ramped up on the part and am now pretty excited about it. The experience has caused me to dig into the innards of Arduino more than I ever have in the past. So with the pain behind me, There is so much about this part that is superior to old trusty G2553. 48MHz vs 16MHz 4k sram vs 512 bytes USB More serial channels (SERCOMS) Multi channel DMA Analog DAC Faster ADC with decimation to get up to 16bit res This interesting (at first frustrating) concept of an event system to route events between periphrials without CPU. All of this and the price is lower or about equivalent to G2553. On one hand I'm sad to move to a new goto part, on the other, I'm excited. Has anyone else gave it a try?

    Playing with Atmel SAMD11

    Yeah don't get me wrong, the event system is super cool, I'm sure with timers and ADCs and DAC you could construct some very clever systems that don't even need the CPU running. My thing was that My first task was to use the timer for input capture. It took me awhile to wrap my head around needing to configure 3 separate peripherals to do this when I was anchored how how it was all built into the MSP430 timer. For the record to do this you need to: Configure the PORT to mux the pin to the EXINT controller Configure EXINT controller to "generate" an event Config EVSYS to route the event to the TC1 module Configure the TC1 module to capture on this event But with time there will be plenty of stack overflows on this topic. Right now it is early days. Maybe there is a future where a chip like this replaces some of the hard logic components like SPI ADCs/DACs because it is cheaper and can be configures to sweep up a lot of stuff.

    MSP430G2553 with NRF24L01 Wireless

    Ahh good old nrf24. The radio is capable of transmitting 32bytes of data so you might as well fill'er up before sending. If curious there is also a fork of enrf24 for energia and g2553 that also will transmit BLE beacons: https://github.com/analog-io/analog_io_lib Sent from my iPhone using Tapatalk

    Quad Thermocouple BoosterPack (MAX31855)

    This is awesome, really nice work! Now it would be interesting to see a few more temp sensors scattered around the house to see how they lag the furnace temp Sent from my iPhone using Tapatalk

    Code not run when use external power

    Make sure RST is pulled up. On Launchpad it is being driven by the USB FET but depending on where you apply external power and your jumper config, the FET part if the LP might not be powered on. Sent from my iPhone using Tapatalk

    This Weeks Amp Hour

    I was lucky enough to be a guest on the Amp Hour this week. We talked mostly about analog.io but I made a special point to give a shout our to everyone here on 43oh! @@bluehash, I hope it helps grow the user base! http://www.theamphour.com/272-an-interview-with-luke-beno-of-analog-io/

  12. So I didn't make it to the next round, but thanks to everyone here on 43oh for the awesome support and help along the way! I posted my update here with some thoughts: https://hackaday.io/project/4648-analogio-a-full-stack-iot-platform/log/26290-didnt-make-it-to-the-finals In some ways it is a relief but would have been really cool to go all of the way. I'm currently seeing if any of the finalists want to collaborate and use analog.io as their cloud data service, we'll see what happens next! Also, in addition to the MSP430 Sensor node, I'm also finishing up an AVR based one. Some people just really prefer Arduino and AVR, don't want to discriminate! -Luke

    My Latest IoT Fail

    I thought that maybe some forum members would enjoy this cautionary tale that I wrote: https://www.linkedin.com/pulse/my-epic-fail-internet-things-iot-luke-beno It's kinda funny and has a happy ending. Also just a quick run down on how things are going with the 2015 Hackaday prize: Currently analog.io is ranked #35 with 56 followers, 5 comments and 29 Skulls. The top project has 443 followers, 56 comments and 161 Skulls. Right now it would take 55 Skulls to move to the 10th rank. 10 Finalists are going to be selected on Sept 21st. While the judging criteria is not based solely on these stats, they still provides a clear signal to the judges that people like the projects. I would ask very kindly, if you enjoy using analog.io, please, take a minute, sign up for Hackaday and help the project out.

    My Latest IoT Fail

    Sorry I guess that I was mistaken, the Finalist down select is 5 not 10. Here's a really awesome video regarding the judging approach: Fingers crossed! My fear is that I didn't succinctly enough describe my project for someone to come in cold and get a good idea of what it is. It can appear a little random with some of the stuff that I posted. Regardless it is all that I could muster. Formally Skulls do not play much of a factor in the final selection but like all things human, I think that they have a very strong subconscious bias when seeing rank. Thanks google...

    Well that is that, semifinals judging deadline was at 3:50pm today. Now it is in the hands of the judges. The project is currently at 97 skulls and 177 follows. Have been swapping places back and forth with another great project. People can still skull and takes to everyone's help on the forum to get it to this point! Sent from my iPhone using Tapatalk

    Thanks! The Hackaday post put up a pretty big rally . 3 more days until judging begins, need to get my 4 min video rolling! Sent from my iPhone using Tapatalk
  21. Very cool! Regarding accuracy, one thing to keep in mind is that the delay function its self is likely clocked off of the internal DCO so its accuracy plays into your measurements. I'm curious if in your test you were to use a better clock reference such as a crystal, does the measurement accuracy improve? Sent from my iPhone using Tapatalk

    New MSP430 Wireless Sensor Node

    Thanks I'm excited and nervous at the same time! Of all of the days, I'll be away from my computer traveling so I sure hope that I can keep the site up!

    New MSP430 Wireless Sensor Node

    I've wanted to create a batteries included, very low cost wireless sensor kit for quite a long time now. I've made some attempts in the past but up until this point they were either too expensive to produce and too limited in expandability. I think that I've finally struck the balance that I'm going to be pleased with. The device is a little larger than a single AA battery, that is what it is powered off of. It has an NCP1400 Boost converter to bump up the voltage to 3.3V. The processor is MSP430G2553IRHB (32QFN) and it is attached to a HopeRF RF75 radio. There are 15 GPIO available through a 0.1in female header that is sandwiched between the battery holder and the circuit board. It plugs into a Launchpad for programming. Footprints are available to solder on a Si7020 temp sensor, a 32kHz crystal and two LEDs. I have the pins_energia ready and now looking at what it takes to make the @@spirilis enrf24 library work with it. I'll also create my own library with some analog.io tie ins as well as a special surprise. My goal is to sell these for $9.99 after I can get them debugged. Would anyone be interested in one?
