  1. @@abecedarian You never said LC4357, @L.R.A did. You just mentioned a new Hurcules LaunchPad. I put 2 and 2 together and made a few assumptions (which may well be wrong)!
  2. So.. if it links in to this post then that would imply a TMS570LC4357-based LaunchPad. http://forum.43oh.com/topic/8412-new-hercules-lps-in-bound/ LaunchPads sometimes seem to follow along from the more expensive DKs and there is already a DK for the LC4357, so it wouldn't be a leap to imagine a LaunchPad version of this: http://www.ti.com/tool/tmdx570lc43hdk
  3. @L.R.A C'mon. You know you won't be able to stay quiet until the 10th! You might as well spill the beans now.
  4. @rocket4kids Sorry - just me getting things back to front. The existing MSP432 is M4F. We thought it might be M0 or M0+ at one point. I'll correct my post above.
  5. I looked back at our previous MSP432 sleuthing thread as I know we thought it might be Cortex M4F M0 or M0+ at one point. I've hardly had a chance to play with the MSP432 yet, so I'm happy to wait and see. There is a MSP432 webinar on June 10th but no clues there that I could see.

    The Marquee Clock

    What's the plan? Something like @Greeg's LED ring clock? Or just 12 LEDs to give you the time to the nearest 5 minutes - which if we're honest is all the accuracy we ever really need.
  7. They had to cram it in so they stayed under the free size limit in Eagle.
  8. Welcome. Fellow UK member here. I'd say that the best way to start would be to look at the sample code in MSPWare for the Launchpad you've got. They're show you how to use the various peripherals. I find that peripheral setup is often the most complicated and unintuitive bit.
  9. @@terjeio I'd definitely be interested in seeing your laser cutter. Mine is a DC-K40 converted for use with Mach3 but that means it lacks support for raster engraving. Sorting this out is on my long list of things to do. The only MSP430 is a G2553 monitoring coolant. (I've pretty much given up on the ESI version.)
  10. Yes, you should be able to. However I'm not sure the 432 available to purchase on its own yet.
  11. To be honest, most modern microcontrollers will fit the bill. You might as well choose what you like using. Personally I think this is a great supportive community and there are plenty of code examples shipped with the IDE so that give the TI stuff the edge. Dev boards are cheap enough that it might be worth trying a few to see how you get on. What's SBC?
  12. @@greeeg How do you find the 3020? I was thinking of a 3040 but since sorting out a new workshop I'm now tempted by a 6040 for the sturdier 800w water cooled spindle. I'm aware of the poor stepper wiring and drivers, but what's your overall view of the machine? I'll have to hold off for now because all the UK eBay sellers of the 6040 suddenly upped their prices by
  13. @@Lgbeno That TPS61020 looks interesting. The 10SON package isn't great as I like to etch my own boards. The TPS61097A looks nice though. I'll bear them in mind if I'm designing any battery operated boards.
  14. Just run mspflasher.exe from the command line (in the MSP430Flasher_1.3.3 folder). It should tell you what FET and MSP430 is connected and let you upgrade the FET. It's also used for flashing firmware - hence the name.
  15. MSP Flasher (rather than CCS or Energia) is the best way to sort out any firmware issues. It shows you what firmware you have and lets you quickly and easily update it. If you suspect the firmware does need updating then that's the tool to check/fix it for you. Whilst the IDE may do the firmware update I've found they can be a little flaky on this. http://www.ti.com/tool/msp430-flasher As far as Energia goes, I stay well clear of it so can't help you there.
  16. When I had both CCS 5 and 6 installed, I found that they could both insist that their version of the firmware was the right one. I found the easiest way to sort out FET firmware was to use the latest version of MSP Flasher. Be careful if you have an early version of that launchpad with the XMS430FR5969 chip. A FET firmware update can render it unable to communicate with this deprecated microcontroller. Later versions are fine.
  17. What you trying to make is a DC power supply. I'm sure it's well within your capabilities (if you follow the suggestions above) but it's been done many times before. Unless you have a particular interest in designing a power supply I'd suggest that you just buy a suitable one and spend your time on more interesting things.
  18. I think even very thin copper can't be cut with a CO2 laser. Copper is very reflective to IR. So much so that it's even used for front surface mirrors.
  19. @@timotet I did go off on a bit of a rant there, didn't I! Your Toyoda sounds like a good machine, but even that wouldn't be ideal with a laser stuck on it. It may be able to do rapids at 2300ipm but when lasering you may need to engrave at that sort of speed. Any decent rigid mill will have too much inertia to corner at those sort of speeds. It's just not possible to produce a 3-in-1 machine that isn't just 3 bad compromised machines in 1. It's one of those things that people try over and over again, repeating the same mistakes. It's a bit like all those conductive ink PCB printers th
  20. You need a very expensive Nd-YAG laser to cut metal. Hobby level lasers tend to be CO2 ones and limit you to cutting things like acrylic and wood or engraving glass.
  21. I've no idea if there's anything wrong with the code (and it look like Energia so not something I use). The reason I thought about that is that 2 calls seem to perform well and the third gives a problem. I'm guessing that the third request comes whilst the first 2 are being processed. Maybe it's blocked. Maybe it accidentally overwrites shared memory. Not basing this on anything other than a gut feeling as to something worth checking.
  22. @@timotet Nooooooooo... Anything that tries to be all those things will be bad at them all. So many times that's been promised and never been delivered. For instance mills require rigidity and small backlash under load (leadscrews are ideal). Lasers require speed (hence light weight and belts). They don't need Z axis travel but it's good to have largish X and Y. 3D printers need a larger Z axis but large X and Y aren't really necessary. All these things conflict. You're so much better buying separate machines.
  23. The easiest way to test 3D printing out might be to try a service like Shapeways. Their printers are a huge step in quality above consumer ones, but might be valid for checking your premise. As far a milling goes, you might be able to find someone to test it out. I'd be happy to try for you if it's something small so that it fits my tiny mill and shipping from the UK isn't impractical.
  24. I tried it yesterday evening (UK time) and it mostly seemed OK for me. Initial load was OK. Some refreshes missed the image at the top of the page. Some timed out. I can't check from work - maybe the port is blocked at this end. I'll take a complete guess that you're not handling concurrent requests well - i.e. the separate requests for the page content, image and favicon are tripping each other up. Just got my own CC3200 last night. Not done much with it apart from the demo and project 0. I doubt I'll have the time for a while either.
  25. My current mill is a *tiny* home converted Proxxon MF70. https://0xfred.wordpress.com/category/cnc/mf70/ I'm just setting up a large workshop so am going to get something bigger. Whilst I was initially thinking about converting a bigger real mill like the Sieg X3 , I realised that something more of a CNC router would really cover what I need. I'll probably go for a CNC 6040 from eBay, but the smaller 3040 is probably even better value for money. The electronics are notoriously rubbish but other than that they're very reasonable. Beware though - CNC stuff is one of those hobbies that su
