    Slugs Be Gone!

    It looks neater with some insulation tape covering the heatsink. I've got a few tidy heatsinks on order to try out next week.

    Slugs Be Gone!

    I've done a few more experiments. Heat from CPU board vs direct from original USB tab I tried insulating the copper strip from the CPU board and instead bridged across to the original USB port copper tab with a few layers of slugs-be-gone. This was useless and only gets 1GHz sustained. The...

    Slugs Be Gone!

    This morning I tried shortening the copper cold finger to be 70 x 30 x 0.5mm. This made the heat transfer worse and was back to 1GHz with short bursts of 1.5GHz. Dont shorten the copper! My thinking was that the CPU isnt at the end of the board and I want to reduce heat transfer to the...

    Slugs Be Gone!

    I wonder if the heat transfer to the battery is less on my Pyra because: - my case is slightly lifted away from the cpu board and I've still got a foam pad on the battery. - does the black plastic have a different thermal conductivity than the clear prototype cases? - Have the production cases...

    Slugs Be Gone!

    It depends how big a heatsink I use. This 10mm height one still helps and is only noticeable because its hot. 30mm high sticks up so get in the way a bit. Ideally. it would be more embedded in the case but I don't really want to start sawing big holes yet.

    Slugs Be Gone!

    Here's the next iteration of my thermal hacks. I've not broke the Pyra yet! This time I've fitted a cold finger to the bottom of the SoC. It is important to use Kapton tape to electrically isolate the copper finger from the SoC contacts! I also applied a layer of heatsink paste. The pyra has...

    Slugs Be Gone!

    The insulating foam is a very soft polyethylene foam, about 2mm thickness but it easily compresses. It holds the case plastic up a little further off the SoC. Something like this ebay listing or some "thermolam" polyester insulation. Does the pyra have a battery temperature sensor? I dont...

    Slugs Be Gone!

    I've had a look at the original copper strip from the SoC to the USB port. It comes with a nice copper heat-sink hat. I think the copper strip is supposed to be pushed down against the port when the case is on. I didn't notice the USB the port getting warm so I've tried applying a bit of...

    Slugs Be Gone!

    OK, so far no lockups for me. I've done the following: 0) apt update && apt upgrade 1) discharge cycle at full CPU load (building with "make -j2") 2) idle charge cycle. The lid was closed, back-light and key leds at half. The pyra was on a solid worktop with the copper tape in contact with the...

    Slugs Be Gone!

    ok, I'll test the idle stability, following your other thread, after my current build finishes. I'll try cold / hot with both discharging and charging. Should I stop MATE / panels for this test?

    Slugs Be Gone!

    The slug tape is an experiment to try to get more heat from the pyra to the outside world. The hottest surface I found, without taking the case off, is above the battery and the most effective way I've found to cool the pyra is to chill the battery. The top of the battery is always hotter than...

    Slugs Be Gone!

    OK, I've enjoyed a few days testing the Pyra now. I like lists so here you go... The following worked perfectly for me without any trouble: - charging when powered off (using an Anker IQ phone charger) ✓ - first boot ✓ - touch calibration (first attempt with one eye closed wasn't as good as...

    DBP repository

    perfect. thanks. I see that packages have long descriptions in the repo. Is this from the package [Desktop Entry] Comment or is it part of the upload process?

    DBP repository

    Hi sebt. I noticed the repo was down as I was about to upload a dbp for the rxi/lite programmers editor. (see github) Can you update the link about screenshots please? Lite is not in the debian repos. uses SDL2 and I like it. I think its a good example because it needs gl4es and I've got...

    Introduce yourself

    Hi, I'm Ian living in the north west of england. I'm checking in from a hot off the press pyra and, oh yes, it is gurt lush. I was brought up attached to my Dad's 8085 SDK, ZX80, C64, Amiga 500, 386 etc. and piped that into applied math with linux sys admin work. I now try to make...
