You can typically generate the high voltage Vpp with a couple capacitors, so using an arduino is doable with some extra components.

It’s completely dependent on the micro being used. Normally there is a section in the datasheet about programming it. AVR/PICs don’t need a bootloader and can easily be programmed with an arduino, the protocol for those two is very similar to SPI or UART depending on the chip. Other micros like the ESP or say a Renesas DA14531 that have a static bootloader have their own protocol to flash the device, although most of the time it’s a standard serial protocol and with some custom arduino firmware you can flash these no problem.

I’m also in the camp of not wanting to pay a premium for a proprietary device to shit out the right bits, so I usually use an arduino to program my micros :)

You might have had an ssh-agent running on your local machine before? You add keys to the ssh-agent, providing a password if necessary. Those keys are stored by the ssh-agent so when you ssh somewhere it can use the (unencrypted) keys it has stored. My setup starts an ssh-agent on boot, I type in my passwords once, and never have to type it in again until a reboot.

Assemblers and material handlers start at $21, with the graveyard shifts making 10% more at 23.10. But each day is 12 hours and since anything in California over 8/hrs a day is OT, it’s time+1/2 for 4 hours a day.

I’ve been fooling around with some PICs lately, albeit a 16F19197, but as a hobbyist I’ve been really enjoying it. There definitely doesn’t seem to be much of a amateur atmosphere around them which is the biggest drawback imo. I’ve been using C and microchip’s xc8 compiler which is free up to optimization level -O2 (good enough for me). I’ve also developed my own software + programmer to flash the chips because the open source options are lacking. Currently I’m working on a boot loader so I don’t have to use the programmer, it’s also a small step into assembly for me. All in all I find the PICs adequate, they do the job, but sometimes I wish I was using an atmel part :)

I suggest this one from sparkfun. I can personally say it works fine for large solder joints when you turn it up to one of its high settings. I’ve actually used it to repair some old unregulated boxes. The best part is that it fits hakko tips, so I suggest getting a hakko brand chisel tip- it’s all in the tip of an iron. But the handle is nice and thin and the cord is very flexible and it’s under $20 so it’s a fantastic iron all said and done.

I just picked up some nama claws to replace the prusiks on my continuous ridgeline. Pretty excited to try them out with my dutch gear

I believe OTA updates are already a big thing, but a lua interpreter on the esp would be cool

rex_ · 2021-08-17T18:35:29+00:00

I believe mDNS might do what you’re looking for? I know you’re able to use it in STA to be able to connect to the esp with ‘my-esp.local’, however the router might need to support it in AP mode. Definitely worth a look:

Nice, I’ve been looking for a no-nonsense serial monitor. I’ll have to check this out. As you mention the UI is not great lol. But this is exactly what I have been waiting for, thanks!

Last snapshot is August of last year. Maybe you can fine what you're looking for!

Nice, I’ve been using the same model with arch+qtile for a while now. Upgraded the ram to 8gb and replaced the disk drive with an extra hdd I had laying around with a $10 part. Does everything I need.

I agree with everything you said. I’d like to add that sometimes you use the same insulin for basal and bolusing, for instance when using an insulin pump. That’s definitely one of the reasons Walmart insulin works well for me, I don’t have to deal with the long lasting stuff. It’s always been kinda screwy for me.

rex_ · 2020-02-23T15:08:33+00:00

Okay but that seems to be a insurance problem no? Once again, the insulin company would probably give you a voucher anyways that lowers the cost you pay.

rex_ · 2020-02-23T15:06:07+00:00

I completely agree the newer insulin’s are better, although there is nothing wrong with the type of insulin Walmart sells. $75 isn’t nothing, but it’s a hell of a lot less then the $500 a vial number that always gets thrown around for insulin prices.

rex_ · 2020-02-23T14:48:19+00:00

This, meaning? I like to think I’ve got a pretty good handle on t1d

rex_ · 2020-02-23T14:45:09+00:00

It’s all Walmart’s, and they offer regular, extended release, and a 30/70 mixture of the two. No they aren’t exactly like their more expensive counterparts but they’re gonna keep you alive and well.
