I discovered it not too long ago …
I have been using Hiren boot CD for a very very long time, but switched to medicat, it has everything Hiren has and some

I always just made my own flavor of hirens with just the apps I needed. I used a few different combinations of software but used Windows PE as a bootable Windows environment. But I made a dos bootable partition that had an array of tools like ram checker, hard drive tester, and virus scanner.
It worked great for what it was. Id update it every year or so but it made quickly diagnosing computer issues down to a science.

Do yourself a favor: if you order PCBs from JLCPCB or somewhere similar, make sure to tick the radio button for “assemble” if you need pieces assembled. Otherwise, two weeks later, you’ll get a shipment oh 25 PCBs with no diodes on them 
. Three more weeks till I can finish my awesome mouse because assembly and baking adds on to the timeline.
Oh no, you forgot to assemble? You didn’t notice you didn’t have to upload a bom or placement file?
Nope. I figured it uploaded as part of the zip file. Learned a $35 lesson that’s now $125 haha
If it’s any consolation I wasted 400$ because I forgot to select ENIG on an order when I was getting the production PM3 midboards made…
OUCH!
A means to an end. I inevitably have to do my taxes this year and I’m more scared to see how much I’ve paid for prototyping so far…
Currently working on modding an Intel NUC into a custom handheld PC… or that’s how it started anyways.
So far, this project has included 3D printing, forcing myself to learn CAD, some soldering, a multimeter, a touch of programming, and whatever random components and devices I had lying around.
Now instead of just a plain NUC, it’s a naked NUC with a poorly designed case, an onboard ESP32 running WLED to control internal lighting effects, and a removable Heltec V3 because why not at this point. Ignore the fact that it still has no keyboard 
Why did I do this? I realized recently that motherboards have spots that output constant voltage and wanted to see if I could integrate other low-power devices. Lots of cool stuff can be done if you tap into usb headers.
Anyways, here’s where it’s at so far vs how it started out. If any of you have cool ideas for this abomination, i’m all ears!

switch from a Heltec V3 to an NRF52 device and youll have immense power saving

This. My Wisblock mini ($30) takes up half the space of my Heltec V3, and lasts around 4 days off of a recycled 650mAh battery I had lying around. My Heltec only runs for like 2 days off of my month old 3000mAh.

i can barely push a Heltec to run off of a 18650 for longer than 12hrs
Definitely going to look into this. I’m still fairly new to meshtastic stuff so i don’t have much of a frame of reference yet.
I will say the first thing I noticed about the heltec when I got it was how short of a runtime it had with any of my batteries lmao
Funny enough, I keep one on my car dashboard with constant power. Several times it has killed my battery after not driving for a few days or unplugging it.
Yeah the esp32 is power hungry in the heltecs.
Made a keycap for my new keyboard’s escape key with some glow in the dark PLA and some UV resin. (Also using hall effect switches for the first time and OMG the difference)

@mirandahw asked for a 3d printable protector for the DT RFID Diagnostic Card, so I put this together.
Feel free to print for yourself and remix, hope it helps.

The new bambu labs H2D looks insane

The dual nozzle is cool, but all the attachment are not new … starting at $2K for a closed system seam a bit steep to me …
Edit: and $3,500 with the laser head

Hard pass on all the laser stuff for me… but the vinyl cutter seems like a neat extra
I have potential use cases for the dual nozzle set up to allow for me to print actual tpu not the rigid stuff… but I don’t think it’s worth it to me for just that
I am interested in the new single ams HT, 1, I might be able to modify it easier than a full ams to feed tpu… also the 85c seems very appealing
