Chi protegge gli innocenti se il lupo Γ¨ salito in alto?
Chi lo ferma ora
Lo sapete che il lupo caccia per primi i cuccioli, e voi glieli avete consegnati?

L'unica cosa che posso fare è trovare quella voce che mi ha condannato e mi vuole fuori di lì
Ascoltare piano il sussurro che porta alla luce
O alla fine

Cosa posso fare se il mio cuore Γ¨ abitato da un inferno?
Cosa posso fare se ritengo che Γ¨ giusto?
Cosa posso fare se voglio cacciare tutti e chiudere la porta?

DIY Reflow Plate Runs On USB Power Delivery
If youβre working with surface mount components, youβre likely going to want a reflow plate at some point. [Vitaly] was in need of just such a tool, and thus whipped up a compact reflow plate that is conveniently powered via USB-C.
This reflow rig is designed for smaller work, with a working area of 80 mm x 70 mm. There are two options for the heating elementβeither a metal core PCB-based heater, or a metal ceramic heater. The former is good for working with Sn42Bi58 solder paste at 138 C, according to [Vitaly], while the latter will happily handle Sn63Pb37 at 183 C if the dirty stuff is more your jam.
Running the show is an ESP32-C3-WROOM, which serves up a web-based control panel over Bluetooth for setting the heating profiles. Using Bluetooth over WiFi might seem like an odd choice at first, but it means you donβt have to add the hot plate to the local wireless network to access it, handy if youβre on the move. Itβs also worth noting that you canβt run this off any old USB chargerβyouβll need one compatible with USB Power Delivery (PD) that can deliver at least 100 watts.
If youβre needing to whip up small boards with regularity, a hotplate like this one can really come in handy. Files are on GitHub for those eager to build their own.
This isnβt the first time weβve seen USB-C powering a small reflow plate. Of course, if you make your PCBs self heating, you can sidestep all that entirely.
