"Precise" missile strike on apartment building in Kyiv last night. Another missile practically destroyed a house similar to mine. More than 14 are killed. Pursuing peace Β©, russian terrorists used more than 10 ballistic missiles, 20 cruise missiles, and many shahed drones.

3 a.m. Multiple strikes on Kyiv with ballistic missiles. It was extremely loud.

People are asking about #Starlink Mini voltages. Here is a map of primary voltages on the Starlink Mini PCB, CPU section. Input 12V converted to 5V. This 5V bus supplies power to all smaller voltage regulators. 0.7V is the CPU core voltage.

Working on some silly side project. Just for fun. This project involves a dual-core microcontroller, a bunch of sensors, a cooling system, a servo, and most importantly, a cardboard box.

A nice article by MIT, revealing how our Starlink volunteer activity in Ukraine operates.

Some people are asking what Starlink "revision panda" (rev4_panda_prod*, mini1_panda_prod*) is and how it differs from "regular" rev4_catapult and mini. Panda is simply the name of the new FEM (RF Front End Module) chip. It's a third generation of the FEM; there were Peanut,

It seems @NXP banned Ukraine. Unable to access the NXP website using multiple Ukrainian ISPs (we tested 4 ISPs). No issues when using VPN.

Got a phone call from Starlink. It seems that this APSU is defective, and they will send me a replacement unit directly to Kyiv. I'll do a full review after receiving the new unit. Thanks, @Starlink team, for the fantastic support.
Quite an unpleasant behaviour of the new #Starlink Advanced Power Supply. When both AC and DC are available, it switches to the DC, pulling full power + "phantom" 1.9 W from the AC line. I think it should prioritize AC and use DC only when AC is not available. Switching back to

An aftermath of last night's attack. I listened for humming and exploding Shaheds for half the night. Cruising missiles came at 4 a.m. as usual. But who cares.
Kyiv. Night of massive terror, Shaheds and missiles. Entire entrance of an apartment building obliterated. Two killed. Bodies under the rubble. This is what happens when Putin is given time.

Once again, my phone connected to someone's open "STARLINK" WiFi network, just in the middle of the traffic jam. Interestingly, the router's firmware is so outdated. Of course, I sent the "reboot" command to the Dishy. ALWAYS encrypt your WiFi.
