Activated #SOTA G/SE-008 and G/SE-012 on the Isle of Wight this morning with @rmc47 and @m0wut - now off to do a few more in G/SE to complete the region. #hamradio

Oh, @theRSGB! ... "Save £4.00 vs on the door price by buying online" then charges "£3.00" as an online administration fee. #hamr #rsgbconvention

<SARCASM> Thanks @silentnightbeds - your 2-man home delivery and assembly service was great! I always wanted my new £970 mattress 'assembled' in my hallway, as opposed to my bedroom! Now I can get directly into bed from the front door! </SARCASM>

It seems like all the cool #HamRadio folks are on @bluesky so I'll give it a go, too! I really can't take to Mastodon. I'll be at @m1geo.bsky.social if you're looking! 👋

Roofing by moonlight, ft. @rmc47 and @m0wut, with @dnas2 yesterday! The evening finished off with a light drizzle of rain! Hopefully it's watertight!

If nobody else has beaten me to it, making the ESP32 module on the PCB (eliminating the module) would probably work out well, as then the entire board could be made at the usual places. It seems to work reasonably well otherwise!

I built a few of the KV4P Android transceiver project boards, but they've not turned out too well 😕 The specified parts for the LPF don't fit the PCB and so the inductors are fragile (I dripped a bit of adhesive on them) and the ESP32 module specified isn't the right size.

I don''t expect anyone to want one of these, but if you find yourself desperate for an undersized coaster for your tea mug, check here:

Every once in a while, it's nice to make something that's simple, without crazy constrains, and just get it done! This time, a simple change to the classic Arduino LCD Shield to support (a) register reads (R/W# connectivity) as that's usually tied off and (b) 3.3V I/O for FPGAs.

I have spent a few evenings this past week putting together a simple FPGA implementation of the @Ben_Eater 6502 System on FPGA. Several people asked for the sources, so here they are: https://t.co/njmuwqRblm #retro #6502 #beneater #fpga

@UKPowerNetworks have been here most of the day. 4 vans and an offroad truck. The 1980s cable has a broken neutral about 30m from my house. They're currently waiting on traffic lights to stop the road and dig a hole. We've been waiting hours! If you live in Fordham: Sorry! 😬

Dishwasher was mid wash. And the car was plugged in (but not charging, already charged). Hope there's no damage to my toys! 😬
