A brief vacation...

I bought my Aillio Bullet R1 roaster in January 2019. It was designated V1.5 instead of V2 because it was delivered with the infrared temperature sensor and the same power board used on V1 Bullets. Aillio had a design replacement but it was stalled in production for whatever reason. I planned to upgrade from V1.5 to V2 by replacing the power board when it became available. Great plan but...

By April 2019 they started delivering Bullets with the new power board in both 120 VAC and 240 VAC versions. But then they found production issues after a few hours of roasting use. I had been in touch with Julio at Sweet Maria's (Sweet Maria's was my source for the Bullet) and he said the 240 VAC model seemed ok, but it might be too soon to upgrade my 120 VAC Bullet since some of those boards were having a problem: "You're better off with what you have".

Aillio gave user's a heads-up on their Community site back in Oct 2019 that apparently some components for the 120 VAC version  had been ordered without including their application-specific requirements. This roaster gets pretty hot during use so you can't use just any old parts. About 3% of the new boards were failing. The biggest change on the power board is that it's much more efficient so probably doesn't get as hot during operation.

Aillio got it worked out and cautiously started delivering new boards in new machines, but they withheld upgrades to go from V1/V1.5 to V2 except in a very limited number till they were sure they had production right.

Then it started getting hot here in AZ and I started having an alarm go off. Apparently the code it generated indicates the internal comm bus had failed. The failure was always brief (about 1 sec or less) and I never lost a roast because of it, but it scared the crap out of me every time it happened. The thinking was it could possibly be the power board (since power usually went to P0) or it could be the control panel.

Matt at Aillio had worked with me for over a month trying to resolve the issue and finally felt they had to do something. Aillio & Sweet Maria's is shipping me a new V2 power board as an upgrade plus a new control panel PCB (it's the PCB that has the microprocessor which controls everything in the Bullet) as a warranty replacement in hopes this resolves the issue. I may chance another roast on Saturday, but I'm pretty much out of business till the new components get here (next week?) and I can get them installed.

Uh-oh... the 'season' has started!

We (mmm... I!  ) drifted thru the whole summer and didn't give much thought to it ending. Hard to realize summer is officially over in about 10 days when we are still hitting temps in the 100s! But there it is.  Cruising-friends-turned-RVers who publish conchscooter.blogspot.com are in the Southern hemisphere dealing with van renovations. That's about as close as we get to being on the road. Well- not counting driving to appointments in Tucson. Appointments in Benson don't count as the engine hardly gets warmed up before we arrive!  -----------------------  And today, as I type this post, is the 25th anniversary of 9-11 . The Admiral and I were in the Herrington Harbor Marina in Maryland on that infamous day. We were prepping Goosebumps so we could leave for points South. We needed haircuts and made our way across the street to the shop where we went mid-week. We stepped inside and were greeted by some very somber faces. The staff had the TV on and we stepped in abo...

'Tis the season...

 ... to sweat ! And complain. A lot.  It turned hot. Then this week it eased a bit. But it's coming back very soon! Hard to remember to check on sunrises and sunsets but here are what I managed to put together... Sunrise off to the Southeast... ... and a sunset off to the West (where else?!) The craziness in Washington DC has caused annual visitors to disappear from the park early as fuel prices climb to all-time highs. If you have a big 40'+ motor home or you're pulling a heavy 38'+ 5th wheel, either of which sucks up the diesel fuel, you need to take precautions to minimize fuel expense! Diesel was priced at $4.99/gal this week.

Monsoons? What monsoons?!

Every year I go through this anxious anticipation. "When are they ever going to start?!" Then that is followed by something like "when will this ever end?!" It's kinda' like how they joked about it in circa 1950s USMC: "there are only 2 good duty stations: the last one and the next one!" In the mean time life plods on and grocery prices rise faster than Social Security checks. A few years ago the Admiral was paying something like $100 - $175 for the week's food & necessities from Safeway. Now she's paying about $400 for the week. Yikes! And no, we aren't eating a different mix of food: we've been on a (sort of) vegetarian regimen since October 2013- it's called a pescatarian diet: veggies plus cold water fish (like salmon) once or twice per week.  Update: The Admiral shopped at Safeway today (23 Jul 2026). Sockeye salmon was $27/lb. They don't even carry king salmon. King salmon is caught of the coast of California and ...
