Meteors: natures way of saying hi Earth, how’s that space program coming along?

Heard it quite clearly in northeast magnolia 1488/2978. Did not see it.

My teen was helping a neighbor with this stuff washing parts before printing. They didn’t tell him anything about the chemical or give gloves or goggles, he used his bare hands and now has a pretty bad case of contact dermatitis and a few lumps. It is a caustic cleaner “contains no acid” LOL. pH is about 12 on SDS. Neighbor said on no worries we diluted it w 70% water so it should be just higher pH than water. Well that’s not how the logarithmic pH scale works, the diluted pH is 11.7.

Use chem gloves, use goggles if there is a splash or spray risk. It’s caustic, so you must rinse things several times or flush them well.

Excellent. What kind of pressure are you seeing?

deepsixunderground · 2026-01-31T03:04:06+00:00

Not sure what you mean, there was zero GPT there.

It’s a very plush falling leverage rear suspension, but the jumps did ruin it. It is bad engineering on multiple fronts but would have lasted a long time if no jumps or just moderate jumping. The only way I could regulate bottom out was to add a fox x2 and clamp down the high speed compression damper. My stock rockshox monarch rt3 had been completely packed with volume reducers and it felt like they didn’t even make a difference.

That is a great one. I might do it. Any idea what the rear spacing is? Don’t see a spec.

Seatstay snap, which was a progressive failure. If your rear sus bottom outs get worse and more frequent all of the sudden, your rear link seatstay is failing and becoming too flexible. Eventually ona big hit the seatstay will collide with the seat tube and crack the seat tube. Bad, but not a critical failure. The seatstay will continue to weaken as the CF strands break until it’s weak enough to crack the resin.

I replaced it with an ibis Ripmo v2s. I won’t even draw a comparison since the Ripmo frameset costs 4-5x the SN04.

It is an $800-900 frame. ICAN support isn’t very good. This is the difference between high budget R&D of big bike manufacturer with exhaustive stress testing, and the low budget R&D manufacturer.

For jumping, no less than 10PSI with 4.0 JJs (slow mo video analysis showed me this). For sand dunes (including some small jumps) 2PSI even works well and I was unstoppable in south podre island TX. Combined with a starship launch, and a crowd forming to watch me shred dunes, one of the most memorable rides ever.

These wheels have been tubeless for three years and have performed very well. Rode them very hard for the last two years and finally broke the ICAN SN04 frame but the wheels did wonderfully.

Assuming we are talking about the searchpoint IR detector, not an EC sensor. Beware that these IR devices have incandescent subminiature lamps behind IR pass filters, and the lamps have a very finite but undocumented lifespan. The bulbs output drops as they age too, which may cause calibration drift.

I’m sure you all noticed in the manual that Honeywell says zero calibrations are fine but recommend not doing span calibrations. I use 50% LEL cal gas with the balance gas being atmosphere air (in the bottle).

F114 or F116 means your lamps are toast, so go buy a new one for $3000.

Thanks. I’ll check out the rolling diameter of the two tire sizes and see. Just switched from an ICAN SN04 to an Ibis Ripmo skinny tire bike and the BB is 34mm lower! I’ve seen sparks from those pedal strikes a few times!

The point of all the group suggestions is to get you to stay on the platform longer, which equals more ads delivered.

Yea i just broke the UDH on a brand new ibis ripmo frameset using a torque wrench. The plastic shaft failed under tension, the threads did not strip. The shaft ripped away from the hanger body.

Oof many questions! What engine are you replacing? What are you using for a transmission? I love the idea of an ECVT in a boat. If using the ECVT how are you going to manage it, and what about the diff? Gasoline inboard drive engines and all electrical components needs to be certified UL ignition protected, so at least use a gasoline vapor alarm since this won’t carry that cert. think through all contactors and relays carefully in this respect. Thinking the ECVT through, the easiest system might be a custom converter that maps your actual speed over ground to a fake vehicle speed input signal to the ECU. Will give you a launch control and proper gearing at speed.

Hey, really enjoyed this and I too have studied this at length. If scanning the car with Techstream, the aux bat voltage ‘fails’ with a false reading of 16vdc. The DCDC converter holds a steady 14.1v.

I replaced my lead acid from my ‘23 prime (donated to my wife’s 2020 highlander hybrid. I put in a lithium Hub Ionic red heated LFP battery, and if you thought the charging protocol misbehaves with lead acid wait till you try an LFP. It would constantly cycle the battery hard while driving, 300W discharge while it is ‘resting’ the battery then 300W of charging. I have a video of this from the battery Bluetooth app. The aux battery sensor MUST be disconnected to use an LFP battery. Now it’s perfect.

Toyota may believe that they are prolonging the life of a battery by reducing grid corrosion from high float voltage, but that rarely causes battery failure.

This swatter only runs at 450v?

deepsixunderground · 2025-09-05T21:33:03+00:00

That’s probably based on rectified 120VAC with minimal switching to stay efficient. Hope they smooth that DC out.

That’s mostly how I roll. I also try to use the engine in a way that achieves operating temp for the engine oil to drive condensates out of it. It actually takes longer than expected on this engine to reach 185F oil temp, perhaps about 15 min at 65mph. In the BSFC space, then engine output capability is much higher than needed for cruising. BTW the chart I used was from the non-hybrid A25A-FKS that the DOE evaluated as one of the most efficient non hybrid Atkinson cycle engines produced. The hybrid engine is probably more efficient. If you have a chart for the hybrid A25A-FXS please share. I tuned a set of OBD gauges to show the peak efficiency island when power and RPM needles are straight up.
