Message-ID: <0a815c978259556ffc6cc40b8de94032dd983abf.camel@eml.cc> Dear all, I'm a little bit worried since there has been no status update for quite a while and little to no activity on this mailing list for over 2 weeks. I started working on my own PCMCIA EOMA68 module and still rely on the 3D-printed case and everything related to it (e.g., power supply). In general, any news would be highly appreciated. In particular, I would like to know how the 3D-printed cases are making progress. I saw some development towards a custom 3D-printer and what appears to be PLA printing attempts. Since I ordered a resin-based case (+$150), what is the status here?

Luke has been sooo busy he has been postponing his prolific posting habits (replying to me too). Expect nothing more from luke than something short that only somewhat answers the question that you were asking. This is just his situation. As for my status, (since you did ask why the ML was silent), I'm hand soldering an eDP connector. It is going poorly as the pins are so small that I had to buy a set of 20x mag glasses. These arrived 2 weeks late and bent, today. They do not fit either. They are too small. Augh. If that was not bad enough they have to be within 1/2 inch in order to focus. How am I supposed to work with that? Furthermore, the pins cannot be desoldered because the plastic connector becomes too hot and the pins fall out. I tried a low temp and then a high temp to shock the solder off with the same result. True, I could special order a 30pin eDP connector, but why spend $70 on a screen and then $50-$140 on a cable (alibaba est.), without shipping included?! I also bought a soldering stand, but it would not hold my very small pieces stable so I tightened the nut and the metal bent! I am tired of the stupid designs people keep inventing for inventors, so I bought a 6 arm plastic work piece holder. It works well, but heaven help me if I have to buy a replacement arm. They are so expensive (as was the the 6 arm work piece holder)! While I am working on the connector I decided to buy an adapter to connect the HDMI output of my SBC to a spare VGA panel. It has been a 10 days (6 business), since I ordered it and it still has not shipped... Well, I am upset at my circumstances but at least I am learning, right? I think I'll try using some solder paste and or a heat shrink in between the pins to prevent myself from cross soldering them. What I really need is to figure out, "What dissolves Rosin flux?" I tried acetone (aka. nail polish remover), dish soap, turpentine (aka. paint thinner), plain soap, and alcohol without effect. All the above were recommended online by a verity of clueless loosers.

I find that you have to nag them (three times!) about everything in order to get anything done. It's usually after the third nearly identical message that they figure out that you actually want them to get off their duff and do something useful... I really don't understand why they're like that -- it's like they care only about the money they're getting, and that whether or not they actually ship product is a secondary concern (let alone what condition it is in once it arrives...). I can actually recommend one particular seller -- they deal with driver boards for eg laptop LCDs, I got one for a Dell e6400 lid assembly from them -- they are under the eBay handle "ruohan666". They were extremely good, and when there was a problem (I /really/ should have removed that obviously spurious blob of solder before applying power to the kit!) they sent me a whole replacement kit, and did so rather speedily. But behavior like theirs is sadly the exception (and a grand one at that), rather than the rule. Also, I feel your pain with the DP connector -- I have a project I keep putting off because I don't think I can manage the 0.4mm pitch Hirose-clone connector involved. It turns out that the LCD in my mother's deceased Nexus 7 tablet has *almost* the same timings as that e6400 LCD, and I have the LVDS connector's pinout and a spare driver board. I don't need the inverter board because driving the backlight is as simple as wiring up 5v and a 100k pot. The two panels may or may not in fact be compatible -- I'd love to find out -- but that damned connector stuffs two rows of fifteen pins into a 3/8" long space... I'm pretty decent with the ol' iron, but I don't think I'm *that* good. For the record, the two timings that are out of spec on the Nexus 7 LCD are the front and back porches. ...and, as an aside -- if anyone wants to make a cable for my connector (it's Panasonic's AXT530124; Digikey has it; email me and I'll send you a picture of the pinout needed) and a cable for David, I'm sure we both will be eternally grateful. Depending on the time of the month, I may be able to Paypal a small amount ($10 or so) to help with expenses... I'm in North Carolina, USA, for shipping purposes.

You would coat the pins and pads in thick flux paste and drag a small ball of solder with a large chisel tip iron across the pins. Any unwanted bridges can be destroyed by heating them shortly. -- Ricardo From lkcl at lkcl.net Wed Aug 15 14:21:24 2018 From: lkcl at lkcl.net (Luke Kenneth Casson Leighton) Date: Wed, 15 Aug 2018 14:21:24 +0100 Subject: [Arm-netbook] Project status / 3D printing of resin cases?
