Computer geek turned Arduino fan. Wow, it’s suddenly so easy… electronics used to seem cryptic!

Geeky stuff is great. Whatever you like, have a passion for it!

  • Actually, for years I’ve been applying a small amount to the end of the iron and then touching it to the surfaces to join - it’s just a matter of not overdoing it. Especially for heat-sensitive components, I tend to tin the leads slightly, then apply a small amount of solder to the iron, and very briefly touch the contacting parts, and it makes a good smooth solid joint, even on small surface mount parts. I’ve modded my PSX, and later my PS2, installing a 17-wire chip to sub-1mm pads and leads from the BIOS chip with this method, and even replaced all the SMD LEDs in one of my cell phones - though I had to hold them down with the tip of a wire so they didn’t stick to the iron! This is with relatively crude tools too - a sharpish 25W non-adjustable iron I got for $10 years ago.

  • I was just complaining that it’s still a bit exotic trying to charge LiPo cells without a lab benchtop power supply… you guys are awesome. :)
    Would it be possible to make one of these for the 7.4V LiPo batteries you sell, or is that still too exotic? I can’t find a small battery or step-up converter that will drive a couple servos for any real length of time… 600mA is way too high it seems.

  • hmm, powered by an arbitrary high current DC power source… Looks like lithium batteries are still too esoteric and specialized to use without setting up an electronics lab.

  • Classy response to it! Anyone can sell your products, but it really shows that you have genuine geeks working there, and the kind of information you guys give out constantly isn’t so easy to imitate! At best, they could hope to mirror your site, but with all the guides and breakout boards you make, they’ll always be behind.

No public wish lists :(
