One man’s e-waste is another man’s treasure.

Yet another mostly electronics related post, since I got some things donated the last few weeks I wanted to show here. What people just wanted to throw away, but what might be of good use to the AEBTB. One man’s e-waste is another man’s treasure.

1. Two 12 Volt 7.0AH lead batteries, out of an old Uninterruptible Power Supply (UPS) for some servers. Though used, they still may be useful for LED lighting charged by a small solar panel. They still measure well above 12V, though capacity might have degraded a bit. Got those a few months ago, but finally decided to take those heavy things home.


2. An abandoned aluminum “camera” case. Perfect to replace a carton I used for some electronics parts and projects, that I keep for future use and maybe show here.





3. Xilinx/Digilent Arty FPGA development board, with missing QSPI memory. The QSPI part was desoldered at work for some test or so, and this kit was just lying around and no one wanted to use it.



It could still be used with the USB/JTAG, but since FPGA are RAM based it won’t run without computer attached. OR such a QSPI has to be soldered back. That's probably not very costly. I did own a Altera Cyclone III Kit before, but since I didn’t use it because of other priorities. Thus I sold it a year ago.

Nice thing of the Xilinx is the Vivado software. Bundled with this board there should be a Node locked & Device-locked to the Artix-7 XC7A35T FPGA, with 1 year of updates. Need to figure how to obtain the license for this orphaned kit.
At least the Vivado tooling works quite well with Linux, giving it an advantage over the too much Windows oriented Altera(now part of Intel) FPGA software. Their Linux releases always felt quite untested and unstable. Bit like we have to provide it, but we don't give a damn. Not only the Altera brand is gone now, but also the open development community will choose differently and go for Xilinx I'd say.

Final note, bicycles are certainly not forgotten but I’m still in process of buying one or more new bikes. Can’t decide on buying either a new bike for my daily commute or a fun bike made of a reclaimed ALAN frame and a Gates belt drive. For both, don’t have the space or would need to take the ALAN bike indoor. According to Sun Ra: Space is the place.

ADR modules part 2, to recap or not?

Electrolytic capacitors have a wet dielectric which degrades with age and temperature. As a result the extremely thin oxide layers may become less isolating when stored over decades. Either the capacitor shorts or opens at some point, or just doesn't perform as good when it was new. Re-capping is the usual procedure to replace (all) electrolytic caps in restoring old audio equipment. The most common coupling capacitor value in these modules is 15uF / 40V. These smaller values might be replaceable with solid foil capacitors, though it largely depends on the space on the circuit board if this is possible and the cost involved. High-end audio nut cases (no relation to this blog) may spend top dollar/euro/yen on such things. Here it just has to be in line with the actual value of these units. So we will only use foil if the costs are limited. Otherwise just stick to cheap but good quality electrolytic caps. The likes of Nichicon, Panasonic, Vishay. Vishay bought a lot of the old Eur...

Kruishout - Marking/Scratch Gauge

And Now for Something Completely Different: the kruishout (Dutch), or you might know it as a marking or scratch gauge. This is an essential measurement tool in woodworking! Note the sharp needle or point on the left side of the beam. This is used to scratch a line in the wood. This specific one was from my grandfather. He was a carpenter specialised in making ship interiors. Carpenters can own multiple of these gauges on a project, so they only need to set them to a specific size and have less work re-adjusting constantly. Some variations may even use the tip of a knifeblade to actually cut a deeper line, e.g. when the grain is too strong to make a proper straight line. Or to actually cut very even widths of veneer. The Japanese or Chinese variants seem to use the knife tips. I’m not so much into woodworking at the moment, but this surely is a keeper! It’s also fairly easy to make some of your own. If you know a special use of this tool other than most uses shown on youtube, please...

A Story of Repair (SoR): Electric Kettle

One or two weeks ago, during the day, the RCCD (residual-current circuit breaker) tripped. The root cause was very unclear at first since no equipment was switched on or off during the event. Also the weather was quite humid and sticky after a thunderstorm, so that could be a factor as well. By unplugging some usual suspects one at a time, we could trace it to the culprit. First I unplugged the coffee maker from the mains, but again the RCCD tripped after some minutes. Next the electric kettle was unplugged, and bingo! The RCCD did not trip again. This Kettle, a Tristar HL-108B, has a base piece. This base did have my suspicion, since the inner wires became visible from where there should be a cable strain relief. Opening the base required special spanner or ‘fork’ style screws. Somehow they want to discourage repair, but they are wrong. With a suitable long bit style drivers it was fairly easy to get access to the wire terminals. The multimeter did not show any problems, but these kin...
