Today most chips are only available in SMD packages, therefore I often need adapter boards for prototyping. There are only a few manufacturer of adapter boards and they are often very expensive. I think the reason for the high price is, because most of this boards are made to replace DIL chips in devices with SMD ones. So this boards require a certain quality for this productive use.
For prototyping this is not my greatest concern. In most cases I am happy to get chips working and be able to experiment with them. I am aware there are many limitations on a breadboard, so the adapters do not have to be electrical perfect for my use. Spending $6-$9 per adapter, often for a single use, for a chip which costs only a few cents seems wrong to me.
Now I discovered, Adafruit has a nice set of SMD adapter boards in their shop. You always buy a set of three, six or even more, and they have different package sizes on both sides. It is exactly what I would expect from an adapter board for prototyping.
The boards left and right are the same. Just the front and backside of the same board.

I recently ordered a set of “PCBite”. These are special PCB holder as shown in the images in this post. To solder components into PCB I sometimes used one of this many “helping hands” products with two clamps, but they are no real use in most cases.
PCBite seems to solve some of the problems very well. You get a metal plate with a mirror finish and four of this cylinders which have a very strong magnet in the base. The middle part of the cylinder with the grip on is can be moved down and the PCB fastened that way. It is very solid and two would be enough to hold the PCB easily.
The mirror finish makes the bottom side of the PCB easily visible so you can solder on the top side and keep the component in view.
You can get you own set for $79 here, this includes free shipping. The quality of this PCB holder is outstanding. If you look at the close up photo, you see the perfection how this tool was made. I can really recommend this PCB holder.
Currently I am working on the final assembly of the Outmoded Sequencer, it looks very promising. There will soon be an update with all details about the final device.
This week the beautiful projects from Boldport club arrived. Each of them comes with a nice box or bag which matches the individual project. All electronic components to assemble and solder the project are included, but you need some external power supply and jumper cables to bring some of the projects to life.
In the following sections, I will show you some impressions of the assembled kits. My soldering skills are far from perfect, so even after cleanup you see a lot of impurity on the PCB’s. If you like to join the club, you can do this here.
This project is based on a project from 1974, which is a touch activated switch. The “Tap” project is combined with the “Cordwood Puzzle” for the LEDs.
I recently stumbled over the “Boldport Club”. This is a subscription where you get an unique electronic project for soldering every month in your mailbox. Each project is based on artful crafted PCBs and a couple of electronic components. You have to assemble everything by yourself, soldering all components together.
